/cloudfront-us-east-1.images.arcpublishing.com/gray/3DDNICW2CNDJHKOO223XRL3VBE.png)
Increasing moisture moving inland from the Gulf of Mexico will lead to somewhat better rain chances today. Gulf moisture will keep summer-like humidity in place through the workweek.
/cloudfront-us-east-1.images.arcpublishing.com/gray/4HKXW6PKKFCZBNXMRWEXDW53GA.png)
After a mostly-dry Memorial Day weekend, we bring scattered t-showers into the picture for Tuesday. After that, however, it’s a drier pattern.
/cloudfront-us-east-1.images.arcpublishing.com/gray/F6WSVPGN2ZAQJDP3LLKF6BZP74.png)

/cloudfront-us-east-1.images.arcpublishing.com/gray/CIG5UVVKWFDX7OCGEWPEPFCA3A.png)
The high pressure lid on the atmosphere that has kept us dry for the last few days will weaken over the weekend, allowing for scattered showers and storms.

Still dealing with warmer-than-normal days that will continue through the weekend and into next week. Scattered rains return to the forecast for Thursday through Sunday.

/cloudfront-us-east-1.images.arcpublishing.com/gray/2LHUYWRCGBFMVPUKR5STPUX4DY.png)
Temperatures come close to 90° Wednesday afternoon and increasing humidity levels will certainly make it feel like the low 90°s, even if the air temperature doesn’t quite make it.
/cloudfront-us-east-1.images.arcpublishing.com/gray/VXLS4W7ERZFUVGQQCQKVZNCZGI.png)
Spring is apparently taking a hiatus as summer has arrived early, and the heat and humidity are going to be the main weather story for the rest of this week and into next week as well.
