I think that timeframe is to watch for a pattern change. Most have that cold front changing the locked in pattern that we've had for the last month. Can see the cold air actually has a mechanism to finally make its way eastward.
We had all of our snow in a 2 week period that winter. Jan 1st-Mid January. 4 decent LES events in that two week period. Finished around 80" that year.
