Subj : DAY2SVR: Nws Storm Prediction Center Norman Ok To : wx-storm@lists.illinois.edu From : COD Weather Processor Date : Sun Apr 16 2023 17:23:40 ACUS02 KWNS 161723 SWODY2 SPC AC 161722 Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1222 PM CDT Sun Apr 16 2023 Valid 171200Z - 181200Z ....NO SEVERE THUNDERSTORM AREAS FORECAST... ....SUMMARY... Severe weather is not expected across the continental United States Monday and Monday night. ....Discussion... A deep upper low centered over the Upper Great Lakes region early Monday is forecast to drift slowly northeastward across Lake Huron, toward the Ottawa River Valley. Broader cyclonic flow surrounding this low will continue to encompass that portion of the U.S. east of the Mississippi Valley. Meanwhile in the West, an upper low is forecast to linger off the British Columbia coast, while a short-wave trough rotating around the southern periphery of the low will move inland across the Pacific Northwest during the second half of the period. At the surface, a cold front -- trailing southward from a triple point in the vicinity of southwestern New England early -- will progress eastward across the western Atlantic, lingering only across south Florida. Meanwhile, a cold front is forecast to advance southeastward across the western states, as the aforementioned upper trough advances toward/into the Pacific Northwest region. Showers and a few thunderstorms are expected near and ahead of the front lingering over south Florida, while showers and sporadic lightning will also affect portions of the West in conjunction with the advancing storm system. Finally, isolated, high-based, diurnal convection is forecast to develop across parts of eastern New Mexico and adjacent western Texas. Daytime heating across this region will combine with modest low-level moisture returning northward on southerly flow on the back side of a Gulf of Mexico surface high, to yield weak afternoon destabilization. While a locally strong gust or two -- aided by evaporative cooling within the dry sub-cloud boundary layer -- will be possible, any severe potential appears likely to remain below the 5% threshold that would warrant any areal inclusion. Convection should dissipate through early evening. ...Goss.. 04/16/2023 $$ = = = To unsubscribe from WX-STORM and you already have a login, go to https://lists.illinois.edu and use the "Unsubscribe" link.
