Quick update... I will have a more complete write-up later today. You can also follow my comments about the ongoing storm through my twitter @BrettAWX
1. I am still fairly happy with the snow forecast map that I drew up from home yesterday afternoon (below). The storm is fairly behaved so far in terms of the track, though we did have a bit of a surprise band of snow that went through our neck of the woods down here in central PA this morning and they canceled school.
2. Still looks like the Montreal area will be on the snow/mix/rain line Wednesday morning, so any shift in the storm track could have major implications to the forecast.
3. The south wind is going to be a major issue for coastal New England then the Maritimes Wednesday/Wednesday night. I can see gusts anywhere from 80 to 105 km/h, with the highest gusts along the coast and over the usual windy areas.
4. Rainfall amounts will average 40-80 mm with this storm for many locations in the Maritimes.
5. I will draw up a map later for the Ontario lake-effect snow behind this storm for Wednesday/Thursday.
A warm first half of summer for a majority of Canada.
Fast, west-to-east jet stream pattern across southern Canada into next week.
Clues to the long range over the next several weeks across North America.
Potential for significant rainfall over southwestern Alberta late this week into the early weekend.
A strong, upper-level storm system will bring significant rain, severe thunderstorms and much cooler air to parts of western and central Canada into early next week.
Latest ideas on the weekly long range through the end of this month.
