Storm Chances Increase Again Later This Week

The front that was responsible for bringing thunderstorms to our region on Sunday will cross the region throughout Monday.  While lingering shower and storm chances, especially to our south and east, will prevent a wholly nice day, the region will see its latest streak of 90 degree weather come to a thankful end.  High pressure builds for Tuesday and most of Wednesday, dropping dew points to the much more tolerable 50s and lower 60s, making Tuesday and Wednesday the "nicest" weather days of the coming week.

However, as we all know from past August weather, low humidity in August is a fleeting proposition.  

As the high nudges off the coast later Wednesday, we'll see an increase in dew points and a slow, gradual increase in thunderstorm chances.  Wednesday could see a stray pop-up storm to our west.  Thursday could bring a storm or two around, but most of the region and most of the day will be dry.   Friday brings the most widespread thunderstorm chances to the region as a low pressure center approaches from the west.   That storm chance could carry into Saturday, but the weekend, at least from this far out, does not look like a total washout.  

As far as threats from the tropics are concerned, there are two storms out there — Ernesto, tracking towards the Yucatan and eventually towards either Northeast Mexico or Texas, and Florence, spinning in the Eastern Atlantic and probably weakening later this week.  Neither Ernesto nor Florence are a direct threat to the East Coast.
