Subj : DAY2SVR: Nws Storm Prediction Center Norman Ok To : wx-storm@lists.illinois.edu From : COD Weather Processor Date : Thu Jan 12 2023 17:28:55 ACUS02 KWNS 121728 SWODY2 SPC AC 121727 Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1127 AM CST Thu Jan 12 2023 Valid 131200Z - 141200Z ....NO SEVERE THUNDERSTORM AREAS FORECAST... ....SUMMARY... Isolated thunderstorms may occur across parts of the Florida Peninsula and parts of California Friday, but severe thunderstorms are not expected. ....Discussion... A highly amplified flow field aloft will prevail across the U.S. Friday, as a trough over the East maintains intensity as it moves slowly toward the western Atlantic. Meanwhile, a short-wave trough -- within a broader area of cyclonic flow over the eastern Pacific -- will move inland and weaken with time, though additional/embedded short-wave troughing offshore will maintain the overall amplitude of the cyclonic pattern. In between the two troughs, sharp ridging will move eastward across the Rockies and into the Plains through the end of the period. As the eastern upper trough advances, a surface cold front -- trailing from a deep low moving northeastward across New England -- will quickly clear the middle and southern Atlantic Coast region early in the day. The trailing portion of this front will move steadily southward across the Florida Peninsula through the day, likely clearing south Florida and the Keys by early evening. Ahead of this front, showers and a few thunderstorms will likely shift southward across Florida during the day. Though a stronger storm cannot be ruled out, any severe potential appears to be quite low -- insufficient to warrant inclusion of any severe-weather probabilities. Elsewhere, the only other potential for thunder evident within the CONUS will be across the northern and central California coastal areas, and possibly into the central Valley, as the aforementioned, weakening short-wave trough moves inland. ...Goss.. 01/12/2023 $$ = = = To unsubscribe from WX-STORM and you already have a login, go to https://lists.illinois.edu and use the "Unsubscribe" link.
