Additional rainfall received Wednesday morning has only inflated already significant totals received across the region this week.
"The brief, but intense, downpour brought another significant dump in places that already had anywhere between 100 and 150mm earlier this week," explained CMOS Accredited Weathercaster Chris Sumner. "The Winkler and Morden area, south into the R.M. of Stanley, based on our Rainwatcher reports, again appears to have received the highest totals."

Sumner noted the line of showers and thunderstorms pushed northward out of North Dakota while we were getting ready for work and school Wednesday morning.
"In most places, the rain lasted less than an hour, but the rainfall rate was very high, and that's why we're seeing the totals we are considering how brief the precipitation lasted in some spots," he said. "Thankfully, conditions did not come together Wednesday night for another round that had initially been suggested in the forecast model runs. With that said, some widely scattered thunderstorms did pop up over the course of the evening, and a Severe Thunderstorm Watch was issued for the Pembina and Red River Valleys, but the vast majority of the area did not see additional accumulations."
The following totals are for Wednesday, September 18th, and are courtesy PembinaValleyOnline Rainwatchers and the Manitoba Ag Weather Network:

25mm = 1 inch
Meanwhile, there has been some improvement in the forecast since yesterday, with a decrease in the likelihood of additional significant rainfall the next few days.
"As the upper level low that's been impacting the area for the last day, or so, continues to push northeastward, it could trigger some showers and thunderstorms today, primarily this afternoon and tonight," said Sumner. "Beyond that, we're now seeing a drying period starting Friday, as we get into a westerly flow tomorrow. Saturday is also looking relatively dry, and so is Sunday, as surface high pressure moves through the province over the weekend. Seasonal temperatures are expected through the weekend, and early indications are we could see a slight warm up into the low 20s by mid next week."
We're expecting sunshine to start Thursday, with cloud cover rolling in later on, alongside gusty southwesterly winds and highs around 23, which is about five degrees above average for this time of year. Average daytime highs are 18 degrees, and 6 degrees overnight.
