ACUS01 KWNS 220459 SWODY1 SPC AC 220457 Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 1057 PM CST Fri Nov 21 2025 Valid 221200Z - 231200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Scattered thunderstorms are possible across much of the Southwest, mainly from late in the day into the overnight. Limited activity may occur over North Carolina and southern Virginia. Severe thunderstorm potential appears low. ...Synopsis and Discussion... An upper low will move across northern Baja CA today, and will gradually weaken as it moves into AZ by Sunday morning. Cooling aloft with this system along with midlevel moistening will eventually result in widespread precipitation over much of AZ and NM, including a few thunderstorms. Given the elevated nature of the instability overnight, severe storms are not anticipated. To the east, a low-amplitude upper trough will move across VA and NC during the day. Low pressure near the DelMarVa will quickly move out to sea as a cold front pushes south out of VA and into NC. Here, residual dewpoints near 60 F along with daytime heating will result in minimal SBCAPE within a westerly flow regime, possibly supporting isolated thunderstorms late afternoon or evening. Strong deep-layer shear will support cellular storm mode, but instability and lapse rates do not appear to favor severe hail. ..Jewell/Halbert.. 11/22/2025 $$ |
