Rain is the concern.  Some heavy rain over the coming days.  Watch for ponding of water on roadways.  A flash flood watch has been issued for some of our counties - see below.
.

.
Avoided roadways with water over them
.

The wild card in this forecast will be how much rain falls between now and Tuesday night.  Right now thinking most counties pick up 1.5-3" with locally heavier amounts.  Some counties may pick up more than 5 inches of rain.

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!

.
Here comes the rain again.
.
Periods of showers and thunderstorms will be possible - beginning tonight (Saturday night) and continuing right on into Tuesday afternoon.
.
The rain will arrive in waves.  It won't rain all of the time.  There is a flash flood watch for portions of southern Missouri, northeast Arkansas, and western Tennessee.
.
Here is the graphical outline of the flood watch - in green
.


.
Most areas are going to pick up between 1.5-3" of rain between now and Tuesday afternoon.  There will be pockets of 3-6" of rain.  The exact placement of the heavier rain bands is still a bit uncertain.  Part of this depends on the track of the area of low pressure - which has been shifting northward over the last 24 hours.
.
There will be a chance for lightning and thunder.  Severe weather risk appears very low.  Will monitor for any changes. If severe weather were to pop up then it would likely be late Monday night and Tuesday.  Watch for updates.
.
Bottom line - rain and plenty of it in the coming days.  Some ponding of water will be possible on roadways - flash flooding could occur in a few counties.  More concern will be low lying areas that are prone to flooding - poor drainage areas - areas where leaves are clogging up drains.  Significant rises are possible are small streams and creeks.  
.
Rises on the Ohio River will likely be in the 6'-10' range.  However, this will still be below flood stage.

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 Saturday into Sunday.  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!
