Last week we talked about arctic high pressure dominating the weather and it looks like the same thing will happen during this forecast period, at least during the first half.
It is currently looking like a strong area of arctic high pressure will build southwards over Western Canada during this week. This region of high pressure will squeeze the western low pushing it southwards. There is still a little uncertainty as to whether any of the energy from the western low will make it into southern areas of Manitoba during the first half of this week.

Thunderstorms and straight-line winds
Straight-line winds in thunderstorms can cause as much damage as a tornado and are next on our weather school list exploring how and why severe summer weather forms.
By Thursday, arctic high pressure will be in place and we will see temperatures running near the low end of the usual temperature range for that time of the year. This cold weather will last at least through to Saturday before the high pushes off the east and we start to see our temperatures moderate.
The models are showing an area of low pressure pushing through southern and central Manitoba on Sunday but confidence in this system is fairly low. It looks like we will be between systems during the first half of next week. Arctic high pressure will be to our north with weak areas of low pressure to our south. Temperatures should be fairly nice over southern areas with highs in the -5C to -10C range.
Looking beyond this period the weather models are trying to develop a stormier pattern but these models have been hinting at this type of pattern for over a month now and so far we have stayed pretty quiet.
Usual temperature range for this period: Highs: -14 to 0C Lows: -27 to -10C
