We're not sure what it is about weekends around here, but another low-pressure system is coming into Portage again... this coming weekend.
Environment Canada Meteorologist Sara Hoffman says it's technically not a Colorado low, but Wyoming wants to get in the fame and have us call it a Wyoming low.
"We're seeing things continue to sort of stabilize after we had that low-pressure system swing through over the weekend, bringing a lot of rain, snow, and strong winds," says Hoffman. "We are still looking at well-below normal temperatures. Normal for this time of year is a daytime high of 14 degrees Celsius. It looks like we will never reach the normal for this time of year at all this week, even into this weekend."
Hoffman says, even though we have two days that seem kind of dry -- Tuesday, Wednesday -- we have another approaching low-pressure system from the United States which will start to make it in our area by late this week into the weekend.
"So, we are looking at more rain," adds Hoffman. "I think folks have taken to calling every single low-pressure system that sort of swings up from the United States into Manitoba, a Colorado low," adds Hoffman. "This one actually originates in Wyoming. It's definitely going to be a system to watch, to listen to the warnings, and the advice of emergency managers in your area because of the back-to-back systems. Even though this system could be sort of not impactful on its own, or not looking at too high of precipitation amounts with this, because it comes on the heels of back-to-back impactful systems, it could really be a very serious system."
Hoffman notes it's going to be important to stay tuned to the weather forecast, but also the news and what City Hall emergency preparedness teams are saying in our area.
"At this point in time, it looks pretty warm," continues Hoffman. "So, it looks to be mainly rain, at least at the start, and then as the cold front kind of swings in behind it, it looks like it could change to snow for early next week. So, it's snow over a week from now, but I want to add a heavy caveat there. Springtime forecasting is very difficult and that's what it looks like right now, but that forecast could change. It does make a lot of conceptual sense that the precipitation would start as rain and then eventually change to snow."
She adds precipitation 24-hour amounts from Friday evening to Saturday evening, they're expecting 10 to 25 millimetres.
"And then from Saturday evening to Sunday evening, we're looking at 10 to 20 millimetres," says Hoffman. "I would say probably, for an event total, something like 20 to 50 millimetres of rain over the course of 48 hours. There is some embedded convection in thunderstorms which made the amounts locally higher. And I'm not quite sure that risk is at the same level as this event, but it is possible that there could be very localized pockets with heavier amounts. On the whole, we're looking at probably about 20 to 50 millimetres."
Hoffman acknowledges that's all the way into next week, so things could change, especially if the track below changes, or anything similar occurs.
