A storm will quickly intensify as it tracks up across Nova Scotia and eastern PEI later Sunday night. Computer models are still at odds with the exact track, which will be critical to the westward extent of the snow/rain line.
At this point, it appears that areas from Halifax on northeast will very likely see a short period of snow followed by rain as milder, low-level air moves in. A dry slot will also surge up through Nova Scotia putting a quick end to the rain late Sunday night.
Tough call for western PEI, northern and interior SW Nova Scotia as the snow may mix or change to rain for a period of time, reducing the snowfall potential. A slight eastward shift would likely mean all snow for most of these areas.
The highest probability of heavy snow and significant drifting will be from south-central New Brunswick to northeastern New Brunswick and then across the Gaspe Peninsula.
