WEATHER BLOG: Cold Thursday
There will be an extra bite in the air throughout the day thanks to a northerly breeze.
A large area of high pressure positioned over eastern Canada Thursday morning will move into southern New England by the afternoon. Clouds will move up from the south as a storm system develops in the Southeast.
With a flow out of the north and northeast, high temperatures will wind up about 15 degrees or so below average for this time of year (which is now 50).
As that high pressure area slides eastward into the Atlantic on Friday morning, the storm system in the Southeast will be emerging off of the Carolina Coast. The system will then track northeastward off the coast during the day Friday.
Some rain from this system will impact areas south and east of Baltimore, and there may even be a brief shower or period of rain that makes it back to the city Friday afternoon or evening.
The best opportunity for rain, though, will be across the Delmarva Peninsula.
