SPECIAL WEATHER STATEMENT – CALEDON AND SURROUNDING AREA – 8:00am Dec 21

A tale of two winter storms.

From Southern Lake Huron to Hamilton and south to Lake Erie, dense fog patches are a concern this morning. Visibilities may be as low as 200 metres and will improve later this morning.

Over areas from Southern Lake Huron through the Greater Toronto area and eastward to Kingston and the St. Lawrence River, periods of freezing rain are occurring. Freezing rain will taper off or change to drizzle or freezing drizzle this morning. Please refer to the freezing rain warning which is in effect for these locales.

Further north from Northern Lake Huron through Barrie and east of Georgian Bay to the Ottawa Valley, precipitation has fallen mainly as snow and ice pellets.

After a brief break this morning, another more potent winter storm from the United States will approach Southern Ontario this afternoon. An ice storm will be possible across a large swath of Southern Ontario. Significant rainfall is likely for the Windsor area, where a rainfall warning has been issued. Significant snowfall and ice pellets are expected from Northern Lake Huron to the Ottawa Valley. Snow and ice pellet amounts may reach 10 to 15 cm.

This storm will move out of Ontario Sunday night or early Monday, followed by a few days of calmer weather.

There is still uncertainty surrounding the exact position of the storm track. Any change in the storm centre’s track will affect precipitation amounts and type. However, it is very likely that holiday travel will be significantly impacted.

Travellers should be prepared for dangerous winter travelling conditions. Untreated roads and sidewalks may become icy and very slippery especially in areas that receive extended periods of freezing rain. Power outages may also be an issue. We continue to recommend watching future forecasts and taking the necessary precautions.
