Little chance of thunderstorms will exist across the country today. ...Synopsis... An amplified upper-air pattern will persist today, with a trough exiting the East Coast, and another dropping south over the upper MS Valley. At the surface, relatively stable air will exist due to high pressure and offshore winds over the Gulf of Mexico and western Atlantic. To the west, a highly amplified upper trough near the West Coast will move east, eventually reaching UT/AZ early Sunday. While cool midlevel temperatures will exist beneath this trough, winds veering to westerly with its passage will result in downward motion and drying across much of the region. Precipitation chances will be maximized early in the day, and forecast soundings indicate little instability present to support thunderstorms within the north/south oriented precipitation band which is forecast to dwindle. As such, less than 10% thunderstorm probabilities are forecast for today. ..Jewell/Moore.. 12/30/2023 Read more View the full article Quote Link to comment Share on other sites More sharing options...
