Snow Melt then Snow Fall

Good Morning. 
​
Well, the January thaw is underway in the eastern USA. It is common and occurs most every year. Now ours has not been exceptionally warm up to today. I believe it will not get all that warm until Wed of next week.
Three storms could impact our weather in the coming week as seen left to right above. 

• First storm impacts us Monday as it moves through the Great Lakes, and east through eastern Canada. It will drag a cold front through our area Monday.
• Second storm will be the big one. It will produce a major snowstorm/blizzard for the central plains and Rockies. This system will also move to the Great Lakes and off into Canada. This means we will be on the warm side. A large push of warm air will occur. Pushing temps into the 50s on Wed.
• Third storm is more questionable. This is likely to develop on Friday along the cold front that moves through our area on Wed. The question is whether or not it will be close to the coast or off the coast. The difference is only several inches of snow vs. flurries.

The largest battle of the forecast this week is for Sun and Mon.  And it deals with temperatures. Right now the models could not be any further apart than they are.

• Short term American (NAM) is showing our temps stay around 40 for high temps as cool air gets stuck at the surface and warm air overrides the more dense cool air creating a very stable atmosphere.  This is like cold air damming, just not classic.
• Short term Canadian (RGEM) is showing our temps stay around 50 for high temps as the cool air gets removed and warm air takes over.
