In my humble opinion, yesterday was the most beautiful and comfortable late June day I have ever seen in the Washington area. And that covers almost 40 years. We were on the very cool and dry side of a sprawling area of high pressure. On the west side of the system, it is not beautiful and comfortable. In fact, incredible heat is scorching parts of the Rockies and High Plains and that air is heading this way. Today will be comfortably warm because humidity levels will remain low. But beginning tomorrow and lasting through the weekend, temperatures and humidity levels will rise. It will become oppressively hot and humid on Friday, Saturday and Sunday. There will be a 30% chance of scattered afternoon thunderstorms during this upcoming stretch of high heat and humidity.
Slightly cooler air will return on Monday and I mean that literally. Highs will drop into the lower 90s.
