THUNDER BAY – WEATHER – Environment Canada has upgraded the weather alert for Thunder Bay to a Rainfall Warning.

The weather service says that there will be significant rain, coupled with mild temperatures which along with the melting snow will impact the Thunder Bay District and the City of Thunder Bay.

A Colorado Low will track across Northwestern Ontario from Wednesday evening on into Thursday evening.

Rainfall warning in effect for:

  • City of Thunder Bay

Environment Canada says, “Rain, heavy at times, is forecast to begin this evening. With temperatures hovering just above the freezing mark, a brief period of freezing rain is possible. However, temperatures will slowly rise tonight ensuring only rain by Thursday morning. Rainfall amounts in the 20 to 30 mm range are expected by the time the rain transitions to snow Thursday night. The heaviest rainfall amounts are likely near the north shore of Lake Superior through this period.”

The heavy rain will combine with mild temperatures in the high single digits to result in potentially significant snowmelt and localized ponding on streets and other low lying areas.
