A Slick and Slushy Start to Saturday
Sioux Lookout – WEATHER – Starting your Easter weekend Saturday you are waking up to a chilly, damp morning, with the temperature sitting at -3.0°C as of 6:17 AM.
A light freezing drizzle is creating slippery surfaces, making early errands a careful affair. Humidity is nearly maxed out at 99%, and the dew point is just a hair below the actual temperature, giving the air that bone-deep chill.
Visibility is reduced to just 3 km due to the drizzle, and winds from the north-northeast at 6 km/h are contributing to a wind chill of -5°C—though it feels closer to -8°C earlier in the morning.
The barometric pressure is on the rise at 101.8 kPa, a hint that conditions will start to improve through the day. This morning comes with a 40 percent chance of flurries and continued risk of freezing drizzle, but by this afternoon, skies will break into a mix of sun and cloud as the day inches toward a high of +4°C. The UV index is a modest 3, so while the sun may make an appearance, it won’t be intense.
Clearing Skies, but a Cold Night in Store
Tonight, the clearing trend continues, with skies opening up completely. Winds will remain light—up to 15 km/h—but the temperature will drop to a chilly low of -7°C. With light winds and a dry atmosphere, the wind chill will feel closer to -12°C overnight. It’s a great night for stargazing, but only if you bundle up like it’s still January.
Sunday Serves Up Sunshine and Spring Vibes
Sunday brings a welcome shift in mood and temperature. Sunshine will dominate the day, with winds shifting to the south and ramping up to 20 km/h, gusting to 40 by late morning. The downside? A frosty start, with a wind chill of -10°C early on. But as the sun climbs higher, the temperature will follow suit, reaching a pleasant high of 12°C. The UV index ticks up to 5, so sun protection is back in play for anyone enjoying time outdoors.
Cloudy periods will return overnight Sunday with a low of -2°C—not bad at all compared to recent nights.
More Mildness on the Way
The trend of bearable spring weather continues into Monday, with a mix of sun and cloud and a high of 11°C—arguably perfect jacket-weather. Monday night will remain dry but cool, with clouds building back in and a low of -2°C.
Tuesday takes a slightly greyer turn with overcast skies and a high of 8°C. The night stays cloudy as well, but temperatures hold steady with a low of +1°C—no frost warnings in sight, at least for now.
What to Wear
Today calls for caution and layers. Waterproof, insulated boots are a must in case that freezing drizzle hangs around a bit longer. Bundle up with a warm coat, gloves, and a hat to cut through the wind chill, especially in the early hours. Sunday and Monday are perfect for lighter layers—think fleece or spring jackets—and by midday Sunday, you might even want sunglasses and sunscreen.
