After a week of warm spring temperatures, flurries are in the forecast this weekend in Waterloo region, Guelph and area.

But don’t worry, it’s perfectly normal.

“It’s quite normal actually to see snow this late in April,” Monica Vaswani, a warning preparedness meteorologist with Environment and Climate Change Canada told CBC News.

“It’s still the sort of early spring season at this point. We’re still getting winter trying to make its exit while the warmer spring and summer temperatures are starting to move in,” she added.

“There’s always going to be this battle of the warm and the colder temperatures.”

Vaswani says a weather system formed over northwestern Ontario on Thursday that is developing a large low pressure system that includes freezing rain and snow.

That system is set to track through the province and into southern Ontario on Saturday.

Warning: It’s going to get cold

Waterloo region and area has seen temperatures in the high teens and even 20s with humidity this week, but Saturday is going to see a drastic drop from 17 C during the day to 1 C overnight.

Sunday the forecast says the high will be 8 C but there’s a chance of rain showers or flurries and the overnight low will drop to –5 C (yes that’s a minus sign).

Monday will see a high of 3 C and that chance of flurries remains with overnight temperatures dipping below freezing into Tuesday morning.

This rollercoaster of temperatures means people need to pay close attention to conditions on roads, sidewalks and trails, Vaswani says. That’s because ice could form when the temperature dips below 0 C.

“You definitely want to monitor though, and take a look at the sidewalks before you head out,” she said.

Flurries are possible during the morning commute on Monday with cold northwesterly winds expected until later in the day.

The other thing to watch for are thunderstorms over the next few days, Vaswani said, which may move through the region alongside the cold front.

“Even though we may not have any warnings out due to the thunderstorms, there’s still always a risk involved with lightning. So if you do see any lightning or hear any thunder, make sure to head indoors for your own safety,” she said.

Flood watches and warnings in effect

The additional rain and snow may lead to even more soggy areas around the region.

On Wednesday, after heavy rains during the week, the Grand River Conservation Authority issued a flood warning for West Montrose and Kitchener and a flood watch for New Hamburg and Ayr.

“River levels are increasing as a result of this event and may further increase due to additional rainfall,” the authority said.

The authority also issued a water safety message to remind people to stay well back from streams, rivers and other bodies of water because banks may be slippery and the water is still very cold.
