Arctic Cold and Snow for Much of The Rockies/Central US

[CaptinCrunch]

A large part of the nation will be subjected to a harsh attack from Old Man Winter next week. It will all get started this weekend as very cold air makes a move out of northwestern Canada. The cold will reach the Northwest and northern Plains first then spread south and east from there. The advancing front edge of the bitter blast is likely to trigger a major snow event from Montana, across the Great Plains to the Upper Midwest. Southern Canada will also be hit pretty hard with snow and blowing and drifting snow. So, how cold is cold? The minus 25 up in Northwestern Canada is in degrees Celsius, which converts to 13 below zero in Fahrenheit. If the entire core of the arctic air mass comes down during the middle of next week the temperature may never get above zero degrees Fahrenheit through all of south central Canada.

It's about time.

Excellent and a warm up for Florida after a november snow! Ice Fisherman are cheering amonst others..

I was looking some models this morning that seems to show a big winter storm ramping up for next week for the NW, tracking SE across Utah, Colorado, then east. Could we see another blizzard in Colorado? Stay tuned.

[NEWeatherguy]

I have feeling this could be a multi-faced system. The northwest sector (Dakotas, Western Nebraska, Wyoming and Colorado) may deal with a blizzard. Some mixed precipitation may develop in a 100-mile-wide area east of there. Finally, rain and even a chance of severe thunderstorms may occur for parts of eastern Nebraska, Iowa, Kansas and Missouri and points eastward.

There's been hype of a significant snowstorm here in Utah for Monday, too.

[CaptinCrunch]

Temps in the teens will move south over the next couple up days and make it as far south as southern Kansas. NTX will see highs in the upper 30's to lower 40's for Thursday and lower to mid 40's on Friday. There is also a chance of wintery precip for NTX in that time frame as well.

Somewhere across the Southern Plains there will be a significant ice and/or snow event this week. Wednesday night into Friday will be very interesting from Dallas and Texarkana northward into Oklahoma, Arkansas, Kansas, Missouri, and Illinois.

Here are the GFSx and the precipitation forecast chart for next week (7 days out). If this was to verfy a Monday Night/Tuesday snow/ice event would be instore for much of NCTX and OK.

With just 4 days left in November the Avg. Monthly temp is 57.5 degrees, which is 1.7 degrees above normal, but with the arctic front due in here around late afternoon Wednesday and Thursday not expected to get out of the 30's it should cap the month off right about normal.

Now for the good stuff, over the weekend a couple of our local Met's (channel 8's Troy Duncan and Pete Delkus) have stated that December is expected to be from below to much below normal for temps and above normal for precip for much of NCTX.

I saw a news release this afternoon which had alot lower values than that when you factor in the windchill. -45 C in Fort St John. BC ( that equates it -49 F ) thats mighty cold, even for us up here!

time to break out the hot chocolate and make a snow angel! long time in coming haha! cheers

[bob rulz]

We're supposed to see highs around 25 degrees with lows near 10 on Wednesday and Thursday after getting significant snow (up to 6 inches just through tonight, with more Tuesday through Wednesday morning). This is truly some cold weather!

WEST AND SOUTHERN PLAINS...

AN ARCTIC HIGH WILL BE SLOWLY GAINING TERRITORY THROUGH THE
PERIOD....WITH THE WEST AND THE SOUTHERN PLAINS REMAINING UNDER
THE GRIP OF THIS AIRMASS FOR MUCH OF THE PERIOD. THE POSITIVE
ANOMALY IN WESTERN CANADA WILL KEEP PACIFIC SYSTEMS AT BAY...WELL
OFFSHORE THE WEST COAST... THROUGHOUT THE PERIOD.

EAST...

THE MEDIUM RANGE FCST OVER THE ERN HALF OF THE COUNTRY REMAINS
CHALLENGING DURING DAYS 3-5/THU-SAT. AS LUCK WOULD HAVE IT...THIS
SYSTEM POSES A SIGNIFICANT THREAT OF BOTH LIQUID AND WINTRY
PRECIPITATION BEFORE IT MOVES OUT INTO ATLANTIC CANADA AND THE
WESTERN ATLANTIC. THERE IS A DECENT CONSENSUS UPON DEVELOPMENT OF
A SIGNIFICANT WAVE IN ASSOC WITH MID LVL TROF EJECTING FROM THE SW
CONUS/PLAINS... BUT NO AGREEMENT UPON TRACK/STRENGTH/TIMING. THE
26/12Z ECMWF ENSMEMBERS SUPPORTED THE 00Z ECMWF...HOWEVER THE
LATEST 00Z ECMWF ENSMEMBERS APPEAR TO BE TRENDING TOWARDS A MORE
PROGRESSIVE SOLN. MEANWHILE...THE 06Z NCEP ENSMEMBERS HAVE SLOWED
DOWN FROM WHAT THEIR 00Z COUNTERPARTS WERE
ADVERTISING...REINFORCING THE IDEA OF COMPROMISE. AN INTERMEDIATE
SOLN SIMILAR TO THE 06Z GFS APPEARS BEST AT THIS TIME. THE 12Z GFS
AGREES ON TIMING OF THE FRONTAL BOUNDARY...BUT NOT IN RESPECT TO
THE SURFACE LOW POSITION LATE THIS WEEK/THIS WEEKEND. SINCE NO
ADDITIONAL VALUE WAS ADDED BY THE VARIOUS 12Z MODELS CURRENTLY
AVAILABLE...NO CHANGES WERE MADE TO CONTINUITY.

If you get snowcover in NW UT then when that High builds in you are going to fog in big time.

Looks like below zero temps are forecasted:

We've had a very warm November so far with little snow.

[wx247]

Winter Storm Watches have now been posted for much of Eastern Kansas and Western/Southern Missouri. Our local NWS is calling for approximately .25" of ice followed by 5-7" of snow!

[wx247]

Winter Storm Warnings now in effect for western Missouri, eastern Kansas, and much of Northeast Oklahoma. Ice Storm Warnings are in effect for the Kansas City area and Winter Storm Watches continue from Southwest Missouri northeast toward St. Louis and into Central Illinois.

Yeah, we would, but it doesn't look like that's going to happen. We're going to get brushed by a cold front Friday, which won't allow the high pressure to build in. Maybe next week, though.

The initial wave of this storm was essentially a bust; barely 2 inches. However, the lake-effect kicked in last night, and now there's 6 inches on the ground here. The airport got 7.9 inches, however, so we would have sufficient snow cover for a powerful inversion to build in if a high pressure ever decides to come in and stick around.

EDIT: 8.1 inches, not 7.9 inches.

Ice storms.

Grrrr.....

Don't remind me of KC in January 2002.

Still remember spending 45 minutes getting to work with what was normally a 10 minute drive because every route but one didn't have a power line or tree in the way.
