Discussion
Tropical Storm Michael is now headed away from the east coast and out into the open Atlantic and a new air mass will flood the Mid-Atlantic region today riding in on stiff northwest winds. This new air mass will be much cooler and less humid than recent days and overnight lows in the 40’s will take place for the first time this season. After a dry day today, there will be a weak disturbance that can set off a few showers late tonight and early Saturday before mainly dry and cool weather returns for Sunday.
