Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0651 AM CDT Sat Mar 14 2026 Valid 141300Z - 151200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Severe thunderstorms are not anticipated today. ...Synopsis... An upper trough is expected to rapidly deepen over the northern Rockies this afternoon, resulting in steep lapse rates, cold temperatures aloft, and strong large-scale forcing over northwest WY. Despite cold surface temperatures, at least isolated thunderstorms are expected. A developing low-level baroclinic zone over MN/WI will be the focus for thunderstorm development tonight as the low-level jet strengthens. Much of this activity will likely be associated with freezing precip and heavy snowfall. Finally, scattered showers and thunderstorms will affect much of central/south FL, in a rather weakly sheared environment. ..Hart/Weinman.. 03/14/2026Read more

Day 4-8 Convective Outlook NWS Storm Prediction Center Norman OK 0350 AM CDT Sat Mar 14 2026 Valid 171200Z - 221200Z ...DISCUSSION...

Behind this upper trough, models indicate a large upper ridge will be situated over the Southwest for several days, with a northwest flow pattern across the Plains. Given this pattern, minimal appreciable moisture return is expected over the CONUS, and severe storms appear unlikely through Saturday/D8.Read more
