Snow squalls arrive right on time last night and are behaving as expected (what a surprise!) They dumped a little snow around Sault Ste. Marie overnight before migrating north of the city. This morning that are impacting regions north of Batchawana and could stay in that region for the next 36 hours. This brings a possibility for some locations, likely near Montreal River, receiving over 30cm of snow!
Squalls have also arrived on Manitoulin and Highway #17 corridor east of Iron Bridge. These regions will also see an extended period of squalls for the next day and a half. Later today squalls are expected to move a little more west; this will bring regions south of Laird Hill like St. Joseph Island, Desbarats, Bruce Mines and Thessalon into the action with upwards of 20cm of snow by late Saturday.
Be aware that when you are looking at radar that many of the squalls that are away from the radar station are not detected. The radar scan passes over the low-lying squalls and miss the action entirely. The image below shows the radar shot from Montreal River this morning. You can see that the nearby squalls show up nicely but only a hint of the squall action east of Iron Bridge is showing up….
