Snow arrives with Slightly Below Seasonal Weather For the weekend

 

This update will be brief albeit there is a lot to talk about for our weather this weekend, one of them being another clipper system moving into the region which will bring another round of snowfall (above) which will likely create for another day of impactful weather. I was looking over the forecast discussions from Environment Canada and they mention that the snowfall tomorrow may have more snow water equivalent than earlier in the season. EASTERN PRAIRIES...CLEAR SKIES AND COLD TEMPERATURES WILL GIVE WAY TO  

APPROACHING LOW FROM NORTHERN ALBERTA THIS EVENING. THE LOW WILL  
TRACK SOUTHEASTWARDS OVERNIGHT, PUSHING A SWATH OF SNOW THROUGH THE  
NORTHERN GRAINBELT OF SASKATCHEWAN OVERNIGHT AND INTO CENTRAL AND  
SOUTHERN MANITOBA THROUGH SATURDAY. THE LOW WILL BE MOVING QUICKLY,  
LIMITING SNOWFALL AMOUNTS, BUT WITH HIGH SLRS AND MID-LEVEL  
INSTABILITY, POCKETS OF HIGHER SNOWFALL AMOUNTS ARE LIKELY. GENERAL 
 
ACCUMULATIONS OF 4 TO 8 CM ARE EXPECTED.”” 

What this means is that there will be a period of heavy snowfall from the late morning into the late afternoon period. Snow will likely accumulate to 4 to 8cm with as much as 10cm in some locations. Snow and blowing snow will also likely be a hazard as winds gust to 50 to 60 km/h. Snow will clear by the early evening hours, with gusts of 60km/h likely in the southwest in the evening on Saturday. Temperatures for the weekend will warm up into the mid to high minus single digits this Saturday and Sunday, with temperatures between (-4C and -9C) and our overnight lows between (-5C and -16C). Windchill values on overnights will likely sit in the mid minus teens to low minus 20’s (-15C to -22C), a few areas might see low windchills around -30C). 

There are some signs of warmer weather filtering in for the week Monday into Friday, with temperatures sitting in the low minus single digits and a few degrees above zero for the first time, in over a month. This might help melt the current snowpack, hopefully not too quickly as lows look to remain below zero. 

Well update you more on Monday.
