James Spann: Scattered showers, storms form again today in Alabama
James Spann forecasts more of the same for Alabama’s weather through Friday from Alabama NewsCenter on Vimeo.
WARM, HUMID SUMMER DAYS: Alabama’s weather won’t change much through Friday. Look for warm, humid days with a mix of sun and clouds, along with scattered showers and thunderstorms, most active from about 1 until 9 p.m. Like recent days, the heavier storms will bring heavy rain and the threat of isolated flooding, and the high will be between 87 and 90 degrees for most places. The average high for Birmingham on July 22 is 91.
THE ALABAMA WEEKEND: An upper ridge will build into the region from the west, meaning increasing amounts of sun, higher heat levels and fewer afternoon thunderstorms. We expect a high between 89 and 92 degrees Saturday and Sunday, and the chance of any one spot getting wet both days is 15-25%. Humidity levels will remain high, which is what you expect here in late July.
NEXT WEEK: The ridge aloft will keep the weather hot and humid through the week with highs between 90 and 94 degrees. Days will be partly to mostly sunny with isolated or widely scattered showers or thunderstorms during the afternoon and evening hours. The chance of rain for any given location each day will be 20-30%.
TROPICS: A broad trough of low pressure associated with a dissipated frontal system over Alabama and Georgia is forecast to move off of the southeastern United States coastline on Friday. Environmental conditions are expected to be marginally conducive for some gradual development over the weekend and into early next week while the system meanders off the coasts of Georgia and eastern Florida. The chance of development over the next five days is 30%. The Gulf of Mexico and the rest of the Atlantic basin remain very quiet.
So far this season, there have been five named tropical systems in the Atlantic basin. The next names on this year’s list are Fred, Grace, Henri, Ida, Julian, Kate, Larry, Mindy, Nicholas, Odette, Peter, Rose, Sam, Teresa, Victor and Wanda.
ON THIS DATE IN 1993: The levee holding back the flooding Mississippi River at Kaskaskia, Illinois, ruptured, forcing the town’s people to flee on barges. The incident at Kaskaskia was the most dramatic event of the flood. At 9:48 a.m. the levee broke, leaving the people of Kaskaskia with no escape route other than two Army Corps of Engineers barges. By 2 p.m., the entire town was underwater.
