Day 4-8 Outlook Day 4-8 Convective Outlook NWS Storm Prediction Center Norman OK 0252 AM CST Sat Feb 22 2025 Valid 251200Z - 021200Z ...DISCUSSION... At the beginning of the forecast period, dry conditions will be prevalent across the entire Gulf basin. Southerly flow and some moisture return will begin Tuesday and Wednesday before another cold front pushes dry air into the Gulf again early Thursday. This continued dry air across the Gulf will continue to limit moisture availability needed for any severe weather threat. Beyond D8/Sat there is a better signal for ridging across the central Plains and a

Thunderstorms remain unlikely through tonight. ...Discussion... High pressure will remain situated over the majority of the CONUS through tonight, with any appreciable low-level moisture well offshore into the western Gulf. While a shortwave trough will move across AZ and NM tonight, loss of heating should minimize lapse rates and instability there. ..Jewell.. 02/22/2025 Read more

The risk for thunderstorms appears very low across the U.S. today through tonight. ...20Z Update... A small cluster of elevated convection developed earlier today across the Brush Country region of south TX, with sporadic lightning flashes noted. This elevated convection was apparently driven by sufficient ascent/moistening near the base of the EML noted on the 12Z CRP sounding, and aided by a weak midlevel shortwave trough moving across the

The risk for thunderstorms appears negligible across the U.S. today through tonight. ...Synopsis... Early morning surface analysis places the center of an expansive area of high pressure over MO. This area of high pressure (and its associated continental arctic airmass) is gradually expected to shift eastward throughout the day as shortwave trough progresses across the central Plains and into the Mid MS Valley. This evolution will maintain low-level offshore
