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



Tuesday night:  Partly cloudy and warm. 
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 - 10%   | Rainfall totals:  0
Confidence in this forecast is very high
.
Wednesday:  Warm and humid - windy  - a mix of sun and clouds.  A chance for a popup shower or thunderstorm.
Above normal temperatures
Highs:  around middle to upper 80s degrees.  | Normal highs for this time of the year are around 75 degrees.
Wind: Southwest winds at 15-25 mph - gusts will be over 30 mph - boaters use care on lakes and rivers
Precipitation probability - 10%  Rainfall totals:   Most areas will remain dry
Confidence in this forecast is very high

.
Wednesday night:  Mostly clear skies.  Warm.
Above normal temperatures
Lows: in the upper 60s |  Normal lows for this time of the year are around 52 degrees.

Boaters:  Winds each day - into Friday - will gust above 25 mph - boaters use care.


.

.


Boaters use caution with gusty winds

.


The wild card in this forecast is whether or not a few counties might hit 90 degrees over the next couple of days - either way it is going to be very warm.


We should be mostly capped on Wednesday and Thursday - that means it will be difficult for thunderstorms to form.  Can't rule out a stray - but it appears better chances will arrive on Friday into Monday (for thunderstorms).

HEADLINES:  
WELCOME TO SUMMER!!  

Very warm temperatures for this time of the year will continue over the coming days.  Along with the warm weather will come strong winds from the south/southwest - winds will be in the 15-25 mph range during the daytime with gusts above 30 mph.  Boaters should use care on area lakes and rivers.

Isolated thunderstorms may once again form this afternoon (Tuesday and Tuesday evening) - especially over parts of Illinois and Indiana - northwest Kentucky.  If storms do form then they could produce large hail and high winds - isolated tornado possible.

Radars - click here
Watches/warnings - click here


Rain chances will be less over the next two days (Wednesday/Thursday) than recent days.  We may see activity pick back up on Friday into Monday.  Some storms could be heavy.  

We will monitor the severe weather threat.  Instability will be high on Friday into Sunday - can't rule out some severe storms.  Heavy rain and lightning may be the primary concern (but with this type of atmosphere it will need to be monitored).


Here are the temperatures for the next few days - very warm for this time of the year.  Our weird year of weather continues unabated.  


Check out the extended part of the forecast - some UGLY dew point temperatures being forecast for the region - it will feel more like Louisiana around here than southern Illinois and western Kentucky.


Low temperatures for Tuesday morning followed by Wednesday afternoon highs (it will be quite warm)


Here are the Wednesday morning lows (below) - followed by the highs on Thursday


Here are the Friday morning lows and the Friday afternoon high temperatures



Heat index values for Wednesday - the high dew points will make it feel muggy outside 


Here are the departures - below - look at just how MUCH ABOVE normal temperatures will be.





We have a TON of new weather maps on the Weather Observatory web-site - these include temperatures, wind speed, dew points, heat index, barometric pressure, predicted rainfall, climate forecast, medium and long range maps, forecasts and more!  Click here

We have a number of new radars available on our Weather Observatory web-site!

We now offer St Louis, Mt Vernon, Evansville, Poplar Bluff, Cape Girardeau, Marion, Paducah, Hopkinsville, and Dyersburg Interactive City Radars.  We also have the two regional radars and now offer you three GR Earth radars.

Let's check out the how much rain is forecast to fall over the next 48 hours.  This map gives you a general broad brushed idea of what can be expected.  Remember the scale is at the top of the map.

Storms will be SCATTERED the rest of this afternoon and Wednesday - this map is probably overdone as MOST areas will remain dry.  Better chances of rain as we move towards Friday into Monday.  Keep that in mind.

You can also now view the probability of X amount of rain (you pick the value on the web-site) in a six hour period of time.  Those maps can be viewed here.

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.  Unsettled pattern will redevelop on Friday into Monday (perhaps into the middle of next week) - it appears we may have additional shower and thunderstorm chances in the area.  Some storms will be heavy.


Check out the CAPE values on Friday into the weekend - lot of energy in the atmosphere.  Low of moisture in the atmosphere.  This leads me to believe that there could be some thunderstorm complexes form at night.  These typically produce a lot of lightning and heavy rain.  The exact track of the complexes will have to be monitored as we push into the weekend - keep that in mind, though, if you have outdoor plans.


Don't cancel any plans - just monitor for updates.


Here are the CAPE values - remember CAPE is basically energy in the atmosphere that storms can tap into.

Friday - Saturday - Sunday maps. 



Now check out these ugly dew point maps - remember that once we hit 60 degrees the air mass starts to feel a bit humid - once you reach 70 we are talking about, as Jim Rasor would say, AIR YOU WEAR.  Muggy conditions in the coming days.  

Here are the dew point maps

Here is Friday evening




Saturday




Sunday - moist air mass

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!
