Drizzle and rain taper from west to east Tuesday, with fog and sub-zero overnight wind chills before a brighter Wednesday

THUNDER BAY, Ont. — Nov. 3, 2026 – A wet start will give way to improving conditions across many remote Northern Ontario communities Tuesday, but damp surfaces, fog and a quick overnight freeze could complicate local roads, airport access and other exposed travel routes.

Environment Canada’s 5:30 a.m. EST forecast cycle showed no active watches, warnings or advisories for the eight communities in this report. Forecasts for Ogoki Post and Marten Falls First Nation use the official Fort Hope–Lansdowne House–Ogoki forecast zone.

Weather trivia

One millimetre of rain deposits one litre of water on each square metre of level ground. Even modest rainfall can therefore leave substantial water on poorly drained or frozen surfaces.
