Here's a nice graphic from NWS Grand Forks showing snowfall amounts across eastern ND and northwest Minnesota from yesterday's blizzard. A good swath of 20-30 cm from Fargo into northern MN. Over southern MB, snowfall amounts look like 2-4 cm across far southern Red River valley and southeast MB, with 5-10 cm in the Sprague area.

Snowfall from Tuesday's storm

It looks like SPRING will finally be arriving in the next few days and sticking around for quite some time!
ReplyDeleteThe models are indicating a warm push of air next week with Southern Manitoba being on the northern edge of that warm bubble of air!
bring it on!
Numerous records again fell in Alberta and Saskatchewan last nite. Arctic high is progged to sit around the twin cities by dawn tomorrow. With fresh /deep snow cover over SE Manitoba N Dakota and NW Minnesota expect more records to tumble. -35 to -37 C certainly possible in the hilly terrain from Sprague thru Waskish and Fosston in NW Minnesota. -30 to -35 C up and down the RRV with the colder values possible in the south.
ReplyDeleteWave over Montana generating lift and clouds that are trying to advect eastwards. Its likely they will dissipate or pass to the south. Flow turns west over YWG overnite. Doubtful how much warming/ mixing will be realized at the surface. YWG will still be under influence of arctic inversion despite warm advection aloft.
I sincerely hope this is the last time we will be talking about extreme cold.
Yes.. hopefully this is our last real cold spell of the winter. Last year, we had a -30C on March 7th, then that was it for the real cold stuff.
ReplyDeleteAnd notice that the UV index is back in the forecast.. although one questions the necessity of a UV index when it's -20C!
You know Spring is coming, when the high is -20C and the UV Index is 3 or moderate!
ReplyDeleteI am liking what the models are showing next week. Dry conditions and above-zero temperatures. I suspect a good portion of the snowpack will be gone here by the end of next week. Since we only have about 20cm on the ground, there isn't too much to melt.
It always amazes me how quick the snowpack can go here in southern MB by late March given mild enough temperatures and sunshine. I've seen a 30 cm snowpack disappear in a less than a week with highs in the +5-10C range.
ReplyDeleteA pleasant surprise.. temperatures are simply not spiking down tonite. Rob's site has barely dropped 1 degree the past two hours even with a rural drainage wind.
ReplyDeleteThe widespread SW flow across the eastern prairies/ upper midwest is yielding efficient mixing. The decoupling of surface winds is apparently being inhibited. NWS Grand Forks also has dropped mention of record overnite lows.
Doubt it will even get below -25 C at YWG with some localized areas further east maybe seeing -32 C at the lowest. Bodes well for our warm up.. yay!
One last observation worth mentioning... as the high dropped south today the return flow was able to tap a long fetch off snow free surfaces (down thru Iowa, Missouri and back up thru western Nebraska, S Dakota into). Significant modification likely occurred. Seems like a simpler explanation anyways lol. Forecasting is always a learning experience I guess.
ReplyDeleteLooks like EC is starting to back way off a "spring warmup" for next week. Forecasting below normal daily highs now. Oh well, maybe one day....
ReplyDeleteI'm not sure how accurate accuweather is, but they are calling for colder than normal until at least the 1st week of April. I hope they are wrong.
ReplyDeleteThe new Day 6-7 forecasts seem to have a bit of a cold bias.. I wouldn't be surprised to see us closer to the freezing mark next week through Wednesday before a bit of a cooldown. Note that GFK is forecasting highs near +5c through Wednesday, although the American models are showing a slightly warmer solution than the Canadian GLB.
ReplyDeleteBy the way, some may be wondering why a windchill of -27 is forecast for tomorrow given a high of -4C. That windchill is referring to an early morning value when the temperature is -18C and there's a wind of 15 km/h. Unfortunately, the forecast does not specify that this windchill is only occurring first thing in the morning, and gives the misleading impression that a windchill of -27 will be occurring all day. It won't be.
I've added 3 new webcam images from the Winnipeg area on my webcam page, plus a link to the streaming Steinbach webcam that Scott gave. These will come in handy when we see those hit and miss convective cells start popping up in a couple months (yes, they will come eventually!)
ReplyDeleteThe day turned out much better than expected. I was expecting Winnipeg to be in the -12 to -14 range today, but it got all the way up to -9! That makes me think that tomorrow will probably be about 0 or +1 in Steinbach and -1 or 0 in Winnipeg.
