Two rounds of heavy rain and thunderstorms Canada Day wrapped up a long weekend book-ended by precipitation.

"Yet another moisture laden upper-level low, very similar to the one which brought rain on Friday, crossing the southern Prairies Monday bringing significant moisture to the region," explained CMOS Accredited Weathercaster Chris Sumner. "This system took almost the same track as the one Friday, so many of the regions which saw a good shot of rain then got another round, and in some cases considerably more. That low will slowly makes its way across Manitoba today toward northwestern Ontario."

Meanwhile, the latest round of heavy rainfall again prompted both Winkler and Morden late Monday night to ask residents to minimize water usage, with the sewer system in Morden overburdened by the high rate of rainfall.

In Winkler, the city was also reminding residents to ensure sump pumps were draining outside and away from their homes, and not into the sanitary system. As of Tuesday morning, the City was also asking residents to continue limiting water.

According to Sumner, the unsettled and wet pattern looks likely to continue this week with several chances for more rain and thunderstorms.

"As that upper level low tracks across the province today, it could kick off more showers," he said. "There remains ample moisture and instability in the atmosphere. If we see some sunshine break through the cloud cover today, that daytime heating would increase the instability over those areas, and could lead to non-severe thunderstorms developing Tuesday afternoon."

As for later in the week, Sumner noted daytime highs are expected to push back to seasonal, ranging between 25 and 27 degrees Wednesday through Saturday with muggy conditions continuing.

"We can expect to see daily thunderstorm chances, especially with more sunshine expected over the next couple of days," he said. "Multiple weak disturbances, combined with daytime heating, will provide the necessary mix for that very typical Summer pattern. As for our next chance of potentially general rainfall, the forecast models are showing a Pacific low crossing the U.S. plains, and into South Dakota which could lead to showers as far north as Southern Manitoba sometime between Friday night and Saturday."
