Did some comparison of the EURO's thinking for the next 3 months -previous AUG 1 outlooks & the current SEPT. 1 thinking. Very little change in Temps.- overall still warmer than average,-as for Precip.-look's like it shifted SE-ward more rains off the US East Coast #onwx #onstorm

Latest regional radar for the Great Lakes, scattered showers in NEONT and further south a small cluster of showers/storms, running almost parallel along the southern shore of L. Erie (US side) moving NE-ward. #onwx #onstorm

Fist wide spread blue's I've seen aloft so far this fall. Blue's=below 0C temps at 850mb (or ~5k/ft.) Black= near 0C. Most of this cooler air aloft stays well north of SONT & transits W to E ( & does not stick around too long fairly progressive pattern) #onwx #onstorm

Your daily "fix" of MLCAPE for SONT. Highest CAPE values in SWONT/over L. Erie. There is some indication that some lake breeze segments may form, if so, they may kick off a few showers/iso. storms north of Lakes Erie & Ontario. We'll see. #onwx #onstorm

Latest hourly run of the HRRR- Radar 4cast- till Midnight. The bulk of the scat. showers and storms stay just south of the lower lakes with risk S. sections of EONT. For NONT scat. showers/risk storms along that cold front moving into Quebec. #onwx #onstorm

A low pressure system moving out of South Dakota is set to once again bring active weather to northwestern Ontario late Friday and into Saturday. #ONstorm #ONwx

Active weather is set to move across the international border, bringing the risk of severe storms to parts of northwestern Ontario before the weekend. #ONstorm #ONwx

There were accounts/people who complained that the red warning was an overkill scare tactic, and Toronto mayor Oliva Chow should apologise because they didn't get hit directly. Toronto Sun columnist Warren Kinsella (aka idiot) being one of them.

The NTP has confirmed another tornado in southwestern ON with the storms on Sep 2, this time just north of Wellesley. The tornado has been rated EF1 based on the results of a damage survey that included parts of a barn roof being removed and thrown.

An upper trough will move across the Great Lakes throughout the day on Wednesday, elevating the risk of thunderstorms in southern Ontario. Some of them could turn severe, with heavy rain, gusty winds and localized flooding as main threats. #ONstorm #ONwx www.theweathernetwork.com/en/news/weat...
