Rain Turns To Snow Later Tonight


Rainy and mild weather today followed by a quick return to winter tonight.

A deep low pressure area tracking from northern lower Michigan across Northeastern Ontario today into Northwestern Quebec by this evening has brought a large area of rain and patchy fog with it to the regions, with most areas expecting to receive 20 to 30 mm by this evening.

Special weather statement in effect for:

  • Agawa – Lake Superior Park
  • Sault Ste. Marie – St. Joseph Island
  • Searchmont – Montreal River Harbour – Batchawana Bay

The low will drag a sharp Arctic cold front across the regions this evening, causing temperatures to drop to below freezing and the precipitation to change over to snow. Most regions will receive 5 to 10 cm of snow by the time it tapers to scattered flurries Tuesday. A few locally higher snow amounts of 10 to 15 cm are possible.

Strong and gusty winds are also expected in the wake of the cold front, especially near the north shore of Lake Huron where a few gusts of 70 to possibly 80 km/h are expected.

Driving conditions are expected to become hazardous tonight as the precipitation changes over to snow. Untreated surfaces may become icy and slippery as the temperature drops below the freezing mark tonight. Low visibilities may also occur in snow and local blowing snow.

The snow will move out of the regions by Tuesday night as the low pressure centre moves away.
