A long wave trough stretching from one end of the country to the other is going to bring us a couple interesting weather events this week.
The trough acts as a highway along which weather systems develop and with the right dynamics, they will intensity and as they get steered by the upper air flow.
By this time tomorrow, an area of low pressure will have developed over southern Quebec. As this system approaches, we can expect snow to start late tomorrow over westernmost regions.
Because this system is expected to stay north of us, warm air will flood across our region early Wednesday, changing the snow to rain, with a brief period of ice pellets and freezing rain in the transition. Snow will be more significant across northern New Brunswick with 20 cm of more by midafternoon Wednesday.
NB: 10-15 cm late tomorrow evening and overnight into Wednesday AM; changing to freezing rain by sunrise, then rain around noon.
I think, given recent events, the Miramichi are deserves special attention. It looks like the snow will start around midnight tomorrow night and change to freezing rain by 9 am. I expect 3-4 hours of freezing rain before the temperature climbs above freezing. Having said that, it won't get much above 0; 1 or 2 degrees. Bathurst won't likely get much freezing rain, if any at all.
Northern NB: arrives just before midnight - 20-25 cm of snow; ends noon Wednesday
NS: 5-10 cm of snow starting after sunset - followed by ice pellets and freezing rain, then rain before morning. 5-10 mm of rain.
PEI: 5-10 cm of snow, starting just after midnight- followed by ice pellets and freezing rain by sunrise and rain by noon. 5-10 mm of rain.
Tomorrow night's system will pull the jet stream down and the next low will track further south. I don’t think anyone will be on the warmer side of this one! The low will slide south of Nova Scotia late Thursday. Things could change, but here's how it looks right now:
NB: 10-15 cm southern NB; 5-10 cm central, flurries if anything north.
NS: 5-10 cm; 10-15 cm Cape Breton Island.
PEI: 10-15 cm Thursday night.
