If we can't get measurable snow before January 1, October-April 2020-21 snow season would rank as having one of the latest first measurable snows on record. Even the warmest winter of 1931-32 record saw 4.0" of snow on November 27 at Greater Lafayette! Only 0.5" fell for the December-January-February period, however! The coldest air of the snow season (October-April) was in March. It was also the snowiest month of the 1931-32 snow season.
The latest measurable first snow on record was January 5, 1972 with 2.0" & the second latest was January 2, 1914 with 0.5". Both November-December 1971 & 1913 only saw Trace amounts.
Recently, 1994-1995 had an exceptionally late first measurable snow with a mere 0.1" on January 1, but 1.0" fell January 6.
Trend now to January 1 overall is warmer than normal.
Trend now to January 1 is wetter than normal.
Looks like all rain late next Saturday to next Sunday & all rain Christmas Eve-Day with warm weather.
Colder than normal weather & above normal precipitation by early January signals snow & ice risk during that time. This colder than normal pattern will likely not last long, but we could squeeze out a couple of winter weather episodes out of it with accumulating snow &/or snow/ice.
Colder than normal early January:
Above normal precipitation:
However, can we get something before that which would prevent 2020 from having one of the latest measurable snowfalls on record for Greater Lafayette & a good chunk of the viewing area? Could this occur even in the milder, wetter regime?
It appears that the best potential of some minor accumulating snowfall now to January is actually shaping up only for Wednesday morning of this week.
There are signs of a southern system tracking far enough north with enough cold air for the potential of some minor snowfall. We shall see. It is not a certaintly. We have 20% of snow Wednesday morning in the 7-day right now.
Being Wednesday morning it would be of pretty short duration.
Otherwise it is mild, wet weather & any snow we can accumulate Wednesday morning will not last long.
