Windy Morning! Cold Tonight With Snow Tomorrow...Dec 18th

  • Snow Update (3:30 pm PT)
  • Looking more and more likely that tomorrow evening through Friday morning will be a big snow event for Vancouver. Some indications put snowfall amounts as high as 10-15 cm. At this point I'm thinking a lot of it will be heavy and wet so more like 5 cm but that will make for one messy commute Friday morning,

    Oh and Seattle has issued a Winter Storm Warnings - I bet EC will issue something soon for Vancouver.

    By the by, these dark clouds we are seeing right now bringing isolated ice pellets to parts of the North Shore, Vancouver, Victoria. Clearing out tonight

  • Northwesterly winds have cleared skies out, are dropping temperatures and bringing some strong gusts 
  • Wind warnings were in place for Metro Vancouver this morning but have now ended. Gusts were up to 57 km/h at YVR
  • Meanwhile the cold front that moved through the south coast yesterday, continues to track across the interior today - 10 cm snow expected for the southern highway passes before tapering off tonight
  • Winds will ease for Vancouver this afternoon in mainly blue skies...a few isolated and brief snow showers may skip down from the north this afternoon..especially towards the valley
  • Temps tonight will drop down to -2 to -5 across the south coast - and only up to 1 or 2 tomorrow afternoon
  • Thu will start off with blue skies but an approaching warm front will spread in high clouds ahead of teh system tomorrow afternoon
  • As the moisture moves in Thu night, it may start off as a couple cm of snow for Vancouver, before changing over to rain Friday. Some areas could see 2-5 cm meaning winter driving Friday morning on the roads
  • Temps will begin to warm up Friday afternoon - back to seasonal but with a moist westerly flow keeping the showers in all weekend
Winds & blue skies the story today - Cold & possible snow story tomorrow

Temps Falling Right Across Western Canada
  • After hitting +8 yesterday in Calgary with Chinook winds, temps have plummeting and are now sitting at minus 14, -22 with wind chill!
  • Thanks to an arctic cold front-  Edmonton is dropping down to below -20°C this afternoon
  • Saskatchewan temperatures are also falling today and will be around -18°C this afternoon in Regina and below -20°C in Saskatoon
  • Winnipeg tops out at a balmy -11°C but looking to get some fresh snow tonight

Atlantic Canada Winter Storm
  • The Maritimes are getting hit with a full on winter storm right now - winter storm warnings in place for the eastern Maritimes for up to 15 cm by this evening 
  • Strong winds are also resulting in blowing snow causing reduced visibilities. And for some, warming is moving in tonight for a changeover to freezing rain and ice
  • Meanwhile the storm continues to track towards Newfoundland, snow already starting for the western half - snow and blowing snow will spread to the remainder of the island by this evening.
  • Winter storm warning in place for 15-40 cm (higher amounts to the west) by Thursday morning. 
  • In addition, strong southeasterly winds gusting up to 100 km/h will develop ahead of the storm and shift to strong northwesterly winds gusting up to 110 km/h overnight. The fresh snowfall and strong winds will cause poor visibilities in blowing snow.

And Another TWO for Ontario This Weekend - High Impact
  • A special weather statement is on place for southern ON & QC for significant winter weather Friday and into this weekend.
  • Several disturbances originating in Texas are expected to move towards the Lower Great Lakes starting Friday. 
  • The first system is expected to spread precip in the form of rain/ice/snow/all of the above into Southwestern Ontario Thursday evening and through the remainder of Southern Ontario by Friday morning. Still a lot of uncertainty in what exactly will be falling - but it will be messy
  • Another more potent storm approaches Southern Ontario this weekend. The next storm system is expected to tap into moisture from the Gulf of Mexico and has the potential to bring a significant and extended period of freezing rain across Southern Ontario late in the day on Saturday through Sunday.
  • Big travel weekend for people so these two storms will have high impact. These storms will be snarling travel in the eastern US as well for all the major hubs
