Env. Canada: January thaw and quick freeze for Almaguin, North Bay

NORTH BAY-ALMAGUIN — A special weather statement is in effect for Bayfield Inlet – Dunchurch, South River – Burk’s Falls, North Bay – Powassan – Mattawa and West Nipissing – French River areas.

According to the statement for Almaguin, issued at 5:33 a.m. on Thursday, Jan. 11, mild and rainy conditions are expected over much of southern Ontario today, tonight and into Friday. The rain is expected to be patchy and light for much of today, but may become more widespread tonight and into Friday. A general rainfall of 10 to 20 millimetres appears likely, although some areas may see higher amounts. This rainfall in combination with the melting snowpack may result in pooling of water on roads and low-lying areas.

A very strong cold front will cross the region from northwest to southeast on Friday bringing an abrupt end to the mild spell. Rain will quickly transition to snow, with a risk of brief freezing rain during the changeover. Snowfall amounts are expected to be limited to a few centimetres.

With the much colder air moving in on Friday, icy conditions on roads and sidewalks are likely due to the freezing of residual water from either melted snow or rain.

According to the statement issued for North Bay and area at 4:54 a.m., a significant January thaw with fog and rain is expected today. Rain will change to snow tonight with a hard freeze.

With the mild temperatures over the existing snowpack, dense fog patches are likely across much of northeastern Ontario today. Visibility may occasionally be reduced to near zero.

Periods of rain are also expected, particularly later this afternoon and into tonight. Average rainfall amounts are likely to be below the winter rainfall warning criteria of 25 millimetres in 24 hours. However, the criteria may be approached or reached in some places. Environment Canada will monitor this situation closely.

A very strong cold front will cross the area tonight. The front will reach the eastern shore of Lake Superior early this evening and track eastward to cross the North Bay area a few hours before dawn.

Following the passage of the front, rain will change to snow and there will be a hard freeze as temperatures plummet. There may also be brief freezing rain during the changeover.
