Can we use AI to predict thunderstorm evolution? Recently published in @theAGU GRL, we refactored @GoogleDeepMind's GraphCast for regional modeling and trained it on @CIWRO_ / @NOAANSSL's archived Warn-on-Forecast System (WoFS) data.

Meteorologists are turning to AI as a quick, efficient alternative to traditional weather prediction algorithms. Now researchers including @MontePhD & @corey_potvin have extended this tech to cover localized extreme weather as well as global forecasts. eos.org/research-spotlights/…

🤖 How can AI help scientists predict thunderstorms faster? 🤔 A new paper from NSSL and @CIWRO_ discusses how WoFSCast, a new AI-powered model, can accurately predict how storms will evolve up to two hours in advance. ⛈️ 📝: inside.nssl.noaa.gov/nsslnew…

WoFSCast is the first AI system trained and developed to emulate a sub-hourly convection-allowing weather model (CAM). WoFSCast speeds up forecast generation versus WoFS by at least a factor of ten, from minutes to seconds. #AMS2025

Monte Flora: Future of storm-scale AI: generating large-member (100+) hi-res (~1-km) ensemble forecasts in seconds. AI system in the WoFS framework already can produce “closely matching” forecasts with far less computational burden than #WoFS (far faster). #31sls

🤔How can science provide more warning when 🌪️tornadoes threaten? The Warn-on-Forecast System, equips forecasters with critical information between watches and warnings, enabling them to give longer lead times in the face of severe weather and tornadoes. inside.nssl.noaa.gov/nsslnew…

Our paper on the usefulness of the "WoFS-ML-Severe" products examined during the 2022 HWT-SFE is available in EOR. This paper explores subjective verification, objective verification, and qualitative analysis of the participant's feedback. journals.ametsoc.org/view/jo…

🚨 Paper pre-print alert 🚨 It has been a long time coming and the real-time code isnt ready quite yet, but you can now read how we are estimating storm updrafts from radar data 📡⛈️(arxiv.org/abs/2310.09392) [Table 1 is messed up at the moment, will fix in the coming days]

🚨 New paper alert 🚨: a study of radar and environmental differences between hail-producing supercells with differing maximum hail size production. Led by myself, with substantive contributions from co-authors @murillomojo and @PSU_RadarMeteo. doi.org/10.1175/MWR-D-23-001…

Relationships between 10 Years of Radar-Observed Supercell Characteristics and Hail Potential

Abstract Supercell storms are commonly responsible for severe hail, which is the costliest severe storm hazard in the United States and elsewhere. Radar observations of such storms are common and...

This is very preliminary and non-QC'ed data, but a new wind retrieval technique I am working on using soundings and lidar data, shows that hodographs got quite big in Norman.

Tornadoes are common this time of year, but do warming global temperatures influence these severe storms? Dr. Kimberly Hoogewind, a research scientist for @CIWRO_, is featured in the @washingtonpost discussing the role between climate change and tornadoes.washingtonpost.com/weather/2…

WoFS is running today and over two domains! Switch b/t the two domains using the Domain pulldown. Also, check out the new options under the ML products tab! DISCLAIMER: These products are experimental, and care should be taken when interpreting them. cbwofs.nssl.noaa.gov/
