Another Arctic Blast on the way but slightly less worse. A warming trend is on the way with January ending “blow torch” — ?

Temperature anomaly over the next 7-days shows the quick erosion of the Arctic air mass by warmer Pacific flow as well as Gulf of Mexico moisture. Definitely a much milder pattern compared to the brutal cold we’ve experienced over the past several days.

A strong ridge will build over the Great Lakes into the Mid-Atlantic by early next week intensified by southerly flow with plenty of moisture coming out of the Gulf of Mexico.

There is a decent chance for light accumulation snow again for Washington D.C. to NYC on Friday, but hopefully nothing too impactful for travel. This is shaping up to be a 1”-3” or 2”-4” type system as it moves quickly off the coast before being able to intensify.

The serious freezing rain accumulation threat [> 0.50”] in Portland, Oregon materialized this evening with Ice Storm Warnings. Colder air at the surface in the 20s is being overridden by much warmer Pacific moisture = freezing rain once it reaches the surface. Hopefully there is no significant damage or power outages.

NWS even has an area of 1.2” of ice accumulation.
