CORRECTED FOR TYPO IN DISCUSSION ....SUMMARY... Thunderstorms are not expected Thursday. ....Synopsis and Discussion... A shortwave trough is forecast to rotate through the central/eastern CONUS upper troughing on Thursday, progressing cyclonically from the central Plains through the Mid MS Valley into the Southeast States and southern Appalachians. Another shortwave trough is expected to drop southeastward through the Upper Midwest early Friday morning. Progression of these waves will help maintain upper troughing east of the Rockies through Friday morning. Farther west, expansive upper ridging will gradually shift eastward throughout the day, ending the period extended from northern Mexico into western British Columbia. A strong shortwave trough will approach the Pacific Northwest coast, but is expected to remain offshore throughout the period. The surface pattern is expected to feature ridging centered over the TN Valley, resulting in offshore flow across the majority of the CONUS. Another surge of cold air is anticipated across the Plains, helping to reinforce the cold and dry conditions already in place. Easterly/northeasterly surface winds are forecast across the Gulf of Mexico, but the development of a weak surface low just off the south TX coast should preclude any low-level moisture from advecting inland. Consequently, any thunderstorms activity should stay over the western Gulf. Dry and stable conditions will prevent thunderstorm development elsewhere. ...Mosier.. 01/01/2025 $$ = = = To unsubscribe from WX-STORM and you already have a login, go to https://lists.illinois.edu and use the "Unsubscribe" link.
