Last article’s general weather outlook was not too bad. The only part that was off a bit was the cool air that worked its way into our region late last week. The weather models originally had the cool air staying to our northeast, but the upper low that tracked through north-central Manitoba last week ended up being a little stronger than anticipated and this allowed the colder air to drop farther south.
For this forecast period it looks like we are finally done with cold air and a summer pattern is trying to take hold. The general flow across our region looks to become south to southwesterly, which means warmth, increasing humidity and the chance of rain. From June 3 to 5, weak high pressure is forecast to be in place across our region, bringing sunny to partly cloudy skies along with warm temperatures. Expect daytime highs to be in the mid- to upper 20s, with the odd 30 C reading not out of the question. Overnight lows will drop down to around 15 C.
Over the weekend it looks as though an area of low pressure will develop to our southwest and quickly move to the northeast by Sunday. This low will pull plenty of warm and humid air up into our region, with daytime highs pushing into the low 30s if there is enough sunshine. There is a good chance of showers and thundershowers with this low and significant precipitation is possible in some areas.
Behind this low there doesn’t look to be any push of colder air, so to start next week (June 8-10), we can expect sunny to partly cloudy skies with temperatures continuing to be near the top end of the usual temperature range for this time of year. Along with the warm temperatures and higher humidity levels will come the chance of the occasional thundershower, with the best chances for rain coming around mid-week as a weak low drifts through.
Usual temperature range for this period: Highs, 17 to 28 C; lows, 4 to 14 C.
