Mother Nature is finally relenting.. but not after giving southern Manitoba a parting shot of Arctic like weather this past week including blinding blizzard conditions Thursday, then bone-chilling frigid cold Friday with windchills of -40 to -45. The good news is that the worst of the bitter cold is over.. for at least a week anyways.. as a milder Pacific flow sets up over the Prairies this week, pushing out Arctic air that has been entrenched over southern Manitoba much of the month. Today will see temperatures near the normal high of -13C, and with sunshine and light winds, it will feel some 20 degrees warmer than Friday. Sunday is looking even better as temperatures finally climb into the minus single digits for the first time since Jan 1st. The rest of the week is looking wonderful.. dry and mild with temperatures well above normal reaching the freezing mark by mid week, then a January thaw likely by the end of the week as temperatures climb to +1 to +3C over the Red River valley. This will be welcome news for winter weary Manitobans who have had endure 2 straight weeks of cold and snow, icy roads and general cabin fever. The good news is that the warmup will not be accompanied by any major weather systems this week, so the week is not only looking mild, but precipitation free as well! The next system that poses a threat for precipitation over the RRV will be next weekend (Jan 21st-22nd) with some possible snow, rain or freezing rain moving into southern MB. Until then .. time to finally get back outside and enjoy the outdoors. Let the warmup begin!

Another storm system is getting organized in the American midwest and will be tracking into Minnesota by Tuesday bringing another round of snow to southern Manitoba to begin the new year. Snow from this system is expected to spread into southern Manitoba during Monday, and become heavier Monday night into early Tuesday before tapering off. Snowfall amounts will range from about 5-10 cm in the Winnipeg area to 20 cm over the southern RRV into SE Manitoba by Tuesday evening. This system is not expected to be as intense as the Christmas Day/Boxing day storm which brought heavy snow and blizzard conditions to much of southern Manitoba including Winnipeg. However, snow and increasing winds will make for difficult travel conditions later Monday through Monday night into Tuesday morning especially over southern RRV and SE MB. Heavier snow of 20-30 cm is possible south of the US border in northern ND and northern Minnesota as well as NW Ontario. Be prepared for poor travel conditions and possible roads closures if you plan on travelling south or east of Winnipeg Monday into Tuesday.

Tuesday evening. Heaviest amounts expected S and E of Winnipeg
This system comes on the heels of the snowiest calendar month in Winnipeg in almost 60 years. Winnipeg saw 68.8 cm of snow in December, 3 times the normal snowfall for December (23 cm) and the snowiest month in the city since Nov 1958 when 77 cm of snow fell. The snowfall has wiped out the city's snow clearing budget, which was at a surplus heading into December given last year's tame winter and this year's mild fall. The city ended up spending $39 million on street clearing operations in December, $11 million more than budgeted.

After a brutally cold weekend that saw temperatures drop to the minus 30C mark and windchills of -40 or lower, southern MB awoke to a different world this morning as temperatures soared into the minus single digits by 8 am.. a difference of +25C from 24 hours earlier. In Winnipeg, the temperature at 8 am was -4C, after being -30C at 8 am Sunday, the 18th greatest temperature rise within 24 hours in Winnipeg since 1953. Southwest winds ushered in a milder Pacific airmass over southern Manitoba overnight, flushing out the Arctic air that had been entrenched over the area since Dec 9th. And the good news is the above normal temperatures should continue the rest of the week, allowing for a pleasant lead up to the Christmas holidays. A couple of fast moving clipper systems will bring an occasional coating of snow (2-4 cm) both today and Wednesday, but overall, no major system are expected to impact southern Manitoba this week.

Potential winter storm for Christmas Day/Boxing Day?
The benign weather pattern may come to end over the Christmas holiday weekend as long range models are indicating the potential for a strong winter storm to move across the northern Plain states and/or northern Minnesota by Christmas Day or Boxing Day. It's much too early to say if this storm will impact southern Manitoba and how badly, but there's growing consensus that a major storm system will be tracking across the northern Plains sometime over the Christmas/Boxing Day period. At this point, all we can say is to keep an eye on this potential winter storm that could be impacting holiday travel in southern MB (especially RRV and SE MB) depending on how it tracks. Realize however that models will be jumping around on the possible solutions on this storm system over the next few days until they get a clearer picture of where this storm will track. Stay tuned..

Residents of Winnipeg and southern Manitoba are digging out after a major winter storm brought heavy snow, high winds and blizzard conditions to much of the Red River valley Tuesday into Wednesday. In Winnipeg, the storm dumped 25-35 cm of snow over the 2 days, with strong winds gusting to 70 km/h producing significant blowing and drifting snow. It was the city's worst winter storm in several years.. perhaps one of the worst since the blizzard of April 1997. The storm was even worse outside the city as powerful winds of 70 to 80 km/h produced blizzard conditions over the western and southern RRV, leading to the closure of many highways including the TransCanada from Headingly to the SK border, Hwy 75 from Winnipeg to Emerson, as well as highways 2 and 3 southwest of the city.
But now that the storm is ended, there's a new winter hazard to prepare for.. bitter cold. A massive Arctic airmass has settled in over western Canada, and this colder airmass will be be spreading into southern Manitoba over the next couple of days. By Friday, daytime highs are only expected to around -17C with lows in the minus 20s. This will be the first time in 7 weeks that temperatures will be below normal in southern Manitoba. In Winnipeg for example, the average daily temperature has been above normal since Oct 21st, a streak of 48 straight days as of Dec 7th. This streak will come to an end Thursday as a new streak of below normal temperatures begins. Temperatures will remain well below normal through the weekend into next week, with even colder air moving in for mid week next week. Temperatures may dip to -30C or lower by Dec 14th, mid winter cold we haven't experienced since last winter. So break out the parkas and get those block heaters ready.. much colder weather is on the way!

strong winter storm affecting RRV/SE Manitoba
The first major winter storm of the season is on its way into southern Manitoba as a low pressure system over eastern North Dakota slowly tracks towards the Canadian border. Heavy snow from this system is already affecting northeast North Dakota this evening, and will continue to spread north into southern Manitoba through tonight. Snow is expected to reach the Winnipeg area by 3-4 am overnight and become heavy by the Tuesday morning rush hour. In addition winds will be increasing from the north gusting to 60-70 km/h which will produce poor visibilities in blowing and drifting snow. Give yourself plenty of time to get to school or work tomorrow as road and traffic conditions will be poor.
Snow will continue through Tuesday into Tuesday night, moderate to heavy times, with 15-20 cm possible by Tuesday evening. The evening commute will be slow and treacherous with double to triple commuting times. Winds will continue strong out of the north with gusts to 60 km/h in Winnipeg, with even higher gusts of 70-80 km/h possible over the western and southern Red River valley. These areas will be most susceptible to blizzard conditions given the strong winds and wide open terrain. Don't be surprised to see road closures on Highway 75 south of Winnipeg, Highway 1 west of Winnipeg, and highways 2 and 3 southwest of the city. Snow is expected to continue Tuesday night with another 5 cm possible before the storm starts winding down on Wednesday, although blowing and drifting snow may continue to be a problem. All in all, a significant winter storm to usher in much colder weather for the end of the week. After being AWOL in November, winter is making a forceful return in December! Get ready!
