FIRST ALERT WEATHER: Heat index expected to be around 103°

(WAFF) - Heat continues to be the big story especially now that our afternoon storm chances are even lower than they were earlier this week. Highs today will be in the mid/the upper 90s with a heat index around 103°.

Thursday and Friday could both be First Alert Weather Days with heat indices climbing to 105° or above in many spots. Make sure you're staying hydrated if you'll be working outside.

Try to take some breaks in the shade or air conditioning if possible. Pets also need a shady place to rest and cool water to drink if they'll be staying outside in this heat.

We're starting this morning with readings in the low-to-mid 70s. A few pockets of fog are possible, but in general, skies are mainly clear.  We'll warm up quickly with temperatures into the 90s by the late morning.

A few stray storms may pop up with the afternoon heat, but most will remain dry. Temperatures will be slow to cool this evening, and the heat index should stay at 90° or above through around 9 p.m. Lows tonight will fall into the lower 70s under mainly clear skies.

Dangerous heat sets into the Valley for the end of the work week. Highs Thursday and Friday should be close to 100° with a heat index of 105°+.

Like today, the storm chance will be very low so most won't receive any relief from the heat in the form of afternoon rain. We start the transition back to more normal temperatures over the weekend.

It will still be hot Sat/Sun, but not as oppressively hot as the close of the work week. Highs should still be in the mid-to-upper 90s with a heat index as high as 103°. Isolated afternoon storms will be possible.  For the start of the next work week, look for highs in the mid-90s with a better chance for afternoon storms.
