Brief Warm up brings Blowing snow Risk

 This blog will not be your usual blog post , I’ll have a brief summary of the warnings issued for snow and blowing snow that will be accompanied by warm temperatures. As I have been feeling a bit under the weather lately with my mental health. 

Warm weather arriving, for tomorrow during the afternoon as we enter the warm sector where temperatures might surpass the 0C mark in some areas (Above). 

Much of southern sections of Manitoba is expected to see a brief but very warm period of weather, as a clipper system swings through which will bring the influence of the chinook that went across the Canadian prairie provinces. Temperatures will soar into the low to mid minus single digits with some areas getting as warm as the freezing mark or slightly above zero . 

Extreme cold weather arriving again for the weekend. (Above). 

There also appears that there will be a another surge of arctic air for the weekend, with calm weather but there will be a high risk for frostbite given that windchills will approach or even surpass -40C.

“Poor visibility in snow and blowing snow is expected or occurring in some locations.

An approaching trough of low pressure will result in increasing southerly winds late this evening into the overnight hours.

Winds will strengthen to 50 km/h with gusts to 70 km/h overnight tonight into Friday morning. These strong winds will cause reduced visibilities in blowing snow, especially in open areas overnight tonight into Friday morning. In addition, snow will begin falling by Friday morning, which will aid in reducing visibilities.

Southerly winds will ease by mid day with the passing of the trough but will quickly switch to northwesterly by late afternoon, which may cause further reductions to visibility on Friday evening.

Overall, 4 to 8 cm of new snow is forecast. An inverse temperature trend will also accompany the approaching trough, as temperatures will rise steadily tonight, reaching the mid minus teens overnight followed by falling temperatures tomorrow afternoon.

Travel is expected to be hazardous due to reduced visibility in some locations. Visibility may be significantly and suddenly reduced to near zero. Be prepared to adjust your driving with changing road conditions.

Blowing snow advisories are issued when winds are expected to create blowing snow giving poor visibility to 800 metres or less for at least 3 hours.

Please continue to monitor alerts and forecasts issued by Environment Canada. To report severe weather, send an email to MBstorm@ec.gc.ca or tweet reports using #MBStorm.“

  After the snow moves through much of southern Manitoba will again experience highs between -15C and -29C with windchills between -25C and -35C with overnight temperatures in the high minus 20’s and low minus 30’s windchills of -43C or more. Please dress warm and stay inside if you can .
