Firstly, the cold! Noticed it’s cold out? Certainly if you live basically anywhere from Denver to Atlantic City, your running comfortably or uncomfortably below normal and tonight will be a heck of a cold night, especially from North Dakota to North Georgia. It hit 18 below zero this morning up in Rudby, ND, that’s pretty chilly for late March that’s for sure.

Here’s the thicknesses off the GFS for 0z Thursday.

 

Here’s the 850s for the same period!

GFS 2 metre temps!

2-metre temps for Thurs morning!

 

So while temperatures have dipped into the mid single digits across Minneapolis over the past few mornings, it may finally make it to zero tonight there with near zero even stretching down into northern Iowa while Chicago edges towards the 10-degree mark. Teens across much of Indiana, Ohio with perhaps low teens, upper single digits across parts and western and central Pennsylvania. 20s should reach Atlanta tonight too, so certainly cold for late March.

The cold sticks around and it wouldn’t surprise me to see another couple of mornings like that with the type of pattern we have going here and the longer this JANUARY-LIKE cold hangs around, the more impressive it becomes, afterall, many of the Upper Midwest locales which was stuck in the low to mid teens mid afternoon, should be in the upper 30s to low 40s by now.

As for the big mess that’s sliding out of the Rockies late week in through this weekend looks to bring a significant snow to Denver, possibly upwards of a foot though I am cautious with that because there have been a few occations were it looked good and actually was somewhat of a bust.

Here’s the GFS surface out at 30 hrs, surface low to the south, swinging quite a lot of moisture up against the Front Range!

 

I guess i’ll go for 4-8 inches for Metro Denver with over a foot to the west of town.

The system continues to worry me with regards to the warm, moist air which gets lifted into the South from east Texas to Georgia as the low swings into Texas. We’re going to see a major snowstorm across Kansas, Missouri up into southern Iowa from this with a 6-12 inch swath, local amounts perhaps 14-18 over the upslopes of the Ozarks.

Even by 60 hrs the GFS still piles moisture up against the Front Range while the low remains to the south but the concern is, moisture breaks out early from E TX to Carolinas with focus over MS, AL up into TN.

Here’s by 84 hrs (Sunday), bet your bottom dollar that’s a wild afternoon with severe severe and flooding rains across the Southeast with a ton of moisture while a blizzard rages on the cold sector.

 

Here’s the snow chart out at 90 hrs. Note the model has backed off on the 2ft snows across Iowa but has a nice swath extending from Denver across Kansas with a bullseye over Missouri.
