Soggy start to the week, below seasonal temperatures in Ontario

Sunday, May 2nd 2021, 10:09 pm - Temperatures will be below seasonal by the end of the week in Ontario and some areas could see showers and possibly graupel.

The week will begin on an unsettled note across Ontario due to several systems that will impact the region. The sunshine will try to make an appearance mid-week, but most of the province will experience overcast skies over the coming days. Temperatures will be below seasonal and forecasters see no signs of sustained warmth for the first half of May in southern Ontario. Details and timing, below.

MONDAY: WIDESPREAD RAIN WITH NEXT SYSTEM, TEMPERATURES DIP

A boundary that is sitting over the province will slightly shift to the north on Monday, which will allow a system to slowly track along it in southern Ontario. This system will bring widespread showers in the afternoon hours, which will re-develop into Tuesday afternoon.

LOOK AHEAD: POTENTIAL FOR MORE RAIN, LACK OF ANY CONSISTENT WARMTH FOR FIRST HALF OF MAY

Another system is expected to track south of the Great Lakes on Wednesday, with the potential for more rain. Some models track this system too far to the south to impact the region. The greatest threat of showers is likely early Wednesday.

A rather chilly pattern is anticipated for the end of the week and on weekend with a threat for isolated showers, and possibly some graupel. Forecasters will be keeping an eye on the potential for a hard freeze if there are clear and calm conditions during any of the nights.

The chilly pattern is expected to continue through at least May 10, and possibly through the second week of May. While March and early April brought an abundance of May-like temperatures, the first half of May will feel more like early April.

Be sure to check back for updates on the spring temperature rollercoaster across southern Ontario as we head into May.
