My thoughts on potential weather events into next week
November 15, 2017; 4:18 PM
Forecast modeling for the short term is still at odds, especially in terms of timing of fronts and storms. We are leaning more toward the European model solutions compared to the American models.
1. Short period of lake-effect snow this Thursday downwind of the eastern Great Lakes. Primary wind direction from the Northwest. It will also turn quite windy throughout the Great Lakes region on Thursday.
2. Potential for a period of steady, accumulating snow Friday night through Saturday evening from near Sault Ste. Marie to Sudbury.
3. We may see a longer duration period of heavier lake-effect snow downwind of the Great Lakes Saturday night into Sunday. The primary wind flow may be more from the West-Northwest.
4. Another shot of Arctic air is likely to spread southeastward from northern and central B.C. through the southern Plains early next week.
5. We have to watch for the possibility of a period of upslope snowfall over the southern half of Alberta Monday into Monday night. This is still high uncertainty.
6. Another round of strong winds is likely for Ontario and Quebec Saturday night into Sunday.
7. Another in a series of storms will likely bring heavy rain and high winds to southern B.C. Saturday evening and night. Potential for substantial snowfall in the coastal and Rocky Mountains of B.C. Saturday night into Sunday.
8. Watching to potential for heavy rainfall over southwestern B.C. Tuesday night into next Wednesday. This storm may be associated with an atmospheric river of moisture, which could mean flooding for some areas. The same storm may also bring high winds to the coast and mountains.
The map below shows the projected temperature departures for the 5-day week ending next Friday. Most of the models have trended less cold in the east for next week.
