Warmer temperatures and higher humidity levels moved into the area on Saturday, and this general pattern will continue a few more days. Highs away from the coast will range from the mid 80s to around 90° through Tuesday. The normal high for this time of year is in the upper 70s, and the normal low is in the mid 50s.
Widely scattered storms will be around through Tuesday as well. Higher chances for rain exist for areas well north and northwest of Richmond. Lower chances for rain will be found across extreme southeastern Virginia.
Due to the high humidity, and storm that does develop will produce heavy, localized rainfall. Isolated storms could get strong with some hail or stronger wind gusts.
A cold front will slip southward on Monday. This will cause a better chance of a few storms, and it will bring some cooler, less humid air to eastern and northeastern Virginia. This front will lift back northward on Tuesday.
A stronger cold front will move in from the west on Tuesday. Scattered storms in the afternoon and evening could be strong to severe in a few locations.
Behind the front, cooler and less humid air will settle in for the middle and end of the week.
As of now, it looks like the holiday weekend will have highs in the low to mid 80s, and any chance of rain would be fairly low.
