Heat Advisory issued for Wednesday; HOT temps with scattered thunderstorms
For our Tuesday night into Wednesday, we're working on some monsoonal moisture working into the region from the south. We'll look for increasing clouds overnight into early Wednesday. We have a chance of thunderstorms working in for Wednesday morning and the afternoon. Along with the moisture, we'll look for hot temperatures well into the 90's. With the added moisture to the air, the heat index will also rise through the day. The National Weather Service has issued a Heat Advisory for Wednesday. They issue Heat Advisories, based on how unusual the heat is, time of year (early season vs. deep summer heat), overnight temp recovery, duration of the heat event, and CDC heat health threshold.
