snow squall
Snow squalls today through Tuesday morning.
What:
Heavy lake effect snow. Total amounts of 15 to 30 cm, with locally significantly higher amounts possible.
Locally reduced visibility in blowing snow.
When:
This morning through Tuesday morning.
Additional information:
Lake effect snow off Lake Huron is expected to continue impacting Lambton County and possibly locations near the eastern shore of Lake Huron this morning. Snow squalls may extend towards Lake Erie as well at times.
Northerly winds are expected to become northwesterly late today into early Tuesday. As a result, lake effect snow will impact areas to the east and southeast of Lake Huron. There is a potential for very heavy accumulations and intense snowfall rates tonight into Tuesday morning, particularly if lake effect bands become stationary.
Lake effect snow is expected to taper in intensity by Tuesday afternoon.
###
Travel may be hazardous. Visibility may be suddenly reduced to near zero at times. Roads and walkways may be difficult to navigate due to accumulating snow.
