SPC Feb 26, 2022 0600 UTC Day 1 Convective Outlook

SPC 1200Z Day 1 Outlook Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 1142 PM CST Fri Feb 25 2022 Valid 261200Z - 271200Z ...NO THUNDERSTORM AREAS FORECAST... ...SUMMARY... Thunderstorms are not forecast across the continental United States on Saturday. ...Synopsis... Expansive high pressure and a dry, continental-polar airmass will limit thunderstorm potential across the CONUS on Saturday and Saturday Night. Weak elevated instability may permit an isolated lightning flash or two across southern Arkansas/northern Louisiana, but the weak instability and only marginally cold equilibrium levels should preclude any greater threat. Isolated thunderstorm activity may occur off the Oregon/Washington Coast as a mid-level trough moves through the region and temperatures cool aloft. However, the greatest thunderstorm threat is expected to remain offshore. ..Bentley/Weinman.. 02/26/2022 Read more CHECK UPDATE ZOOM GRAPHIC
