Snow Squall Watch

Issued at 23:42 Monday 11 December 2017
Summary

Snow squalls are expected to develop. Under the snow squall bands, visibilities will be significantly reduced due to the heavy snow, and snow will quickly accumulate.

Conditions will become favourable for snow squalls on Tuesday afternoon in the wake of an Alberta Clipper and general snowfall tonight.

Snow amounts near 15 cm per 12 hours are possible in the strongest snow squalls Tuesday afternoon and Tuesday night.

Areas from near Barrie across Collingwood to Meaford have the largest chance of receiving snow squalls according to latest indications.

The Midland to Orillia areas will be near the northeastern edge of the lake effect snow bands in this case.

Snow squalls may continue into Wednesday.

###

Visibility may be suddenly reduced at times in heavy snow. Surfaces such as highways, roads, walkways and parking lots may become difficult to navigate due to accumulating snow.

Snow squall watches are issued when conditions are favourable for the formation of bands of snow that could produce intense accumulating snow or near zero visibilities.

Please continue to monitor alerts and forecasts issued by Environment Canada. To report severe weather, send an email to ec.cpio-tempetes-ospc-storms.ec@canada.ca or tweet reports using #ONStorm.

Special Weather Statement

Issued at 23:46 Monday 11 December 2017
Summary

Widespread snowfall likely tonight as an Alberta Clipper sails by. Lake effect snow squalls on Tuesday.

An Alberta Clipper is bringing snow to Central Ontario tonight. The snow will begin to taper off Tuesday morning with a general snowfall of 5 to 10 cm expected.

Although localized higher amounts of 10 to 15 cm are possible, snowfall warnings are not expected as amounts will be less than the 15 cm per 12 hour threshold required.

Poor winter driving conditions are expected to continue as a result.

On Tuesday, conditions will become favourable for the development of lake effect snow squalls in a stiff and cold northwest flow over Georgian Bay. Please refer to snow squall watches in effect for the regions near Southern Georgian Bay.

Environment Canada will continue to monitor this situation and update statements accordingly.
