The first of two upper level lows to impact Southern Manitoba over the next few days produced a grey, damp and cooler than average Friday to kick off Canada Day long weekend.
"The rain began Thursday night, and as we expected, was off and on throughout Friday before finally tapering off late last night or early this morning in areas east of the Red River," said CMOS Accredited Weathercaster Chris Sumner. "With this first system out of the way, we can enjoy a couple days of sunnier and warmer conditions, before a second upper level low aims to bring much of Southern Manitoba a wet July 1st."

Sumner noted the best days of the weekend will be Saturday and Sunday, if outdoor plans are in your mix, those are the days to do them.
"Surface high pressure has been building into the region overnight, and that will clear out the lingering cloud cover form Friday's system, meaning lots of sunshine today and temperatures rebounding a few degrees, but still well below average for the end of June," he said. "Highs today will be around 18 to 20 degrees, with warmer temperatures Sunday between 21 and 23."
The average daytime high for the end of the month is 25, with the overnight low 12 degrees.
"The forecast models continue to indicate Canada Day Monday will be a wet one, with another upper level low coming in off the Pacific northwest, tapping into additional moisture from the southwesterly flow ahead of it, and then taking almost exactly the same track across the Prairies as the Friday system did," he explained. "That means we can pretty much bank on more rain July 1st. How much and whether it will be a steady rain throughout the day, or could there be some breaks periodically, that is still a little uncertain. With that said, at this point, preparing for wet weather Canada Day would be a good idea."
