Above Seasonal Temperatures Returning

For those of you who have been patiently waiting for warmer weather over the past couple of weeks above normal temperatures and increasing amounts of humidity look to return to southern Manitoba as we start the week. (As seen in the photo below for Tuesday). 

Monday : A building ridge will be crossing into Manitoba on Monday which will usher in warming temperatures that will transition from being seasonable to above average for this time of year . For the day Monday expect winds to be out of the south with a mix of sun and cloud and high temperatures for the majority of the region reaching the mid to high 20s especially as you go towards south western Manitoba. Areas in the southeast will be more closer to 23°C to 25°C. I expect a high temperature of 25°C for Winnipeg and high of 29°C for Brandon. 

Monday Night:

There be a increasing clouds overnight into Tuesday resulting in more cloud cover by the morning. Overnight low temperatures will drop for the majority of southern Manitoba between 15 and 20°C as a result I expect a low temperature of 16°C and Brandon and low temperature of 17°C in Winnipeg. 

 Tuesday: expect a chance for showers and weak thunderstorms in the morning to early afternoon Hours in southern Manitoba. Given weak CAPE I don’t expect much in the way of severe weather for Tuesday. The shower is clear by early afternoon will be a mix of sun and cloud and fairly pleasant conditions. The only difference on Tuesday will be the temperatures, the majority of the southern half the province temperatures will be between 25°C and 35°C surpass 30°C with the dewpoints reaching 15 to 20°C it’s entirely possible that some areas may see Humidex values closer to 37C. I’m forecasting a high temperature of 31°C for Winnipeg and a high temperature of 31°C for Brandon. Because of the heat there may be a chance for a pop-up shower or thunderstorm in the afternoon this will have to be monitored. Winds will be light out of the south at 20 km an hour.

Tuesday night:

Temperatures will be a bit more comfortable, overnight lows are expected to be between 15 and 20°C, winds will also be light out of the south to south west.  It overnight low of 16°C can be expected for Winnipeg and overnight low of 17°C for Brandon.

Wednesday:

Will be one of the hottest days for the first half of the week, High temperatures for a majority of seven Manitoba will be in the 30 to 35°C range with some areas in the Interlake slightly closer to the 27°C to 27°C to 29°C range. The dewpoint temperatures in the southwest portion of Manitoba and possibly in the red river valley region will be in the 15 to 20°C 20°C range , which would bring the humidex values closer to 40°C and if the dew point manages to sneak into the low 20s to 22°C the humidex may end up closer to 44C in some regions (yet to be determined). Overall I expect a high temperature of 33°C for the city of Winnipeg and a high temperature of 34°C for Brandon with both regions seeing humidex values from 38 to 40C. Because there is an area of low pressure close to the Interlake region, there may be a threat for some thunderstorms in the afternoon with some of which may be severe (however the cap may inhibit thunderstorm development ) we will keep you updated on Manitoba weather centre for any threat of severe weather on Wednesday. 

The second half of the week into the weekend:

The rest of the week high temperatures will continue to see high temperatures in the mid to high 20s are also be a threat of severe weather on Thursday  as an area of low pressure moves through the southern portion of Manitoba. There may be a brief reprieve of unsettled weather on Friday before it returns for the weekend.
