ACUS02 KWNS 210614 SWODY2 SPC AC 210612 Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1212 AM CST Thu Nov 21 2024 Valid 221200Z - 231200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... A few thunderstorms are possible along the Pacific Northwest Coast on Friday. ...Synopsis... A large, deep upper low will exist over the northeast Friday morning, and will gradually weaken as it drifts east through the period. Meanwhile, an upper ridge will slowly shift east from the Rockies into the Plains, while yet another trough pushes across the Pacific Northwest region late. Substantial northwest surface winds will maintain relatively stable conditions from the Plains to the East Coast, with no instability forecast over much of the CONUS. The exception will be again along the coastal counties of WA and OR, as strong cooling aloft occurs. Scattered low-topped convection will be most likely over the ocean overnight. A few thunderstorms may move onshore, but at this time the stronger shear farther north does not appear to overlap with the minimal instability required for a severe threat. ..Jewell.. 11/21/2024 $$
