A slow-moving low-pressure system has brought even more rain to an already soggy Pembina Valley. Precipitation began falling across the region early Sunday morning, and is expected to continue to today across Southern Manitoba.

Our PembinaValleyOnline.com Rainwatchers, as well as the Manitoba Ag Weather Program and Environment Canada, have reported the following totals so far. These figures are for Sunday through Monday morning:

Morris area (Rainwatcher reading) – 2.2 inches
Altona – 1.6 inches and a report of 2.4 inches
Morris (MB Ag reading), Sprague - 1.3 inches
Gretna, Winkler – 1.2 inches
Manitou, North of Horndean – 1 inch
Schanzenfeld/Morden/Pilot Mound,/Woodmore - 9/10ths
Dominion City, Two miles South of Morden - 8/10ths
Carman – 6/10ths
Elm Creek – 1/2 inch

“You may be wondering why the Altona area, and parts of the Red River Valley, seem to be an outlier compared to most of the other locations,” noted CMOS Accredited Weathercaster Chris Sumner Monday morning. “There were embedded thunderstorms within the overall system, particularly late Sunday afternoon into the evening hours, and the places which saw those storms go overhead received significantly more rainfall than neighbouring areas.”

More rain is expected Monday, possibly a further additional 5 to 10mm, before this system pulls out of the region. Temperatures will start the week well below average for this time of year, ranging in the 6 to 8 degree range Monday through Wednesday. Daytime highs will start to edge back toward normal Thursday. 15 to 16 degrees is the average day-time high for the first week of October.

“Unfortunately it looks like the rainy and wet pattern will continue as we get into October,” added Sumner. “The forecast models are showing a chance of more rain on Wednesday, and a second system possibly impacting the region next weekend (October 5th/6th). Right now the long range forecast suggests we may see a return to a sunnier and drier pattern the week of October 7th.”
