This forecast covers far southern Illinois, southeast Missouri, southwest Indiana, western Kentucky, and northwest Tennessee - for your local town/area - click here
.
Here are my current personal forecast thoughts for far southern Illinois and western Kentucky...
.
Wednesday night:  A few clouds.  Slight chance for a shower/sprinkle over the north/northeast part of the area.  Near normal temperatures.
Lows:  in the 54-58 degree range.  |  Wind: Southerly winds at 5-10 mph.  Normal lows for this time of the year are around 54 degrees.  Precipitation probability - 10%
.
Thursday:  A mix of sun and clouds as the upper level low spins to our north - warm - a slight chance for a shower/thunderstorm - mostly in Indiana.  Above normal temperatures.
Highs:  in the 80-85 degree range.  |  Wind:  West winds at 5-10 mph.  Normal highs for this time of the year are around 78 degreesPrecipitation probability - 10%
.
Thursday night:  Partly cloudy with a slight chance for a line of thunderstorms - mainly, again, over the north and east part of the region - closer to the IL/KY/IN state line.  Turning cooler.  Below normal temperatures.
Lows: around 44-48 degrees  |  Wind:  West winds at 5-10 mph becoming northwest at 10-15 mph with higher gusts at times. Normal lows for this time of the year are around 54 degrees.  Precipitation probability - 10%.
.
Friday: A few clouds.  Cooler - windy at times.  Below normal temperatures.
Highs:  around 64-68 degrees. |  Wind: West/northwest winds at 10-20 mph - gusty..  Normal highs for this time of the year are around 78 degrees.   Precipitation probability - 0%
.

.
.
Added the chance for a thunderstorm line over our northeast counties on Thursday evening into Thursday night.  This will be along a strong cold front.  Tweaked winds - winds will be gusty on Thursday night and Friday.  Video's are being posted again (each morning - blog is evening and video is morning)

Wednesday night:
  Severe weather is not anticipated.
.
Thursday:  Severe weather is not anticipated.
.
Thursday night:
  Severe weather is not anticipated.A line of thunderstorms will be possible moving out of central Illinois and Indiana - moving southeast into parts of southern IL into southern IN and northern Kentucky.  A bit unsure how far southwest this line will form.  Will update accordingly.  Severe weather is not expected - storms could produce gusty winds and perhaps small hail.
.
Friday:   Severe weather is not anticipated

HEADLINE:  A strong cold front will move through the area on Thursday night and Friday.  Along and ahead of this cold front will be a line of thunderstorms on Thursday evening.  This line will form from Indiana down into Illinois and then move southeast towards southern IL and southern IN.  The line should hold together over parts of Kentucky.  I am a bit unsure just how far southwest the line will develop.  It may stay just northeast of Marion - Metropolis - Paducah.  Will monitor.
.
Here is one of the maps from the Weather Observatory web-site showing you the approximate placement of the rain chances.  Again - this could be off by a few counties either direction.  But this does give you a general idea.
.
.
Here is what one meso-model is showing for Thursday afternoon/evening.  You can see the line of thunderstorms along the cold front.  This is what the model "thinks" the radar will look like tomorrow afternoon/evening.  Again - this is just one models forecast idea.  Which does make sense - the cold front is fairly potent.  There should be enough lift to spark at least a small band of storms along and ahead of it. 
.
.
Here is another view from a different model - from www.wright-weather.com - it also shows a band of thunderstorms but not as far south and west as the other model run.  Will keep an eye on it - not overly concerned and not expecting severe weather in our counties.
.
.

.
The next big story will be the cold front itself.  Gusty winds and much cooler temperatures will sweep into the area on Thursday night and Friday.  This cooler weather will continue into the weekend.  Lows will be in the 40s on Friday morning into Monday morning - perhaps some 30s in isolated spots.  High temperatures will be in the 60s on Friday and Saturday and perhaps touch 70 on Sunday.  Fallish?  Perhaps a bit!
.
Winds will be gusty at times on Thursday night and Friday.  Would not be surprised to see some 30 mph gusts behind the cold front.  If you are boating then use caution.
.

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

The McCracken County Office of Emergency Management reminds you that owning a NOAA Weather Radio is the best way to receive notifications of severe weather watches and warnings.

.
.
.
Be aware that there may be a line of storms on Thursday evening/night over the northeast part of our region.  Otherwise gusty winds would be a concern on Thursday night and Friday.  A dry and cool weekend ahead of us.  Enjoy!

Drought continues across a large chunk of real estate.  This has been a concern for quite some time now.  Droughts tend to creep.  Many of you have witnessed the extreme fire conditions over portions of Texas and Oklahoma on the different news outlets.  I have been watching this drought slowly creep north and east over the last few months.  This will need to be monitored as we move into the fall and winter months.
.
Here is the latest soil moisture capacity map.  Severe drought continues over Texas, Oklahoma, Louisiana, and parts of Arkansas.  The areas in green are moist regions - the areas in orange and yellow are in need of rain.  The recent rains in our area have helped our cause to push back the drought to our south and west.

1.  The big story of the week continues to be the Canadian High Pressure that will move into the Ohio Valley this weekend.  This will help usher in some cool air for Saturday and Sunday.  Highs may struggle to reach 70 degrees.  Lows will likely dip into the 40s.  Not bad for the end of September.  I guess this will put everyone in a fall mood. 
.
Here is the latest six to ten day outlook for temperatures.  Normal to below normal temperatures will continue for our area - check out the forecast for above normal temperatures to our west.
.
.
We normally see an uptick during the fall months - will keep an eye.  Don't forget that September is preparedness month.  For more information on the different types of severe weather that can impact our region - click here.
.
Now is a GREAT time to buy a NOAA Weather Radio.  Better to have one before storms strike than to be without one during an event.
