In just a short 6 months, this same pattern would be a full Hwy 21 closure from Goderich to Port Elgin with people stuck in snowbanks by Mitchell on 23. ❄️🫠

@cupofcarliejo @cupofcarliejo happy birthday 🎂🎉

[WxOntario @WxOntario1]

Sneak peak of fall is on the way to parts of Southern #Ontario tomorrow!

As mentioned yesterday, bands of Lake Effect showers/ rain are expected to develop overnight across areas east of Lake #Huron

It will also be a chilly day with temps struggling reach the upper teens (average highs this time of year are around +27C)

Similar to Monday AM, morning temps will likely be in the upper single digits across parts of SW and Central Ont and towards Cottage Country

Looking at the long range data, not seeing any multi day heat events until at least the second week of August

Update on tomorrows Severe Storm potential 👇

Models continue to show several rounds of storms tomorrow across Southern #Ontario

The atmosphere looks to recover after the eaely morning storms leading to significant CAPE (fuel) for the afternoon across SW/ Central Ont and the #GTA

At this point, the severe risk is looking isolated rather than widespread

The #Kincardine to #Cornwall and south has the best chance at seeing severe storms

Main risks: torrential rain (20-40+mm), strong wind gusts (90+km/hr) and large hail (2+cm). A brief tornado cannot be rulled out

Will have another update in the morning

#OnWX #ONStorm

Line of storms is expected to track through east of Lake #Huron between 3am and 6am

Overall, a cooler and drier than normal week

Temps will range from near 20C to the mid 20s Monday to Friday (temps may struggle to reach 20C Wednesday), things may warm up for the weekend with temps in the upper 20s

Tuesday is the only day that offers widespread rain chances, mostly dry the rest of the week

#OnWX #ONStorm

[WxOntario @WxOntario1]

Update on the severe storm potential for tomorrow 👇

Models continue to show a line of storms moving through the region tomorrow afternoon ahead of a cold front

We'll have to watch the showers/ storms during the morning that may hinder storm development as well as any lingering wildfire smoke

Greatest risk of severe storms looks to be from #Kincardine towards #Cornwall and south

Main risks- damaging winds, large hail, torrential rain. Slight risk of an isolated tornado

Will update layer this evening

This is near Armstrong, Ontario.

When will the Canadian National Railway Company make a statement about this incident?

Smokey sunrise this morning across #Huron County

Hazy skies and a string smell of smoke

Has the smoke made it to you yet?

#OnWX #ONStorm

[WxOntario @WxOntario1]

The latest HRRR model continues to show a massive plume of wildfire smoke making its way into Southern #Ontario tomorrow

Some areas could be in the thick of it for over 48hrs

Expecting to see similar if not worse conditions compared to 2023

Sweltering afternoon with temps in the mid 30s, upper 30s across the #GTA and #Toronto. Humidex values in the mid/ upper 40s

Our multi day heat event has begun across Southern #Ontario! 🔥

Widespread temps in the 30s across most of Southern Ont this afternoon

As mentioned last week, Tuesday (tomorrow) continues to be the hottest day of the week

Temps in the mid 30s expected across most of the region of the region with temps nearing 40C (without the humidex) possible across #Toronto and the #GTA 🥵

Heat event continues into Wednesday, possibly into Thursday but with temps in the low 30s

#OnWX #ONStorm

[WxOntario @WxOntario1]

Lake Breeze Boundaries are setting up across parts of Southern #Ontario

Circled areas have the best chance at seeing isolated showers/ storms later this afternoon/ evening

#OnWX #ONStorm

[WxOntario @WxOntario1]

Another dry stretch of weather is on the way to Southern #Ontario

As the heat dome/ ridge out west shifts eastward, it will block any chances at rain/ storms across the region

The next 7 days look very dry with little to no rainfall expected for most

#OnWX #ONStorm #OntAg

[WxOntario @WxOntario1]

After a bit of a break from the heat, looks like another multi day heat event may be on the way to Southern #Ontario next week

The ridge/ heat dome out west appears to flex/ shift eastward, pushing heat into the region

Doesn't look anywhere near as hot as last week and not as long duration

Several days (Monday to Wednesday) of temps in the low/ mid 30s, humidex values upper 30s/ near 40

Big cool down possible by the weekend!

#OnWX #ONStorm

[WxOntario @WxOntario1]

Very warm start to the day across Southern #Ontario

Temps range from the upper teens to low 20s

Temps peak in the upper 20s/ near 30C before the line of showers/ storms move through

Still looks like a broken line of storms will track through the region early afternoon

Could see scattered storms develop out ahead of the line- those could become severe
