The latter days of April have featured some decidedly unspring-like weather, and the month is going out on a similar note, with cooler temperatures and strong winds, and even the chance of a few flurries for areas north of the GTA. The region will remain a battleground between the warm and cool air into next week, with no consistent signs of any warmth right through the first week of May. More on this spring temperature flop, below.
THURSDAY: WIDE TEMPERATURE DIVIDE CLOSES, COOL AND DRIZZLY DAY
The thunderstorm threat that covered parts of southern Ontario Wednesday has now passed, with temperatures taking a noticeable dive from the 20-degree highs in the southwest, and cooler conditions continuing through the Greater Toronto Area as we close out the month.
As well, a system tracking south of the border will bring in another bout of rain showers throughout the day, making for a mostly wet and gloomy Thursday.
A widespread 10-20 mm is expected, with heavier amounts for eastern sections of the province by the time it tapers off through Friday.
INTO FRIDAY: MARCH-LIKE WEATHER FOR THE FINAL DAY OF APRIL, STRONG NORTHWEST WINDS
After some overnight showers, much of southern Ontario will be dry by the morning hours, though some showers may linger somewhat in eastern Ontario. In all, the province will be tallying some 10-20 mm from Thursday's round of showers, though once again, eastern Ontario will be a bit soggier, with some areas seeing the 30-40 mm in their rain gauges.
Temperature-wise, Friday will be in the midst of a cooling trend, as well as having to deal with some strong northwest winds gusting between 50-75+ km/h.
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 through the day.
With these cool temperatures, 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," says Dr. Doug Gillham, a meteorologist at The Weather Network. "It'll be March-like weather for the final day of April on Friday."
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.
A tricky forecast for Sunday, with a warm front anticipated to push into the region, but with a lot of uncertainty as to how far north the front can advance.
"Some sunshine and very warm temperatures are expected south of the front (low to mid 20s), but near seasonal with a round or two of showers along and north of the front," Gillham says.
LOOK AHEAD: LACK OF ANY CONSISTENT WARMTH INTO MOTHER'S DAY WEEKEND
Next week will feature a similar pattern as 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.
"There will be no consistent warmth through the first week of May, but we're watching signs of a warmer pattern starting the second week of May," Gillham adds.
That's thanks in part to a blocking high over Greenland, which is setting back up again and forcing colder air southwards.
