The calendar has changed to June, but the cool weather will continue this week with no end in sight to the below normal weather pattern. Today will see sunshine giving way to scattered afternoon showers and thunderstorms as a cold front approaches from the west. This front will bring in cooler air for Tuesday with highs only around 14C. This will lead to a potential for frost early Wednesday morning under clear skies and light winds. Wednesday looks like the nicest day of the week with sunshine and temperatures near 20C. Then things turn ugly for Thursday and Friday. Gusty northwest winds Thursday will usher an unseasonably cold airmass over southern MB with temperatures struggling to remain in double digits. In fact, the airmass will be cold enough to produce snowflurries over higher elevations Thursday night. Frost is a distinct possibility early Friday and Saturday, although cloud and wind may protect us from a widespread killing freeze. Nevertheless, this weather will test the patience of even the heartiest Manitobans who, after enduring 6 consecutive months of below normal temperatures, are wondering if and when the warm weather will ever arrive this year.
