Go West Young Man? Perhaps Not Today. 



BLIZZARD WARNINGS: Mid-Mississippi Valley to Ohio. 
WINTER STORM WARNINGS from Arkansas to Maine

8:50 AM EST 12/26/12 (Winter Stormcast Team/Forecaster Jason Warren)


Some subtle, but important changes have been made to the forecast regarding the  Midwestern major winter storm. Since Christmas Day, models continue to trend colder and southward with the storm. This means the axis of heavy snow will shift slight southward, and the threat of mixed precipitation will also shift slightly southward. 


With these changes in mind, it still looks like the heaviest snow will fall:
  • Across southern IN and far western KY, northeastward through western and northern OH. 
  • Recent models have shown snowfall totals in excess of 12 inches across portions of this area through Thursday morning. 
  • Strong winds will produce considerable blowing and drifting snow which could lead to white-out conditions at times.
There is still some uncertainty regarding the track and strength of the storm, but models are coming into much better agreement. 

This is expected to be a dangerous, high impact event with very heavy snow, blowing snow, and possibly some icing issues. Stay tuned for additional updates.

Merry Christmas from the Sticks. Nothing like snow on the ground in a "surprise" little over performer on Christmas. Roads were terrible last night as we had 3 inches of snow and almost no plows until late evening. Hopefully this weekend we can all get in on a little holiday magic. Right now I will enjoy it before the rainstorm on our doorstep washes it all away. Here is to a better winter!

Andy, any chance this one slides east out to sea a little bit and bombs out some? Looks to me to have too far a northern track for that, but wondering what your thoughts are.

We are toast for this one. After this is when the real fun starts. If you like snow get your shovel ready. The next 10 days after this flood look fantastic.

Merry Christmas, thanks for the info for a fellow Mason-Dixon liner.

A Belated Merry Christmas to my FF friends. We're experiencing some pretty heavy sleet right now in Catonsville with slightly windy conditions. How is it in other areas?

Snowing at a pretty good clip here in NE CC, Pat. Already about 1/2 an inch since it started coming down about 9 this morning.

Hoping to be able to visit folks down your all's way off of US 40 later today, looks like temps will continue to rise throughout the day...

Snow... and more than I saw last winter here in Lutherville/Timonium area..... Go figure, we are hosting the family party today!

Merry Christmas to you all... everyone be safe in your travels!

Moderate to heavy snow here. 28.4 degrees. Half inch of fresh snow on the ground. About 1/4 of the ambient snow cover melted from the 3 inches on Christmas Eve. We are completely white again here. I will take some pictures before we change over this afternoon. I think where I sit I might squeeze out 4 fresh inches before muck and mess.

R/S line creeping northward...oh, well, here's to Saturday's event, hope it pans out...

What I wouldn't give for 10 degrees colder and the L to be 300 miles east and south... :-)

Andy, Southern York County Pa said...

2 inches on the ground here and moderate snow falling.

NE CC switched over to ice pellets @1300 or so and now plain rain...

Snow measurements inaccurate due to ice/rain, but at least 1.5", maybe more...

Andy, Southern York County Pa said...

Just under 3 inches of snow today. Right now 32 and light drizzle after some moderate rain and sleet.

Two over-performers.... what is in store for Saturday?
