Arctic Blast………Data Favors More Snow Than Mix/Rain Thursday-FridayJanuary 19th, 2013 at 6:29 pm by Chad Evans under Chad's WLFI Weather Blog
Still looks very cold Sunday-Wednesday with coldest weather Tuesday with a high near 12 & low near 1. If there was a nice snowpack from here to Minnesota (where there is none to very little), I am convinced this cold wave would drop our overnight lows to -11 with single-digit daytime highs.
Over the past several days there has been a clear signal of a warm frontal passage with light freezing rain & sleet Thursday p.m., changing to rain Thursday night as temperatures rise to 36. After a peak of 37 early Friday morning & an end to the rain, temperatures looked to fall Friday afternoon.
New data & soundings favors more of a snow system than mix to rain. The column of the lower atmosphere & the surface certainly looks colder with a more southerly trend with this system.
So, I like a snow/wintry mix wording to the forecast, which may end up as all snow if current trends follow. We will watch, as this would be an accumulating snowfall. In my winter forecast, I found a strong response of a 4-6″ snow with some mix in the south in latter January.
Otherwise, in terms of snow for the other days, a clipper late Sunday-early Monday may bring a coating in places & another one is possible Tuesday with a few lake effect snow showers in our northeast in-between on Monday.
