Supercells in September?

 Supercells in September? The GFS is showing our next chance of big storms could be the start of September as the last week of August will be hot and dry with no storms. #skstorm #MBStorm

Storm Season Ends With A BANG! #abstorm #skstorm #yxe

According to this morning's GFS the long term outlook is nothing but heat waves and zero rain for the eastern prairies.

Winds reached nearly 150km/hr in last nights big storm that ripped across the western prairies from Brooks to Saskatoon. 

 Potentially multiple tornadoes but so far no perfect video to confirm any of them. The lightning was the real show around Saskatoon. The #skstorm hashtag is full of videos on X.

Big Storms Today: What the models say..

There is a vast difference as usual between the hrrr and NAM Nest models once again. Here are some clips of the most potentially significant severe weather. Generally along the SK/MB border there will be high risk of strong tornadoes. Another dangerous storm is expected in western Saskatchewan. Large hail and damaging winds will be the main factors there. The NAM Nest actually pins a maximum wind of 68 knots or 126km/hr as you can see in the last image. Some really impressive images here, now we wait and see how it all pans out.

 

Upgraded: High Risk Today / Risk of Tornadoes SK/MB

ECCC has upgraded today's Thunderstorm Risk to High along the SK/MB border. Tornadoes, hail up to 6cm and wind gusts up to 110km/hr are the main risks in the orange zone. #skstorm #MBStorm

Note: The storms are expected to emerge from the Regina area around noon and we are charging all devices in case there is a thunderstorm show to film here.
