Jim Marusak Posted February 20, 2012 Share Posted February 20, 2012 sorry for chiming in late here. but looking at what the temp/dewpoint spreads are here in the twin cities attm as well as RST and DLH, could make for an interesting start to the storm. 5/-6 in MSP, 4/-5 in RST, and 3/-7 in DLH. i would guess all snow in DLH, but RST/MSP, going to be awfully close, depending on the intensity, probably won't stay rain more than an hour if it starts that way. and the model soundings could go either way. clouds outside, CU2 AS6 CC2 .

Huge flakes with the heavier bands, awesome. Link to comment Share on other sites More sharing options...

Jim Marusak Posted February 21, 2012 Share Posted February 21, 2012 well, the p-type question is answered. starting as snow right now. rather small, moist flakes. but snow, not a snow/rain mix. Link to comment Share on other sites More sharing options...
prinsburg_wx Posted February 21, 2012 Share Posted February 21, 2012 I have just over 2" on the ground, probably would have been 3" or so but the 1st hour or so melted on contact. Roads are in terrible shape with heavy slush.... Good job by MPX on the event. Link to comment Share on other sites More sharing options...

Roads are in terrible shape with heavy slush.... Good job by MPX on the event. Better than me lol. I gave it a quick look, but I thought the SE flow and warm BL would stay mostly rain with a mix at best. Rates here certainly helped. Link to comment Share on other sites More sharing options...

Rates here certainly helped. No doubt it was the rates that helped change it over, your call was good hard to predict rates. The heaviest is over here as i see montevideo/granite falls has gone back to lgt rain. Link to comment Share on other sites More sharing options...

Chinook Posted February 21, 2012 Share Posted February 21, 2012 I-70 is now closed from Goodland westward. I-70 was closed?? How long were the conditions bad from Goodland to Limon? We had 40mph wind gusts here. It's more than I expected. Link to comment Share on other sites More sharing options...

#NoPoles Posted February 21, 2012 Share Posted February 21, 2012 Prinsburg, thanks for posting that Boulder had put up a Blizzard Watch...hadn't really been paying too much attention to the weather, and I would have driven right through that area...instead I took I-25 N to 76 to 80...no problems at all...a tad windy, but no biggy...

StormJr Posted February 21, 2012 Share Posted February 21, 2012 Color me impressed. Started as a rain/snow mix in the west Metro here in MSP, but quickly (30 minutes) went to all snow. Been snowing moderate to heavy ever since. I just went and measured snow depth (which of course doesn't take into account settling/melting at the onset) and it was between 2-3" with more to come over the next 2 hours. Here are some pics I took with my phone a few minutes ago: Link to comment Share on other sites More sharing options...

ksstormhunter Posted February 21, 2012 Share Posted February 21, 2012 Just updated SmartCast at 03Z. Showing the Minneapolis and Rochester with an additional 2" of snow through the next 12 hours, with the heaviest snowfall between 06-08Z, with rates up to .5" per hour across this region.

cmichweather Posted February 21, 2012 Share Posted February 21, 2012 I think I busted a bit low on predictions i'd imagine official measurements tomorrow will be around 4-4.5", nice snowfall and extremely moist I wouldn't be suprised to see the LWE around .6-.7 ish.

StormJr Posted February 21, 2012 Share Posted February 21, 2012 Just went out and measured 3.5"-4" in the parking lot (Yes, I know, not the best place to measure...) From watching radar, it does look like the heaviest dbz's stayed over the west metro for almost the entire event, so I would expect similar amounts to be reported in the area including Chanhassen.
