Strong northwesterly winds threaten damage, outages across southern Ontario

The month of April will come to a close feeling much more like the middle of March, as cool temperatures, the threat for snow flurries and powerful northwesterly winds whip into the region for Friday. Widespread special weather statements are in effect for southern Ontario, warning of potential damage to tree branches and isolated power outages. While the winds will ease heading into the weekend, temperatures will struggle to stay warm. The region will remain a battleground between the warm and cool air into next week as well, with no consistent signs of any warmth right through the first week of May. More on the cool and blustery end to April and how the start of May is shaping up, below.

FRIDAY: MARCH-LIKE WEATHER FOR THE FINAL DAY OF APRIL, STRONG NORTHWEST WINDS

After a mostly dreary and wet day on Thursday, the last of the rain fell through the evening hours across the south, though will continue to linger for eastern sections of the province through much of the day on Friday.

Temperature-wise, Friday will be feeling more like a mid-March day, as daytime highs struggle to even reach double digit values and powerful northwest winds with gusts of 70-80+km/h threaten much of the region.

A special weather statement is in effect for those winds, covering the entire GTA and southwest of the province, with gusts ramping up Friday morning and lasting throughout the day.

"These strong winds will toss loose objects and may cause some tree branches to break," warns Environment Canada in the statement. "Isolated power outages are also possible."

With these cool temperatures in place, there's even a chance of a few centimetres of snow for parts of cottage country, with flurries and graupel possibly reaching all the way to the GTA late in the day.

WEEKEND OUTLOOK: HOVERING NEAR SEASONAL, THREAT FOR PASSING SHOWERS

Temperatures will continue to be on the cool side of seasonal on Saturday, with rain showers developing later in the day.

There's a wide range in computer model forecast temperatures for Sunday, depending on the exact position of the warm front as it advances into southern Ontario through early Sunday.

"Parts of southern Ontario wills see some sunshine and temperatures climbing into the 20s. However, areas near and north of the front will be much cooler with a threat for showers," says Dr. Doug Gillham, a meteorologist at The Weather Network.

LOOK AHEAD: LACK OF ANY CONSISTENT WARMTH INTO MOTHER'S DAY WEEKEND

The next soggy system tracks into the Great Lakes Sunday night, pushing across southern Ontario and southern Quebec on Monday. Another follows closely behind Tuesday night and into Wednesday, with more rain showers possible for southern areas.

Next week will also feature a similar pattern in that the region remains a battleground between the very warm air south of the border and cooler weather to the north. While southern areas could see a couple of days of warm temperatures, any warmth will be short-lived as cooler conditions return for the second half of the weekend and into Mother's Day weekend.

"We'll see a chilly pattern for the end of the week and into the weekend with a threat for showers and even some graupel, and we will need to closely monitor the risk for a freeze if we get clear and calm conditions one of the nights," Gillham adds. "That chilly pattern is expected to continue through May 10."

That's thanks in part to a blocking high over Greenland, which is setting back up again and forcing colder air southwards.
