The results of relatively light Monday evening showers greeted Pembina Valley Rainwatchers as they checked their gauges Tuesday morning.
"A low pressure system moving across southern Manitoba, near the international border, kicked off the latest round of precipitation in the afternoon in the southwest, and in the early to mid evening in the Red River Valley and southeastern Manitoba," said CMOS Accredited Weathercaster Chris Sumner. "We weren't expecting a lot from this system, and the totals this morning back that up. There wasn't a lot of moisture within this particular airmass, and that's why we saw the lower totals we did."

According to Sumner, cloud cover on the backside of the low will lead to a mainly cloudy Tuesday and gusty winds up to 50-60 km/h, first from the southwest and then the northwest as the low passes through the region.
"Wednesday looks like it could be the warmest day of the Spring and Summer, so far, as upper level ridging allows a very warm airmass to briefly settle into the area," he explained. "Highs pushing the upper 20s are likely. I'm not sure if we'll reach that magical 30 mark, but depending on how much sunshine we see tomorrow, there could be a location or two that gets close."
Sumner is watching the risk for severe thunderstorms Wednesday afternoon and early evening, because all the ingredients will be in place with warm, moist air over the region and another low pressure system moving in from the west possibly being the trigger to kick-start that activity.
"Behind that system, we're expecting a couple of quiet days, as surface high pressure builds in over the area," he added. "Highs Thursday will be cooler than Wednesday as a northwesterly flow develops behind the Wednesday system, but temperatures are expected to creep back up again heading into the weekend as a warmer airmass that's been over B.C. the last several days finally is able to make its way to the eastern Prairies."
Sumner noted there are multiple chances for showers and thunderstorms over the weekend, but it's still too early to say with much confidence what timing and amounts may look like.
