sounds like a plan. Strange the way the Euro is acting 

'Rex Block'.....from the MSP morning AFD. 

 

THE END PORTION OF THE FORECAST (THURSDAY/FRIDAY) HAS CERTAINLYBECOME MORE INTERESTING IN THE PAST 24 HOURS. THE GFS AND ECWMFCONTINUE TO SHOW AN OMEGA BLOCK DEVELOPING OVER THE NORWEGIAN SEAAROUND MID WEEK. HOWEVER...THE 16.00Z ECMWF TAKES IT ONE ONE STEPFURTHER AND DEVELOPS THIS INTO A REX BLOCK FROM THE NORWEGIAN SEAINTO EUROPE. THE ECMWF ALSO DEVELOPS A REX BLOCK FROM CENTRALCANADA INTO THE NORTHERN PLAINS. WHAT CONTINUITY WE HAD ON THEUPPER LEVEL LOW PASSING JUST SOUTH OF US FROM THURSDAY INTO FRIDAY ISGONE. IN FACT... THE UPPER LOW HAS SHIFTED FROM EASTERN IA ON THE15.00Z RUN TO CENTRAL SD ON THE 16.00Z RUN DO TO THE AFOREMENTIONEDBLOCKING. THE GFS BASICALLY SHEARS THE UPPER LOW EAST TO WESTACROSS THE UPPER MISSISSIPPI VALLEY AND NORTHERN PLAINS DURINGTHIS TIME PERIOD.

0z euro weaker but takes the L thru msp...lower on qpf but still 0.50-0.75 for s half of MN.

I am thinking this is going to be more of a central plains event. Even if this does go N, moisture will be limited due to both substantial DMC farther S and the very stout 1035+ high anchored over the N Plains. Right now it looks like an LBF - OMA - DSM event with much lighter amounts N. I still think you will see some snow in S MN though.

I think so too...i think MPX was jumping the gun a little or riding the euro by throwing out 80% pops into the forecast 5 days out.

Well the high pops may still verify, but the storm will have dropped most of its load by then. I actually think the end result for MN will be something in between the EC/GFS and the CMC.

LBF did the right thing and put out an SPS. A little surprised the other NE offices have nothing out yet.

You know what I was thinking? We gotta find a way to get some snow in the Front Range corridor with this storm. The upper low is right. The surface low is right. It doesn't stall here.  Here's a precip image from the 00z ECMWF showing some heavy snow near Denver. I suppose it remains to be seen if this will have a longer-duration upslope snow, or maybe just 2-4" for us. The GFS right now does not show much.

At best it would be a quick hitter. Models continue to prog a very rapid ejection...obviously you guys like those nice 4 corners cutoffs.

People overreact thinking they'll be stuck home for days is my guess.

 

Yep, good luck btw to those on this board who will be impacted by the glut of this storm.  Looks like Nebraska, Kansas, and Iowa will be the primary beneficiaries of the heavy snow and wind.  Thinking a general 8-16" in much of those states, with the higher totals really tapering east of Des Moines or so.

Kinda surprised to see this thread go quiet. The models (with exception of the Canadian) have trended colder with the system and shifted the track of the low to the south somewhat. The 12z/18 Euro joined the NAM and GFS on a colder trend. I am beginning to think that an ice storm scenario is becoming plausible across parts of southwest into south-central Kansas into western Missouri. Heavy snow accumulations of 8-14" are likely along I-70 into southern Nebraska. 

 

What do you guys think?

I agree, it is unfortunate much of this storm will be hitting locations where we have 0 members. This is a pretty big deal though, and if the GFS verifies, portions of N Kansas will be seeing some incredible snow totals.
