Back Door Cold Front Brings Slightly Cooler Weather


A warm front lifted north of the area yesterday bringing the warmest temperatures the peninsula has seen in over 7 months. Salisbury reached 87 degrees. The last time that occurred was October 7, 2013.

Well, last night that same front moved back south through the region as a back door cold front. So what is a back door cold front and why do we call it that?

A backdoor cold front is simply a cold front that moves in from a direction it normally doesn't move in from. It essentially comes in through the "back door." A typical cold front moves in from the west or northwest and turns our winds out of that same direction. A back door cold front moves in from the opposite direction. It moves in from the east or northeast, usually due to the circulation around a high pressure system helping to push it that way. The winds than shift out of the direction it came from.

This morning (Friday May 9th) the back door cold front is south and west of the region and our winds are currently out of the east, which is the direction from where the front came from. The weather is a bit cooler and cloudier this morning because the winds are coming off the cool ocean waters, which is also helping in the development of clouds and fog. The front is expected to lift back north as a warm front later today and start to increase our temperatures and humidity once again. Our winds will shift out of the south and southwest which is the direction from where the warm front will come from.

Hopefully you'll enjoy the summer time heat expected over the next several days.
