The weather agency expects freezing drizzle to continue throughout the morning, ending by noon.
A rich layer of near surface moisture, combined with a stationary frontal boundary and temperatures between -5 and -10, are providing conditions favourable for freezing drizzle. On your Sun Valley Tire road report, as of 6:30 a.m. Monday, highways west of Highway 75 are partly ice or ice covered, with fair visibility in fog.
"As high pressure builds behind this the low, and a trough develops in the jet stream, temperatures will fall throughout the day, landing between -6 and -8 Monday afternoon," explained CMOS Accredited Weathercaster Chris Sumner. "Relatively cooler conditions than what we've had the last couple days will settle in for Tuesday and Wednesday, keeping in mind conditions will still be much warmer than what we usually have in January. As we head to the back half of the week, and into the weekend, the forecast models are indicating another shot of Pacific air will flow over the Prairies, and that will once again push temperatures up as much as ten degrees warmer than average."
Average daytime highs for this point in January are -13, with overnight lows of -23. Temperatures this week are expected to range between -5 and -10 for highs.
