Snow & sleet totals this morning were trace to 0.5" over the viewing area.  Most of them were trace to 0.3".

However, a narrow corridor from Champaign & Vermilion counties in Illinois to Clinton, then Tipton to Grant, then Wells to Allen counties in Indiana saw up to 0.6" of snow.

Conditions will go downhill quickly from here on out this evening.

Note the snow/sleet line using Correlation Coefficient on radar.

It is mostly sleet in southern Tippecanoe, Clinton, Montgomery & Fountain counties with all snow northward.

Moderate snow & sleet will change to snow, sleet & freezing rain, then mostly light freezing rain & sleet tonight (expect in far northwest fringe where it may be all snow).

Temperatures will fall to the 23-27 range.

So, colder air bleeds in at the surface, but nose of warmer air aloft increases, resulting in icy mix, despite dropping surface temperatures.

We should go back to snow area-wide tomorrow morning with areas of snow through the day & into tomorrow night before tapering to just spotty snow showers.

Temperatures will run in the 27-31 range.

Winds will be gusty with gusts +30 mph at times now to tomorrow (from the northeast, then north).

3-6" northwest half & 1-3" southeast half (with much more in the way of sleet & freezing rain) are likely.

Looks like near 3" of snow with some ice around Greater Lafayette by Thursday night. 

I held off on expansion of 6-9" into Jasper & Newton after closely analyzing new data.

Isolated to spotty snow flurries/light snow showers are possible Friday, followed by a wave of snow showers Saturday (1" or less) as clipper moves through.

After 18-25 Friday morning, highs Friday should run 28-32.

Highs Saturday should run 29-33 after 18-22 in the morning.

If we can clear the skies, then we could randomly, suddenly drop to single digits.  Trend has been to keep it cloudy.  However, with th snow & ice pack, such a drop is possible.

If this occurs, this would be a near 60-degree drop in just a few days!

Some snow/icy mix to rain is possible Sunday-Sunday night, followed by a transition to some snow before ending by Monday.

Brief icy mix to rain is likely late Tuesday to Wednesday as temperature warm.

Icy mix/snow is possible next Friday as colder air comes in & system moves in from the southwest.
