Tuesday to Tuesday

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

2. Are severe thunderstorms in the forecast? Monitor.

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 Wednesday 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.

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 three inches of rain. Some of the data shows greater than four 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.

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.

Tomorrow’s severe weather outlook.

The images below are from the WPC. Their totals are a bit lower than our current forecast. I wanted to show you the comparison.

.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. Warm today! Windy.
2. Rain chances will ramp up tonight into Thursday.
3. Locally heavy downpours but the severe risk appears small.

6 AM Tuesday.

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.

It will be quite warm today. St Louis, Missouri, area could reach the middle 80s. I would not be surprised if there are some upper 80s in that area.

Our region will solidly be in the 80s, as well.

Tuesday

Rain Wednesday and Thursday will keep temperatures a bit lower (at least over MO/IL).

Check out Saturday and Sunday’s temperatures. I did increase them a bit.

Saturday

Sunday

Monday

Enjoy today’s warm temperatures.

There will be gusty winds over the region today. As a matter of fact, winds may gust above 35 mph Tuesday.

I would not be surprised to see some gradient winds top 40 mph. Gradient winds are from the barometric pressure difference over the region.

Widespread showers and thunderstorms will develop late Tuesday night into Wednesday morning. Some of these thunderstorms could be prolific rain producers. As a matter of fact, there has been an uptrend in guidance over the past 24 hours.

Some of the high resolution models indicate bands of greater than four inches of rain. This will need to be monitored for the possibility of flood or flash flood warnings.

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 is a higher than normal uncertainty surrounding the evolution of the two areas of concern. The northern and western half of southeast Missouri and southwest and northern southern Illinois and then that second potential max zone from the Missouri Bootheel into western Kentucky.

Perhaps the greater uncertainty centers around the Bootheel into Kentucky potential. Perhaps extreme southern Illinois.

The bottom line is that there is a lot of moisture for this event to work with. A deep warm layer will also aid in the development of heavy rain.

Monitor updates if you have water concerns.

Area-wide, I am forecasting a 1.00″ to 3.00″ rain event. With pockets of three or more inches likely over southeast Missouri and southern Illinois.

The GFS ensemble plumes are showing a medium reading of 2.45″ for Paducah.

This is a decent increase from yesterday’s update.

The severe weather risk has increased just a tad. Model guidance indicates the potential of a few thunderstorms producing pockets of wind damage. Although the severe weather risk is not great, it is enough to warrant our attention. Monitor updates both Wednesday and Thursday. A few storms could become severe.

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

GFS 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.

This chart shows you PWAT values for Carbondale, Illinois. The days are at the bottom. The PWAT values are on the right axis.

The left side is the number of ensembles. Ensembles are a model that they run over and over again to see if each run agrees with the next one.

The more that agree, the higher the confidence in the forecast. These are very high numbers for late April. Two standard deviations high. What does that mean? It means there is a lot of moisture in the atmosphere for thunderstorms to work with.

Click to enlarge.

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

Check out the NAM 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.

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

Flash Flood Guidance

Three hour rain totals to trigger flash flooding

Click on the images to enlarge them.

Six hour rain totals to trigger flash flooding

You can see there are difference in the guidance. Check out the NAM 3K. Very little rain on the southern end of this system. This raises concerns about eventual rain totals.

Confidence in heavy rain across parts of southeast Missouri and southern Illinois remain high.

Confidence from the Bootheel of Missouri into extreme southern Illinois, western Kentucky, and northwest Tennessee remain low.

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

What should I take from these?

The general idea and not specifics. Models usually do well with the generalities.
The time-stamp is located in the upper left corner.
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.
