Rain turns to accumulating snow Thursday night and watching a potentially bigger storm early next week

At least we managed some outstanding corn-days ahead of the rain Sunday night. It was the 2nd in a series of rain events associated by this +EPO driven weather pattern. There's a a third event that will start as some rain and then the news gets better, at least if you remain a fan of seeing more winter weather after St Patrick's Day. 

The weather this Tuesday and Wednesday can easily be compared to what we saw this past Friday and Saturday and in the same order. Sub-freezing temperatures in the early morning will be quickly erased by strong doses of March sunshine. Temperatures on Tuesday will be up close to 50 at the base and a bit cooler well up on the mountain followed by readings near 60 at the base Wednesday. Winds should remain light until Wednesday afternoon when southerly winds are expected to increase and become gusty. 

We can expect another mild day Thursday though clouds will be on the increase and this alone is expected to keep temperatures a little cooler in spite of a milder morning. Precipitation is expected to hold off until evening and yet again, we are expected to see rain at least at the start. I am very encouraged by recent data from the Euro, which is showing a new area of low pressure near the Connecticut coast quickly becoming the dominant part of this weather feature. If this happens as forecast, we should see rain turn to some significant snow Thursday night and accumulate several inches by Friday morning. This is an excellent way to greet what we expect to be a new weather pattern featuring a much friendlier jet stream in the Pacific. I'll have more confidence in an accumulation prediction in a day or two, but my early call right now would be 4-8 by the start of the ski day Friday. 

We should see clouds and snow showers break for some sunshine later Friday and most of the mountain should stay sub-freezing while valley areas creep above freezing by a few degrees. Saturday appears to be a more typical March day with chilly temperatures in the morning giving way to near 40-degree afternoon warmth. A stronger dose of late March arctic chill is expected to bring temperatures below normal for Sunday out ahead of what could be a very interesting few days. 

I think this friendlier early spring weather pattern should persist into at least early April and the best end result of it all could come early next week. The euro ensembles are showing a strong storm signal with a fresh supply of cold air in place. Good support mechanisms in the jet stream both up and downstream and I think its just a question of what kind of storm we can churn up, specifically the intensity and evolution. By my count, we remain under 10 inches of snow for the month of March and this is kind of storm that could triple that very easily so its worth watching in the Monday, March 24th to Wednesday March 26th time frame.
