Dry But Foggy Week Ahead. Strong Inversion Remains

  • The foggy weather will continue for the next few days for the south coast thanks to that same high pressure system keeping moisture locked in at lower levels
  • Looks like low visibility with fog and mist will linger through much of the days before clearing later afternoons, but low stratus clouds will remain in place thanks to light westerly winds
  • We are dealing with a VERY strong inversion. Fantastic pictures of blue skies above 300m this weekend with temps in the low 20s on the local mountains! That inversion will continue through until at least mid week. In the fog, temps will struggle to get out of the single digits..
  • We are still on track to one of the longest dry stretches since 1991 - I'll take a look at the numbers for tonight. Part of the reason why it has been so dry (and foggy) is that our high pressure system is locked in place thanks to a 'blocking' pattern in the jetstream. our high can't move anywhere and weather across much of the country is stagnant.
  • Best chance for a break in the clouds comes Thursday with a little low pressure system that may sneak in to clear the fog out..but low confidence at this point
  • But dry forecast in the long range - we may not get any more rain this month!

First Snow of the Season for Many
  • Cold air has been digging in across parts of the Prairies and Ontario on the other side of BC's ridge bringing an early season snowfall to parts of Manitoba and northwestern Ontario.  
  • Snowfall warnings are in place for Geraldton, Manitouwadge and Hornepayne, where up to 20 cm is possible by Monday evening. 
  • Temperatures will also hover near the freezing mark and freezing drizzle has been reported across parts of southern SK. The Prairies are pretty much divided in half with most of Alberta on the warm side..and most of SK, MB & Northern ON close to freezing today
  • Wind chill values will be near -15 in southern Manitoba and between -5 and -10 in northern Ontario over the next couple of days
  • Cold winds will also bring the chance for lake effect snow showers through Tuesday in southern Manitoba.

Record-high smog in China closes schools, roads
  • Visibility shrank to less than half a football field and small-particle pollution soared to a record 40 times higher than an international safety standard in one northern Chinese city as the region entered its high-smog season.
  • One air quality index reached a reading of 1,000 in some parts of Harbin. According to the WHO, a level above 300 is considered hazardous and they recommend a daily level of no more than 20.
  • Winter typically brings the worst air pollution to northern China because of a combination of weather conditions and an increase in the burning of coal for homes, which usually starts around now

Hurricane Raymond strengthens off SW Coast of Mexico
  • Raymond, now a major Category 3 storm, continues to intensify just off the southwest coast of Mexico and will not have any impacts on the United States. 
  • Although Raymond is not expected to make landfall, the storm does post a threat to part of the southwestern coast of Mexico with heavy rain and hurricane-force winds through midweek.
