Rain Rules the Morning—But Snow’s on Deck for Sudbury Tonight
It’s a classic Northern Ontario spring day in Sudbury: light rain, cool temps, and the promise of snow just waiting in the wings. As of 8:00 AM EDT at Greater Sudbury Airport, the temperature sits at 2.4°C, with light rain falling. Visibility is decent at 32 km, though a falling barometric pressure (100.6 kPa) signals more unsettled weather ahead.
Humidity is 73%, and winds are from the southeast at 17 km/h, giving the air a damp, chilly feel.
Today’s Forecast: Rain Through the Day with a Mild Push
Periods of rain are expected throughout the day as the system rolls through the region. Winds will shift to southerly at 20 km/h near noon, helping temperatures rise to a high of +8°C, which will feel relatively mild after the past few weeks. The UV index is low at 1, so leave the sunglasses at home and bring a raincoat instead.
Tonight: A Rain-to-Snow Switch as Temperatures Fall
The weather turns wintry again tonight as the rain gives way to snow after midnight. A 60% chance of rain showers dominates the early evening, but don’t let it lull you into spring mode—periods of snow will begin overnight as the low hovers around 0°C. Winds shift westward at 20 km/h, gusting to 40, making for slick, slushy roads by early morning.
Tuesday: Snowy and Windy—More Winter Than Spring
Snow continues through Tuesday, with northwest winds gusting up to 50 km/h and a daytime high of only +2°C. The wind chill will bring a bite to the morning hours, and flurries are expected to continue Tuesday night, with a low of –4°C.
Midweek Outlook: A Brighter, Colder Calm
Wednesday brings sunshine and a high of +3°C, a fresh but dry day. However, the clear skies come with a sharp overnight low of –10°C, reminding us that frost still rules the mornings.
By Thursday, the sun sticks around and temperatures climb to +8°C, offering a real taste of spring before clouds return Thursday night.
Historical Perspective: April 14 in Sudbury
Sudbury has experienced a mixed bag on this date—from balmy 20°C days to snowy flashbacks like today’s setup. The all-time record high for April 14 is 19.2°C, while the record low sits at –14.6°C. So today’s chilly, wet blend lands firmly within the “spring in Northern Ontario” playbook.
Wardrobe Wisdom
Keep your umbrella handy this morning and swap it for mittens by midnight. Today calls for a waterproof jacket, warm layers, and some weather-appropriate optimism. If you’re commuting early Tuesday, be prepared for icy roads and reduced traction.
Did You Know?
Sudbury’s unique geography—nestled in a basin surrounded by rocky hills—can trap cold air overnight, making it one of Ontario’s frostiest urban centres during spring. That explains those double-digit temperature dips after sunny days.
