Storm Team4 Forecast: Lovely start to week before storm chances move in

The useful part

Really nice Monday and Tuesday Dry through Wednesday Thursday looks stormy Weekend looks dry High pressure over the Great Lakes moves in our direction Monday and brings several very nice days for the last week of August. Monday night and Tuesday night will be open-window weather for many, as temperatures north and west of Dulles Airport fall into the 50s. Closer to the urban areas and Chesapeake Bay, overnight lows will drop into the low to mid-60s.

How it works

• There could be a few showers Thursday morning, but most of the rain will be in the form of thunderstorms Thursday afternoon and evening.
• The front will only slowly drift to our south on Friday, leaving some residual showers in Friday's forecast.

• Wednesday will see a gradual increase in clouds and humidity levels, as high head for the mid-80s.

What to take from it

As we head into the weekend and humidity levels remain elevated, there will be scattered storms each afternoon. Weekend rain chances are only around 20-30% for Saturday and 10-20% for Sunday.
