Rain will continue Saturday as the third Colorado low in about three weeks impacts the region. A Rainfall Warning remains in effect for most of Southern Manitoba from as far west as the Killarney and Brandon areas, all the way to the Ontario border. According to Environment Canada, an additional 10 to 25 mm is expected over the next 24 hours.

"Other than a few isolated heavier bands of rain, precipitation over the Pembina and Red River Valley, to this point, has fallen at a relatively moderate rate," explained CMOS Accredited Weathercaster Chris Sumner Saturday morning. "That has certainly helped allow whatever drainage capacity is still available throughout the area to take on some of that additional run-off. With that said, as run-off rolls off the escarpment, and heads eastward over the next day or two, that's when we will get a true sense of just how much of this rain event will end up running off. The ground, throughout the area, is completely saturated, and there really isn't any capacity for it to absorb any additional moisture. That means a lot of what we receive from this latest system will end up in drains and ditches, and ultimately streams and rivers like the Pembina and Red River."

The following are some regional rainfall rates through 5 a.m. Saturday, April 30th, keeping in mind additional rainfall is expected throughout the day. All totals are courtesy of the Manitoba Ag Weather Network and Environment Canada. All totals in millimeters:

Sprague Lake - 26.6mm
Snowflake - 26.2
Carman - 25 (1 inch)
Manitou - 22.7
Brunkild - 20.7
Altona - 20mm (8/10ths)
Somerset - 19
Emerson - 16.9
Winnipeg - (airport) - 16.7
Steinbach - 16.6
Elm Creek - 15.3
Morris - 15.2 (around 6/10ths)
Dominion City - 14.1

25mm = 1 inch

"To this point, the highest precipitation totals have been east of the Red River, with a number of locations already well over 25mm, or an inch, of rainfall," noted Sumner. "Those totals will continue to grow today, and put pressure on already swelled waterways in that region like the Rat and Roseau Rivers."

In Friday's Flood Bulletin, the province indicated there is a risk of moderate flooding on the Roseau and Rat rivers, as well as in the Whiteshell lakes area. A flood watch has been issued for the Roseau River.

"The rain will taper off early Sunday morning as the Colorado low moves out of our region," said Sumner. "On the backside of the system, we can expect the typical gusty northerly winds to develop, potentially up to 60 km/h in the Red River Valley. There is a chance we could see some shower or flurry activity Sunday afternoon, but we're not expecting accumulating amounts."

Sumner noted the warm and dry weather we are all looking for will arrive next week, as a significant pattern shift occurs.

"We're expecting high pressure to build in Monday and Tuesday, bringing a return to sunny and seasonal conditions," he said. "After several weeks of well below average temperatures, we'll finally get back to not only average, but more than likely above average as we get later into next week, as a southerly flow brings much warmer air into the region. Right now, the long-range models are showing daytime highs between 17 and potentially 23 from Wednesday through next weekend."

Averages for this time of year are 17 for a daytime high and +3 overnight.
