Forecaster: Bill Murray
N THE WEATHER MAPS THIS MORNING: In the mid levels of the atmosphere, a trough extends from Minnesota to Texas. This trough will be an important player in our weather, providing lift as it pushes into the Lower Mississippi Valley today. The upper levels reflect the same trough to our west, with the most dynamic upper pattern back in the West. This action will stay north of Alabama later this week as a big subtropical ridge develops across the southern tier of states. That means warm and dry weather later this week. A big subtropical high will form off the coast of Northeast Florida and Georgia today, and it will act as a big pinball spinner, pumping moisture up into the South.
HOLIDAY FORECAST: With the lift and moisture in place, clouds will be heavy across Central Alabama today. Showers and storms will break out today and tonight as well. The rain won't be continuous, and the sun should be out at times. Highs today should be in the mid to upper 80s. For Sunday and Monday, showers and storms are still possible, but they should be fewer in number, and more scattered in nature. Expect a mix of sun and clouds both days with a high in the 89-92 degree range.
HERE COME ‘DA RIDGE: A ridge of high pressure should develop across the southern United States in coming days. : This will mean hot early September weather for mid-week with only widely scattered afternoon and evening showers and thunderstorms; highs will be in the low to mid 90s.
Occasionally cloudy; a few passing showers or thunderstorms.
Mixed sun and clouds. An afternoon storm in scattered spots.
Partly sunny. Scattered, mostly afternoon storms.
