Discussion
Canadian high pressure will take control of the weather today leading to the coolest day so far this fall season and the possibility of the first frost late tonight in many suburban locations. Radiational cooling conditions will be quite good in the overnight hours as high pressure parks overhead and generates clear skies, light winds, and overnight temperatures down in the 30’s in some areas.
Looking ahead to the weekend, strong low pressure system will form off the Southeast US coastline and produce heavy rainfall and strong winds for the coastal Carolinas including - once again - the Outer Banks of North Carolina. This strong coastal storm system is then likely to push northward to or just off the Mid-Atlantic coastline by later in the weekend...likely resulting in an impactful rain and wind event for the Mid-Atlantic region from late Saturday night-to-Monday.
