Southerly winds will pick up tomorrow to between 20 and 30 km/h and remain strong throughout Monday night and Tuesday ahead of a strong low pressure system in the northern Prairies. This will usher in much warmer weather. Highs will be in the 21 to 22°C range on Monday and 25 to 27°C range on Tuesday with lots of sunshine.
Things get interesting on Wednesday as a Montana Low moves into southern Manitoba. Weather models have been hinting at this system since last week. A strong southerly flow in the low levels of the atmosphere will usher in plentiful moisture so it will feel a bit humid. Thunderstorms are likely with the associated fronts with this system Wednesday night. Exact location of these storms is difficult to predict this far out but all of southern Manitoba will have the opportunity for these storms.
The following is a surface temperature map with approximate front locations for 4 pm Wednesday... from the NAM weather model.
|Keep in mind this a weather model forecast... therefore things wont actually look exactly like this in reality|
Much cooler weather will likely make a brief return behind the system.
