The heat and humidity are both on high this week. It looks to me like we will have 90-degree days today and tomorrow, before temperatures start paring back a little, due to a bit more cloud cover and an increased chance for showers.

The National Weather Service has issued heat advisories for much of the state, in effect through 8 p.m. Tuesday.

On Wednesday and Thursday, you'll see a better chance for a pop-up thunderstorm, although there will also be sunshine — so if you are on vacation, expect some good beach time.

The humidity is really what's going to be noticeable. Dew points remain around 70 degrees the next couple of days, and that keeps that summertime feeling really strong.

When you have a lot of moisture in the air, it's difficult for it to cool off at night. In this pattern, after the daily high reaches 90 or higher around 4 p.m, it will remain in the 80s past sunset. The low temperature you see in the upper 60s to near 70 doesn't occur until 4 or 5 a.m., so it can be difficult to sleep.

A cold front will approach the region Wednesday. This brings a better chance for showers and storms, but they won’t be widespread. If the front moves quickly, Thursday will be drier and not as hot. Humidity will also drop. I think it will become hot and humid again by the end of the weekend.
