48-hour forecast

Monday to Monday

1. Is lightning in the forecast? Yes.  I am monitoring Friday through Monday for additional thunderstorm chances.

2.  Are severe thunderstorms in the forecast?  Possible.  Thunderstorms could be intense this coming weekend.  For now, I am monitoring the model guidance.  There is not a strong signal for severe weather.  Monitor updates.

3. Is flash flooding in the forecast? Not at this time.  Thunderstorms can briefly produce very heavy downpours.  That could briefly cause ponding of water on roadways.

4. Will the heat index exceed 100 degrees?  Not at this time.

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

6.  Is measurable snow and/or sleet in the forecast?  No.

7.  Is freezing rain/ice in the forecast?  No.
Freezing rain is rain that falls and instantly freezes on objects such as trees and power lines

Weather Highlights

    1.    Showers and thunderstorms moved across the region Sunday.  Some locations received much needed rainfall.
    2.    Weather pattern shifting.
    3.    Widespread rain to our south mid-week.  May clip our region (esp southern counties).

 

Weather advice:

Make sure you have three to five ways of receiving your severe weather information.

Don’t forget the sunscreen on this summer warm days!

Forecast Discussion

Today’s Forecast Numbers

Monitoring rain chances over the coming two weeks.

Widespread/much needed rain fell over the region Sunday and Sunday evening.  Some of the rain was heavy.  There were reports of greater than 2.7″ in some counties.

A widespread 0.3″ to 0.6″ fell with numerous locations receiving 0.6″ to 1.2″.  Then, there were pockets of 1.2″ to 2.0+ inches.

Other locations, unfortunately, did not receive nearly as much rain.  That was the forecast.  Some locations would not receive much.

Here is a radar image of radar indicated rain totals.  Again, there were LARGE differences even within counties.

Warm season rain events are often like that.  Hit and miss when it comes to totals.  Totals are greatly enhanced by thunderstorms.  Thunderstorms can easily double your rain totals in a short amount of time.

We do have additional rain chances in the forecast.

As mentioned in previous posts, my greatest concern for the Tuesday/Wednesday and Thursday rain events has been just how far south the rain would track.

It continues to appear as if the greatest rain totals, during the Tuesday/Wednesday and Thursday time-frame, will be across Arkansas, Tennessee, and the southlands.

What is the probability of 0.50″ or greater of rain falling Tuesday night into Wednesday.

You can see that it is centered to our south.

The WPC also has the highest totals in that area.  The WPC is a branch of NOAA/NWS.

Our region may be clipped by the Tuesday through Thursday rain events.

I do have very low-end rain chances in the forecast, during this time frame, over our far southern counties.  The highest probabilities will be across the Missouri Bootheel into western Tennessee.   Rain probabilities decrease as you travel farther north.

Even across the Bootheel and northwest Tennessee, the chance of rain will be low (don’t expect much).

Our next chance of rain will arrive with some northwest jet-stream flow events.

What is northwest flow?  That is when the jet-stream dives down from Canada and the Northern Plains.  It then pushes southeast into our region.

During the summer months, this can produce MCS’s.  Thunderstorm complexes.

The chance of rain will be with us into the weekend. I am going to have to fine-tune the exact timing of storm complexes and their exact track.

Each track should be a bit slightly different.  The track is key to who receives much needed rainfall.

The good news is that the pattern has completely broken down and changed across North America.  The big omega block, which kept us very dry, is gone.

We now have better chances of receiving measurable rainfall.  It will just be a matter of tracking each system.

Let’s look at some data.  Don’t get too caught up in the exact details of each system (this far out).  I look at the general overall pattern.

The EC model shows a system this coming Friday moving in from the northwest.

The EC model shows a system next Monday/Tuesday coming in from the northwest.

Let’s look at some 500 mb vorticity charts.

Vorticity charts show where lift is located.  Storm systems that might produce rain.

For example, here was the Sunday system (yesterday’s system).

See the bright red colors over our region?  That is the system that brought our much needed rainfall.

.

Here is the Tuesday/Wednesday system.  Mainly to our south.

.

Here is the Friday system on the EC model guidance.

.

Here is the system next Monday/Tuesday

The systems are difficult to forecast days in advance.  Often times, these MCS (thunderstorm complexes) are difficult to forecast event the day of the events.

I will be monitoring the data and updating the forecast accordingly. Hopefully, we receive some rain over the coming weeks.  That will help the gardeners and farmers.

Temperatures will be seasonably warm over the coming seven to fourteen days.

This outlook covers southeast Missouri, southern Illinois, western Kentucky, and far northwest Tennessee.

Today through April 18th:  A couple of the Saturday afternoon and night thunderstorms could produce damaging wind and hail.  The tornado risk is low, but not zero.  Mainly over Missouri for the tornado risk.  The line will weaken with time as it moves farther east.

 

.

Today’s Storm Prediction Center’s Severe Weather Outlook

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.
