Statements

3:20 PM EST Monday 22 December 2014
Special weather statement in effect for:

  • Greater Sudbury and vicinity

Significant weather for Christmas.

On Tuesday, there is a threat of some patchy freezing rain across portions of Northeastern Ontario. A freezing rain warning has already been issued for Sudbury and North Bay. However, a more significant weather system is expected for Wednesday and Thursday.

Over Northeastern Ontario, the most significant precipitation is expected to arrive during the day on Wednesday as a strengthening weather system from the United States moves into the province. As temperatures will likely be above the freezing mark, the precipitation is expected to be in the form of rain. The exception will be for areas farther northwest from Chapleau to Timmins where temperatures may remain cold enough for precipitation to remain in the form of snow. There will also be a threat of freezing rain in these areas.

As colder air moves in behind the system, rain is expected to change to snow during the overnight hours or early Thursday morning. Significant snowfall amounts are likely, especially for areas that do not change over to rain. Amounts in excess of 15 cm are possible for locations such as Chapleau, Timmins and Gogama. In addition, gusty winds will likely result in local blowing snow on Thursday. Watches or warnings may be required as the event draws nearer.

For areas such as Sudbury, North Bay and Earlton, 15 to 25 mm of rain are possible followed by a few cm of snow and strong winds on Thursday.

There is still considerable uncertainty regarding the exact evolution of this system. This bulletin will be updated as more information becomes available.
