This front will bring showers along it. At this point, amounts do not look significant, with highest amounts expected north of the Trans-Canada. They will reach Winnipeg by late morning and only last perhaps an hour or so. 1-3 mm is expected with locally higher amounts possible. Behind the front, we will see some glimpses of sunshine this afternoon. Winds will veer to the north/northwest and become sustained near 40 km/h this afternoon.
A shot of unseasonably cold arctic air behind this front will make for a very chilly Mother's Day weekend. On Saturday, highs will struggle to exceed 5°C with highs only expected to reach 6 or 7°C. At least skies will be fairly clear, but it will still remain breezy from the northwest making it feel only colder than it actually is. Sunday will be a transition day as a MUCH warmer air mass starts moving in from the west. Nonetheless, highs in the low teens are expected on Mother's Day, still a good 5-8 degrees below normal.
As the warmer air moves in there may be a band of light showers Sunday night along the warm front, but if that does materialize, it does not look heavy at this point.
Temperatures will skyrocket on Monday as the real warm air moves in. Highs between 22 and 24°C are expected in Winnipeg. The warmest will be along the US Border in southwestern Manitoba where highs in the high 20's are expected. Unfortunately, it may be a windy day, but with temperatures like that we wont complain ;)
Tuesday may be the warmest day of the week in the RRV and southeastern Manitoba. Highs in the high 20's are definitely possible. In addition, it looks like we may even start pumping in some higher humidity from the south. It'll feel like summer! This increased humidity along with a low pressure system moving through the province could create our first good thunderstorm chance of the season. This is not entirely certain yet and models have been differing on this possibility, but I'll be sure to keep you all up to date on it.
