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


Sunday night:  Foggy at times.  A chance for some showers and thunderstorms.  More widespread after midnight and into the morning hours. 
Above normal temperatures.
Lows:  in the 48-55 degree range with colder temperatures the further north and west you go in the region |  Normal lows for this time of the year are around 39 degrees.
Wind:  Easterly winds at 5-10 mph - gusts to 15 mph.  
Precipitation probability - 70%  | Rainfall totals:  0.30"-0.60" locally higher amounts possible
Confidence in this forecast is high
.
Monday:  Dense fog.  Mostly cloudy with showers and thunderstorms from time to time.  Mild.   
Above normal temperatures.
Highs:  around 65-68 degrees over the southern counties and in the upper 50s to lower 60s over the far western and northern counties.  | Normal highs for this time of the year are around 59 degrees.

.
Monday night:  Dense fog early in the night.  Showers and thunderstorms becoming likely. Windy at times.  Locally heavy rain possible.

Rain and quite a bit of it over the coming days.  Can't rule out some low land flooding or poor drainage areas.  Also carefully monitoring Tuesday for strong thunderstorms - isolated severe storms.  Dense fog.
.

.
Avoided roadways with water over them.  Also dense fog is a concern.
.

The wild card in this forecast will be when the rain ends on Tuesday.  Right now it appears there will be some thunderstorm chances into the late morning or early afternoon hours over far southern IL and western KY - then coming to an end from west to east during the afternoon.

The forecast for severe or extreme weather for the next 24 hours

.
The McCracken County Office of Emergency Management reminds you that owning a NOAA All Hazards Weather Radio is the best way to receive notifications of severe weather watches and warnings.
.
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.  More information with some slides concerning reporting severe weather - click here

HEADLINE:  Don't forget WINTER WEATHER PREPAREDNESS WEEK HAS ARRIVED - CLICK HERE FOR MORE INFORMATION!

.
Rain spread over the region on Saturday night and Sunday morning.  Rainfall totals of 0.30-3.00" have been reported over the area.
.
The heaviest rainfall fell over parts of the southwest Kentucky towards Kentucky Lake and then east/northeast of there.  2-3" of rain was reported by spotters.  Some flooded creeks have been observed.
.
Rain will continue on and off until the entire system moves east later on Tuesday.
.
There could be a few severe thunderstorms on Tuesday - there is some question on instability.  There are also questions on timing.  If the system pushes east during the morning hours then the threat for severe weather will be diminished.  If it slows by six to eight hours then the risk is a bit greater.  This will need to be monitored.
.
Thanksgiving will be DRY and cool.  Black Friday will be DRY and cool.  RAIN enters the forecast later on Friday night into Saturday night.

Date Range:  November 26th 
Event:  Showers and some thunderstorms - locally heavy rain possible.
Severe Risk: Too soon to make a forecast on severe weather - locally heavy rain is possible
Frozen Precipitation Risk:
Details:  Another in a series of storm systems will impact our region.  Cold front with showers and thunderstorms - colder air behind the system.  Rain may start as early as Friday night.
Confidence in my forecastVery high

.

Date Range:  November 27th -November 31st
Event:  Below normal temperatures.
Severe Risk:
Frozen Precipitation Risk:  Possible event towards the very end of the month - highly uncertain
Details:  Colder air arrives behind our holiday weekend storm. 
Confidence in my forecastHigh

.
Date Range:  December 1st - December 12th
Event:  Mostly below normal temperatures.  Active pattern.
Severe Risk:
Frozen Precipitation Risk:  Possible the first few days of the month
Details:  Cold air - several shots of below normal temperatures.
Confidence in my forecast:  Medium

.
.


Date Range:  December 7th-10th
Event:  Near normal to below normal temperatures.
Severe Risk:  
Frozen Precipitation Risk:  Possible
Details:  Potential precipitation event.
Confidence in my forecast:  Low

.
.
Date Range:  December 27th-30th
Event:  Significant storm system in the Missouri/Ohio/Tennessee Valley
Severe Risk:  
Frozen Precipitation Risk
Details:  Potential precipitation event.
Confidence in my forecast:  Low
.
.
Remember that as a general policy, in the long range outlook, I will NOT mention severe thunderstorms more than 72 hours in advance.  I will mention thunderstorm risks and I will give as many details as possible.  The word severe will be reserved for the short range forecast.

-----------------------------  
.
1.  Long range is unfolding about as expected.  The last half of the month was supposed to bring well above normal rainfall with an active pattern.  Also cold air was forecast to arrive towards the end of the month and into December - with the potential for below normal temperatures.
.

I will be watching several precipitation chances the first 2 weeks of December and a possible significant storm system towards the end of December.  Lot of cold air is building - this will likely be a dramatic switch from Novembers weather.

.

Our next widespread rain event is still on schedule for the holiday weekend - most likely late Friday night into Saturday/Saturday night.  Rainfall totals of 1-2" will be possible with this system.  Some thunderstorms are also possible.  Colder air behind the storm for Sunday into the following week.
.

November is looking as if it will be a bit of a roller coaster in the temperature department - if we do end up with several deep storm systems then we would experience warm air moving up ahead of the storms and then cold air behind the systems.  Analogs are showing a cold to very cold December into  February - with a cooler than average spring and stormy/wet spring. The cold air this winter will depend on the blocking - more blocking = colder weather.
.
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!
