Steamy pattern through the weekend...

We enjoyed some delightful weather over the past weekend into the early portion of this week, with low dew points in the upper 40s and low 50s (meaning low humidity!). At this time of the year, that is absolutely terrific in Central Virginia and you knew it had to change. Dew points have been on the rise the last couple of days and we're in for some sticky conditions this weekend into early next week.

While we've seen a few showers and even thunderstorms scattered about the state, there hasn't been much rain over the last week (and the last month for that matter). If you're waiting for some rain, our chances will be going up over the weekend. We may get to see a few storms pop up before then, but a front arriving from the Midwest will be the main trigger for some widespread showers and thunderstorms. The period I'm focusing attention on is Sunday through Tuesday. Hopefully some beneficial rain will put a dent in the drought conditions now affecting parts of Virginia.

Looking ahead to next week...

This front will likely stall near or over us, leading to a continued threat for scattered showers and thunderstorms through at least Tuesday. There are signs that the high pressure ridge now over the Rockies and Plains (bringing days on end of triple-digit heat to places like Montana and the Dakotas) will begin to shift a bit to the east. This could lead to a drier but hotter spell heading into the first weekend of August.

The tropics...

Still nothing doing in the tropics! While a few clusters of thunderstorms have popped up over the Gulf of Mexico, nothing has been able to organize and it remains pretty quiet over the open Atlantic. It will be interesting to see if there is any development over the next couple of weeks, as we head into August. Remember the peak of hurricane season is in early to mid-September.
