WEST CARLETON – Environment Canada is calling for 30 to 50 millimetres of rain all day Christmas Eve (Dec. 24) in to Christmas day.
“Rain is forecast to develop over eastern Ontario Thursday (Dec. 24) morning,” Environment Canada issued in a special weather statement this morning (Dec. 23). “This rain is then expected to continue through Thursday night. Total rainfall amounts of 30 to 50 mm are likely with this event.”
So much for a white Christmas.
“By Friday morning, Christmas Day, the rain is expected change to scattered flurries or periods of snow as temperatures drop to below the freezing mark,” Environment Canada said. “A few centimetres of snow will be possible.”
This rain is associated with a strong low-pressure system that will approach the area from the south Thursday.
“There remains some uncertainty as to the exact track of this low-pressure system,” Environment Canada said. “Areas closer to and including central Ontario may transition to snow earlier than currently forecast, changing associated precipitation amounts.”
Localized flooding in low-lying areas is a possible as the frozen ground has a reduced ability to absorb rainfall.
“Rainfall Warnings may be required as the event draws closer,” Environment Canada said.
