A rapid warmup will begin today as Gulf moisture surges northward. Highs today will range from the middle 80s in the northeast to the middle and upper 90s in the west. South winds will increase between 15 and 25 mph with some gusts around 30 mph, especially this afternoon.
The heat will continue on Friday with temperatures warming into the 90s. A few spots out west may even reach the century mark. It will also be humid which will make it feel even hotter. A south to southwest wind will prevail between 10 and 20 mph with occasional higher gusts.
The chances for thunderstorms this Saturday will depend on whether the cap weakens enough to allow storms to develop. The cap is a layer of warm air that is located 1-2 miles above the surface that can suppress storm development. If storms are able to develop Saturday, they will likely be severe and capable of producing large hail and damaging winds.
Warm temperatures and humid conditions will come together starting Friday leading to heat index values exceeding the 100 degree mark in many locations. Given the relatively cool days we had early this week, this will be a stark change coming for Friday and continue Saturday. Make sure to drink plenty of water and never leave children or pets alone in vehicles!
The heat will continue Saturday with heat index values exceeding 100 degrees for most locations. This will be the second day in a row with hot index values and precautions should be taken if heading outdoors. Make sure to drink plenty of water and do not leave children or pets unattended in vehicles.
A cold front will move slowly south across the region Saturday night through Sunday and result in scattered showers and thunderstorms. Since the storms will be scattered in coverage, many areas may stay dry or only see a little rain. Precipitation chances right now are in the 30 to 50 percent range for Saturday night and Sunday, but check back for updates since the forecast will possibly change as new weather data becomes available.
