Clear Skies This Morning, But Clouds Are Plotting Their Weekend Comeback
SIOUX LOOKOUT & PICKLE LAKE – WEATHER REPORT – It’s a crisp and clear start to the day across Sioux Lookout and Pickle Lake, with mostly cloudless skies and the thermometer reading -4.1°C. While it looks peaceful out there, the wind chill is still making things feel like -11°C — a frosty reminder that northern Ontario likes to keep spring on a short leash.
Today’s Forecast – Sun-Soaked but Chilly Start
The early morning sun is putting on a cheerful show, and visibility is excellent at 24 km — perfect for spotting any stray moose or your neighbour finally shoveling that last bit of icy driveway. Winds are light from the south-southeast at 6 km/h, set to pick up slightly to 15 km/h by midday.
The barometric pressure sits at 102.1 kPa and is on the rise, signaling continued fair weather — at least for today. Humidity is at 85%, so the air still feels a little moist, despite the clear sky. We’ll reach a high of 9°C this afternoon, and the UV index will hit a moderate 4 — not scorching, but enough to warrant some sunblock if you’re outside soaking it up.
Foggy Nights and Cloudy Days – The Weekend’s Forecast Plot Thickens
Tonight brings clear skies early on, but cloud cover is expected to increase after midnight, setting the stage for patchy fog to develop by early Friday. Winds remain light at 15 km/h, and temperatures will dip to -4°C overnight with a wind chill near -8°C. It’s the kind of night where a hot drink and a cozy blanket win every time.
Friday kicks off with morning fog patches, which will gradually lift to reveal a mostly cloudy day. Highs will hit 11°C — warm enough to finally crack a window without freezing your toes. However, the UV index will be low at 1, so you can keep the sunglasses in your glove box. Friday night becomes murkier with a 30 percent chance of showers and a mild low of +3°C.
Saturday continues the cloudy theme with another 30 percent chance of showers and a springlike high of 13°C — time to start thinking about taking the BBQ out of retirement. The clouds stick around into Saturday night, keeping temperatures steady at +3°C.
Sunday keeps up the trend of unsettled skies with a 30 percent chance of showers and a slightly cooler high of 9°C. Sunday night flirts with wintry mischief again as the temperature drops to zero and there’s a 40 percent chance of either rain showers or flurries.
Monday brings more clouds and a continued 40 percent chance of mixed precipitation with a daytime high of +2°C. Monday night reminds us we’re not quite done with winter yet — cloudy skies and a low of -7°C return for a frosty finish.
April 10 Weather History – Sioux Style
Sioux Lookout’s warmest April 10 on record soared to a comfy 18.6°C in 1991. On the frosty end, the coldest April 10 was a biting -21.3°C, recorded way back in 1940. So, today’s high of 9°C? A respectable, middle-of-the-road kind of spring day.
Wardrobe Suggestions
Start your day layered up with a winter jacket, hat, and gloves — those wind chills mean business early on. As things warm up by the afternoon, you can switch to a lighter spring coat or fleece. And if you’re planning to be out after dark, keep the toque close at hand.
Weather Trivia – Fog’s Sneaky Side
Here’s a fun fact: thanks to their position within the Boreal Shield, Sioux Lookout and Pickle Lake often see spring fog form when clear skies meet cold ground and rising humidity. It’s nature’s version of mood lighting — just in time for the long weekend.
