Wet At Times Through Friday; Drier/Hotter Weekend Ahead

| July 21, 2021 @ 5:50 am

SCATTERED TO NUMEROUS SHOWERS AND THUNDERSTORMS: The overall weather pattern won’t change much across Alabama through Friday. Warm, humid days, intervals of sun, and a number of showers and storms each day, especially during the afternoon and evening hours. Stronger storms will dump heavy amounts of rain, and isolated flooding issues are possible. Temperatures remain below average, with highs in the low 80s today, and mid to upper 80s tomorrow and Friday.

THE ALABAMA WEEKEND: The long awaited pattern flip begins as a strong upper ridge begins to nose into Alabama from the west. This means a trend toward hotter, drier weather Saturday and Sunday. The sky will be partly to mostly sunny both days with only a few widely scattered showers and storms around. Chance of any one spot getting wet Saturday is around 30 percent, dropping to 15-20 percent Sunday. The high Saturday will be around 90, followed by low 90s Sunday.

NEXT WEEK: The upper ridge stays in place, meaning hot and mostly dry weather. Understand there will be a few showers and thunderstorms around every afternoon, but they will be widely spaced. Afternoon highs will be in the low 90s, maybe even reaching the mid 90s in spots… it will feel like summer in Alabama. See the Weather Xtreme video for maps, graphics, and more details.

TROPICS: The Atlantic basin will remain quiet through tomorrow. However, a broad, non-tropical low pressure system is forecast to develop off the coast of the southeastern United States by late Friday or early Saturday. Environmental conditions are expected to be marginally conducive for some gradual development over the weekend while the system meanders offshore the coasts of South Carolina, Georgia, and northeastern Florida. For now the chance of tropical development is only 20 percent. The MDR (main development region) of the Atlantic will remain quiet through early next week.

RAIN UPDATE: These are rain totals for the month of July so far this year, and the wettest Julys on record. This is data from the larger cities in the state with long term climate records. No records are in danger despite all the recent rain.
