Forecast – for Jun. 23, 2011

Well, it felt a little more summerlike this past week and some areas were able to dry out, but other areas got hammered once again with heavy rains coming in the form of thunderstorms. In what seems to be a pattern this spring, we are once again starting this forecast period with a strong and slow-moving area of low pressure affecting at least part of our forecast region.

Hopefully this system will stay to our south during the first half of the week and it will kick out quicker than anticipated by the weather models. If not, it could impact the forecast for the second half of the week. It now looks like this storm system will push to the east by late Wednesday or early Thursday. Behind this system high pressure will try to establish itself, bringing sunny to partly cloudy skies along with temperatures in the low to mid-20s for highs.

Over the weekend, weak high pressure should continue to dominate, bringing sunny skies and continued nice warm temperatures. A trough of low pressure is then forecast to push through southern and central Manitoba some time between Sunday and late Monday, bringing with it clouds along with a good chance of some showers and thundershowers. For the middle part of next week, a weak high pressure system will try to build back in, and should give us more sun than clouds along with temperatures in the mid-20s for highs.

Looking further ahead the models are showing a strong area of low pressure developing to our northwest. The models then bring this system across well to our north. Ahead of this system we will see a strong southerly flow develop which could push temperatures into the 30s for the first time this year.

Usual temperature range for this period: Highs:20 to 29 C.Lows:8 to 16 C.
