Wet/Unsettled Weather For Alabama This Week

WET PATTERN DEVELOPING: Birmingham has received less than one inch (0.89″) of rain during the entire month of September, so conditions are getting pretty dry around here. In fact, the last day with over 1/2″ of rain was back on August 1. The good news is that a wet pattern is setting up across Alabama and the Deep South this week as the upper ridge weakens, move eastward, and a surface front approaches.

We will forecast mostly cloudy weather through Thursday with occasional showers and thunderstorms. While they will be most active during the afternoon and evening hours, some rain is very possible during the late night and morning hours. Rain is falling this morning over parts of East and Northwest Alabama.

Rain amounts of 1-2″ are likely between now and Thursday night, and highs will be generally in the 80-85 degree range, very close to seasonal values. The average high today for Birmingham is 83 (over average high doesn’t drop below 80 until October).

ON THE MAPS: An upper trough will help to push a cold front into extreme North Alabama Wednesday night, then down to near I-20 Thursday. Both global models last week advertised this front pushing down into the Gulf of Mexico, followed by a push of refreshing, cool air. Unfortunately now the models have backed off on the amplitude of the trough, and accordingly the front hangs up over Central Alabama. This means the really cool air will stay north of here, and we will be stuck in the low to mid 80s through Friday and the weekend as the persistent ridge begins to rebuild.

On the positive side, there is a very chance we have seen our last 90 degree high of the year.

FRIDAY AND THE WEEKEND: We will forecast a mix of sun and clouds on these three days with scattered showers and thunderstorms; chance of any one spot getting wet is in he 30/40 percent range each day. Afternoon highs will be generally in the mid 80s.

NEXT WEEK: Not much change, at least for the first half of the week, with partly sunny days, the risk of scattered showers and thunderstorms, and highs in the mid 80s. See the Weather Xtreme video for maps, graphics, and more details.

TROPICS: Subtropical Storm Leslie is in the middle of the Atlantic, far from land, and should dissipate by tomorrow night. Tropical Depression Kirk is a low latitude system; it could regain tropical storm strength as it approaches the Windward Islands late this week, but then there is a good chance it dissipates in the Caribbean due to strong shearing conditions. There are no systems near the Gulf of Mexico.

ON THIS DATE IN 1956: Hurricane Flossy clipped the mouth of the Mississippi River in the early morning hours of September 24, 1956… the storm made a second landfall as a Category 1 Hurricane near Fort Walton Beach and Destin in far southeastern Okaloosa County late that evening.
