Big Snowfall, Low Visibility – Winter Isn’t Finished Yet
Geraldton and Greenstone face a Winter Weather Advisory with up to 15 cm of snow expected today and tonight. Travel conditions will quickly deteriorate
Geraldton-Greenstone, ON – Sunday, March 23, 2025 – Winter seems to have missed the memo about spring. A Winter Weather Travel Advisory is in effect today for the Geraldton, Longlac, and Caramat areas, as a vigorous weather system barrels through northwestern Ontario. With up to 15 cm of snow expected, visibility will be reduced, roads will be slick, and travel plans may need a rethink. Time to fire up the snowblower… again.
Current Conditions – A Frosty Start Before the Storm
At 5:00 AM EDT, it’s an eyebrow-freezing -24.5°C at Geraldton Airport, under clear skies with calm winds. The dew point sits at -27.5°C with humidity at 76%, while the barometric pressure is 101.9 kPa and holding steady. Visibility is currently 16 km, but that won’t last once the snow starts flying.
Wind chills this morning are a brutal -28, so frostbite is a real risk if you’re heading out without proper gear. You’ll want full winter battle armor: insulated boots, thermal layers, mitts, toque, scarf—the whole nine yards.
Today’s Forecast – Snow Begins, Visibility Drops
Skies will begin to cloud over this morning, with a 40% chance of flurries by midday. The real snow moves in this afternoon, with 2 to 4 cm expected before evening. Winds will shift from calm to east at 20 km/h later this morning, pushing the daytime high to a relatively mild -2°C—but don’t let that fool you. It will still feel closer to -6°C this afternoon, and -28°C earlier in the day thanks to the wind chill.
The UV index sits at a low 2 today—sunburns are unlikely, but snow blindness is still a thing, so sunglasses might come in handy during breaks in cloud cover.
Tonight and Monday – The Main Event
Snow will intensify tonight, with an additional 5 to 10 cm expected. Winds ease slightly, up to 15 km/h, and the temperature drops to a low of -8°C, with a wind chill around -12°C overnight. Travel could be treacherous, especially on rural roads and highways, so keep it slow and watch for sudden visibility drops.
By Monday, the snow will taper off in the afternoon after delivering another 2 cm. The rest of the day stays cloudy with a 40% chance of lingering flurries. Light winds and a high of -3°C will keep things chilly, with wind chills around -14°C in the morning and -8°C in the afternoon. The UV index remains low at 1.
Roads and Highway Travel
Looking Ahead to Tuesday – Still Cold, But Clearing
Tuesday keeps the cloudy skies around but should stay dry. The high will hover near -2°C, and skies will clear out at night, dropping the temperature to -14°C again. It’s a frosty pattern that refuses to break.
What to Wear – Layer Up Like a Pro
Today is all about layers. Start with thermals, add a mid-layer fleece or wool, and top it off with a windproof and waterproof outer shell. Mittens are warmer than gloves, and a neck gaiter or balaclava will be your best friend against the wind chill. If you must drive, have a shovel, blanket, and emergency kit at the ready—just in case.
Geraldton’s Snowy Past – March Extremes
On this day in Geraldton weather history, the warmest March 23rd saw a modest 6.8°C back in 1996, while the coldest plunged to -31.1°C in 1974. So while today’s -24.5°C is certainly cold, it’s not uncharted territory for the region. Just another chapter in the wild story that is spring in Northern Ontario!
