Thunder Bay Weather Desk – Monday, February 16, 2026
Current conditions (as of 3:00 PM EST)
Thunder Bay – WEATHER – Thunder Bay is sitting at 7°C under partly cloudy skies—honestly, for mid-February, that’s practically a Valentine from Mother Nature. The air is dry with a 39% humidity and a dew point of -6.1°C, so it’s the kind of day where your lips notice winter even if the thermometer is being polite.
Winds are west-southwest at 16 km/h, gusting to 31 km/h, and the barometric pressure is 101.1 kPa and rising, a classic hint that today’s fair mood isn’t purely accidental.
Today and tonight
After a sunny stretch today with a daytime high near 3°C, clear skies settle in tonight and temperatures drop sharply to around -11°C. With that dry air and clearing trend, it’ll cool fast once the sun clocks out—winter loves a dramatic exit.
Tuesday into Wednesday: calm first, then the switch flips
Tuesday stays sunny with a high near 2°C, then cloud builds Tuesday night with a low around -7°C—the kind of “quiet before the shovel” setup. By Wednesday, snow arrives with a high near -4°C, continuing into Wednesday night with periods of snow and lows near -8°C.
Winter Storm Watch in effect: Tuesday night to Wednesday night
Environment Canada has issued a YELLOW WATCH – WINTER STORM, with moderate impact and high forecast confidence. The current call is for 10 to 20 cm of snow, with higher amounts possible over higher terrain, plus blowing snow and wind gusts up to 60 km/h that could drag visibility down fast—sometimes close to zero.
The heaviest snow is currently expected south of the City of Thunder Bay, but the track still has some uncertainty, meaning snowfall totals and the most-affected areas could shift.
If you’re travelling midweek, plan for slower going and sudden whiteouts in open areas. Roads and walkways may turn tricky, and delays—or even closures—are possible if conditions ramp up as expected.
The rest of the week: snow lingers, then a colder reset
Thursday continues with periods of snow near -4°C, then more snow at night around -9°C. Friday brings a 60% chance of flurries with a high near -4°C, then cloudy Friday night near -11°C. Saturday offers a mix of sun and cloud around -4°C, followed by a 40% chance of flurries Saturday night dipping to -13°C. Sunday keeps the theme going with a 40% chance of flurries and a cooler high near -6°C.
Wardrobe wisdom
Today’s mild reading is a bit of a trickster: go with layers—a lighter winter jacket or insulated shell, plus a hat that won’t fly to Duluth in the gusts. Tonight and beyond, switch to full winter gear: warm coat, insulated boots, and gloves that mean business. For the storm window Tuesday night into Wednesday, add snow-ready footwear and something that blocks wind—blowing snow has a talent for finding every zipper gap.
Weather trivia for Northwestern Ontario
Thunder Bay’s location near Lake Superior can be a snow “amplifier.” When cold air moves over comparatively warmer open water, the lake can help generate extra moisture and enhance snowfall downwind—one reason midweek systems can sometimes punch above their weight around the region.
