7-day forecast for southeast Missouri, southern Illinois, western Kentucky, and western Tennessee.

This is a BLEND for the region. See the detailed region by region forecast further down in this post.

The SEVERE WEATHER BLOG has been activated for the threat of heavy rain and potentially a couple of severe thunderstorm warnings.

Wednesday to Wednesday

1. Is lightning in the forecast?  Yes.   Wednesday, Wednesday night, Thursday, and then Sunday, Monday, Tuesday, and Wednesday

2. Are severe thunderstorms in the forecast? Monitor.  There is a chance of a few severe thunderstorms today and tonight.  A lower risk Thursday.  I am watching next week, as well.

The primary concern would be damaging wind and perhaps an isolated short-lived tornado.  Remember, it only takes one severe thunderstorm to ruin the day.  Monitor updates.  Instability is in question with this event.

The NWS officially defines a severe thunderstorm as a storm with 58 mph wind or greater, 1″ hail or larger, and/or tornadoes

3. Is flash flooding in the forecast? Yes.  Locally heavy rain is likely Wednesday into Thursday.  If thunderstorms train over the same areas, then some locations could exceed two inches of rain.  There is disagreement among the models as to the exact placement of the heaviest rain totals.  It is possible there are two areas of higher totals.  One across portions of SE MO and south IL and a second max from the Bootheel into Kentucky.  This will need to be monitored.  Locally  heavy rain is likely with this event.  Some locations could top four inches of rain.  Some of the data shows greater than five inches.

4. Will the heat index top 100 degrees? No.

5. Will the wind chill dip below 10 degrees above zero? No.

6. Will there be accumulating snow and ice in the forecast?  No.

Today through May 3rd.

The SEVERE WEATHER BLOG has been activated for the threat of heavy rain and potentially a couple of severe thunderstorm warnings.

Here is the link for the SEVERE WEATHER BLOG.  CLICK HERE.

Some thunderstorms could be severe with damaging wind being the primary concern.  There could be an area of higher risk over portions of southern Illinois, Kentucky, far southeast Missouri, and northwest Tennessee.  There is higher than normal uncertainty about the placement of the greater risk zone.

The Storm Prediction Center is closely monitoring the situation for both today and Thursday.  There may have to be a higher risk zone introduced.  That would likely be a slight risk (level 2 of 5).  Let’s keep an eye on it.

Locally  heavy rain is likely with this event.  Some locations could top three inches of rain.  Some of the data shows greater than four inches.

Another thunderstorm episode is possible next Tuesday or Wednesday.  Several days to monitor that event.

.

.

Today’s outlook (below).

Light green is where thunderstorms may occur but should be below severe levels.

Dark green is a level one risk. Yellow is a level two risk. Orange is a level three (enhanced) risk. Red is a level four (moderate) risk. Pink is a level five (high) risk.

One is the lowest risk. Five is the highest risk.

A severe storm is one that produces 58 mph wind or higher, quarter size hail, and/or a tornado.

The tan states are simply a region that SPC outlined on this particular map. Just ignore that.

The black outline is our local area.

48-hour precipitation outlook.

72-hour precipitation outlook.

.Weather advice:

Locally heavy rain Wednesday into Thursday.  Some roadways could flood.  Training showers and thunderstorms will be the culprit.   Training is when thunderstorms repeatedly move over the same areas.

Some thunderstorms could produce high winds.

.

Weather Discussion

    1.   Flash flood watch for portions of the region.
    2.   Very heavy rain likely with this event in SOME counties.  More than four inches likely for some.
    3.   Widespread one to three inch rain event.
    4.   I had to add shower/storms to the Sunday forecast into next week.  Heavy rain likely at some point from that series of storm systems, as well.
    5.   River flooding concerns are rising.

.

7 AM Wednesday

I updated all of the graphics.

The SEVERE WEATHER BLOG has been activated for the threat of heavy rain and potentially a couple of severe thunderstorm warnings.

Here is the link for the SEVERE WEATHER BLOG.  CLICK HERE.

Flash flood watch.  More counties may be added.

 

Widespread showers and thunderstorms are developing on radar.  As of this writing, at 6 AM, there were numerous showers and storms already showing up from Texas into Illinois.  This will only increase through today and tonight.

Some of the high resolution models indicate bands of greater than four inches of rain.  A flash flood watch was issued for portions of the region.  I can’t rule out more counties being added.

Even though recent ground conditions have been mostly dry, rains of this magnitude could cause problems.  River flooding is likely in some areas due to the widespread nature of the heavy rain.

There remain some questions about the exact placement of the heaviest rain totals.  For now, portions of southeast Missouri and southern Illinois continue to be signaled for a band of three to five inches of rain.  Locally higher possible.

As far as far southeast Missouri, the Bootheel, extreme southern Illinois, western Kentucky, and northwest Tennessee…we should remain on alert for the potential of very heavy rain, as well.

Either way, a widespread one to three inch rain event is likely.  This could flood some roadways.

The GFS ensemble plumes are showing a medium reading of 2.57″ for Paducah.  This continues to rise with each run of the GFS model.  It is a strong signal for locally heavy rain.

.

I continue to monitor the risk of a few severe thunderstorms.  The primary concern would be damaging wind gusts, although a brief tornado can’t be ruled out.  This is highly dependent on surface instability rising.  CAPE is what we call that.  Surface CAPE is normally associated with severe thunderstorms.

The Storm Prediction Center has outlined our region in a marginal risk.  That would be upgraded to a level two (slight risk) if we had a bit more CAPE to work with.  Let’s monitor it.

.

PWAT values will be high for an extended period of time.  This is a locally heavy rain signal.

Hrrr model PWAT anomaly animation.  A long stretch of moisture with this next system (mid-week).  That is an indication that some locally heavy rain may occur.

The dark blue and purple zone are where moisture levels are highest.  The longer that lingers over one spot, the greater the chance of heavier rain totals.

 

.Dew point is used to determine moisture in the lower levels.  A few point around 70 is muggy air.

Check out the Hrrr high resolution model forecast for dew points.  This is a copious of amount of moisture for thunderstorms to tap into.

.

Here is the NOAA rainfall forecast through Thursday.

Click on the images to enlarge them.

.

NOAA/WPC does have portions of our region in a martingale to slight risk of excessive rainfall.  That simply means there could be enough rain to trigger some water issues.  Let’s keep an eye on the placement of the yellow zone.

Today and tonight

.

And the Thursday excessive rainfall outlook.  This may need adjusting further northeast with the slight risk zone.

NAM 3K model.  Look at the significant differences in the guidance.

.

Hrrr model through Thursday.

The Hrrr has always been further south with the heaviest rain vs the other models.  This is something that needs to be watched.

.

GFS model continues to slowly edge southward.

.

We dry out Thursday afternoon and night.  Dry Friday through Saturday night.  I had to increase shower/thunderstorm chances Sunday night into next week.

Some of the data shows rain Sunday afternoon.  Let’s keep an eye on it.  Either way, it appears rain chances will return at some point Sunday into next week.  I can’t rule out locally heavy rain.

Of some concern, PWAT’s next week.  They return to very high numbers.  This could mean more heavy rain.  Not what we want to hear.

.

Needless to say, the risk of river flooding over the next few weeks will be higher than normal.  Especially true if we have heavy rain next week (on top of this event).

Additional flash flooding is also likely if next weeks event pans out, as well.

Again, as a reminder, these are models. They are never 100% accurate. Take the general idea from them.

What should I take from these?

  1. The general idea and not specifics. Models usually do well with the generalities.
  2. The time-stamp is located in the upper left corner.
  3. The EC European weather model is in Zulu time.

.

What am I looking at?
You are looking at different models. Meteorologists use many different models to forecast the weather. All models are wrong. Some are more wrong than others. Meteorologists have to make a forecast based on the guidance/models.

I show you these so you can see what the different models are showing as far as precipitation. If most of the models agree, then the confidence in the final weather forecast increases.

You can see my final forecast at the top of the page.
