Here are my current personal forecast thoughts for far southern Illinois and western Kentucky...
.
Sunday night:  Mostly cloudy skies.  A few evening showers/storms - mainly northern counties
Above normal temperatures
Lows: in the lower 60s  |  Normal lows for this time of the year are around 52 degrees.
Wind:  Southwest winds at 5-10 mph.  
Precipitation probability - 20%   | Rainfall totals:  0.25"
Confidence in this forecast is very high
.
Monday:  A mix of sun and clouds.  A chance for showers and thunderstorms - some storms could be severe.  Again - not everyone will pick up rain.
Above normal temperatures
Highs:  around 78-84 degrees.  | Normal highs for this time of the year are around 75 degrees.
Wind: Southwest winds at 10-15 mph
Precipitation probability - 70%  Rainfall totals:   0.25" with locally heavier amounts in storms.
Confidence in this forecast is medium

.
Monday night:  Partly cloudy skies.  A chance for a shower or thunderstorm.
Above normal temperatures
Lows: in the lower 60s |  Normal lows for this time of the year are around 52 degrees.
Wind:  Southwest at 5-10 mph
Precipitation probability - 70%  Rainfall totals:
0.25" with locally heavier amounts in storms.
Confidence in this forecast is medium
.
Tuesday:  Partly cloudy skies - a chance for showers and thunderstorms.  
Above normal temperatures
Highs:  around 80 degrees | Normal highs for this time of the year are around 75 degrees.

Concerns will remain the same over the coming days - some areas will pick up thunderstorms - large hail and gusty winds - lightning.  Other areas will remain dry - right now it appears our northern counties will be the most likely areas impacted by storms.  With this type of pattern you can expect conditions will vary greatly over the region - keep this in mind.



Best advice check radar to see where storms are forming.  Listen to weather radios if storms threaten - or local media.
.

.
If you have outdoor plans then monitor radars

.



The wild card in the forecast will remain the same as recent days - the placement of showers and thunderstorms



If you have outdoor plans then monitor radars.

This forecast analysis covers far southern Illinois, southeast Missouri, southwest Indiana, western Kentucky, and northwest Tennessee
.
HEADLINES:  
An incredible and devastating hail event smashed through parts of eastern Missouri and southern Illinois on Saturday afternoon.  Numerous reports of golf ball to soft ball size hail were received around the St Louis area - many counties surrounding St Louis, as well.  


Damage will likely run well into the tens of millions of dollars and perhaps hundreds of millions of dollars.  This was one of the more destructive hail storms in the history of St Louis, Missouri - it will likely rank  in the top three.  It will take some time to pull all of the numbers together.


Over 100 people were injured in St Louis when a tent collapsed - 1 person died of a possible heart attack.


Some of our counties were impacted by hail storms - mainly northern counties.  Thankfully, as expected, the cap held over much of the region.


It has been feast or famine with thunderstorms lately - some areas picking up large hail and very heavy rain and other areas remaining bone dry.  This pattern will likely continue over the next few days.


Any storms that form this week could produce heavy rain, hail, gusty winds, and frequent lightning.  The tornado threat appears low.

Officially we are in a risk zone for parts of the area on Monday - now this may shift around a bit - check the Beau Dodson Weather Facebook page for updates

The orange area is the slight risk zone - the yellow area is the general thunderstorm area




Monitor updates throughout the week as each event unfolds.  

Here are the Monday morning lows followed by the Monday afternoon high temperatures


Here are the Tuesday morning lows and Tuesday afternoon highs




It will be quite humid from time to time - making it feel more like summer.




This is what the big hail storm looked like on satellite yesterday - very high cloud tops.  Click to view real size.

Remember that as a general policy, in the long range outlook, I try not to mention severe thunderstorms more than 72 hours in advance (unless the signal is so overwhelmingly convincing that it warrants a mention).  I will mention thunderstorm risks and I will give as many details as possible.  Also remember you can view the long range severe weather outlooks by visiting the Storm Prediction Center's web-site - click here

1.  Short discussion today - we have been upgrading and cleaning equipment.


Unsettled weather Monday into Tuesday - again on Thursday into Friday - hopefully we all pick up a little bit of rain.  It would be nice.  We need rain - the ground is dry.


Here is the latest six to ten day temperature outlook - we are being placed in above normal.

Seasonal outlooks can be viewed on the web-site - click here

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!
