The daily outlook can be found at the bottom of this post.

Short term outlook through Saturday night:

Finally, a warming trend will develop over the coming 72 hours.

Many of you woke up to single digit readings, once again.  It has certainly been a cold January (December was also cold).  It has been awhile since we have experienced a winter like this (esp the sustained cold).

Here are the January anomalies.  How many degrees above or below normal have temperatures been each day.

Quite amazing to have these big numbers so many days out of the month.
.

.

For snow lovers, all good things must come to an end.  For those who do not like snow, you will like my forecast.

.

.

.

Lows tonight will dip back into the teens.  Some of the melting today will turn to black ice tonight.  Black ice is simply moisture that refreezes on surfaces.

We will have a some sunshine on Friday, as well.  Temperatures will warm even more.  You can expect widespread middle to upper 30’s on Friday.  A few locations may briefly touch the 40 degree mark.

Dry weather is anticipated through Friday night.

We warm even more Friday night into Saturday.  With this warm up will come a chance for advection fog.  The ground is cold.  The snow is cold, of course.  Warmer air moving over the cold ground and snow pack will likely produce areas of dense fog.  Keep this in mind as we move into Friday night and Saturday.

Clouds will begin to increase Friday night into Saturday, as well.  Patchy light drizzle is a possibility Saturday and Saturday night.  I was going to include it in Friday night’s forecast, as well, but it appears Friday night may remain dry.

I will go ahead and insert a slight chance wording into the Friday night forecast, but I think the chances are higher as we move into Saturday/Saturday night.

The good news is that we will remain above freezing Saturday into Monday morning.

Lows Friday night will dip into the 30’s.  Highs on Saturday will likely climb into the middle to upper 40’s.  I can’t rule out a few reporting stations touching the 50 degree mark for a brief period of time.

Saturday night lows may remain in the 40!

We could have some gusty winds beginning on Friday or Friday night and continuing into Monday.  Winds will occasionally gust up into the 20 to 30 mph range.  Higher gusts possible.

The wind will be because of the tightening pressure gradient across the region between the high pressure to our south and the low pressure to our north.

Pressure gradient is one of the factors when forecasting wind speed.

Sunday into Monday

An area of low pressure will develop in the Central United States on Saturday into Sunday.  This system will track well to our north.  That places us in the warm sector of the system.  Warm sector means rain and not snow.  It could also mean gusty winds and a clap of thunder.

Severe weather ingredients for Sunday night and Monday morning.

  1.  Strong wind fields.  Yes.
  2.  Instability.  Unlikely or very low
  3.  High dew points.  Unlikely (marginal, at best)
  4.  Lift.  Yes.

A couple of ingredients are there for severe weather, but it appears the lack of instability and higher dew points will suppress the chances of severe thunderstorms.

With that said, I would encourage you to monitor updates.

Winds will be quite gusty on Sunday into Monday.  Gusts above 30 mph are likely.

The highest rain chances will occur on Sunday evening into Monday morning.  This is when the cold front should move across our region from west to east.

Here is the GFS future-cast radar.  This is what radar MIGHT look like as we move into Sunday afternoon and Sunday night.

The GFS may be a tad too fast with the timing.  I am thinking Sunday evening into Monday morning.  Rain ending on Monday morning or early afternoon.

I have a feeling our snow will be but a memory by Sunday night and Monday.  Snow lovers will have to wait a bit until snow chances return.

.

.

Rainfall totals of 0.30″ to 0.60″ are anticipated.  Locally higher totals are likely.  This is especially true if thunderstorms form and across southeast Missouri.

Here are my rainfall probability numbers.  What is the % chance of X amount of rain falling.
.
Southeast Missouri

Totals across southeast Missouri may end up a bit heavier than the rest of the area.
.

.
Southern Illinois, western Kentucky, and northwest Tennessee
.

.

With the recent heavy snow pack we could have some water issues in a few locations.  Let’s keep an eye on it.   This does not appear to be a large flash flood event.  Just some pockets of problems could occur.

The snow will likely have melted by the time the line of showers and thunderstorms arrive.

I am watching one or two systems for the middle and end of next week.  Right now projections are for rain.  It is a bit early for certainties.  Monitor updates.

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.
