Cold Unleashes on the East Coast into early February


We have been enjoying milder temperatures over the last week or so, and will continue to do so up until the 30th. A cold front will push though on or around the 30th, and a weak wave of low pressure will form along the front. However, precipitation is looking like rain at this point. But the cold air will certainly follow behind the departing storm system. Lows will dip into the upper 10s North and low 20s across the South. Temperature departures from normal are shown for Jan 30 on the GEFS ensembles.

Then we have the potential for a major storm system around the 3rd. This is yet another Arctic front, and a much stronger Arctic front. This front has the potential to stall, and develop a wave of low pressure off the coast. This low also has a higher chance of developing than the one on the 30th. If it does, then SE VA and the Mid Atlantic can expect some snow. Philadelphia and southeast PA is included. These locations have the highest chances of seeing snow. How much or for what location is not clear. After this storm departs, the deep freeze returns. Temperatures will be below normal, and in some locations, well below normal. We could once again reach the 0s and 10s in the South, and even -0s up North.

The GEFS has brutal cold for many people as shown above on Feb 4th. The light purple over Canada is likely subzero temperatures.

Get the firewood now and make sure you have a heat source available for the 30th through the first week of February. Also, pipes are in danger of bursting once again so make sure you leave faucets dripping when the cold hits.
