Major Snow/Ice Storm With 2-3 Days Below Freezing In Dallas, OKC To Go Sub 0

Written by on December 5, 2013 in United States of America with 0 Comments

It’s brutal already from Edmonton down to Denver and the arctic air continues to bleed south into Texas, setting the stage for a wild and rough next 90-hour period from the Southern Plains up through the Ohio Valley. It’s already around -20° at this hour over Wyoming and it will grow colder in the coming days with Friday temps failing widely to even make -10 across Montana, Wyoming into the Dakotas.

We have an increasingly significant ice event on the way from the heart of Texas up through Dallas, TX and the way northeast to Columbus, OH as low pressure forms on the southern boundary of the arctic air mass and draws warm, moist air from the Gulf which will ride up and over the shallow layer of cold air right near the ground. There will be a band which contains heavy, potentially flooding rainfall on the southern edge, heavy snow which totals up to a foot on the northern edge and in between, ICE will become a significant problem Thursday through Friday.

While the cold is impressive across the North down into the heart of the nation late this week, the upcoming 5-10 day period in Dallas could be very rare indeed as modelling shows several days stuck below freezing with nights tanking, perhaps down to 10° late weekend. Further west from Lubbock up into the OK Panhandle we could see many days in the 10s and it goes below 0 by night, especially with fresh snow cover.

Check out the mess coming up via TWC.

Keep in mind that snow as well as freezing rain is possible in and around Dallas and temperatures by Friday and through this weekend are likely to stay at or below freezing. Sustained periods of time without power and with this rare cold, will be a dangerous combination for sure. There’s also little or no road salt down here, so roads could be significantly ICED UP for many days.

The 72 hour QPF shows all that precip running NE along the boundary. That precip falls as rain, sleet, freezing rain and snow.

It’s really Friday onwards which gets interesting across Texas and Oklahoma as once the storm system exits up into the Ohio Valley and skies clear out late weekend and early next week, we’re going to see some of the coldest nights in several years, perhaps all the way to the Gulf Coast.

By Saturday, highs are projected to stay in the 20s ALL DAY in Dallas. We could well see OKC stay in the 10s btw.

Sat night lows. (not too bad but it’s sleeting, snowing, perhaps freezing rain too)

The REALLY cold air appears to arrive early next week. OKC could easily go below 0 if it doesn’t late week into this weekend. Perhaps 2 or 3 nights below 0 with this surge in fact.

The arctic air is clearly taking direct aim at the Rockies, Plains and Midwest this week but by next week, it shifts east. Enjoy the warmer air of this week East Coast as you get hit next with a few days below freezing from DC, perhaps as far south as Richmond, VA on north.

Here’s the latest 6-10 day temps off the CPC.
