Once again, the weather models did a pretty good job with the forecast. The heat and humidity moved in last weekend as expected and we did see several rounds of thunderstorms move through on Sunday and Monday of last week.

This forecast period will begin fairly unsettled as a broad area of low pressure tracks northeastward out of the western U.S. This low will bring clouds along with showers and thundershowers on Wednesday, with the risk of some heavier thunderstorms across extreme southern portions of Manitoba. This low is forecast to move off to the east by Thursday morning, allowing for a mix of sun and clouds on Thursday, with daytime highs expected to be in the mid-20s.

A weak area of low pressure is then forecast to track across south-central regions of Manitoba on Friday, bringing with it more clouds than sun, along with a good chance of some showers and thundershowers. At this point it doesn’t look like it will be much of a rain event, with overall amounts, for areas that do see some rain, of less than 10 mm. It looks like this system will move out by Saturday morning, giving us sunny to partly cloudy skies on Saturday and Sunday, with daytime highs continuing to be in the mid-20s and overnight lows in the mid-teens.

A ridge of high pressure is then forecast to build across central North America next week. This will bring mainly sunny skies along with slowly warming temperatures to our region over the week. Expect daytime highs to start off in the mid-20s on Monday and work their way into the upper 20s and low 30s by the second half of next week.

Usual temperature range for this period: Highs, 23 to 31 C; lows, 12 to 18 C.
