Friday through Sunday

  1. Is lightning in the forecast?  Yes.  Possible Sunday night over The Missouri Bootheel, western Kentucky, and Tennessee.
  2. Are severe thunderstorms in the forecast? No.
    * The NWS officially defines severe weather as 58 mph wind or great, 1″ hail or larger, and/or tornadoes
  3. Is flash flooding in the forecast? No.
  4. Is ACCUMULATING snow or ice in the forecast? Yes.  Sunday afternoon into Sunday night.  The frozen precipitation should turn to rain area-wide.  There could be some accumulation before that happens.  The most likely area of this happening would be from Bollinger, Cape Girardeau, Ste. Genevieve and Perry Counties in southeast Missouri and then Jackson, Randolph, Perry, Franklin, Hamilton, White,  and Jefferson Counties in case it remains colder for a longer period of time.  It is possible that no accumulation occurs if temperatures rise fast enough.   Monitor updates.  The storm track is key.
  5. Will wind chill values drop below 10 degrees? No.

.

Monday through Thursday

  1. Is lightning in the forecast? Yes.  The Missouri Bootheel, western Kentucky, and western Tennessee may experience lightning.
  2. Are severe thunderstorms in the forecast?  Monitor updates: If the low were to track further north then severe weather would be possible over KY/TN.  For now, I believe the low will stay far enough south to spare our area from severe storms.  Monitor.  There could be adjustments.
    * The NWS officially defines severe weather as 58 mph wind or great, 1″ hail or larger, and/or tornadoes
  3. Is flash flooding in the forecast? No.
  4. Is ACCUMULATING snow or ice in the forecast? Unlikely.  Monitor updates.
  5. Will wind chill values drop below 10 degrees? No.

Advice:

Monitor updated forecasts concerning rain and snow this weekend.  The main concern will be Sunday evening into Monday morning

I will keep an eye on Bollinger, Cape Girardeau, Ste. Genevieve and Perry Counties in southeast Missouri and then Jackson, Randolph, Perry, Franklin, Hamilton, White,  and Jefferson Counties in case it remains colder for a longer period of time.

Keep in mind, it only takes a little bit of ice on roadways to cause issues

.

Weather Forecast Analysis

What I know:  

Widespread precipitation will develop late Sunday afternoon into Monday morning.

Temperatures should start out cool enough for a wintry mix over at least our northern counties.   All areas should change to rain.  There could be some impacts at the beginning of the system.

I will need to closely monitor the position of the area of low pressure.  If it tracks further south then we would have more ice and snow.  Further north and this is 99% rain.  Monitor updates.

I have been trending warmer with each passing day of this forecast.

 

What I don’t know:

How quickly precipitation changes to rain over our northern counties.

I will keep an eye on Ste. Genevieve and Perry Counties in southeast Missouri and then Jackson, Randolph, Perry, Franklin, Hamilton, White,  and Jefferson Counties in case it remains colder for a longer period of time.

 

What will the impact be if we do have snow or a wintry mix?

I am leaning towards mostly a rain event.  At the beginning of the event, there will likely be a wintry mix over at least our northern counties.

There is a reason we can’t forecast snow totals days in advance.  Usually, it comes down to the last 48 hours before confidence truly increases.

Forecast discussion:

Click to enlarge.

Calm weather today with some clouds.

We will have clouds and fog tonight into Saturday morning.  Dense fog is possible.  Light rain will develop, as well.  Scattered.  Not widespread.

There will likely be areas of drizzle tonight and Saturday morning.

Here is the NAM model guidance future-cast radar for late tonight into Saturday morning.  This is likely a bit overdone.

Some spotty showers in the region.

.

A larger system develops on Sunday afternoon and that takes us into Monday.

So far, I have been satisfied with the forecast that I have been posting over the last few days.

I like to get within 48 hours of a winter weather event before posting numbers.  I felt confident enough to post a forecast yesterday.  That was a wintry mix changing to rain with some impacts over at least our northern counties.  I continue to adjust that forecast today.

The big question with this system has been the precipitation type.  Typical, in our region.  We always seem to be in the rain and snow line zone.

Rain and snow/wintry mix will likely develop Sunday afternoon and night across our region.  That rain and snow will continue into Monday.

I have been trending warmer with my forecast with each passing day.  That continues to push the icy impacts further north.

There remain questions on the exact track of the area of low pressure.  A shift of 30 to 50 miles would change the forecast and pull the snow/ice further south.  A shift north and my forecast counties have little or no impact.  Keep that in mind.  This system is still three days away.  It is just now being fully sampled by the upper-air data support systems.  In theory, that means the model guidance should trend towards a final solution.

I have made my forecast (yesterday) and adjusted it a bit more today.  You can read that at the top of the page.

There will likely be a wintry mix at the start of this event.  As warmer air pushes northward, the frozen will turn to all plain rain.

The depth of the cold air determines what TYPE of precipitation falls.

.

Those with travel plans on Sunday afternoon into Monday should closely monitor updated forecasts.  There may be icy roadways over at least portions of southeast Missouri and southern Illinois.

It would take a major shift southward for the rest of our region to experience much in the way of icy roadways.

The precipitation will continue into Monday.  The cold front will bring colder air into the region by Monday afternoon and night.  That will change the rain to snow showers.  Little or no accumulation is currently anticipated.  Monitor updates in case the system is stronger/deeper than currently forecast.

Here is what the GFS is showing for snow totals.

VIDEO UPDATES
.

These are bonus videos and maps for subscribers. I bring these to you from the BAMwx team. I pay them to help with videos.

The Ohio and Missouri Valley videos cover most of our area. They do not have a specific Tennessee Valley forecast but they may add one in the future.

The long-range video is a bit technical. Over time, you can learn a lot about meteorology from the long-range video.

NOTE: These may not be updated on Saturday and Sunday.

BAMwx has released its winter forecast. Keep in mind, what you really want to know is not covered in a general winter outlook. What you want to know is how much snow or ice will fall. That is not possible to predict.

The best long-range forecasters can do is to tell you above or below normal temperatures and precipitation.

This initial winter outlook indicates odds favor above-normal temperatures when everything is averaged out from November into March. That does not mean we won’t have cold weather. It just means when you average all of those months together we could end up above normal.

They indicate above-normal snowfall, as well.

Winter analogs. BAMwx found years that have a pattern similar to what we are currently experiencing. Those are called analogs. We can compare previous years with the present.

Their analogs indicate colder than normal across portions of the central and northern United States. They indicate above normal temperatures along the West Coast south and east into Texas.

Blue and purple are below normal (bright green, as well). Yellow and orange are above normal.

Looking back at last year. None of the models handled last year all that well.

Upper air pattern.

Here is the BAMwx temperature forecast. This covers all of winter. They have us in the above normal temperature zone. Near normal just to our north. For now, they have this marked as a low confidence forecast.

Additional winter forecasts will be posted over the next couple of months. This is the preliminary outlook.

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

I have studied the weather in our region since the late 1970s. I have 40 years of experience in observing our regions weather patterns.

My degree is in Broadcast Meteorology from Mississippi State University and a Bachelor of Science (BS).

I am an NOAA Weather-Ready Nation Ambassador. I am the Meteorologist for McCracken County rescue squad. When asked, I assist Ballard and Massac Counties, as well.

I own and operate the Southern Illinois Weather Observatory and WeatherTalk LLC.

There is a lot of noise on the internet. 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

I am a 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.

I was 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.
