12.30.20 Weather Bulletin: Timing Out Period Of Wet Snow By Evening; Icy Glaze To Open New Year’s Day…

Rain Ends As Wet Snow This Evening…A cold rain will continue to overspread central Indiana this morning. A cold front will slip south across the state through the afternoon and temperatures will fall into the 30s prior to sunset across most of the region. One final wave of moisture will push northeast across the area as temperatures fall into the low and mid 30s leading to a brief period of wet snow between 6p and 10p (northeast to southwest). We’re likely only looking at a window of 1-2 hours of snow at any one location, but it could fall moderate to heavy during that brief window and accumulate between a dusting and 1.5″. We’ll keep an eye on model trends through the day.

New Year’s Eve will feature dry, but gloomy and cold conditions. Look for overcast skies and highs struggling to make it to freezing.

Our second area of low pressure will lift north from the northwestern Gulf Coast into the Midwest Friday and Saturday. This will help widespread precipitation overspread the Hoosier state New Year’s Day (before sunrise for most). With cold air locked in at the surface, precipitation at the onset, continuing for a few hours north of a line from Terre Haute, Bloomington, and Cincinnati, will fall as freezing rain. If traveling early, we’d recommend caution as a light icy glaze (less than .10″ for most) is a good bet. Eventually warmer air will win out, switching things to a “plain ole rain” late morning into the afternoon.

Lingering showers will end Saturday as a trailing piece of upper level energy moves east across the Ohio Valley. Dry skies will return as we open up the new work week.
