It looks like we will have a predominately west to northwesterly flow across agricultural Manitoba during this forecast period. The upper level pattern has a large area of low pressure over northeastern Canada with a ridge of high pressure over the far western states. The flow in the upper atmosphere is riding over the western ridge and then diving southeast and wrapping around the eastern low. Depending on the strength and position of these two features we will either see a westerly flow or a northwesterly flow.

Overall, the weather during this forecast period should be fairly pleasant. It is not very likely that we will see any big-time heat, but highs on most days should be in the low to mid-20s. The one weather system we have to watch out for is an upper level low that is expected to track through our region on Thursday and Friday. The exact track of this low is a little uncertain but areas near and north of the low could see some significant rainfall.

Over the weekend we should see weak high pressure build in bringing partly cloudy to mainly sunny skies along with nice temperatures. The models are then showing another area of low pressure developing to our west and moving eastwards during the first half of next week. While confidence in this system is not that high, this could bring showers and thunderstorms to our region late on Monday and into Tuesday.

Looking beyond this period the models are showing high pressure moving in bringing with it warming temperatures and dry weather.

Usual temperature range for this period: Highs: 22 to 31C Lows: 10 to 18C.
