An explanation of what is happening in the atmosphere over the coming day

2014-11-24_13-38-04

Severe thunderstorm outlook.

Remember that a severe thunderstorm is defined as a thunderstorm that produces 60 mph winds or higher, quarter size hail or larger, and/or a tornado.

Monday night:  Organized severe weather is not anticipated.  A few storms could be on the heavy side with small hail and gusty winds.  The risk for severe weather is less than 10%.

Tuesday:  A few thunderstorms are possible.  Lightning is the main concern.

Tuesday night through Wednesday night:  Severe weather is not anticipated.

Thursday into Friday:  Some storms area possible.  It is too soon to know if severe weather is a concern.

———————————-

Your day by day analysis 

Monday night into Tuesday night:

A slow moving cold front will deliver shower and thunderstorm chances into Tuesday morning.  Southeast Missouri and southwest Illinois will likely have some sun on Tuesday with rain chances ending early.  Rain chances may linger over western Kentucky and western Tennessee.

Rainfall totals will vary.  Heavier totals will occur where thunderstorms develop or train.  Generally, I am anticipating 0.25″ to 0.50″ of rain.  A few spots will probably top a half an inch.

Let’s take a look at three different rainfall forecasts.

These maps won’t be exact.  Don’t take specifics from them.  Take generalities.

You can see heavier bands of rain on these maps.  That is caused by thunderstorms.

This first one is the high resolution 3K NAM guidance

This next image is the lower resolution NAM

Here is the NOAA forecast

Organized severe weather is unlikely.  CAPE values (measure of energy) will remain on the low side.  Wind fields will be strong, but without instability it won’t be able to produce much in the way of severe weather.  A couple of storms could produce small hail and gusty winds.  Lightning is always a concern for outdoor events.  The risk for severe weather is less than 10%.  Severe weather is defined as quarter size+ hail or 60 mph+ winds.

The frontal boundary responsible for the showers and storms will push out of the region by Tuesday night.  Any remaining showers will come to an end.

Here is the 3K NAM model guidance future-cast radar.  What radar might look like Monday night into Tuesday.

This is one model’s opinion and won’t be exact, but you get the general idea.

 

Wednesday into Wednesday night should remain dry.

Another system pushes towards our region on Thursday with at least some risk for a shower or thunderstorm.  Confidence on the Thursday through Sunday time-frame is rather low.  A slow moving frontal boundary may stall over our region.  If that happens then there will be daily chances for scattered showers and thunderstorms.

Temperatures from now through the weekend should remain mild.

Here is the GFS model’s take on the late week rain chances.  The forecast is muddled because I am not sure if the front stalls over our region.  This part of the forecast will need to be fine tuned.  I know several of you have activities planned for this coming weeks.  I will keep an eye on the trends in guidance.

This first map is for Thursday evening.  Green represents showers.

This next image is for Friday afternoon

This next image is for Friday night

This next image is for Sunday evening

This next image is for Tuesday morning

We have 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. That usually fixes the problem. Occasionally we do have a radar go down. That is why I have duplicates. Thus, if one fails then try another one.

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

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, email, texts, and this blog
  • Minimize the “hype” that you might see on some television stations or through other weather sources
  • Push you towards utilizing wall-to-wall LOCAL TV coverage during severe weather events
