Heating Up Again...and Keeping a Close Eye on the Tropics...

We enjoyed a rather pleasant day across central Virginia to start the new work week, with lots of sunshine and afternoon temperatures in the mid 80s. The temperature will start to climb, however, over the next 24 to 48 hours and the heat will be back in the Mid-Atlantic for a couple of days.

High pressure will move over us and then shift off the coast later Wednesday into Thursday, enabling temperatures to jump back into the 90s. Then the next front will slowly approach from the west and increase our rain chances later Thursday and especially Friday.

The start of the weekend could be rather interesting, as the tropics could get involved. As of late Monday night, a tropical wave is interacting with an upper low about 300 miles from the Leeward Islands. Conditions may become favorable for development with this system as it moves to the west-northwest. Some of our computer model data suggests this feature could have an impact over the Mid-Atlantic later Friday and Saturday, at the very least increasing the amount of moisture over the region. This is certainly something to keep a close eye on over the next few days, especially if you have weekend plans that take you to the coast.
