Very hot temperature are expected again across west Alabama where a heat advisory remains in effect until 9PM Sunday. The counties under the advisory include Lamar, Fayette, Pickens, Tuscaloosa, Sumter, Greene, Hale, Perry, Bibb and Chilton counties.
Temperatures will range from 93 to 97 degrees across the advised area. Higher humidity will allow feels like temperatures to range from 102 to 108 degrees. Hot and humid conditions will elevate the risk of heat stress and heat related illnesses such as heat exhaustion or heat stroke.
A heat advisory means that a period of hot temperatures is expected. Take extra precautions if you work outside or spend time out there. When possible, reschedule strenuous activities to either the early morning or evening. Know the signs and symptoms of heat illnesses. Be sure to wear light weight and loose fitting clothing when possible and drink plenty of water.
Heat relief is on the way in the form of a backdoor cold front! The front will be arriving from an atypical direction but will do what fronts do and that is create lift and bring cooler and drier air. Showers and storms will develop during the late morning hours and especially during the afternoon on Sunday, first across northeast Alabama and then southward with time. The most organized threat sets up to the east of I-65 and a lower chance for rain on Sunday to the west of I-65. An isolated severe storm can't be ruled out with damaging wind gusts being the primary threat. Showers and storms will be possible again on Monday as the front continues to push westward with time. The best chance on Monday sets up to the west of I-65.
By Tuesday, you'll feel a significant difference in the air mass. Dew points which are in the 70s will fall into the 50s by Tuesday and temperatures will not be nearly as excessive with highs near 90 degrees.
Have a great rest of the weekend!
