\u201cSo hey, \u2026 having one washout day of three, I don\u2019t think is so bad,\u201d he said.<\/p>\n
He did admit that Sunday\u2019s \u201cwashout\u201d isn\u2019t ideal, but said at least it isn\u2019t windy.<\/p>\n
\u201c(It\u2019s) kind of a really a wet day and not a windy day. It\u2019s not a blowing around, but it\u2019s it really is kind of takes the fun out of being a long weekend in August, for sure,\u201d Phillips said.<\/p>\n

Dave Phillips, climatologist with Environment Canada Dave Phillips, a climatologist with Environment Canada, chats with CP24\u2019s Melissa Duggan on Aug. 2. <\/p>\n
Sunday\u2019s wet weather is part of a larger \u201cvery moist\u201d system, he explained.<\/p>\n
\u201cIt\u2019s very loaded with lots of moisture coming from centered on Indiana and then in the Iowa Valley. It\u2019s come through Lake Erie, and we see rainfall warnings for Niagara Peninsula could get up to 50 -plus millimeters of rain in the Toronto area and the GTA and through Kitchener and Durham (and) York region.,\u201d he said, noting that while a special weather statement has been issues for most of the GTHA, that could change if the system stalls and 50 mm of rain falls in an hour or less.<\/p>\n
Phillips said Aug. 2 is likely the day each year when the region will see 25 mm of rain or more, adding the good new is that by 4 or 5 p.m. there should be some relief as the moisture seen for most of the day should be \u201cless consistent.\u201d<\/p>\n
\u201cWe may see a couple of showers lingering tonight, but the drying out is going to begin, and tomorrow looks like an all dry day instead of an all wet day,\u201d he said, adding Tuesday also looks to be a good day.<\/p>\n
\u201cIt\u2019s going to be nice and more sun than cloud. And that\u2019s clearly going to be the situation come Tuesday.\u201d<\/p>\n
Persistent rain expected for much of the day: Environment Canada Environment Canada Senior climatologist David Phillips shares what to expect with parts of the GTA to be hit with heavy rainfall and thunderstorms. <\/p>\n
Overall, the summer of 2026 has been good weather-wise, the climatologist said, with upwards of 12 days of sun and heat in the region and normal amounts of precipitation.<\/p>\n
\u201cIf I was going to order the kind of summer for us here, I would order what we\u2019ve had,\u201d he smiled.<\/p>\n
\u201cSo far it\u2019s not been a washout kind of summer. It\u2019s been good, and you know we still have a month to go. We see August being maybe not kind as warm as July, but comfortable.\u201d<\/p>\n
