No I am not trolling at all. MSP deserves a dumping. I was just pointing out that the trend in the model runs is in the wrong direction. The EURO could easily still be on board and the there have been alot of late south trender this winter.

I admit, i'm pissed at the trends so i apologize if i took some of your comments the wrong way. Models are still all over the place but it's not looking good for msp & s MN for snow.

Going to be a mess, and less snow for MSP I think, sleet at the least, more likely rani nosing in for a large portion of the event.

Yeah, mpx hinting at throwing in the towel on snow amounts for s MN cwa.

AREA FORECAST DISCUSSION

NATIONAL WEATHER SERVICE TWIN CITIES/CHANHASSEN MN

1224 PM CST MON FEB 27 2012

.UPDATE...STILL LOOKING AT THE TRENDS ON THE UPCOMING STORM. NOT A

SIGNIFICANT CHANGE IN TRACK OF THE SYSTEM BUT A CHANGE IN THE

AMOUNT AND DEPTH OF THE WARM LAYER WRAPPING INTO SOUTHERN

MINNESOTA. WILL PROBABLY MAKE A FEW CHANGES IN SNOW AMOUNTS IN

UPDATED FORECASTS THIS AFTERNOON FOR THE SOUTHERN PART OF OUR

AREA.

don't like how FSD, the National weather service out of eastern South Dakota goes and issues warnings before other regions and before they know the exact track then ends up cancelling them.

Granted it's a hard storm to predict but still the other NOAA areas didn't bother with warnings so early on. They stuck with watches until they were sure what was going on. FSD issues and ends up cancelling warnings too often. Predicting snowfall amounts in the forecasts so far ahead of time doesn't help things. It only makes it irritating when the storm inevidably does not produce what they predicted, which is almost always.

Then we'll get 4 inches when they aren't even predicting much more then an inch. That's the way of things. : )

FSD is still sticking with a dumping here as they have for the past 2 days despite other models suggesting it will be north. If we get it I'll post and applaude them.

WCCO calling for 1/4"+ of ice before the snow starts, I hope to god it stays cold enough for all snow. 1/4"+ of ice....YIKES!

I just don't see that happening, I really think the models are overestimating the warm side of this thing.

They are predicting the mix to take place overnight, for that to hold true it would have to have a pretty significant warm side to it. I really don't think the models have a good handle on this storm yet.

I am interested in your opinion, do you buy into how strong the models are portraying the warm side of this storm to be?

The warming in the models are probably legit as the system is slowing and that gives more time for the warmer air to make it north...i'm not totally sold on the L tracking north of FSD to MSP, seems kind of odd for a late feb storm but then again this is an odd winter. The system is still off the coast and maybe not totally sampled well yet, 0z runs tonight should clear alot of issues up though. IMO :)

guess no snow lovers here in southern MN likes the 18Z NAM run? damn, talk about blowtorch.

If msp is a miss with snow for the upcoming storm, MPX says you will have another shot on friday

IN THE EXTENDED SYSNOPTIC-SCALE MODEL AGREEMENT IS REASONABLY

GOOD IN THE LONG RANGE PERIOD...WITH A LARGE UPPER TROUGH ACROSS

THE ROCKIES MOVING SLOWLY EASTWARD. SOLUTION DIFFERENCES BECOME

MORE SIGNIFICANT BY DAY SATURDAY...WITH THE GFS AND THE GFS

ENSEMBLE MEAN MAINTAINING CONSIDERABLY MORE AMPLITUDE AND SPEED

CROSSING THE MISSISSIPPI RIVER. OTHER SOLUTIONS...INCLUDING THE

00Z ECMWF/UKMET/ECMWF ENSEMBLE MEAN AGREE ON MUCH SLOWER EVOLUTION

WHILE LIFTING THE TROUGH NORTHEASTWARD. OVERALL...ANOTHER SIGNIFICANT

WINTER STORM COULD AFFECT AREAS FROM ABOUT KANSAS CITY TO MINNEAPOLIS

FRIDAY AND FRIDAY NIGHT...WITH PERHAPS A FOOT OR MORE OF SNOW.

The local MN news outlets seem to think the warm air is going to play a pretty big role. I tend to think they put to much faith in the GFS.

Rule #1 of forecasting: Do not wish cast.

All of the major model guidance has trended warmer and further north with the track, not just the GFS.

Yeah you are right, and one must look into why the north track, and in this case it is legitimate and realistic given the setup and the upper level config. I can't say it enough, lack of arctic air across the cold sector will limit deepening rate...resulting in a farther N warm front and stronger height falls northward. The occlusion takes much longer to sufficiently cool the low levels.

The low has not even made landfall yet. I am simply stating that I don't really buy into how significant the models are saying the warm side of this system will be.

Completely agree here. Such a meteorological domino effect, it's crazy. 2-3 days ago, the airmass behind the Sunday system was progged much colder allowing for the stronger baroclinic zone, deeper system, quicker occlusion, further south track, more snow here.

Now it's a warmer airmass to the north of the system than progged, weaker baroclinic zone, weaker system, slower occlusion, height falls north, warmer air north, rain/sleet.

As a snow lover I hate it.

As a meteorologist, it's fascinating.
