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.

Friday through Friday

1.  Is lightning in the forecast?  Yes.   Isolated storms today into Saturday.  Most areas will remain dry.  A better chance of lightning late Saturday night into Sunday.  The risk of lightning Monday through next Friday appears to be low.  Monitor.

2.  Are severe thunderstorms in the forecast?  Low risk.   The main concern will be down burst wind.  Thunderstorms, during the summer months, can grow to 40,000 to 55,000′.  When they weaken they can collapse.  This causes high winds.  Winds can exceed 50 mph.

* 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? Possible.  Slow moving storms will produce heavy rain.  Pockets of flash flooding may occur.

4.  Will there be a chance of a frost or freeze?  No.

5.  Will the heat index exceed 100 degrees?  Yes.  Heat index values from 100 to 105 are likely outside of cloudy areas.

6.  Will the wet-bulb globe temperature reach caution or danger levels?  Yes.

Friday WBGT (F): 83° Take 15 minute breaks each hour of working or exercising in direct sunlight.
Saturday WBGT (F): 83° Take 15 minute breaks each hour of working or exercising in direct sunlight.
Sunday WBGT (F): 83° Take 15 minute breaks each hour of working or exercising in direct sunlight.
Monday WBGT (F): 83° Take 15 minute breaks each hour of working or exercising in direct sunlight.
Tuesday WBGT (F): 84° Take 15 minute breaks each hour of working or exercising in direct sunlight.
Wednesday WBGT (F): 85° Take 15 minute breaks each hour of working or exercising in direct sunlight.

.

The WetBulb Globe Temperature (WBGT) is a measure of the heat stress in direct sunlight, which takes into account: temperature, humidity, wind speed, sun angle and cloud cover (solar radiation).

This differs from the heat index, which takes into consideration temperature and humidity and is calculated for shady areas.

If you work or exercise in direct sunlight, this is a good element to monitor.

Sports coaches, schools, military agencies, OSHA, and many nations use the WBGT as a guide to managing workload in direct sunlight.

Today through July 14th:  Thunderstorms over the coming days could produce isolated wind damage.  Torrential downpours and nickel size hail, as well.  Lightning will be a concern for those outside.  There is a low-end risk of severe thunderstorms.  This chance increases if we can get a complex of thunderstorm (an MCS) to form.

 

 

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.

Weather advice:

Updated July 10, 2020

Scattered thunderstorms over the coming days will produce downpours, gusty wind, and lightning.  Monitor the radars if you have outdoor events.

Lightning is always a concern for those outside, boating, or other.  Head indoors if thunder roars.

Heat index values today through Sunday will rise into the 95 to 100 degree range.  Locally higher numbers. Muggy weather.  Use care, as always.

Don’t leave pets, children, or adults in hot cars.  Cars can rapidly heat to above 115 degrees in this kind of weather.  Use common sense, as always.

Weather Discussion

    1.   More heat and humidity.
    2.   Monitoring thunderstorm chances.
    3.   Heat-wave next week.

 

Good day, everyone.

The heat and humidity will continue.  Our only real break will come when clouds thicken and some thunderstorms form.  Otherwise, hot and muggy weather through next week.

I am carefully monitoring the chance of MCS’s.  MCS’s are thunderstorm complexes.  They are normal during the summer months and provide much of our rainfall from June through August.

These MCS’s often times move into our region from the northwest.

We have two or three chances of a thunderstorm complex either hitting our region or clipping it.

One of those will occur tonight.  That one would clip southeast Missouri.  Most likely dry, elsewhere.

We have another chance Saturday night and Sunday.

Highs today through Sunday will be in the lower 90s.  If clouds are thicker then highs will only reach into the middle to upper 80s.  Overnight lows will dip into the 70s.

Heat index values, outside of thicker areas of clouds, will range from 94 to 98 with pockets of 100 to 105 degrees.  Not all that comfortable.  Muggy.

It appears that temperatures will rise next week and we may be dealing with highs in the middle and upper 90s.  That means heat index values of 100 to 110.  A heat advisory may be issued next week.  Repeated days in the 90s will take a toll on those susceptible to hot weather.

Not all that great of a forecast for those who do not love hot and muggy weather.

Monday through Friday of next week will be hot and humid.  Daily highs in the 90s and overnight lows in the 70s.

At this time, it appears that it will be dry.  A few days towards the middle and end of the week could reach into the upper 90s.

Heat index values will top 100 degrees each day.  July weather!

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.

.

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.
