Subj : DAY3SVR: Nws Storm Prediction Center Norman Ok To : wx-storm@lists.illinois.edu From : COD Weather Processor Date : Wed Nov 08 2023 08:14:51 ACUS03 KWNS 080814 SWODY3 SPC AC 080813 Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0213 AM CST Wed Nov 08 2023 Valid 101200Z - 111200Z ....NO SEVERE THUNDERSTORM AREAS FORECAST... ....SUMMARY... Isolated thunderstorms are possible across South Texas and the adjacent Texas Coastal Plain on Friday. ....Synopsis and Discussion... Broadly cyclonic flow aloft is expected from the northern/central Plains eastward to the Northeast early Friday, with enhanced confluent mid-level flow covering much of the eastern CONUS. This troughing is expected to deamplify throughout the day as an embedded shortwave trough progresses quickly across the OH Valley and off the Northeast coast. The enhanced mid-level flow is expected to shift eastward as well, with the strongest flow off the East Coast by Friday night. Farther southwest, a southern-stream shortwave trough is forecast to progress eastward across the southern High Plains and then northeastward across OK throughout the day, losing amplitude as it does. A remnant cold front will likely be situated across the TX Coastal Plain, with most of the ascent associated with the shortwave well north of this boundary. However, moist southwesterly flow will stretch from northern Mexico across TX into the Lower MS Valley, contributing to very moist profiles across South TX and the TX Coastal Plain on Friday. Mid-level temperatures will be relatively warm, limiting overall buoyancy, but a few isolated lightning flashes are possible within the deeper convective cores. Across the northwest CONUS, a shortwave trough initially extending from southern British Columbia through eastern WA is expected to continue eastward across the northern Rockies and southern Alberta into southern Saskatchewan and MT. Another shortwave trough will likely move through southern CA by Saturday morning. Moisture will be limited ahead of these waves, precluding thunderstorm development. ...Mosier.. 11/08/2023 $$ = = = To unsubscribe from WX-STORM and you already have a login, go to https://lists.illinois.edu and use the "Unsubscribe" link.
