You can't have thunder without lightning!⚡️Stop by the CIWRO booth at the OKC Blue game on Tuesday to talk to our weather researchers about wind and lightning! Be a part of the demonstrations. @okcblue tickets start at $10 each: nba.com/thunder/weathe…

One Weather Picture. Many Critical Decisions. ⚡📡 The Multi-Radar, Multi-Sensor (MRMS) system combines data from radars and sensors across the country to paint a picture of what's happening in the atmosphere. @NOAAResearch @NOAA 🔗: nssl.noaa.gov/projects/mrms/

As a result of a nascent relationship between @UofOklahoma and India in weather, we had the honor of meeting the Consul General of India, Mr. D.C. Manjunath, last week @NWCNorman. In addition to leadership, he set aside time to meet with our researchers, students and postdocs.🌍

Blowing snow can drop visibility to near-zero, posing a serious hazard to both ground and air transportation. A collaboration between @NOAANESDIS and citizen scientists @GLOBEProgram is helping scientists better detect dangerous blowing snow.

CIWRO researchers along with others from the @NWS Warning Decision Training Division visited Lincoln Elementary in Norman to show families how to issue their own simulated severe weather warnings. @NWSNorman

CIWRO researcher Jami Boettcher shares insight into scatter spikes from hail cores in a recent episode of @weatherbrains. Why do these spikes occur, and why do the radar images result in high confidence that hail is occurring? Netcast: weatherbrains.com/?p=11498

We gave guidance on navigating fire weather in Bartlesville today at @okmesonet's OK-FIRE workshop. Content included case studies and interactive lab exercises designed for landowners, wildland managers, firefighters, prescribed burn associations and public safety officials.

StreamScope is a low-cost, low-power scanning LiDAR solution built with commercial products and components. It is intended to be co-located with other stream sensors, and it provides fully automated, robust cross-section and area estimation for shallow streams. #AMS2026

Missouri Dept of Transportation (MODOT) maintains a database of road closures related to flash floods. This dataset has been augmented by combining precipitation and streamflow data, with road vulnerabilities, preparing it for training road-closure prediction models. #AMS2026

Support exciting research in flash flooding, aviation weather, and winter storms. Integrate the NSSL flash flood routing model (FLASH) into the Warn-on-Forecast System (WoFS). Apply now: ou.edu/ciwro/careers

To all those who work to help keep us safe when the weather turns severe and deliver us the good news when beautiful forecasts are on the horizon, Happy Weatherperson's Day!

Anticipating where and when thunderstorms will develop is a forecasting challenge. A storm's first lightning flash can be identified from a space-based lightning sensor, so the origins of thunderstorms can be better studied and forecasted. #AMS2026

CIWRO researcher Daniel Tripp, who helped develop Freezing Rain Accumulation National Analysis (FRANA), spoke to Science magazine about how the use of the tool to measure winter storms is helping to create even more advanced technology. Read more: science.org/content/articl…

Measuring snow isn't easy. We rely on dedicated volunteers to measure snow daily with a ruler. We use these measurements to verify snow forecasting tools. To use them properly, we must understand how often snow is measured on time and how often rounding happens. #AMS2026

CIWRO scientist David Harrison has developed a suite of lightning prediction tools based on the new Rapid Refresh Forecast System. These tools help Storm Prediction Center forecasters predict when and where lightning will occur up to 60 hours in advance of a storm. #AMS2026

To improve ice accumulation estimates, we developed an algorithm that ingests direct measurements of ice accumulation at airports (ASOS stations) to bias the current freezing rain national analysis (FRANA). This new algorithm fills in missing parts of ice storms. #AMS2026

Freezing rain creates dangerous ice on roads & power lines. We found that forecaster-written weather reports add helpful details missing from freezing rain sensors but are inconsistent. Clearer, more standardized reports would better support research & forecasts. #AMS2026

Flash-flooding events related to the southwest U.S. monsoon raise predictability challenges. Case studies of quantitative precipitation forecasts from the Warn-on-Forecast System highlight strengths and challenges with monsoon convection forecasting. #AMS2026

The Warn-on-Forecast System offers NWS forecasters greater confidence in emerging severe weather threats beyond current warning lead times. Researchers are working to better understand how this info can best be integrated into existing workflows of emergency managers. #AMS2026

High-resolution instrumentation observed the passage of a tornadic QLCS from Norman, OK on 26 Feb 2023, noting a rapid change in near-storm environment. Analysis has been conducted to determine what impacted the rapid change, with two thermodynamic processes highlighted. #AMS2026
