An Alberta clipper moving through the province yesterday tapped into Pacific moisture drawn over the area, leading to showers throughout much of Sunday.
"Freezing drizzle was reported in some areas in the early morning hours, but by mid-morning had switched over to just rain," said CMOS Accredited Weathercaster Chris Sumner. "Our Rainwatchers have indicated those light showers led to accumulating rainfall over the last twenty-four hours."
Sumner noted, Southern Manitoba was quite fortunate to see temperatures remain around or slightly above zero for much of the day Sunday, because it kept the precipitation as rain rather than freezing rain. "It also prevented highway conditions from becoming challenging, bare and wet was the general trend from mid-morning Sunday through the remainder of the day."
Several weather advisories were issued over the weekend but for the time being, there are no watches or warning in effect. Power was out for several hours in many parts of the area yesterday thanks to the conditions but for the most part, all was restored by late afternoon.
Meanwhile, for Monday as the low-pressure system exits Southern Manitoba, there is a good chance of freezing drizzle or flurries throughout the day, with the temperatures remaining around zero.
The following totals are courtesy the Manitoba Ag Weather Network and Environment Canada and are for November 5th through 5 a.m. November 6th, unless otherwise stated:
Riverton - 9.0mm
Selkirk - 8.9mm
Carman - 7.6mm
Steinbach - 6.5mm
Arborg - 6.2mm
Winnipeg (airport) - 6.1mm (Nov 5th only)
Starbuck - 5.4mm
Plumas - 5.0mm
Portage - 3.9mm
Elm Creek/Kane - 3.9mm
Morris - 3.5mm
Morden - 3.4mm (Nov 5th only)
25mm - 1inch
Looking ahead to the remainder of the week, Sumner points to additional freezing rain, rain, and snow chances.
"Another low-pressure system expected to track along the international border Tuesday could lead to similar conditions as Sunday," he explained. "Similar to Sunday's clipper, how this low tracks will dictate which regions are more likely to see rain, freezing or snow. At this point, the closer to the border you are, the more likely it is you will see rain. The further north, the more likely it will be a couple of degrees cooler, just enough to be a snow-rain mix, or just snow. With that said, there are indications, that much of Southern Manitoba will see a snow/rain mix at some point Tuesday afternoon into the evening hours."
Sumner added there may also be a weak disturbance that moves through Wednesday night to Thursday which could also bring a flurry or two, but no major accumulations are expected from any of the systems this week.
"High pressure starts building into the area Thursday, meaning a return to sunshine and drier conditions," he said. "We're expecting sunshine and seasonal temperatures for the start of the weekend, with slightly above average daytime highs possible for next week. Remembrance Day on Saturday is looking sunny, with highs between +1 and -1."
Averages for this time of year are +2 daytime and -6 overnight.
