Subj : DAY2SVR: Nws Storm Prediction Center Norman Ok To : wx-storm@lists.illinois.edu From : COD Weather Processor Date : Mon Dec 02 2024 17:17:37 ACUS02 KWNS 021717 SWODY2 SPC AC 021715 Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1115 AM CST Mon Dec 02 2024 Valid 031200Z - 041200Z ....NO SEVERE THUNDERSTORM AREAS FORECAST... ....SUMMARY... Isolated thunderstorms are possible along the Texas Coast. No severe thunderstorms are expected. ....Synopsis and Discussion... Upper troughing extending from the northern Mid-Atlantic states into the north-central Gulf of Mexico early Tuesday is forecast to progress eastward off the East Coast throughout the day. In its wake, a strong shortwave trough is expected to drop through the Canadian Prairies into the northern Plains/Upper Midwest late Tuesday/early Wednesday. Strong surface ridging associated with a continental polar airmass ushered in by lead troughing is also forecast to shift eastward from the Mid-South into central Appalachians throughout the day. A reinforcing surge of cold air associated with the Canadian Prairies shortwave trough will move into the northern/central Plains and Upper Midwest late Tuesday night through early Wednesday morning. This overall pattern will maintain largely stable conditions across the central and eastern CONUS while also supporting easterly flow across the Gulf of Mexico, which will result in some modest low-level moisture advection into TX Gulf Coast. Additionally, low to mid-level flow will increase across this region late Tuesday/early Wednesday in response to a deepening surface low and large-scale mass response. The resulting warm-air advection could result in a few isolated thunderstorms along the TX Coast, beginning across south TX early Tuesday before gradually shifting northward throughout the period. ...Mosier.. 12/02/2024 $$ = = = To unsubscribe from WX-STORM and you already have a login, go to https://lists.illinois.edu and use the "Unsubscribe" link.
