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

  1.   Thunderstorms over the coming days.  Some possible intense.
  2.   Cooler by the weekend

The main weather concern continues to be thunderstorm chances over the coming days.  Let me try to break it down.

It will not rain all of the time.  Plenty of dry periods mixed into the forecast.

Monday night:  A disturbance advances into our region from the southwest and west.  This system will likely spark widespread showers and locally heavy thunderstorms.  Instability levels are marginal for severe weather.  Wind fields are strong enough to warrant at least the mention of severe weather.  Especially true for southeast Missouri.  There could be an enhanced threat area near the Missouri Bootheel and northwest Tennessee.  Damaging winds will be the main concern.  Although, the tornado threat is not zero.

Locally heavy rain is likely on Monday night.  PWAT values (a measure of moisture in the atmosphere) is going to be high.  Thus, some heavy rain is a good bet.  Where thunderstorms are slow moving or train over the same area you could pick up a quick 0.50″-1.5″ of rain.  Stronger storms can always produce locally heavier totals.

Precipitation should come to an end, for the most part, on Tuesday morning.  Still, at least a chance for a few showers and storms scattered around the area during the morning hours.  But, the bulk of the precipitation should push off to the northeast.

The atmosphere will recharge on Tuesday afternoon and evening.  CAPE values will top 2000 over our region.  CAPE is a measure of energy in the atmosphere.  CAPE is used to determine the potential for severe weather.  One ingredient, at least.

Wind fields won’t be all that strong on Tuesday afternoon and night.  But, perhaps sufficient for a few storms to become severe.  Hail and high winds would be the main concern.  Tornado risk is not zero.  Monitor updates, as always.

There is some question as to thunderstorm coverage on Tuesday afternoon and night.  Keep that in mind.  Not a slam dunk forecast for everyone.

On Wednesday our instability may peak.  CAPE values could top 3000 on Wednesday.  But, it is questionable as to how much thunderstorm activity will form during the day.  Perhaps a better chance after 4 pm into the overnight hours.  IF storms form then they could become severe.  Once again you will want to monitor updates on Wednesday.

Thunderstorm chances will decrease on Thursday through Sunday.  But, we will have some weak disturbances and a cold front in the area.  Thus, rain shower chances probably won’t be zero during this time period.  See the details probabilities in the day by day forecast at the top of the page.

Latest data indicates we may have to deal with thunderstorms on Sunday and Monday.  Low confidence.  Low confidence on the weekend forecast.

Rainfall totals will likely vary considerably over the coming days.  Widespread 0.50″-1.00″ appears likely.  Then, pockets of 1-2″ possible.  And, higher totals are possible where thunderstorms train over the same area.

Here are some future-cast radar maps for the next 24-48 hours.

These images are from weatherbell. com

This first image is for Monday evening at 7 pm.  Some storms over parts of the region.  Storms will be pushing east and northeast.

This won’t be exact.  It is simply guidance.  The high resolution HRRR indicates a line of storms moving into the region between 7 pm and midnight.

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.

.
A level THREE severe weather threat will be with us on Monday night through Wednesday night.  There could be periods of time when the threat level will need to be raised.

Main idea to take from this forecast is monitor updates.

level3_2
Monday night:  Strong to potentially severe storms are possible.  Monitor updates.  Believe the greatest area of concern on Monday night will be the Missouri Bootheel.  But, elsewhere we could have some intense storms, as well.
Tuesday and Tuesday night:  Strong to potentially severe storms are possible.  Monitor updates.
Wednesday morning:  Severe storms are not anticipated
Wednesday afternoon and night:  Severe storms are possible.  Monitor updates.
Thursday:  Severe storms are not anticipated
Friday:  Severe storms are not anticipated.
Saturday and Sunday:  Monitor updates

Updated rain chances.  Also updated the weekend forecast.

whatamiconcered

Several concerns for the coming days.  Locally heavy rain is possible with thunderstorms on Monday night – Wednesday night.

Severe thunderstorms are certainly possible this week.   Monitoring Monday night for some intense storms.  Instability is in question on Monday night.  But, wind fields will be sufficient for some stronger storms.  Perhaps the greatest area of concern will be the Missouri Bootheel into northeast Arkansas.

Tuesday and Tuesday night will provide the opportunity for additional showers and thunderstorms.  Again, locally heavy rain and severe storms are possible.

I am also concerned about Wednesday afternoon and night.  Heavy rain possible.  Intense storms are possible.  Monitor updates.
.

willineedtotakeaction
Yes.  Monitor updates frequently over the coming week.  Several rounds of thunderstorms will be possible.  Heavy rain is one concern.  And, some severe storms can’t be ruled out Monday night through Wednesday night.

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

A long week of weather ahead of us.  Several rounds of potentially heavy rain.  Placement of features will be key to your rainfall totals.  Remember, thunderstorms can produce locally higher totals.  And, that will certainly be the case this week.  I would not be a bit surprised if someone tops three inches of rain over the coming days.  Possibly more.

Here is the official broad-brushed rainfall totals for the week ahead.  Again, locally higher totals are possible.

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
