MONDAY: LIGHT DUSTING OF SNOW, TEMPERATURES REMAIN MILD
Atlantic Canada will just see some light snow and flurries Monday, as a weak system continues to push east and most regions will see only trace amounts or less than 5 cm at most.
Temperatures will remain above seasonal, with most of Atlantic seeing daytime highs above zero. Southern areas of Nova Scotia will hover close to 5°C.
TUESDAY AND BEYOND: NEXT STORM WILL BRING IN BRIEF ARCTIC BLAST
A more significant system will move into the region late Tuesday afternoon and will first track through western New Brunswick. Accumulations of 10-15 cm of snow is expected for much of New Brunswick and as much as 15-20 cm could fall in Cape Breton through Wednesday morning. Halifax and areas to the southwest of it will see 2-5 cm of snow while east of the city could see amounts closer to the 10-cm mark.
The heaviest amounts will be in southwestern Newfoundland, where 20-30 cm of snow could accumulate through Wednesday afternoon, while 10-15 cm of snow is expected for the Avalon Peninsula during the same time period. Totals will be influenced by sea enhancement.
Winds will also be quite gusty overnight Tuesday, into Wednesday morning, particularly for Nova Scotia. Gusts could reach 70-90 km/h in southwestern portions, while parts of Cape Breton could experience winds exceeding 100 km/h.
Following the departure of this system, temperatures will drop considerably Thursday as a brief burst of cold air from the Arctic will return, but temperatures will bounce back by the weekend.
