Heat Safety Tips

[12:30 P.M. Monday, July 27] For this afternoon, the very humid and hot air mass in place will likely allow for at least isolated storms. The areas with a little higher confidence in this are our southern and eastern areas as shown on this map. There will be many locations though that remain dry (and hot!). Some severe storms are possible, with isolated damaging winds being the main threat.

The heat and oppressive humidity will continue through today with peak heat indices between 105-115 degrees expected! An Extreme Heat Warning is in effect area-wide. Make sure to limit your time outside today!

Here is the latest hourly heat index forecast for today (7/27).

Isolated to scattered thunderstorms are possible today, mainly during the afternoon and evening. Confidence remains low on the coverage of storms; however, if storms develop they could quickly become severe with damaging winds as the primary threat.

With humid conditions once again in the forecast, please remember to practice heat safety tomorrow and Monday! If outside, drink plenty of water and take frequent breaks in the shade.
