Tuesday night through Saturday: Widespread snow or freezing rain is unlikely.  A few flurries are possible tonight (TUE night) across the Missouri Bootheel and western Tennessee.

Saturday night through Monday:  I am monitoring a storm system that could bring a wintry mix changing to rain to the region late Saturday night into Sunday night.  Temperatures may warm enough for rain.  Too early for certainties.

Bitterly cold air will continue.  Additional power outages are likely along with busted water pipes.

Here are the low temperatures since Saturday night (here at my place in Massac County)

Saturday   11°

Sunday   8°

Monday  1°

Tuesday  -3°

You can expect single digit readings to lower teens tonight into Friday night.

Low temperature maps

Tonight

The GFS shows temperatures in the low to mid teens.  I think it may be too warm.  I would shave a few degrees off these numbers.

Wednesday night
.

.

.A few weak disturbances will pass through the area over the coming days.  Flurries can’t be ruled out.  Accumulating snow appears unlikely through Saturday afternoon.

Somewhat warmer air (use that word loosely) arrives over the weekend.  This warmer air will be key to precipitation chances as a disturbance moves into our region.  Widespread precipitation may occur late Saturday night into Monday morning.  At this time, the best chance of precipitation appears to be on Sunday.

With cold air in place we may be dealing with freezing rain, sleet, and snow.  The frozen precipitation may change over to all rain before ending.

There remain significant questions about temperature profiles on Sunday.  Monitor updates.

Models typically try to push cold air out faster.  Cold air can be difficult to dislodge.  This will need to be monitored.

Here is what the GFS guidance is showing for Sunday and Sunday night.

Here is the GFS model guidance rainfall ensemble mean.  Strong signal for a system later this weekend.

The GFS is painting rain totals of 0.40″ to 0.80″.
.

.

Future-cast radar images from 12 PM Sunday through 6 AM Monday.  Green represent rain.  Pink represents sleet and freezing rain.

This is the GFS model guidance.

As you can see, the GFS is warm and it is showing a rain event.
.

.
The EC guidance also shows a rain event.

Here are the snow totals into Monday.    As you can see, the EC model paints snow to our north.

I will monitor the guidance trends over the coming days.
.

.

Cold weather will generally be the rule over the coming weeks.

Here is the GFS ensemble temperature anomaly map.  Anomaly maps show you how many degrees above or below normal temperatures will be.

This is an animation and may take a little time to load (depending on your internet speed).

A LARGE chunk of the nation is expecting below normal temperatures. Those green and purple colors are below to well below normal temperatures.

The cold air just keeps coming.  We will have to wait and see just how cold.  There is a lot of snow cover to our north.  That helps keep the temperatures colder as it moves south and east.  It does not moderate as fast.

Beau’s Winter Weather Outlook

It is important to remember that this pattern is fluid.  There is always going to be lower than normal confidence, during the winter months, for the forecast past day three or four.
.


.
Here are my latest snow probability maps for the week ahead.

Breaking it down between snow and ice.

Just a small chance of a trace of snow on Friday.  Flurries perhaps (if that).
.

.

The larger system arrives on Sunday.  It might end up a rain event.  Warmer air is forecast to surge northward and push the freezing line away from our area.

It is still a bit early to know for sure.  Monitor updates.

I do have a wintry mix in the forecast late Saturday night into Sunday.

.

.
These have been updated with the latest data.

These graphics show you the % chance of one inch or more of snow and/or accumulating sleet and freezing rain.

I am monitoring Friday for flurries.  The Sunday system is larger.  Widespread rain or wintry mix is likely on Sunday.  The timing of the event will need to be monitored.  The frozen precipitation may change to all rain.  Warmer air is forecast to move into the area during the weekend (esp on Sunday).

We offer regional radars and local city radars – if a radar does not update then try another one. Occasional browsers need their cache cleared.  You may also try restarting your browser.  This will usually fix any problems.

During the winter you can track snow and ice by clicking the winterize button on the local city view interactive radars.
