Showers/thunderstorms possible Friday into Friday night.. improving weather for holiday weekend..
High pressure over southern Manitoba today will give way to an increasing southeast flow ahead of a large scale storm system that will be developing over the western US plains/Rockies over the next couple of days. This system will draw increasingly more humid air from the southern US Plains by the end of the week, along with warmer air. This will lead to an increased chance of showers and thunderstorms over southern MB Friday, first ahead of the warm front in advance of the system, then along the cold front later Friday into Friday night. There is the potential for locally strong thunderstorms by Friday night, however that will depend largely on how much humidity can be drawn up with this system, and how much cloud will be around with the warm front. Cloudy and unsettled weather Saturday is expected to clear out by Sunday along with cooler temperatures, before a generally pleasant end to the holiday weekend with sunny skies and near normal temperatures Monday.
