James Spann: Showers remain hard to find in Alabama; expect cooler nights later this week

RADAR CHECK: We have a clean sweep on radar at mid-afternoon … Alabama is warm and dry with temperatures in the 80s. Still some risk of a small, isolated shower this evening, otherwise tonight will be mostly fair with a low in the 60s.

Very warm and mostly dry weather continues across Alabama through Wednesday. Highs in the 85–90-degree range; any afternoon showers will be very isolated. Heat levels will fall later in the week thanks to a northerly flow; by Friday morning many North Alabama communities will drop into the 50s, with highs around 80 degrees. South Alabama will still see highs in the mid 80s.

THE ALABAMA WEEKEND: For most of Alabama, showers will be few and far between Saturday and Sunday with highs in the low to mid 80s. However, a weak surface trough in the northern Gulf could bring some rain to the coast at times. Not a wash-out at all, but a few periods of rain are possible both days across southern Mobile and Baldwin counties.

Global models do show some increase in moisture early next week with a risk of showers Monday and Tuesday, but still nothing especially heavy or widespread. See the video briefing for maps, graphics and more details.

TROPICS: Tropical Storm Imelda, with winds of 60 mph, is about 220 miles east/southeast of Cape Canaveral, Florida this afternoon. It is moving to the north at 9 mph. Imelda is forecast to become a hurricane tomorrow; it will take a sharp turn to the east and will remain well off the Southeast U.S. coast. It could impact Bermuda Wednesday night, however.

Hurricane Humberto, with winds of 140 mph, is about 320 miles southwest of Bermuda… moving to the north/northwest at 13 mph. Humberto will pass well to the west of Bermuda tomorrow as it heads out into the North Atlantic. Still, Bermuda is under a tropical storm warning due to the size of the wind field.

The rest of the Atlantic basin is calm, and no tropical storms or hurricanes are expected across the Gulf for at least the next 7-10 days.

ON THIS DATE IN 1927: An outbreak of tornadoes from Oklahoma to Indiana caused 81 deaths and $25 million in damage. A tornado, possibly two tornadoes, cut an eight-mile-long path across St Louis, Missouri to Granite City, Illinois, killing 79 persons.

ON THIS DATE IN 1959: Category four Hurricane Gracie made landfall over St. Helena Sound near the south end of Edisto Island in South Carolina. Much of the destruction related with Gracie was centered on Beaufort.
