An explanation of what is happening in the atmosphere over the coming days…

Highlights

1.  Clipper system moving into the region on Monday night/Tuesday
2.  MUCH MUCH warmer later this week
3.  Is winter over?

We have a couple of weather stories to follow over the coming days.  The biggest story will be near record warmth later this week. But, first we have another clipper diving into the region from the northwest.

Precipitation will push out of Iowa and Missouri later tonight into Tuesday morning.  It will rapidly dive south and east into the morning hours.  Typically these systems are fast movers.  And, this one will be no different.

Widespread rain and rain/snow rain/wintry mix is forecast to push into our northern and northwestern counties after 2 AM Tuesday morning.  The bulk of the precipitation will probably fall between 4 am and 12 pm on Tuesday morning.

Temperatures are forecast to dip below freezing tonight.  Freezing rain could be a concern.  There is a significant warm layer aloft with this system.  That means that snowflakes might melt on their way down and then refreeze as surface temperatures are below freezing.

Snow chances would probably be limited to the Mt Vernon, IL area into southeast Illinois.  Although even in those areas temperatures aloft may be too warm for snow.  Thus, ice would be the primary concern.
If you have travel plans late Monday night into Tuesday morning then monitor updates.

Here is the future-cast radar from weatherbell.com

This is the NAM/WRF model

Green is rain.  Purple is wintry mix.  Blue is snow.  You can see that parts of our region are all of the above.  That means the model really is not sure what type of precipitation will fall.

This is the 2 am to 4 am time frame.  You can see precipitation moving in from the northwest.  It is moving southeast.

This is the 5 am to 7 am time frame.

hires_ref_mw_25 - Copy

This is the 7 am to 9 am time frame.

hires_ref_mw_28 - Copy

And, this is the 11 am to 1 pm time frame.

Temperatures are forecast to rise during the morning hours.  If this does start out as a wintry mix then it should change to rain by mid or late morning.  Again, some question marks on precipitation type.  Especially true the further north and east you travel in our region.

WARM UP IS ON THE WAY!!!!

The next BIG story will be a huge warm up later this week.  By Thursday, Friday, and Saturday temperatures are forecast to rise into the 50s/60s.  What a difference one week makes.

Yes, you can mail me some chocolate chip cookies for that one.  🙂

And, it is official.  A car wash watch has been issued for Thursday-Saturday.

2016-02-15_11-55-02

I suspect everyone will enjoy the break.  Car washes will be busy as beavers!  People will open their windows and let some fresh air into the house.  I doubt there will be many complaints about the weather later this week.

Here are the temperature forecast numbers for 12 pm on Thursday, 12 pm on Friday, and 12 pm on Saturday.  Temperatures will rise a few more degrees during the afternoon hours.  You get the general idea.  Spring fever might take hold?

I will be watching for perhaps some showers or even a thunderstorm around Sunday or Monday.  Long way off.  Plenty of time to monitor that time frame.  A cold front is forecast to push into the area from the north over the weekend.  Then, perhaps return as a warm front.

Is winter over?

My thinking is that winter is not over.  We still have more to go.

Long range charts show multiple pushes of cold air over the next 2-4 weeks.  Could we still have more snow and ice?  Yes, we certainly could.  I know some of you have had very little snow so far this winter.  Especially true over southeast Missouri and southwest Illinois.  I would not give up yet.

Did you know that the Paducah, Kentucky NWS is only one inch shy of reaching a top ten snowiest winters?  Hard to believe for those of you who have missed out on most of the snow events.  Location, location, location.  I say it all the time.  Winter storm tracks are KEY to how much snow falls at any given location.

Yes, with each passing day and with each passing week we draw closer to spring.  We will trade the snow and ice for thunderstorms.  Let’s enjoy the season at hand.

 

winterstorm

A clipper system moving into the region from the northwest on Monday night and Tuesday morning could produce a rain rain/snow wintry mix over parts of southeast Missouri into southern Illinois and west Kentucky. Freezing rain could cause roads to become slick late tonight into early Tuesday morning.  Temperatures should rise above freezing by mid or late morning on Tuesday.

2014-11-24_13-30-38
Monday night – Rain and/or a wintry mix possible late tonight into Tuesday morning.
Tuesday – Wintry mix possible in the morning.
Wednesday – No snow or ice anticipated.
Thursday – No snow or ice anticipated.
Friday –  No snow or ice anticipated.
Saturday –  No snow or ice anticipated.
Sunday – No snow or ice anticipated.

Adjustment precipitation probabilities for Monday night/Tuesday morning.

 

whatamiconcered

Main concern will be ice late tonight into Tuesday morning.  Use care if you have to drive late tonight into Tuesday morning.  Temperatures should rise above freezing around mid morning on Tuesday.

willineedtotakeaction
Slick roads are possible on Tuesday morning.

wildcard

The wild card in this forecast will be the incoming storm system on Monday night and Tuesday morning.  Will it be rain, freezing rain, or snow.  Perhaps all three.  Warm layer aloft indicates ice is possible on Tuesday morning.

rainfallforecastHow much precipitation should we expect over the next few days?

Rain or a mix of rain/snow will push back into the region on Monday night and especially on Tuesday morning.  Right now this appears to mostly be a rain system.  Rain totals will vary across the region.  Best chances for 0.25″+ will be over southern Illinois and western Kentucky.  Southeast Missouri should pick up 0.10″-0.25″.

Temperatures will be marginal for a wintry mix.  Believe impacts would be minimal.  But, let’s keep an eye on it.  Occasionally dynamic systems like this can produce a burst of heavy/wet snow.

Official precipitation forecast numbers for this event.  This is through Tuesday afternoon.  Precipitation will end during that time frame.  The next chance of rain should hold off until later this weekend.

Can we expect severe thunderstorms over the next 24 to 48 hours?  Remember that a severe thunderstorm is defined as a thunderstorm that produces 58 mph winds or higher, quarter size hail or larger, and/or a tornado.

The thunderstorm threat level will be a ZERO through Saturday.  Some indications of a chance for thunderstorms around Sunday.  Will monitor.

Who do you trust for your weather information and who holds them accountable?

I have studied weather in our region since the late 1970’s.  I have 37 years of experience in observing our regions weather patterns.  My degree is in Broadcast Meteorology from Mississippi State University and an Associate of Science (AS).  I am currently working on my Bachelor’s Degree in Geoscience.

My resume includes:

Member of the American Meteorological Society.

NOAA Weather-Ready Nation Ambassador. 

Meteorologist for McCracken County Emergency Management.  I served from 2005 through 2015.

I own and operate the Southern Illinois Weather Observatory.

Recipient of the Mark Trail Award, WPSD Six Who Make A Difference Award, Kentucky Colonel, and the Caesar J. Fiamma” Award from the American Red Cross

In 2009 I was presented with the Kentucky Office of Highway Safety Award. 

Recognized by the Kentucky House of Representatives for my service to the State of Kentucky leading up to several winter storms and severe weather outbreaks.

I am also President of the Shadow Angel Foundation which serves portions of western Kentucky and southern Illinois.

There is a lot of noise on the internet.  A lot of weather maps are posted without explanation.  Over time you should learn who to trust for your weather information.

My forecast philosophy is simple and straight forward.

  • Communicate in simple terms
  • To be as accurate as possible within a reasonable time frame before an event
  • Interact with you on Twitter, Facebook, and the blog
  • Minimize the “hype” that you might see on television or through other weather sources
  • Push you towards utilizing wall-to-wall LOCAL TV coverage during severe weather events
