Here are my current personal forecast thoughts for far southern Illinois and western Kentucky...
.
Thursday night:  Partly cloudy.  Cooler.  A chance for an evening shower or thunderstorm - mainly in Kentucky and Tennessee - a few storms could be severe.  Latest watches and warnings - click here
Near normal temperatures
Lows: in the upper 40s and lower 50s  |  Normal lows for this time of the year are around 50 degrees.
Wind:  Northeast winds at 5-10 mph.  
Precipitation probability - 30%   | Rainfall totals:  0.25" in areas that receive rain - locally higher
Confidence in this forecast is very high
.
Friday:  Partly cloudy with a chance for showers and thunderstorms.
Near normal temperatures
Highs:  around 70 degrees.  | Normal highs for this time of the year are around 72 degrees.
Wind: East winds at 10-15 mph
Precipitation probability - 30%  Rainfall totals:  
0.25" with locally heavier amounts in thunderstorms  Confidence in this forecast is high
.
Friday night:  Partly cloudy skies.  A chance for a shower or thunderstorm.
Above normal temperatures
Lows: in the lower 60s  temperatures will vary quite a bit over the region as a whole because of the frontal system near our local counties |  Normal lows for this time of the year are around 50 degrees.
Wind:  Southerly winds at 5-10 mph
Precipitation probability - 20%  Rainfall totals: 0.25"
Confidence in this forecast is medium
.
Saturday:  Partly cloudy - warm - a chance for thunderstorms - a few storms could be on the heavy side.  
Above normal temperatures
Highs:  around 75-80 degrees | Normal highs for this time of the year are around 72 degrees.
Wind: Southwest at 5-15 mph - gusty at times 
Precipitation probability - 60%  Rainfall totals:  0.25"-0.50" with locally heavier amounts in thunderstorms 
Confidence in this forecast is medium

A chance for heavy storms this evening near the KY/TN border counties.  A few severe.


The next shot at thunderstorms for most of the area will be on Friday and again Saturday.  

BOTTOM LINE - don't cancel any plans over the coming days - simply be weather aware and check the latest forecast and radars if you have outdoor plans!
.

.
Monitor radars if you have outdoor events this evening and on Friday and Saturday.  Thunderstorms will be possible. 


BOTTOM LINE - don't cancel any plans over the coming days - simply be weather aware and check the latest forecast and radars if you have outdoor plans! 

.


Once again the wild card is going to be just how widespread precipitation will be on both Friday and Saturday.  We have had several rounds of precipitation over the last couple of days - some areas did not pick up much in the way of measurable precipitation.  It does appear we have a better chance for widespread shower and thunderstorm activity on Friday and Saturday - most likely the best chance of the whole week.




BOTTOM LINE - don't cancel any plans over the coming days - simply be weather aware and check the latest forecast and radars if you have outdoor plans!

This forecast analysis covers far southern Illinois, southeast Missouri, southwest Indiana, western Kentucky, and northwest Tennessee
.
HEADLINES:  
A band of severe thunderstorms pushed through portions of our region late Wednesday night and early Thursday morning - mainly impacting parts of southeast Illinois into southern Indiana and then down into parts of Kentucky.


Most areas remained dry.  If you have not received any rain over the last 48 hours - don't shoot the messenger.  I told you it would be a complicated forecast this week with many people seeing no rain at all - while others pick up quite a bit!  That is exactly how it has played out.  


Some of us have only picked up enough precipitation to pepper the car with raindrops - me being one of them!  We need more rain.

This evening will be dry over most of the area - the exception will be along the KY/TN border counties where a band of heavy storms will develop and push southward.  A few of the storms will be severe with hail and gusty winds. Latest watches and warnings - click here


There will be another chance for rain/storms on Friday and Saturday - hopefully more of us pick up some much needed rain.  


Can't 100% rule out a severe thunderstorm - especially on Saturday.  Right now it does not look like widespread severe weather.  I will monitor, as always.


Unsettled weather will continue into next week with several disturbances moving through the flow.  This will mean additional rain chances and thunderstorm chances. 


Let's take a look at the WIDE range of temperatures over the coming day - can you find the front?   Temperatures will vary quite a bit in the coming days - northern areas much cooler than southern areas.  The front will be the dividing line.

In order - first will be Thursday night lows - then Friday highs - then Friday night lows - then Saturday highs - then Saturday night low - then Sunday high temperatures!



Here are three videos put together by the Huntsville, NWS Office concerning last years super tornado outbreak.  This gives you a good idea as to what the NWS goes through during an outbreak.

Feast or famine.

Now is a GREAT time to buy a NOAA All Hazards Weather Radio.  Better to have one before storms strike than to be without one during an event.  I recommend the Midland Model 300 NOAA All Hazards Weather Radio - that is what I use here at my house!
