Here is the latest WPC / NOAA Rainfall charts

This graphic will not cover those wild swings in rainfall totals that occur from locally heavy thunderstorms.  These number will be greatly underdone where slow moving thunderstorms occur.

Most of this falls Sunday into Tuesday.

There are quite a few model guidance packages that show less rainfall totals across portions of the region.  This may be a concern for those in need of rain.

Click to enlarge graphics on this page

 

 

Here is the latest NAM model rainfall forecast

Notice that area where less precipitation occurs?  In or near our region.  That seems fairly likely to happen.  The question is placement.

I know many of you need rain.

The placement of lesser rain totals favors our southern counties.

 

 

Here are the GFS ensembles

Notice the area of less precipitation?  Again, this is a concern for some of us.

Click to enlarge this graphic.  It is a bit hard to read.  This is the southern United States.  Our area is located in the upper right portion of each square graphic.

 

 

What are ensembles?  I am glad you asked!

 

 

Bottom line, some of you may receive considerably less rainfall than others.

The National Weather Service defines a severe thunderstorm as one that produces quarter size hail or larger, 58 mph winds or greater, and/or a tornado.

 

Sunday through Tuesday:  Thunderstorms are possible Sunday into Tuesday.

There is a low end risk of strong thunderstorms across southeast Missouri and southern Illinois Sunday into Sunday night.  The main concern would be gusty winds.

There is a low end risk of strong thunderstorms across the entire region Monday into Monday night.  The main concern would be isolated strong wind gusts.

Locally heavy rain will be a concern with PWAT values of 1.7″ to 2.0″.  That is a lot of moisture for storms to tap into.  Remember, PWAT is a measure of moisture in the entire atmosphere.

 

===============================

Summer thunderstorms can produce isolated microbursts.

microburst winds can exceed 50 mph.

What are microbursts?

Weather Headlines

  1. Unsettled couple of days
  2. Some of you may end up with very little in the way of rain totals
  3. Shower and thunderstorm chances today into Tuesday
  4. Mostly dry Wednesday into the weekend
  5. Warm

 

We will have an unsettled period of weather over the coming 48 to 72 hours.

The main concern will be on and off shower and thunderstorm chances.  There will be locally heavy rain where thunderstorms occur.

The bulk of the region should pick up 0.40″ to 0.80″ of rain.  There will be some locations exceed two inches of rain.  That would be where thunderstorms occur.  PWAT values are high.  Lot of moisture to work with.

We do need rain.  Many areas are a bit on the dry side.  Thus, this rain will be welcome by many.

Here is the latest SPI index (a measure of moisture).  This shows you the last 30 days of precipitation departures.

 

 

The overall risk of severe weather is small.  I can’t rule out a few reports of strong and gusty winds.  The Storm Prediction Center has outlined portions of the region for strong storms today and again on Monday.

Keep in mind, this is just a model and models are never exact.  This just gives you a general idea of the possibilities.

The time stamp is located in the upper left portion of the animation.

This is the NAM model future-cast radar animation.

 

 

Here is another model.  This is the GFS model.

 

 

We should dry out Wednesday into the weekend.  Some models are showing isolated showers and thunderstorms.  For now, I have left the forecast dry.

It will remain warm into the weekend.  We will flirt with the upper 80’s to around 90 degrees Friday into Sunday.

Did you know that a portion of your monthly subscription helps support local charity projects?

You can learn more about those projects by visiting the Shadow Angel Foundation website and the Beau Dodson News website.

I encourage subscribers to use the app vs regular text messaging.  We have found text messaging to be delayed during severe weather.  The app typically will receive the messages instantly.  I recommend people have three to four methods of receiving their severe weather information.

Remember, my app and text alerts are hand typed and not computer generated.  You are being given personal attention during significant weather events.
