Here are my current personal forecast thoughts for far southern Illinois and western Kentucky...

Monday:  Patchy morning fog possible.  Some clouds - a chance for a shower or thunderstorm.  Best chance for thunderstorms will be over our eastern and southeastern countiesA few storms could produce hail and high winds. 
Highs: 58-62 degree range then falling during the afternoon hours
Wind: West winds at 5-10 mph with gusts to 15 mph
Precipitation probability - 30%  | Rainfall totals:
  0.25" scattered - locally heavier in thunderstorms  
Confidence in this forecast is high

.
Tuesday:  Partly cloudy sky conditions
Highs:  In the 58-64 degree range

This forecast analysis covers far southern Illinois, southeast Missouri, southwest Indiana, western  Kentucky, and northwest Tennessee

HEADLINES:  A very active pattern is developing for our region.  There will be multiple chances for precipitation over the coming two week period.  


The first storm system to monitor will arrive on late Monday morning into Monday afternoon - this system will produce a few showers and thunderstorms as it strengthens and moves to the northeast.  Right now it appears that a few of the storms could produce hail and high winds - the area of concern appears to be from Evansville, Indiana towards Kentucky Lake and then eastward.  Basically the eastern counties in our region.  Monitor for updates on Monday in the event a few storms form.

Otherwise, there will be some clouds and showers and thunderstorms in our area on Monday as the system pulls through.  Main chance of precipitation would be during the late morning into the afternoon hours.

We will have a break on Tuesday.  No significant weather is expected.  We will be in between storm systems.

A powerful winter storm will develop on Wednesday and Thursday and push through our region.  We will be on the warm side of this winter storm.  That means showers and thunderstorms will likely occur.  I will need to fine tune the timing of the front.  Right now I think the best chance for showers and thunderstorms will be on Wednesday night into Thursday morning.

Right now it appears that an area of low pressure will move out of Oklahoma and into Missouri and eventually Illinois.  As this system strengthens it will pull warm/moist Gulf of Mexico air northward ahead of a strong cold front.

Showers and thunderstorms will form along and ahead of the front.  These showers and storms will move through our region starting perhaps as early as late Wednesday afternoon (western counties) and continuing chances into Thursday morning.

Wind fields will be strong with this system.  Instability may be lacking.  I can't rule out a few of the thunderstorms becoming severe.  This is especially true over our southern counties.  Monitor for updates in the event instability is strong than forecast.

If severe thunderstorms develop then the main concern would be damaging wind gusts.  Isolated tornadoes can't be ruled outAgain, monitor for updates.  The exact track of the area of low pressure will play into any threat for severe weather.

Rainfall totals on Wednesday night into Thursday morning will likely be in the 0.30"-0.60" range.  Locally heavier amounts will be possible with thunderstorms.

As the cold front passes through our region there will be colder air arriving.  Strong and gusty winds will occur along and behind the cold front.  I am expecting winds to gust in the 20-35 mph range as the system pulls away and the area of low pressure continues to deepen.  The strongest winds would likely be Wednesday night into Thursday night.  First from the south and then shifting to the west.

Several more storm systems are on the map in the long range - one around Christmas.  Monitor for updates concerning this storm, as well.

Busy busy pattern shaping up.


Monday could bring a few thunderstorms to our eastern counties.  Can't rule out a severe thunderstorm with hail and damaging winds.  Threat appears small in actual aerial coverage - but monitor for updates tomorrow morning.

I will be watching another system for Wednesday into Thursday.  The timing of the front is still in question.  I believe the best chance for showers and thunderstorms will be on Wednesday night and Thursday morning.

Monitor for updates.  There could be a few severe thunderstorms with this system.  Wind fields will be strong.  Instability is the only question that remains.


A few thunderstorms on Monday morning (late) into Monday afternoon - main concern will be over our eastern counties.  Hail and gusty winds possible with any thunderstorms that form.

Watching a bigger storm system for Wednesday into Thursday.  Gusty storms possible.  There will at least be a chance for a few severe thunderstorms - isolated tornadoes possible, as well.  Monitor for updates.

The placement of thunderstorms on Monday afternoon - right now it appears mainly along and east of a line from Evansville, Indiana to Kentucky Lake..

Remember that the National Weather Service defines a severe thunderstorm as one that produces 58 mph winds or higher, hail 1" in size or larger, and/or a tornado.   

 
Monday:  
A few thunderstorms may reach severe thunderstorms over our eastern counties - the threat appears to be for hail and damaging winds.  Monitor NWS watches and/or warnings in case they are needed No snow or ice. 

Is there a chance for thunderstorms BELOW severe limits  Yes - mainly our eastern counties (along and east of the Ohio River for the most part).

1.  Drought conditions continue over our region.  We desperately need above normal rainfall.  It does appear the next 2-3 weeks will provide some opportunity for additional rainfall.

If you are a weather enthusiast then I recommend listening to WeatherBrains each week!  For a more in-depth look at what is happening in meteorology.





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!
