HEADLINE: Saturday brought a FROSTY morning to our region - a few patches of freezing fog were also noted near area lakes and rivers.

.
Sunday will be dry - milder with highs into the 50s.  Not too bad for the middle of December - that will be above normal in the temperature department.
.
The next chance of rain arrives on Monday and will last into at least Tuesday night or Wednesday.  Some disagreement on when the rain exits the region.  It also may end as a light mix over the northern portions of our region. 
.
A MAJOR winter storm is forecast over the next few days across portions of Oklahoma, Kansas, and into Missouri.  Several inches of wind driver snow will fall in those states. 
.
Precipitation maps for the next few days - first map is Sunday - then Monday-Wednesday.

.
The probabilities forecast for this next rain event.  The explanation for each probability can be found next to the numbers.  I am not a fan of probabilities - however, they do serve a purpose for those interested.
.
Probabilities for rainfall totals - Monday through Wednesday - entire event

There will be a 100% chance of 0.20-0.50" of rain falling - certain chance - an ten out of ten chance
There will be a 90% chance of 0.50-0.75" of rain falling - good chance of occurring - a nine out of ten chance
There will be a 60% chance of 0.75-1.00" of rain falling - medium chance of occurring- a six out of ten chance

There will be a 40% chance of 1.00-1.50" of rain falling - a chance of occurring - a four out of ten chance
There will be a 10% chance of 1.50-2.50" of rain falling  - a one out of ten chance

Date Range:  December 18th - December 22nd
Event:  Precipitation events
Severe Risk:  
Frozen Precipitation Risk
Details:  A more significant storm system possible in or near our region.  A mix of above and below normal temperatures.  Rainfall of 0.40-0.80" possible with the Monday/Tuesday system - another chance for precipitation around Thursday/Friday
Confidence in my forecast.   Very High
.
.

Event:  Significant storm system in the Missouri/Ohio/Tennessee Valley - more below normal temperatures days vs above normal days. 
Severe Risk:  
Frozen Precipitation Risk
Details:  Potential precipitation events.
Confidence in my forecast:  Medium
.
.
Date Range:  December 26th-January 15th
Event:  Potential for bitterly cold air masses mixed in with above normal temperatures
Severe Risk:  
Frozen Precipitation Risk:  3-5 potential precipitation events
Details:  Potential precipitation event and perhaps below normal temperatures.  Uncertainty surrounds the NAO going negative - some blocking in the Atlantic.
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.  Shorter update today - no big changes in the long range.  
.
Will be watching one system for Thursday/Friday - still a bit iffy on the details on that system.  
.
I continue to monitor the potential for precipitation on Saturday/Sunday of next week.  EC model says not going to happen - GFS says maybe.  This run of the GFS is a bit warm and would indicate rain for Christmas Day.
.
The majority of ensemble model runs are showing dry weather here for Christmas weekend.  This is a fast flow atmosphere - disturbances seems to be moving through our region every few days - I won't rule out precipitation Christmas weekend just yet.
.
Some NWS offices are now saying Christmas weekend will be dry - other offices are saying they just are not sure yet.  Guess we will continue to monitor and update in the coming days!
.
Here are the GFS maps from www.wright-weather.com
.

.
.
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!
