🌪️ Seven-Day Tornado Outlook ⛈️

May 5th through May 12th

Current riskA low-level risk this afternoon and tonight.  See the graphics below.

Current confidence level: Medium.

Comments:  I will monitor this afternoon and tonight.  Mainly over southeast Missouri and western Tennessee.  Mostly along the MO/AR border.  The threat should lessen as you travel into Kentucky and Illinois.

I will send out app alerts if necessary.

Seven-Day Hazardous Weather Outlook

1. Is lightning in the forecast?  Possible.  Today through Wednesday night.  Another chance on Friday evening and night.  Another chance on Sunday and Monday.

2.  Are organized severe thunderstorms. MONITOR.  A few storms could be intense this afternoon and tonight.  The primary concern will be strong wind gusts and a few reports of large hail.  Again, the risk is higher over southern Missouri, the Missouri Bootheel, and western Tennessee.

3. Is significant or widespread flash flooding in the forecast? UNLIKELY.  If thunderstorms track over the same areas from today into tomorrow, a few areas could see ditch and small stream flooding.  Common areas that have issues when heavy rain occurs.

4. Will non-thunderstorm winds top 40 mph? NO.    

5. Will the temperature rise above 90 degrees?  NO.    

6. Is the heat index forecast to rise above 100 degrees? NO.

⛈️ Here is the short-range thunderstorm concern meter.

.

Here is today’s Storm Prediction Center’s (NOAA/NWS) severe weather Outlook.

It appears the risk is mainly across portions of southeast Missouri and western Tennessee.

Whether it reaches into Kentucky and Illinois is questionable.  Instability may struggle in those areas. I will monitor it.

They did expand the dark green zone a bit farther north and east.

Here is the day one severe weather outlook.

The dark green zone is a low-level one risk.  The yellow zone is a level two risk.  The scale ranges from 1 to 5 (one being the lowest).

The light green zone is where thunderstorms are possible, but they should remain below severe levels.

.

Here is the damaging wind graphic.  The brown zone is a low risk.  The yellow zone is a slightly high-risk zone.

Damaging winds would be 60 mph winds or greater.

.

Here is the hail outlook.  Severe hail is considered to be the size of quarters or larger.  The hatched zone is where hail could be the size of half-dollars or larger.

Forecast discussion

  •   Unsettled weather today into tomorrow.
  •   There is a small risk of a few intense storms later today and tonight.  Mainly over southeast Missouri and western Tennessee.  The risk elsewhere is lower.
  •   Rainfall totals of one inch are likely across the region.  Locally higher amounts are possible.
  •   On and off cool shots into mid-May.

.

What is the primary weather concern today and tonight?

Numerous showers and scattered thunderstorms will move southeast across the entire region today. Rain chances will increase to 80–100% by this afternoon and evening, meaning most areas will see rain.

There is a small chance that a few storms could become strong or severe this afternoon or evening, but the better chances for severe weather are expected to stay south of our area.

Rainfall totals are expected to average between 0.80″ and 1.60″, although some areas could receive more.  The rain should help improve ongoing drought conditions in the region.

.

Here are the early morning current conditions.  These are the 4 AM readings.

.

Here was the 4 AM radar animation.

You can see showers and thunderstorms moving towards our region.

All of this will push across the area later today and tonight.

.


.

A cold front will move into the area later today and pass through tonight. As it gets closer, dewpoints will increase and clouds will increase.

This front will help trigger showers and thunderstorms today and tonight.

The atmosphere may not become very unstable, which could limit how strong storms become. However, because the front will arrive during the warmest part of the day, it will still need to be watched.

A few storms could become strong, but the overall risk for severe weather appears low to marginal.  Mainly across southeast Missouri and western Tennessee.  Lower chances of severe weather as you travel into Kentucky and Illinois.  I will monitor it, as always.

Widespread rain is expected today and tonight, with most areas receiving 0.80″ to 1.60″ of rain, and a few spots possibly getting more. If storms move over the same areas repeatedly, localized flooding could occur, but the overall flooding risk remains low.

Because of the clouds and rain, temperatures today will stay mostly in the 60s, which is much cooler than yesterday’s 80s. This will begin a cooler stretch of weather, with highs staying in the 60s through Wednesday. Overnight lows will drop into the 40s, which is also cooler than normal for this time of year.

Looking ahead, there is a small chance of rain Friday night into the weekend. A stronger weather system may bring better chances for rain late in the weekend and early next week.

Between these systems, temperatures should warm back up closer to normal, with highs returning to the 70s and possibly near 80° in southern areas this weekend.

Here are the anticipated rainfall totals.  As always, they will vary based on where thunderstorms occur.

Thunderstorms will enhance totals.

Looking ahead, there is a small chance of showers and thunderstorms on Friday afternoon into Friday night and a higher chance on Sunday and Monday.

The charts show several waves of below normal temperatures into the middle of May.

A bit of a roller-coaster ride in the temperature department.  Orange and red colors mean above-average temperatures.

You can see that in this animation.  The blue and purple colors represent below-average temperatures.
