Reading the Inbound and Outbound Velocity

Velocity data measures winds blowing toward the radar, known as inbound, and away from the radar, or outbound. Greens and blues indicate winds moving away, while reds and oranges show winds moving toward the radar. Meteorologists look at winds on opposite sides of a storm to determine rotation and severity.

Identifying Rotation and Possible Tornadoes

Strong rotation shows up as areas of green next to areas of red, indicating winds blowing in opposite directions very close together. This couplet signifies the storm has strong circulation and the potential to spawn a tornado. During severe weather, meteorologists closely monitor storms for these signs of rotation by examining velocity data.

Estimating Wind Speeds

The brighter the color, the higher the wind speed blowing toward or away from the radar. Darker greens represent winds of 20-40 mph, while bright pinks can mean winds over 60 mph. This helps meteorologists gauge the intensity of thunderstorm winds and the potential for damage. Velocity data provides confirmation when damaging straight-line winds occur.

Tracking the Direction Storms are Traveling

Examining small scale changes in the location of inbound and outbound velocity couplets shows the movement of a storm. Generally, thunderstorms move in the direction of the mid-level winds. Meteorologists combine velocity data with reflectivity to forecast the path severe storms will take. This allows warnings to be issued along the projected path.

Nowcasting Storm Arrival Times

Meteorologists can use velocity data to estimate when storms will arrive at specific towns and cities. For example, if a storm is moving northeast at 50 mph, and is currently 20 miles southwest of La Crosse, it will likely reach the city in about 25 minutes. This valuable lead time allows for advanced preparations.

Identifying Areas Most at Risk

If velocity data shows winds rotating counter-clockwise on the southeast side of a storm, the most dangerous part of the storm is likely on that flank. Areas near that portion of the storm have the highest risk of experiencing a tornado or other severe weather. Warnings and take cover messages can be targeted to that zone.

Confirming Storm Weakening

Meteorologists watch for changes in velocity couplets that indicate a loss of circulation and weakening winds. If rotation speed and area shrink, it signals the storm is weakening and severe threat is lessening. This helps meteorologists make accurate warning decisions.

Identifying Areas of Clear Skies

Lack of inbound and outbound velocity signals in an area means no precipitation is present, confirming clear skies. Checking for open “velocity windows” helps identify locations that storms have passed or areas where clearing skies are approaching from.

Gauging Winter Storm Impacts

Strong inbound velocities can indicate heavy snow bands. The stronger the winds blowing toward the radar, the more intense the snowfall rate. Velocity data assists with estimating snow accumulations as well. By tracking movement, arrival times of heavy snow can be pinpointed.

Velocity Data Provides Storm Insights

Doppler radar velocity information provides meteorologists and the public a window into the inner workings of storms. By interpreting these winds, scientists gain an understanding of intensity, rotation, direction and timing of severe weather. So next time storms approach, use velocity displays to help gain weather awareness just like the pros!

By understanding a storm’s expected timing and impacts, people can leave early, delay their trip, adjust their route to avoid the worst of it, or make alternate transportation plans.

Here in La Crosse, we know heavy rain or snowfall can lead to flash flooding of low-lying roads. The weather service issues flash flood warnings when radar indicates intense precipitation over a short period of time. These warnings alert the public to avoid flooded roads which can be extremely dangerous to try and drive through.

Winter storms pose a different challenge, as freezing rain coating road surfaces with ice can create perilous, slippery driving and walking conditions. La Crosse radar helps predict where icy patches are likely to develop so transportation crews can lay down salt or sand to improve traction.

Real-time radar also assists with timing of road maintenance projects. Asphalt paving and road painting crews plan their work based on weather windows with no precipitation expected, using the radar imagery to their advantage. Projects can be efficiently coordinated this way to avoid delays.

When severe thunderstorms enter the forecast, the La Crosse radar is invaluable for tracking their path across the surrounding counties and towns. It also estimates the intensity of rainfall and hail activity so emergency managers can prepare for potential flood and wind damage. Citizens can take shelter if a storm with high winds or large hail is approaching.

Transportation planners even use weather radar data in long-term decisions, like where to build new roads and bridges. Historical radar maps help them identify flood-prone areas to avoid, route projects away from, or take preventative measures like building drainage infrastructure.

The bottom line is La Crosse’s weather radar provides actionable weather intelligence to keep traffic flowing safely and infrastructure protected during Wisconsin’s volatile weather. From snowplow drivers to construction crews to police and emergency responders, many groups rely on this technology every day. So next time you check the radar before heading out, think about all the ways it helps our transportation system adapt to whatever Mother Nature has in store.

Utilizing La Crosse weather radar alongside satellite imagery

Weather radar and satellite imagery each provide valuable data for forecasting. But when used together, they can give an even clearer picture of developing weather conditions. This combo approach is especially useful in the La Crosse, Wisconsin area for monitoring storms and planning transportation.

The local Next Generation Radar (NEXRAD) at La Crosse Regional Airport scans the atmosphere all around it, detecting the location and intensity of precipitation. It paints a detailed image of what’s happening at ground level in the skies above La Crosse county and surrounding areas. However, radar can be limited by terrain blocking and clutter from objects like buildings and trees.

Meanwhile, weather satellites orbit high above the earth, capturing continuous images of cloud cover, temperatures, and moisture content across large regions. This bird’s-eye view isn’t blocked by terrain and provides helpful context on weather systems before they reach the area. But satellite can’t see behind clouds or measure conditions close to the ground like radar can.

Together, radar and satellite observations create a more complete profile of the atmosphere. Forecasters and transportation managers integrate the data streams to better anticipate impacts on roads, rivers, railroads, and runways in La Crosse and western Wisconsin.

When tracking an incoming winter storm, radar shows where snow and icy mix is currently falling while satellite monitors the long train of clouds yet to arrive. This gives a timeline for when precipitation will start and stop at specific locations, which helps officials stage snowplows and prepare airports.

During severe thunderstorms, radar detects downpours and hail while satellite imagery helps meteorologists estimate the depth and organization of the storm’s clouds. This information helps determine the storm’s intensity and likely effects like flooding, strong winds, or tornadoes.

Satellites are especially useful for revealing fog formation that weather radar can miss. Seeing where fog banks are located lets transportation agencies know which roads and bridges may become slick or have low visibility. Pilots also use satellite fog detection to navigate safely at airports like La Crosse Regional.

Before major weather events, analyzing radar and satellite together provides a detailed look at moisture levels, cloud cover, wind shear, and instability in the atmosphere. Forecasters can better predict where storms are likely to initiate and intensify. This helps the public and emergency managers know where to be most prepared.

During active weather, the dual data streams allow meteorologists to pinpoint hazards and issue more targeted, shorter-term warnings. For instance, seeing a tornado signature forming on radar along with rapid cloud rotation visible on satellite can lead to a tornado warning for the immediate area at risk.

Viewing radar side-by-side with satellite also helps put the radar imagery in spatial context. Satellite reveals the bigger picture of weather fronts and systems to better interpret what’s appearing on regional radar views.

In the past, radar and satellite data came from separate sources and required manual integration. Now, the advent of dual-pol radar technology along with advanced computer models allows automated radar-satellite blending. This provides faster, seamless imaging with maximum accuracy for forecasters.

The bottom line is combining radar and satellite observations results in better forecasting skill than either can produce alone. This fusion of near real-time data from both above and below supports smarter weather-related decision making for transportation in La Crosse. The insights help keep travelers safe while minimizing unnecessary disruptions caused by Wisconsin’s most extreme weather conditions.

So next time you check the area weather and see a detailed loop of showers and clouds, know it represents an integrated look from satellites far above you and radars nearby. This comprehensive coverage empowers people across the La Crosse region to plan around Mother Nature’s ups and downs.

Limitations of radar imagery and supplemental weather tools

Weather radar is an invaluable forecasting tool, providing detailed real-time precipitation data to meteorologists and the public. But radar technology does have certain limitations that can be supplemented by other observations.

The NEXRAD radar serving La Crosse, Wisconsin offers high-resolution images of rain, snow, hail, and storms in the area. However, it has difficulty detecting precipitation very close to the ground due to the earth’s curvature. Radar also struggles to measure light precipitation accurately at a distance.

Radar beams can be partially or fully blocked by terrain like hills and mountains. This creates gaps in radar coverage that miss incoming weather. Buildings, trees, and other ground clutter also interfere with radar results near cities like La Crosse.

Since radar only scans horizontally, it provides limited information on the vertical structure of weather systems. Meteorologists can’t determine a storm’s altitude and thickness solely from radar data.

In certain situations like hurricanes and nor’easters, precipitation particles get trapped in a band of strong winds passing over the radar. This can falsely make the storm appear more intense than it is on radar imagery.

To supplement weather radar limitations, forecasters utilize other observational tools like satellites, surface weather stations, weather balloons, and citizen science reports. Each has strengths that complement radar’s weaknesses.

Satellites provide a top-down view above ground clutter and see over terrain that blocks radar. Visible and infrared satellite channels offer data on cloud height, thickness, organization and density that radar lacks. Satellites also detect lightning strikes associated with severe storms.

Dense networks of automated surface weather stations report conditions near ground-level like temperature, humidity wind speed, and precipitation accumulation. These observations fill in radar’s weak lowest scan area.

Periodic weather balloon launches measure vertical atmospheric profiles showing temperature, moisture and wind direction/speed at different altitudes. This helps calibrate radar estimates and identify conditions favorable for severe weather development.

Finally, trained weather spotter reports and crowd-sourced citizen data offer ground-truth confirmation of actual storm effects like hail size, wind damage, flooding, tornadoes, and snow totals.

By integrating radars, satellites, surface observations, upper-air balloons, and public reports, forecasters can assemble the most complete picture of current weather. They can also fine-tune and verify computer model forecasts.

Data from non-radar sources allows meteorologists to monitor for hazards even when they fall outside radar range, are blocked from radar view, or are misrepresented on radar. This supplemental data improves detection of severe thunderstorms, tornadoes, hurricanes, flooding, fog, and winter storms.

Forecasters use corrections from ground reports, satellites, and balloon soundings to adjust radar algorithms and filtering to improve accuracy. New dual-polarization radar technology also mitigates ground clutter issues.

While incredibly useful, weather radar alone cannot observe everything meteorologists need to issue timely, detailed forecasts and warnings. Blending radar with satellite, surface, upper-air, and field observations creates the best possible synthesis of weather data for tracking storms affecting La Crosse.

Future La Crosse weather radar system upgrades on the horizon

The weather radar system in La Crosse, Wisconsin has served the community well for many years, providing accurate and timely weather data to help residents, businesses, and government agencies prepare for and respond to changing weather conditions. However, technology continues to advance, bringing new opportunities to upgrade the capabilities of the La Crosse weather radar system.

One area prime for upgrade is the radar equipment itself. The current Doppler radar technology used in La Crosse has been in place since the early 1990s. Upgrading to more advanced dual-polarization radar capabilities would provide more detailed data on precipitation type and intensity. Dual-pol radar sends and receives both horizontally and vertically polarized pulses, allowing advanced signal processing to better determine the size and shape of precipitation particles. This leads to significant improvements in estimating rainfall accumulation and distinguishing between rain, snow, hail, and other precipitation types.

Upgrading the radar hardware will also improve radar sensitivity, increasing the ability to detect lighter precipitation. This is especially important for identifying developing winter weather threats. More sensitive radar can spot snow showers sooner, giving earlier notice of potential travel hazards. Enhanced sensitivity also improves detection of light rain showers that could impact outdoor events.

In addition to hardware upgrades, improving the weather radar software and integrating additional observing systems can boost capabilities. Advanced algorithms sharpen radar data quality and quantify expected errors. GPS-based total precipitable water vapor measurements and real-time local mesonet observations can supplement radar to improve rainfall estimates and storm cell tracking. Ensemble modelling helps forecast the probabilities of radar-based precipitation forecasts.

These software enhancements coupled with dual-polarization radar hardware would significantly advance the detail and accuracy of precipitation monitoring services, hydrologic predictions, and warnings of severe convective storms. Users would benefit from more precise short-term forecasts of thunderstorms, snowbands, hail swaths, and flood-producing rainfall. Decision-makers would have better observational data to anticipate and respond to weather impacts on transportation, utilities, agriculture, and recreation.

Of course, upgrading a weather radar system requires substantial investment. The station owners and operators, like the National Weather Service, utilities, and airports, will need to perform cost-benefit analyses. Thankfully, advances in solid-state radar transmitter technology are bringing down procurement and lifetime maintenance costs. And the societal benefits of enhanced weather monitoring capabilities are substantial.

With proper strategic planning and partnerships between weather radar stakeholders, the La Crosse area is well-positioned to reap the advantages of the next generation of weather radar technology in the coming years. Improving today’s radar systems will build a weather-ready community resilient to the impacts of hazardous weather now and into the future.

How La Crosse weather radar assists meteorologists with forecasts

Weather radar is an indispensable tool for meteorologists in La Crosse and across the country. The radar located in La Crosse provides detailed real-time data on precipitation and storm systems to help meteorologists make more accurate weather forecasts to keep the public informed and safe.

Doppler radar sends out pulses of microwave radiation and measures the strength and timing of return echoes to detect precipitation and calculate wind motion. This allows meteorologists to see inside storms and track the location and intensity of rainfall, snowfall, and severe weather like hail or tornadoes. Updated every 5-10 minutes, radar helps meteorologists monitor storm development, movement, and evolution.

La Crosse’s radar is especially important for tracking snow squalls and bands off Lake Superior that often impact the area in winter. High-resolution radar data shows areas of heavy snowfall to allow forecasters to pinpoint locations likely to see rapid accumulations versus just light dustings. This detailed view helps meteorologists provide more specific snowfall forecasts rather than just general averages for the entire region.

When thunderstorms threaten, Doppler radar detects rotational signatures associated with severe storms. Seeing mesocyclones and hook echoes on radar alerts meteorologists to the heightened danger of large hail, high winds, or tornadoes. Real-time radar monitoring has greatly improved lead time for severe thunderstorm and tornado warnings.

In heavy rain, dual-polarization radar capabilities provide enhanced data on precipitation type and intensity. This allows meteorologists to identify regions at greatest risk of flooding based on rainfall estimates. Flash flood warnings can be issued for towns and neighborhoods with radar-indicated extreme rainfall rates.

Radar also assists meteorologists with forecasting precipitation amounts. Quantitative precipitation estimation uses radar echo intensity, storm cell trends, and rainfall calibration data to calculate accumulated rainfall. This information helps meteorologists provide more accurate hourly and daily rain forecasts.

In La Crosse, local meteorologists use radar together with data from surface weather stations, weather balloons, satellites, lightning networks, and weather models. But radar remains the primary real-time tool for observing precipitation and storm dynamics to issue timely and relevant forecasts and alerts for the public.

While incredibly useful, radar does have limitations. Radar beams can overshoot light precipitation near the ground, and interference and anomalous propagation can produce false echoes. Radars also have gaps in coverage, especially over lakes and mountains. So meteorologists combine radar with satellite, automated weather station, and model data to create complete and consistent precipitation analyses.

Future dual-polarization and software upgrades will further improve data quality and integration with other observing systems. But radar technology will continue providing the core observational backbone for monitoring weather and issuing forecasts in La Crosse and nationwide.

The unique information provided by weather radar on the location, movement, and intensity of precipitation and storms makes it an indispensable tool enabling La Crosse meteorologists to better understand developing weather and provide more accurate forecasts to help people plan and respond.
