Subj : DAY1SVR: Day 1 Convective Outlook To : wx-storm@lists.illinois.edu From : COD Weather Processor Date : Sun Oct 15 2023 19:48:26 ACUS01 KWNS 151948 SWODY1 SPC AC 151946 Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0246 PM CDT Sun Oct 15 2023 Valid 152000Z - 161200Z ....NO THUNDERSTORM AREAS FORECAST... ....SUMMARY... Thunderstorms are not expected through tonight. ....20Z Update... The general thunderstorm area for far south FL and the FL Keys has been dropped. While shallow convection will be possible near the cold front as it moves southward into this evening, weak ascent and instability are expected to limit the potential for deeper convection capable of producing lightning. ...Dean.. 10/15/2023 ..PREV DISCUSSION... /ISSUED 1101 AM CDT Sun Oct 15 2023/ ....Synopsis... An initial wind shift and association convection has shifted south of the FL Keys and into the FL Straits. Farther northwest, the synoptic cold front (denoted by a narrow cloud line) will continue to move southeastward across south FL and the Keys this afternoon into this evening. Lingering low-level moisture and shallow ascent along the front could support isolated thunderstorm development later this afternoon/evening, but storm coverage will be rather sparse. Otherwise, a midlevel shortwave trough will approach the Pacific Northwest early Monday, but any threat for isolated lightning flashes will occur after 12z. $$ = = = To unsubscribe from WX-STORM and you already have a login, go to https://lists.illinois.edu and use the "Unsubscribe" link.
