Winter Storm arriving Dec 26?

It was December the 20th, and on this date, the NWS was beginning to take notice of a very large and intense low pressure system that was currently located off in the Pacific. No one was sure, at the time, as to the track or impact that this system might have on Midwestern states around December the 26th! At the time, all three computer models were in agreement that there was going to be some sort of weather related impact! I planned to track the progress of this low to see what it does...

Dec 20 - While it was windy in the center part of the Midwest,  low pressure system was still slowly approaching the West Coast on Thursday.

 Dec 21 - There was still a large amount of uncertainty as the the track of this large storm. On model, the GFS (Global Forecast System - One of the operational forecast models run at NCEP. The GFS is run four times daily, with forecast output out to 384 hours) sees the system running a southerly track while the ECMWF (European Center for Medium-Range Weather Forecasts - Operational references in forecast discussions typically refer to the ECMWF's medium-range numerical forecast model, which runs out to 10 days) is calling for a more northerly run. We could see rain with one and snow with the other. Stay turned.

Monster winter storm targets the Midwest!

Fictional Account: In what has now been termed the Storm of the Century, a number of factors came together to result in the stranding of tens of thousands of Missouri residents!

On the evening of December the 17th, a low pressure system transited across the gulf states throwing up moisture laden air into the center of the United States. This air slammed into a arctic vortex that barreled down from northern Canada. Boasting temperatures in the low teens, the super chilled air travel quickly over a fresh snow pack that cover the northern tier of states. These two forces coming together, resulted in hurricane force winds that carried a mixture of sleet and snow. Before the dawn of the next day, snow amounts were in excess of 13 inches in some locales with eight foot drifts that closed many key arteries. Power outages were widespread.

In the southwest portion of the state, cities like Branson were also treated to a horrific ice storm that coated trees, bridges and power cables. Reports of downed power lines were so numerous, that a State of Emergency was announced by the Governor's Office. Thousands were without power and also could not travel due to treacherous road conditions as of Tuesday, December 18. The National Weather Service then announced the approach of an even larger system that was forecast to arrive over the weekend.

While this piece was just a flight of fancy, such a storm could happen sometime in the future. Everyone, then, should take sensible steps to insure they have some of the following:

Have a Weather radio on hand that is turned on all the time.
Have enough food to last at least a week.
Have an auxiliary source of heat or generator.
Get a check up for your vehicle or vehicles. Be winter ready!
Have a get out of Dodge plan to move out of a severe winter storms path.
