Deep Freeze Returns

After a short break from the cold as milder pacific air spilled across the prairies, we now will be tossed back into the deep freeze as another ridge of arctic high pressure spills into the region. 

New Map made by me from the new software called Skitch (The deep freeze arrives as an Arctic Ridge Builds in)

Temperatures will begin to nose dive into the cold range as we head into the weekend with high's stuck in the minus 20's to minus 30's, all thank's to our wonderful friend we call arctic high pressure!
 

Tonight will be a fairly nice one compared to our cold en-devour ahead, light snow and local blowing snow taking place with temperatures approaching the -25C mark as high pressure nears the region, though quite cold out in Southwest Manitoba with temperatures near -35C overnight. Things will warm up for the day Thursday with temperatures into the low minus 20's with windchill values in places approaching the -40's. Sunshine will be the main event. 

 The real chill will arrive on Thursday Night as temperatures hit rock bottom and approach the -36C mark in the West and -33C in the East. Factor that in with windchill's the air will feel closer to -42C to -46C in the West and -41C to -44C in the East, that will be likely if the wind speeds surpass 15 to 20 km/h in most places. Add all of that up more Windchill Warnings will likely be issued in the next few days. Environment Canada has already in fact issued a few earlier today for Western Manitoba .See Picture on the left and click on this text.

 Friday will be a recovery day as temperatures rebound closer to -20C instead of it being in the minus 30's with sunny skies again, an alberta clipper will arrive into the area of Southwest Manitoba overnight into Saturday pushing some cloudcover into the region. That will help our temperatures stay away from the -35C mark and away from the -45C windchill's. The cold weather will be short lived as we see warmer temperatures push eastwards for the day Saturday and Sunday, woo hooo!

Warmup on The Way For The Weekend, Though It Won't Stay Long!

After a cold week we will be given a chance to warmup and get a break from the deepfreeze in southern Manitoba.  


Temperatures forecast for Sunday January 27th, 2013 at 5am, much warmer throughout the day with temperatures reaching the -5C mark or cooler.

The warmer temperatures are heralded by the alberta clipper that passed by our region yesterday, chopping up the Northwest flow and created a zonal (west to east flow) which will enter the region the day on sunday. The warm pacific air will be moving across Alberta and Sakatchewan today entering into Manitoba on Sunday, giving a chance for our temperatures to rise into the high minus teens to low single digits (-17 to -6C), compared to the -30C and cooler overnight lows with the windchills colder than -40C during this past week, including the biting cold daytime highs.

Friday will feature biting cold temperatures still as we remain in an arctic airmass with daytime highs in the low minus teens to high minus teens, and mainly clear skies throughout the night and day.

Saturday things will gradually warmup as we get into the pacific airmass with daytime high temperatures approaching the very high minus teens mark (-13C in the East to -8C in the West).
Sunday will be even warmer as we get into the mild pacific airmass with daytime highs in the low minus single digits (-8C in the East to -4C in the West). There also will be a fairly high chance for snow flurries overnight as another shortwave approaches from the West, cloudcover will also be in place if there are no flurries around as a moist mild pacific airmass is in place ahead of the system.

Outlook For Next Week

The (Coldest day) Friday.

I hate to say it folk's colder weather and likely for the last time will return next week as arctic air drives south again. Starting off on Monday an area of low pressure will be trekking across the region bringing a possible 5 to 10cm of snow during the morning in the Western Half of Manitoba to Late Afternoon in the Western Red River Valley, and Red River Valley by early evening. It will eventually drift into Eastman by the late evening hours. Cloudcover will remain during the night behind the system as residual moisture. The system will also bump our temperatures up to near -4C in the West and -2C in the East during the day before the snow arrives (warmest day of our warm spell overall by the looks of it). Things will get much colder next week as an arctic airmass dives south again, thank's to the cold air return from the NW by the low pressure system on the day Tuesday. The main coldsnap could arrive on Friday where daytime highs will be in the -25C to -30C range and maybe windchills near -40C on Friday & on the weekend.

In the long long range the Good thing about this expected coldspell is that it won't last long in terms of days.... by the 11th of February things will get much warmer and will be dealing with less snowfall. The cold arctic air will likely be unable to reach further South as the doors close to the arctic air, by the second week of February. Head over to Another Eastern Cold Shot For February by Brett Anderson Accuweather for more indepth ideas.

Another post will be on the way Monday detailing our snowfall forecast, until then enjoy your weekend folk's and when you have a chance enjoy the warm weather, cheers!

A little snow and then a blast of cold arctic air for the weekend and next week!

I'm back in business folks! A good look at our weather is in the schedule for tonight so let's begin....

A lot has happened in our weather over the past 2 weeks including a few good blizzards, and crazy temperature swings. However we will mainly just have a look at what's on the horizon in terms of conditions for South Manitoba, for the next week or so. Guess what? I have some news to bring to you all "cold weather is on the approach, and not in a good way".That is winter I guess, and I don't like being the bear of bad news....

A clipper system will be moving across Southern Manitoba for the night ahead bringing scattered areas of snow into the Red River Valley and most of the province. Snowfall accumulations of 7cm can be expected in most spots by tomorrow morning, as the clipper system moves off into NW Minnesota. Areas of blowing snow will be very likely in Western Manitoba during the overnight time frame mixed in with the falling snow, travel should very well be difficult in those places especially up through the Riding & Duck Mountain's. 

Map mentioning blowing snow through the day tomorrow

One thing that will be noticeably different tomorrow will be the switchover to a northerly wind that will bring in the seasons first and coldest airmass for Manitoba. Northerly winds will result in Temperatures of -20C and colder, creating windchills of -35C to -40C. The winds will allow for blowing snow to develop on all major roads and highways likely resulting in a few travel problems The culprit? A sharp coldfront, that will move through overnight tonight from the North. (As seen as a blue line with spikes on the map, arctic air coming straight south behind it.)


This will be the coldest batch of air that we will receive in recent memory, overnight lows of minus 30C or colder will be very likely in the time frame through next week. Warming temperatures can be expected for the first week in February ie) after next week.

Back into Business this week!

After a long wait blog posts will return as expected with a review of 2012 as a whole, and a look back at our past couple weeks in terms of weather. I have been sidetracked and very busy with the holiday's and getting back into the routine of going to school and work, this in fact has been the longest time that I have waited to post and hopefully it won't happen again anytime soon. So see you all soon!
