CONDITIONS AT 11:30 AM: We are really starting to see some scattered showers and thunderstorms form along the I-20 corridor east of Birmingham to the AL/GA state line, with a few down in the southeastern parts of the area as well. Nearly the rest of the area is rain free. Temperatures are ranging in the lower 80s to the lower 90s across the area. Birmingham was at 88 degrees while several locations were tied at 90 degrees at the hot spots. The cool spot was Haleyville at 82 degrees.
WEATHER FOR THE REST OF YOUR THURSDAY: The latest HRRR model solution for the rest of today through the late night and ends at 1:00 am Thursday is hinting at a line of storms moving eastward through much of Mississippi but falling apart as it crosses the state line around the 5pm-7pm time frame with only a few scattered storms affecting the northwestern parts of the state around midnight. At this point of the day, there is no line of storms, so maybe this run is out to lunch. We’ll keep a watch on it. At this point, we can expect scattered showers and thunderstorms across the area with the higher chances being north of a line from Fayette to Clanton to Auburn. Afternoon highs will be in the lower to mid-90s across much of the area with upper 90s possible in the southeastern corner of the area. Heat indices will top out in the 98-104 degree range.
For tonight and through the overnight hours, much of the activity will diminish after sunset but a few lingering showers and storms could persist for a few hours longer over the east and northeastern parts of the area, especially east of I-65 and north of I-85. Lows will be in the lower to mid-70s.
HEAT ADVISORY UNTIL 7:00 PM FOR PARTS OF NORTH ALABAMA: The western half of North Alabama is under a heat advisory until 7:00 pm this evening as the combination of high temperatures and increased humidity levels will result in dangerous heat levels this afternoon. Heat indices of up to 106 due to temperatures in the lower 90s, and dewpoints in the mid-70s. Counties in the advisory are Colbert, Franklin, Lauderdale, Lawrence, Limestone, Madison, and Morgan.
INCREASED RISK OF SCATTERED STORMS ON FRIDAY: With a trough over the Atlantic Coast and the ridge flattening out, we’ll continue to have hot and humid conditions on Friday. A developing surface low will be along the Alabama Gulf Coast and the western parts of the Florida Panhandle which will send more moisture and lift in our direction to allow for the development of scattered to numerous showers and thunderstorms across much of the area. The highest risk of storms will be south of the I-59 corridor, while there will still be a good chance of scattered showers north of that. Highs will be in the lower 90s across the area. Much of the activity will occur with the main heating of the day, but some showers and storms could occur during the morning and into the late night and overnight hours. Don’t expect much change at all for the weekend at this point.
