James Spann: Tropical showers make for muggy days in Alabama

James Spann: Moist air blankets Alabama, keeps temperatures lower from Alabama NewsCenter on Vimeo.

YOU CAN WEAR THIS AIR: Dewpoints will remain sky high (76-79 degrees) across Alabama through Friday, and with an upper low drifting into Mississippi the overall pattern won’t change much. Generally cloudy conditions with occasional passing showers or thunderstorms, especially during the afternoon and evening. Heavier showers will drop lots of rain in a short amount of time, and we should remain below 90 degrees because of the clouds and showers. The axis of heaviest rain will be south and west of here over the next five days.

Interesting to note that precipitable water values will approach 3 inches across parts of the Gulf Coast region today and tomorrow, as high as it ever gets. A flash flood watch remains in effect for parts of the coast, including Mobile and Baldwin counties.

THE ALABAMA WEEKEND: The upper low begins to lose its identity, and weather conditions will gradually become a bit drier and brighter. Expect a mix of sun and clouds both days, with upper 80s Saturday and low 90s Sunday. Showers and storms remain possible, but they will be more scattered in nature, and mainly during the 2-9 p.m. time frame.

NEXT WEEK: Looks like some pretty typical August weather. Hot, humid days with scattered, mostly afternoon and evening showers and thunderstorms. Highs generally in the low 90s.

AT THE BEACH: Only about one to three hours of sunshine daily on the Gulf Coast through Saturday, with occasional showers and thunderstorms. Rain could be heavy at times, and a flash flood watch is in effect. Highs will be generally in the 80s. Expect increasing amounts of sun and fewer showers by Sunday and next week. See a detailed Gulf Coast forecast here.

TROPICS: Amazingly quiet for mid-August; tropical storm formation is not expected through the weekend.
