prinsburg_wx Posted February 10, 2013 Author Share Posted February 10, 2013 NIce!How much out there? I'm guessing 5"...hard to measure right now. The dreaded dry slot approching from the south though. Link to comment Share on other sites More sharing options...
ZackH Posted February 10, 2013 Share Posted February 10, 2013 Looks to me like the storm shifted north ever so slightly... depending where some of the fringe bands set up, it could be the difference between 1-2 inches and 3-4+ inches here in Grand Forks.

ZackH Posted February 10, 2013 Share Posted February 10, 2013 How much do you estimate has fallen in GFK? Its so tough to say with the blowing snow factor... We had a nice little band come through the area but it was quick... I wouldn't say more than 1.5/2 inches though. This little shield up here looks to be drying up compared to earlier. There's enough powder to make travel hectic later though when the wind really kicks in. Link to comment Share on other sites More sharing options...

Few places in this country can combine the very dry powder, cold air advection patterns, and the flat expanses to develop such blizzards. Link to comment Share on other sites More sharing options...

I was out of town for the one really nice one we had. Hoping the winds really crank later. Link to comment Share on other sites More sharing options...

All weather fanatics should try to experience the classic Red River Valley ground blizzard at some point in his/her life. It's something so difficult to replicate anywhere else in the country.

ZackH Posted February 10, 2013 Share Posted February 10, 2013 Interesting radar feature over west of Cooperstown, ND... its been consistent and growing for a few scans now. Looks like some pretty heavy snow. Could this be the start of a new deformation band trying to form? It appears that there is a little bit of filling in as far east as here in GFK. We could be in a decent spot for the pivot if this is a new band forming. Obviously nothing like the south, but I was giving up hope for more than 2 inches but maybe we could squeeze another couple out if this trend keeps going.

blizznd Posted February 11, 2013 Share Posted February 11, 2013 I live in east grand forks MN and blowing and snowing hard here since about 530 or so.... nothing horrible vsby wise but bad enough. Hard to estimate but would guess 4-5 new snow.... quite the gradient still from even EGF to the airport I imagine.... I seen on media FB pages up to 24 inches in SE Richland county ND Fairmount. UND hockey team is stranded overnight staying at the Summit SD community center as I-29 closed. Link to comment Share on other sites More sharing options...
ZackH Posted February 11, 2013 Share Posted February 11, 2013 Yup, this storm majorly outperformed my expectations. I do believe the storm tracked ever so slightly more northwest, causing us to get 4-6 inches here in the south park of Grand Forks. Of course its tough to tell because of all the drifts... but there is easily consistent 4-5 inches here at our place. We went to a party tonight when the new deformation band formed and got stuck twice on the way home. But we got the car back in the garage and everything's okay.

blizznd Posted February 11, 2013 Share Posted February 11, 2013 I finished up a set of mids....and spent many a days agonizing over this storm. Glad it worked out as expected.....Highest I saw on VNL facebook page was 24 inches near Fairmont ND....with many reports of 16-22 Wahpeton to Detroit Lakes to Bemidji. Models all along pegged this region for the hardest..... Euro overall was very very stable run to run....GFS not too bad....now its time for the winds to take care of the rest of the snow....

blizznd Posted February 11, 2013 Share Posted February 11, 2013 Zack...I did see this eve via the web the sfc low looked to go near Red Wing MN at mid evening....and this was indeed just a tad northwest than models had..... good news for us. Was getting tired of all the black snirt. Link to comment Share on other sites More sharing options...
ZackH Posted February 11, 2013 Share Posted February 11, 2013 Amen! I just went out and took a ton of separate measurements around my building avoiding obvious drifts. General numbers run anywhere from 4 to 6.5 inches. Link to comment Share on other sites More sharing options...

Siberian Express Posted February 11, 2013 Share Posted February 11, 2013 Zack...I did see this eve via the web the sfc low looked to go near Red Wing MN at mid evening....and this was indeed just a tad northwest than models had..... good news for us. Was getting tired of all the black snirt. I'm just outside of Red Wing. Had the lowest pressure reading of 29.17 (987.8) about 10:00pm. Pretty sure it's the lowest reading for the winter season too. I ended up with .47 rain/zr and about 1.5 of sleet/snow. Just to my W/NW (10 miles) there was a few more inches of snow, I was driving in a snow burst a bit past noon and it was really intense with visibility down to 1/8 or less.
