Arctic chill easing.. moderating temps on the way
After several days of Arctic cold, temperatures will finally be moderating over southern MB over the next few days. A warm front will be pushing across southern MB tonight bringing clouds and a possibility of some snow (dusting to 2 cm) . This front will keep temperatures from dropping tonight, and will usher in temperatures in the minus single digits Thursday for the first time since December 6th. Slightly colder weather is forecast for Friday into the weekend although temperatures should be close to normal for this time of year (normal highs minus 11, normal lows minus 20)

Looks like some snow has broken out in Western Manitoba!
ReplyDeleteHere's are chance to finally get some fresh snow!!!
Looks like we will have to watch out for freezing rain overnight tonight. 850mb temps are forecast to go above zero right around the time that the impulse will move through. Not expecting much in the way of accumulation, but some spots might get slippery.
ReplyDeleteInteresting!
ReplyDeleteLooks like we miss the snow again with it to the north and south of Winnipeg!!!!
working tonight real busy with pcpn expanding and freezing rain and sleet occurring northern North Dakota. so far sleet here at NWS Grand Forks.
ReplyDeleteAnyone see the potential for a good snowfall just before christmas, or will it just miss us again? TWN says 10-15 cm. Would not be good for people travelling for the holidays.
ReplyDeleteBetter enjoy this "heat wave" while it lasts cause looks like another cold blast next week!!!
ReplyDeleteWhat is with the Weather and those traditional travel holidays. Thanksgiving blowing snow and now Christmas threatens treacherous travel.
ReplyDeleteA beautiful white christmas,.. not for those who have to drive.
Please keep us posted.
Latest 12Z GFS model run has little to no precip for the next 10 days for Winnipeg. A dusting to 2 cm late Saturday night into Sunday with best chance over western half of Manitoba. The next system has now trended further south so the inverted trough that was suppose to affect southern Manitoba is weaker, less defined and further south. So southern Mnaitoba looks to be on the northern fringes of any snow late Tuesday and Wednesday and then maybe some flurries Christmas morning. So once again TWN is out to lunch with its typical doom and gloom forecast.
ReplyDeleteMixing down of warmer air aloft happening here and there where winds are stronger and there is favorable terrain. The generally lite winds are causing wide variation in temperatures making the boundary between pacific and modified arctic air hard to pick out.
ReplyDeleteDoes not look good for any good warming/mixing locally... stronger westerly flow will stay off to the higher terrain SW of here. Our flow will remain lite and variable until northerly flow takes over and colder values begin oozing south again. Another push of pacific air to come over the weekend associated with the next system, however that warm sector looks to collapse south of the border.. sigh
As anonymous mentioned, GFS was showing potential for some accumlating snow next week with an inverted trof.. but main energy seems to be well south of our region.. so chances for some significant snowfall in Winnipeg/RRV remain low for the foreseeable future.
ReplyDeleteBoy, what a snow drought we're having.. After that 10 cm dump in early October, I've had 2 cm in November and now 2 cm as of mid December. As nice as it is not dealing with snow, I must admit I wouldn't mind a nice 20-30 cm snowstorm one of these days.

ReplyDeleteLets make it five 5-6cm snow falls instead.
Thanks for answer rob. Maybe travelling won't be so bad then next week.
ReplyDeleteBut ya, I agree, I'm starving for a big 20-30 cm snowfall as well, just after the holidays please =D.
20 -30cm might just be enough to fill those Red River Gumbo crevasses appearing this week. . Those cracks are wide and deep and only a few feet apart. 6 weeks ago everything was soaked and running
ReplyDeleteTired of our cold weather? If you are planning a holiday, why not try Iqaluit...+2C today! Looks like Iqaluit should stay above freezing through the weekend.
ReplyDeleteRob!
ReplyDeleteHow much snow do you think could fall on Sunday???
Clipper moving through might give us 2-3 cm Saturday nihgt into early Sunday. NAM gives Winnipeg up to 5 cm with a stronger upper trof, while GEM shows about 2 cm with better upper support north of us through the Interlake. Either way, it's not looking like much.. although even 2 cm would be our biggest snowfall in 8 weeks!
ReplyDeleteI'm a little surprised by the forecast for Saturday night for Winnipeg.. no mention of snow. Most models would support carrying at least a chance of snow some snow for Saturday night into early Sunday. Mind you, the way this winter's going..
ReplyDeleteWell as of 8:44pm EC is calling for snow tonight starting around midnight and ending before morning. I can see a small system comming out of the north so I guess we'll have to see.
ReplyDeleteI think tonite's overnite low forecast is strange aswell.. given neutral temperature advection and that most models hint at some low level cloud lingering until around 7 am. Seems like GEM is too aggressive with that arctic high building south... and SCRIBE may be struggling again with limited snowcover. We'll see what happens...
