A special weather statement flags possible multi-day totals above 75 mm before colder air brings a rain-snow mix Thursday

THUNDER BAY, Ont. — Nov. 3, 2026 – WEATHER – Thunder Bay and Kakabeka Falls remain under a special weather statement as one wet system departs and another approaches, raising the risk of ponding on roads and in low-lying areas through Thursday.

Environment Canada said in a statement issued at 9:21 p.m. EST Monday that multi-day rainfall totals could exceed 75 millimetres. The track of the next low and the axis of heaviest rain remained uncertain, and rainfall warnings could be issued.

Tuesday Nov 3 Mild with rain and drizzle

Thunder Bay and Kakabeka Falls have rain at times mixed with drizzle, with about 5 mm expected and morning fog patches dissipating. Temperatures hold near 13 C and the ultraviolet index is 1, or low.

Rain continues tonight, with another 5 to 10 mm. Thunder Bay’s northeast wind increases to 20 km/h before morning. Kakabeka Falls also develops a northeast wind of 20 km/h before it eases after midnight. The low is near 10 C in both areas.

Wednesday Nov 4 Heavier rain returns

Thunder Bay could receive 15 to 25 mm of rain and reaches 15 C. A northeast wind of 20 km/h eases early in the afternoon.

Kakabeka Falls expects 15 to 25 mm. A north wind increases to 20 km/h in the afternoon, with the temperature near 12 C. Rain continues Wednesday night, with a Thunder Bay low near 7 C.

Thursday Nov 5 Rain may mix with snow

Colder air arrives while precipitation continues. Thunder Bay expects periods of rain or snow and a high near 7 C. Kakabeka Falls and the nearby inland area should also see rain mix with snow, with highs generally near 6 C. Thursday night remains cloudy with a 40 per cent chance of rain showers or flurries and temperatures near 0 to 1 C.

Travel and drainage

Watch for water pooling in wheel tracks, at clogged drains and in low spots. Slow down where spray reduces visibility and give extra room to pedestrians.

The forecast does not establish that flooding will occur, but the special weather statement identifies low-lying areas as vulnerable.

Wardrobe

A hooded waterproof shell, waterproof boots and a spare dry layer will be useful through Wednesday. Add gloves and an insulating layer Thursday, when colder rain may mix with wet snow.

Weather trivia

A rainfall total of 75 mm equals 75 litres of water over every square metre. On saturated or poorly drained ground, that volume can collect quickly even without a short-duration downpour.
