Cold Arctic Air will plunge over the Great Lakes kicking up the lake effect snow machine for the entire district Thursday.

snow squall watch issued 6:28 pm  Environment Canada has now issued a statement about the pending snow squalls expected to develop overnight tonight and well into Thursday morning.

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.

A period of snow is expected Thursday morning, amounting to 5 to 10 cm of snow. Conditions become favourable for a period of lake effect snow squalls off Whitefish Bay Thursday afternoon into Thursday evening.

The snow squall band off Whitefish Bay is expected to meander slightly in a northwest-southeast orientation, resulting in possible snowfall amounts of 10 to 15 cm.

Environment and Climate Change Canada is closely monitoring the situation and will update messages as required.

Travel may be hazardous due to sudden changes in the weather. 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.

The first major snow accumulation always seems to take people by surprise, especially if you’re driving.

The time line for the snow squalls appears like this.

Flurries and snow showers developing around 7pm to 10pm Cloudy

After midnight : Snow showers – accumulation about 3cm

4AM  to 8AM – Heavy snow squalls expected – an additional 10cm

8AM – NOON Thursday – Frequent snow squalls / lake effect snow showers – 5cm

Thursday afternoon: Frequent flurries and cold.

The cold and snowy weather is expected to last through the weekend before a rebound to warmer (normal temperatures) developing by next week changing snow to rain showers as temperatures fall in the plus 6c range by early next week. No other snow event is in the cards just yet. The rest of November looks seasonal with overnight lows in the -5c range and daytime temps in the lower single digits on the plus side.
