WASHINGTON, D.C. — The drought gripping the Potomac River basin has reached a historically significant milestone. The river flow at Point of Rocks, Maryland — a key monitoring gauge on the Potomac — has dropped to the lowest level recorded in 131 years of record-keeping. The gauge measured 3,460 cubic feet per second last week,…
SPRINGFIELD, Missouri — A textbook severe thunderstorm is producing one of the most visually striking radar signatures of the entire outbreak over Springfield, Missouri tonight. The KSGF radar at a 19.5-degree tilt — a very high elevation angle looking from approximately 3,000 feet up to 26,000 feet at the edge of the heavier precipitation —…
BIRMINGHAM, Alabama — The severe weather picture across Alabama has shifted favorably as of the 5:25 PM Central Tuesday evening update. A messy mass of rain and thunderstorms covers the Deep South, but no severe weather warnings are active across Alabama at this hour. The rain-cooled air that has settled across the state following the…
CHICAGO, Illinois — The first ten days of May are shaping up to be significantly colder than normal across the central and eastern United States, and the cold pattern carries direct consequences beyond just temperature.

TEXARKANA, Texas — A destructive hail threat is developing across the Red River region, Arklatex and Ozarks today, with atmospheric conditions that rank among the most favorable for very large hail seen this spring. CAPE values may exceed 5000 to 6000 J/kg across the core threat zone — an extreme instability reading that, combined with…
DALLAS, Texas — The Dallas-Fort Worth MetroPlex has been upgraded to a Level 4 out of 5 Moderate Risk for severe weather today — a significant escalation that reflects a concentrated zone of supercell formation taking shape across the metro this afternoon. The headline threat is large and destructive hail, with the most robust storms…
FORT WORTH, Texas — The supercell storms tracking through the Dallas-Fort Worth corridor Tuesday afternoon are not behaving like classic tornado producers — and the atmospheric science behind today’s setup explains exactly why. These are High Precipitation supercells, commonly called HP supercells or meteorological meatballs, characterized by extreme rainfall output with large hail cores embedded…
LOUISVILLE, Kentucky — At 7:21 PM Eastern, the Kentucky severe weather situation is active on three separate fronts simultaneously. Cells are beginning to bust through the cap near the Paducah and Murray corridor with the potential to quickly turn tornadic if they mature. The main show — a strengthening squall line — is on track…
