Issued: Monday, June 28, 2010 Covering: June 30 –July 7

This forecast period starts off with fairly quiet nice summer weather, but it doesn’t look like we’ve rounded the corner just yet on the unsettled stormy weather we’ve been experiencing for the last couple of months.

While temperatures look as if they will remain fairly mild, we will see clouds and the chance of thunderstorms move back into our region by Thursday. An area of low pressure will slowly push across central North America later this week, bringing with it warm/hot temperatures and unsettled conditions. An indication that we are moving deeper into summer is that the weather models now show the main area of low pressure from this system to form much further north. This means southern and central regions of Manitoba will be under the influence of a trough of low pressure stretching south from the main low. This should help keep us milder and we should see more sunshine.

Unsettled conditions will last through the weekend as a cold front pushes through. The exact timing of this front is uncertain but temperatures behind the front will cool down, with highs only expected to be in the low 20s.

Next week the parade of lows will continue, with several lows forecast to move through, but, as it was over the weekend, they should all stay well to our north. This means we will see temperatures rise ahead of each low and then cool off as cold fronts push through once the low passes by. The cold front will not only drop temperatures back down to the lower end of the usual temperature range for this time of year, but will also trigger thunderstorms.

Usual temperature range for this period: Highs: 21 to 31 C. Lows: 9 to 18 C.
