Thanksgiving Sunday rainfall reported by Rainwatchers
Very similar to a week ago, a moisture filled low pressure system pushing northeastward out of the United States has brought precipitation across much of Southern Manitoba. That from CMOS Accredited Weathercaster Chris Sumner. "The main difference, this time around, is the area of heaviest rainfall, on the northwest side of the low, remained in Saskatchewan and northeastern Manitoba as it moved through the region," he explained. "The Red River Valley, and west toward the Manitoba escarpment, saw significantly less precipitation than initially forecast due to an area of dry air being pulled into the system. That dry air meant less moisture fell on our region. With that said, as you got closer to the Red River, and then east of it, amounts increased closer to the forecast because the dry air was later to arrive, allowing that rainfall to happen."

"As the low moved northeastward, we experienced gusty southerly to southeasterly winds Saturday afternoon through much of Sunday," noted Sumner. "According to the Manitoba Ag Weather Network, peak gusts on Saturday included Somerset and Baldur at 69km/h, and Altona and Morris at 67km/h. It's likely we will see even stronger gusts Sunday night, and overnight into Thanksgiving Monday morning." He explained the difference in pressure between, known as the pressure gradient, between the low pressure system and surface high pressure pushing eastward from the western Prairies will lead to the potential for even windier conditions. "It's possible we could see gusts in the 80+ km/h range, just like we did last weekend," he said. "Because we are south and east of the low's centre, the winds will be from the south to southwest until a cold front arrives and passes through. Winds will then shift northeasterly on Monday. Bottom line, Sunday night thought Thanksgiving Monday night will be blustery."

"Slightly below seasonal highs are expected for Thanksgiving Monday and Tuesday when we head back to work and school," noted Sumner. Average daytime highs for this point in October are 12 degrees, with overnight lows of +1
