Coldest of the Season

Temperatures and wind chills are at the coldest they've been this season, thus far.

Here are some numbers to mull (and pout!) over...

Record cold...

As most of you know, it has been quite cold up here in the Northern Plains over the past month. Last week, was particularly cold with several areas over North Dakota and Minnesota reaching record lows. Wednesday morning several locations bottomed out in the -30 to -35 degree range, setting all-time record lows for the date. The Grand Forks Int'l Airport (KGFK), reached a record low of -33° F, while Hector (in Fargo) recorded it's own record of -31° F.

Here's hoping for the rebounding temperatures yesterday and today continue over the next week. It's not looking good. We'll probably drop back into the teens and 20's this week for highs, but at least the sub-zero high temperatures are gone for the time being.

A whole new definition

This certainly ranks right up there with the most counties I've ever seen included in one severe weather warning. It gives an all new definition to the term "blanket warning!" This is just crazy...

That's 25 counties whole or partially included in this warning! Granted, we're dealing with an intense squall line here. Also of particular note is the forward progression! Moving east at 80 mph!?! The line itself, isn't moving eastward quite that fast. I'm assuming the NWS caught the 80mph out of some SCIT information for an embedded cell in the echo wave pattern. Either way, seems like folks in Illinois and those back home in Indiana are dealing with some damaging winds this evening.

Soon enough, they'll find themselves at 10° or 20° F with snow falling... and winds at 30 mph! Pretty incredible system...

Colder than a Bi-otch!

That's right... Not only is it 16 below zero outside at this hour, but with the wind, it feels like -35° F. That's flipping cold, folks! Definitely reason enough to have Wind Chill Advisories in effect for a good portion of the Midwest.

But just wait... The 00z GEM this evening has temperatures across much of eastern North Dakota and Minnesota with temperatures well below -20 Sunday morning. In fact, it had -34° F at 12z on Sunday. The NAM and GFS were considerably more mild, but take that as a grain of salt. (heh, pun!) They're not much better. I mean, really... what's the difference between -15 and -34°? Let's assume no wind.

We'll see how things pan out this weekend. I'm done for the weekend, work-wise, so I'm going into hibernation mode for a couple of days. I'll check in sporadically for temperature reports and will verify what I observe.

A lot of us across the Midwestern and Eastern US are in for a crisp week and a half. So, keep warm out there, folks!

Cold-ness!

As I expected, we officially reached the first sub-zero temperatures of the season last evening.

Here are the obs from Grand Forks Int'l...

Winter Weather Advisory

While it isn't the first winter weather advisory of the season, per se, it is the most significant. A weak clipper system will progress southeast over the region this evening and overnight, bringing some accumulating snows to the area. It shouldn't be much to cause any big issues, but slick spots on the roads will still likely be found out there, I'm sure.

...WINTER WEATHER ADVISORY REMAINS IN EFFECT UNTIL MIDNIGHT CST TONIGHT...

A WINTER WEATHER ADVISORY REMAINS IN EFFECT UNTIL MIDNIGHT CST TONIGHT.

.SNOW WILL CONTINUE TO SPREAD FROM WEST TO EAST ACROSS NORTHERN PARTS OF THE REGION INTO MID EVENING WITH THE PASSAGE OF A STRONG COLD FRONT. 1 TO 2 INCHES OF SNOW ARE FORECAST TO ACCUMULATE ALONG AND NORTH OF A LINE FROM MADDOCK NORTH DAKOTA THROUGH HALSTAD MINNESOTA TO MAHNOMEN MINNESOTA.

WINDS ARE EXPECTED TO BECOME NORTH AND RAPIDLY INCREASE TO 20 TO 30 MPH WITH SOME HIGHER GUSTS INTO THE EVENING. COMBINED WITH THE NEW SNOW...VISIBILITIES WILL BE REDUCED ESPECIALLY IN OPEN COUNTRY CREATING HAZARDOUS TRAVEL.
In addition, much colder air will filter in behind the associated cold front tonight. I wouldn't be surprised to see our first sub-zero temperatures tonight. Ugh!
