Colleen Bready's forecast: Mild, misty conditions continue Monday

CTV Morning Live Weather Update for Dec. 30, 2024 Daniel Halmarson has your Monday morning look at weather.

As we close in on the end of 2024, mild and misty conditions continue on Monday afternoon in southeastern Manitoba and northwestern Ontario.

As of early this afternoon, a fog advisory issued by Environment and Climate Change Canada (ECCC) remains in effect for those regions.

The weather agency said dense fog developed overnight in southern Manitoba. Fog banks continue to produce near-zero visibility in some areas. Conditions should improve this afternoon.

ECCC anticipates fog will linger longer in northwestern Ontario, possibly into this evening.

As the fog lifts in Manitoba, northwest winds will begin to sweep into the south that will flush out a stagnant airmass over the region, and along with it, the mist, fog, and drizzle we’ve seen over the past week or so.

This is related to an upper low over the Prairies that is starting to break down. As it does, light snow will fall across northern Manitoba today and tonight. There is the chance a few flakes will fly in the south, too.

Temperatures will fall across the north this afternoon as northwest winds increase but will remain well above normal for late December. This is in contrast to record-breaking daytime high temperatures in several northern communities on Sunday.

Daytime highs across the south will remain well above normal today, reaching the minus single digits. We will still feel the chill as northwest winds strengthen this afternoon and tonight. Mild temperatures will continue tonight.

The chance of periodic light snow increases in Winnipeg and across the south on Tuesday. Temperatures will be slightly colder with a forecast high for Winnipeg of -7 C.

If you’re heading out to celebrate New Year’s Eve tomorrow night, expect a cloudy sky and an overnight low of -11 C to ring in 2025.

For perspective, the normal daytime high for this time of year for Winnipeg is -13 C, while the low is -23 C.
