The region will get an early taste of summer this week, with hot afternoon temperatures and warm evenings through Wednesday, according to the National Weather Service.
Forecasters have issued a heat advisory from noon today until 9 p.m. Wednesday, predicting daytime high temperatures of 91 to 97 degrees, with the hottest temperatures in the urban areas in the late afternoon and early evening.
Evening isn’t expected to provide fast relief, with slow cooling and overnight lows of 60 to 67 degrees tonight and the coolest temperatures coming around 5 a.m. Wednesday.
Forecasters warmed that hot temperatures and limited overnight relief will increase the chance for heat related illnesses, especially for those sensitive to heat. People most vulnerable include those who spend a lot of time outdoors, those without air conditioning, young children and the elderly. Heat stress is also possible for livestock and outdoor pets.
The reason for the mini heat wave is a high pressure system aloft and a thermal trough that is expected to hold position until late Wednesday, when changing conditions will bring an onshore flow of cooler air into the region. Temperatures will be seasonal on Thursday, with warmer weather expected this weekend.
