Might feel like the hottest day so far in S. Ontario with humidex values near 40 this afternoon. More scattered showers & isolated t-storms are possible later today around Lake Erie & Ontario into E. Ontario. Risk of isolated strong gusts and 20-40+ mm of rain. #onwx #onstorm

[Andy Costa @AndyBlizzard87]

Some scattered showers & thunderstorms are expected across S. Ontario today & tomorrow with a tropical air mass moving in. Small risk of localized heavy downpours and gusty winds. Over 50 mm of rainfall is possible from slow moving/training storms. #onwx #onstorm

[Andy Costa @AndyBlizzard87]

Got a nice soaking today with 16 mm of rainfall so far in NW Kingston. #onwx #onstorm

[Andy Costa @AndyBlizzard87]

@julienalla11333 Probably go south of Ottawa into Smiths Falls.

[Andy Costa @AndyBlizzard87]

Warm and windy this afternoon in NW Kingston with temp up to 26°C. Nice looking storm developing near Sharbot Lake. #onwx #onstorm

[Andy Costa @AndyBlizzard87]

@julienalla11333 There is still a small risk for isolated severe in E. Ontario this afternoon. Not sure about later next week, lots of moisture and instability, but too far out to predict severe.

[Andy Costa @AndyBlizzard87]

Lots of heavy rain moving into the northern part of C. Ontario this morning with a cluster of showers and embedded storms. Might have to watch this for re-intensification in E. Ontario later this afternoon. #onwx #onstorm

@audio_nut Looks like near Lake Erie and E. Ontario have the highest risk with a later cold front passage. Guidance does show a couple of strong storms around the GTA in the early afternoon, though.

[Andy Costa @AndyBlizzard87]

Some rain finally on the way to S. Ontario tonight & tomorrow with humid air ahead of a cold front. A few showers & scattered t-storms are possible with a trace to 10 mm for most, locally heavy in storms. Risk of isolated strong/severe storms tomorrow afternoon. #onwx #onstorm

[Andy Costa @AndyBlizzard87]

@julienalla11333 Maybe, it's a pretty low risk overall.

[Andy Costa @AndyBlizzard87]

Not too often that we get strong winds gusting up to 70-80 km/h from the north in E. Ontario. Just had a mature maple tree split in half in the backyard. #onwx #onstorm

Look's like ECCC expanded this overnight from deep SWONT thru to the north shoreline of L. Erie & L. Ontario.

@julienalla11333 @1Weathercanada Probably a squall line, slight risk of severe (10-15%.)

[Andy Costa @AndyBlizzard87]

@julienalla11333 Scattered storms with a slight risk of severe for most of S. Ontario. Damaging gusts are the main risk, but there's some ingredients for a brief isolated tornado.

[Andy Costa @AndyBlizzard87]

Brief taste of summer today & tomorrow across S. Ontario. Another line of storms is possible near Michigan & Lake Huron late afternoon & early evening with a risk of isolated severe. Might be a risk for an isolated tornado around Algonquin Park. #onwx #onstorm

[Andy Costa @AndyBlizzard87]

A couple of strong thunderstorms are moving in near Kincardine with isolated large hail possible. #onwx #onstorm
