The big weather story over the coming days will be the bitterly cold air temperatures, even colder wind chills, icy roads, and another snow event.

This winter actually feels like winter, for once.

The rest of today into Sunday night will deliver a mix of sun and clouds.  More clouds on Sunday.  A few snow flurries, but nothing of consequence.

A stronger system will arrive on Monday and Monday night.  This system will spread a band of snow from north to south across our region.

Gusty winds will accompany the cold front.  Bitterly cold air, as well.

Snow totals of one to two inches will likely occur with this event.  A few higher totals possible.  Either way, this will only compound the icy road conditions.

Blowing snow is also possible.

See the snow probability maps further down in this winter weather update.

Here is the future-cast radar from the NAM guidance.  This is for Monday into Monday night.  Blue would be snow.  Green would be rain.  There remains some questions about the possibility of a brief period of rain ahead of the snow showers.   This would be more likely near the Missouri and Arkansas border and the Kentucky and Tennessee border.

Plan on some school closings Tuesday.

Temperatures will drop into the single digits Sunday morning, Tuesday morning, Wednesday morning, and perhaps Thursday morning.  Wind chills of -15 to 10 above will be possible over the coming days.  The coldest wind chills may end up being tonight and Sunday morning, Monday night and Tuesday morning, and Tuesday night and Wednesday morning.

Sunday morning lows.  Some areas will be colder than this.  It is not out of the question that areas with deeper snow end up ranging from -3 to 3 above.

Monday and Monday evening

Currently this appears to be a late morning and afternoon event.  It will move from north to south.  Arriving first in Mt Vernon and ending first in Mt Vernon.  Arriving last along the Kentucky/Tennessee border.

This will need updating.  These are my best forecast thoughts, for the time being
.

Southern Illinois

Southeast Missouri zone one and zone two

Western Kentucky zone one and zone two

Northwest Tennessee

.
Here is the EC model guidance snow forecast.  This is for the Monday event.
.

.
Here is the NAM model guidance.  Some differences.  Still time for adjustments.

These are the snow forecast totals from the NAM for Monday and Monday evening.

Here is an interactive map of the snow totals from the last two days.
