HEADLINE: 
A stormy morning greeted our region.  The areas first widespread thunderstorms impacted our local states between midnight and noon.  The most intense storms were around the St Louis, Missouri area where numerous reports of hail were received.  
.
Here are some of the storm reports from the early morning storms - the blue dots are hail reports and the orange dots are wind reports.
.


.
Radar images showed the storms as they pushed through southern Indiana into southeast Missouri (these are from Tuesday morning) - click images for real size view (Gibson Ridge radar products)
.

.


.
The cold front passed through the region with a SHARP drop in temperatures during the morning and afternoon hours on Tuesday.  This ushered in a return to more seasonable temperatures.  
.
Here is the temperature map from around 9 am this morning - check out the below zero readings over the Northern Plains compared to our SIXTIES!  Click image for real size view
.


.
A weak wave will pass by our region on Wednesday night and Thursday - perhaps some clouds and maybe a flurry.  
.
Another storm system will approach our region on Friday into Friday night.  Right now it appears that there may be enough moisture to produce some rain or a mixture of precipitation (watch for updates).  There are a few data sets that show colder air with this system - I will update over the coming days if I see a shift in the storm track.

Can't rule out some flurries on Wednesday night and Thursday...

.
We will need to monitor Friday into Saturday for a mixture of precipitation - watch for updates...

Date Range: January 6th-20th
Event: Swing pattern with potential of arctic outbreaks mixed with above to well above normal temperatures - boundary near our region - uncertainty on the exact placement of the warm vs cold. Trends are towards several cold outbreaks - centered on the northern Plains into the Ohio Valley/Great Lakes. Possibly 2-3 precipitation events. Potential for 1 or 2 deep low pressure areas in the central U.S. into the Great Lakes/Ohio Valley region.
Severe Risk: Uncertain
Frozen Precipitation Risk: Possibly
Details: Potential for some significant swings in the temperature pattern.
Confidence in my forecast: Medium


.

Date Range: January 17th-February 10th
Event: Continued SWING pattern appears likely now.  Potential for 5-8 precipitation events.  NAO may move into neutral territory (MAYBE negative at times) - giving us the potential for a few wintry precipitation events.  Some data shows periods of WELL above normal temperatures.  Potential for some wild temperature swings in the coming weeks.  This could mean thunderstorms during the time period, as well.
Severe Risk: Possible thunderstorms
Frozen Precipitation Risk: Possibly
Details: Potential for some significant swings in the temperature pattern.
Confidence in my forecast:  Medium


.
. .
.
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.

-----------------------------  

.
I am adding an extended Winter STORM outlook...

.

What are the chances for a winter STORM event (see definition below - this DOES NOT include chances for light winter precipitation - this is for winter STORMS) over southeast Missouri, southern Illinois, southwest Indiana, western Kentucky, northeast Arkansas, or northwest Tennessee?   
.
Winter STORM would be the potential for snow accumulating to 2" or more - icy travel conditions with enough sleet or freezing rain to cause advisories and/or winter storm watches/warnings to be issued by the National Weather Service. 

.
Keep in mind that the percentages DO NOT mean that is what will actually fall from the sky.  It is the potential of a winter storm developing and impacting our region.  The ACTUAL forecast snowfall or ice totals are only issued in the SHORT range discussion (top of the blog page).
.   

Wednesday the 18th - 0% 
Thursday - 0%
Friday - 5%
Saturday - 5% 
Sunday - 0%
Monday - 0% 
Tuesday the 24th - 0%
.
1. No major changes in the long range outlook.  A weak system on Friday into Saturday could bring some light precipitation.  Another rain producer appears likely towards early next week - perhaps Tuesday or so.  Models are not in good agreement on exact timing.  Appears warm enough for rain and perhaps some thunderstorms.
.
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!
