James Spann: Only isolated showers, storms for Alabama; hot through the weekend

RADAR CHECK: We have a few small, isolated, short-lived showers across Alabama this afternoon, but most communities are simply hot and dry, with temperatures in the 90s. Any showers this evening will end quickly after sunset, and tonight will be mostly fair with a low in the 70s.A strong upper high will continue to build into the Deep South through the rest of the week, meaning our weather won’t change much. Expect partly to mostly sunny days, fair nights and very few afternoon showers or storms. The warm air aloft and sinking air motion associated with the ridge will squash most developing showers; odds of any one neighborhood seeing rain each day through Friday are 10-20%. Highs will be in the mid to upper 90s and lows in the 70s, classic “dog day” weather.
We might see a slight uptick in the number of scattered afternoon storms over the weekend, but the overall weather won’t change much. The probability of one location seeing rain both days is 25-35%. Highs remain in the 90s.
NEXT WEEK: We won’t see much change Monday through Wednesday, but there is evidence the ridge could weaken over the latter half of the week, with lower heat levels and an increase in the number of scattered showers and thunderstorms.TROPICS: A tropical wave is in the eastern Atlantic, a couple of hundred miles southwest of the Cabo Verde Islands. Conditions are expected to be favorable for gradual development of this system later this week and into the weekend while it moves westward to west-northwestward over the tropical Atlantic.
The rest of the Atlantic basin, including the Gulf of Mexico, remains very quiet. No systems will threaten the U.S. for at least the next seven days.
ON THIS DATE IN 1890: During the morning, an estimated F3 tornado went through the southern part of Lawrence, Massachusetts. It left 500 people homeless as it destroyed 35 homes and damaged 60 others.
ON THIS DATE IN 1943: The “surprise hurricane of 1943” made landfall on the Bolivar Peninsula (Texas, near Galveston), bringing winds of 96 mph to an unprepared population. It was estimated that 95% of the buildings in Galveston and Texas City sustained damage.
ON THIS DATE IN 1979: Tropical Storm Claudette stalled over Alvin, Texas, inundating the town with 45 inches of rain in 42 hours. The total included 43 inches in 24 hours, which was the maximum 24-hour rainfall in American history at the time. Claudette would be followed in 1979 by David and Frederic, two major hurricanes.
