Cold Air Returning; What About February Forecast?

The cold air, as indicated by the following NOAA forecast map for Tuesday’s high temperatures, is beginning to make inroads back into the northern part of the United States. The question many of us have is whether it will return to the intensely cold pattern of December into the first half of January, or whether this new shot of cold air will be a glancing blow in our march toward spring.

Cold to Return for East and South 

According to the coupled forecast system (NOAA long-range computer forecast model), it will be somewhere in between–cold in the South and East, but the cold will not be as extensive across the country or as intense. (Note: The February 2010 forecast is indicated on the map in the upper-left in the following image.)

  1. good morning; cold air returns; and northeast; will brace for a question mark? for the weekend; could be very white…

    • Hi Frank! it’s certainly something to watch. The GFS is often too far to the south with its initial forecasts…

  2. Yes, 65F in the DC area around mid-day. A convective rain shower with rumbles of thunder just moved through the area.

    Snow forecast for the end of the week. Get ready for the “this weather is crazy!” crowd.

    • You’re right about that, Steve–they’ll be out in force soon.
