This is the coldest start to December in 8 years. We are now running as much as 2 degrees below normal in the viewing, despite the year seeing the annual mean temperature near normal due to an incredibly hot May & a hot summer to early Fall.
It is interesting to note that the 2005-10 December all started out cold to very cold, while 2012-17 Decembers seemed to all start out mild to very warm.
We also have tied for 10th coldest December 10 on record with a present high of just 25 degrees as the "Dirty High" keeps it cold & gray fogginess in places.
The depth & widespread nature of the freezing fog this morning along with a "Dirty High", whose sinking air has trapped the low clouds & fog near the ground, has kept it COLD today.
Additional patchy freezing fog is likely tonight, along with some black ice & frost. Watch for some slick spots!
Scattered rain/snow/sleet showers is likely Wednesday. It looks like the showers may begin as snow/sleet, then go to rain/snow, even just rain, then end as all scattered snow as temperatures fall.
So, after around 32 in the morning & a high of 41 around 1 p.m., we should drop to near 34 by 5 p.m.
Southwest winds at 10-20 mph will turn to northwest in the afternoon.
Any accumulations look very minor at less than 0.4".
Widespread rainfall will overspread the area Thursday. It may begin briefly as sleet/freezing rain with breezy conditions (east to southeast winds to 25 mph).
Rain will continue Thursday night & into Friday before ending as a period of wind-driven snow. Any accumulation looks minor at less than 1".
After a high of 41-46, temperatures will drop into the 30s. Winds may gust to 40 mph, especially as temperatures drop & snow falls in the p.m.
Total rainfall will run 0.80-1.25", causing the Wabash to rise to, even exceed, flood stage again.
Next weekend looks dry with highs around 40 & lows in the upper 20s with partly to mostly cloudy skies.
Snow showers are likely Monday with the potential of some minor accumulation of 1" or less & highs in the 30s.
Rain to snow is possible later next week with highs in the 30s & 40s.
Much colder will arrive after Christmas & especially around New Years.
