Southern Manitoba will continue to experience a warmer than average weather pattern this week, as a westerly flow remains in place.
Wednesday: Will start off clear, and throughout the day a southerly flow will strengthen with a area of high pressure in northern Ontario and a low pressure system in Minnesota. This system will gradually move east northeast into the province then. As a result, sunny skies are expected for the day on Wednesday, mainly cloudy skies are expected in extreme southeastern portions of Manitoba however. Temperatures for a majority of the day, will soar into the mid to high teens, with the Manitoba lakes only getting into the low to high single digits. Heading into the evening, much of southern sections of Manitoba except the southwestern sections will see cloudy skies as a area of low pressure in the northern plains moves into northeastern Minnesota. This batch of cloudcover will lift north into the overnight. Overnight lows for a majority of Southern Manitoba will drop into the low to mid single digits. Forecast: Night: Winnipeg: Cloudy, low +5C. Brandon: Clear, low +1C. Dauphin: Clear: low +3C.
Thursday: Calm weather is expected for Thursday. A Area of low pressure will be situated off to the east. Mostly cloudy skies are expected for Southeastern Manitoba during the morning and afternoon hours and for the remainder of the day. I am also expecting a chance for showers in extreme south eastern portion of Manitoba for the early afternoon hours. No other precipitation is expected for the day. Temperatures however for the day on Thursday will differ from Westec East, areas in Southeastern Manitoba will see temperature is only rising into the high single digits near 10°C. Areas along the line to the west of portage Laprairie north to south will see temperatures in the mid to high teens. Result of the lower temperatures in the south east will be the cloud that will be quite thicker than areas in the southwest part of the province. Heading into Thursday we’ll be on the eastern edge of an area of low pressure that will be in NW Ontario. bringing along with it a narrow but potent band of showers in the evening in areas of South Central and Southeastern Manitoba. This will likely persist into the overnight bringing upwards of 5 mm of rainfall for areas along the line Winnipeg east to the Ontario border. There is a chance this could completely miss areas of South Central and Southeastern Manitoba , if that is the case mostly cloudy skies will be expected overnight into Friday. Overnight low temperatures will be quite chilly sitting in the low single digits with only a few areas getting around 5°C.
Day: Winnipeg: Cloudy, high 10C. Brandon: Sunny high 16C. Dauphin: Sunny high 15C.
Night: Winnipeg: Cloudy, 60 % chance of showers. Low +4C. Brandon: Increasing cloud then cloudy. Low +4C Dauphin: Cloudy, low +4C.
Friday: The day will start off cloudy thanks, to an area of low pressure sitting off all northwestern Ontario. A fairly wide swath of showers is possible in areas of extreme southeastern Manitoba and portions of the white shell. Heading into the late afternoon hours some clearing should occur in areas of southwestern Manitoba. Clearing trend will continue into the evening hours. Temperatures in the areas of southwestern Manitoba will reach low teens. Temperatures however in south eastern Manitoba will only reach the mid to high single digits. Of note will be the precipitation in areas of Southeastern Manitoba. Heading into the evening hours the rainfall should shift over to moderate to heavy snowfall for areas just to the west of the Ontario border I am only expecting about 2 to 5 cm of snow fall to occur overnight. Clear skies are expected overnight into Saturday as a result of temperatures will drop drastically for areas that do not have overnight cloud. Temperatures will drop in to the low minus single digits overnight in areas of Southeastern and south western Manitoba the only exception being the white shell and parts of eastern Manitoba getting overnight lows in the low single digits, by a couple degrees below zero.
Day: Winnipeg: Mainly cloudy, high 8C. Brandon: Mainly cloudy, then clearing by the afternoon. High 12C. Dauphin: Cloudy, then clearing by afternoon. High 11C.
Night: Winnipeg: Clear, low -2C. Brandon: Clear, low -1C. Dauphin: Clear low 0C.
The weekend: This is where the weather forecast gets a little bit complicated I have been looking at some of the weather models and it looks like an area of low pressure will move through the region on Saturday and Sunday. However models are differing on precipitation timing and amounts as well as the precipitation type. It looks like there is a possibility for rain as well as snow on the weekend we will keep you updated on this and let you know on Friday about the potential event. Temperatures will of course continue to use it in the low to mid single digits with one or two of the days seeing some temperature in the teens.
