Severe Thunderstorms With Flash Flooding [Today's Outlook Map]

There are some big storms popping up all over eastern and central Saskatchewan including Manitoba this afternoon. With extreme heat to the west, and high CAPE values, these slow moving, high topped storms will produce a lot of local rain which could result in flash flooding. Storms are expected to persist late into the evening where a chance of tornadoes exists around sundown.

Weak Tornadic Storms Today, Bigger Ones Friday...

Tornado Warnings have been issued in southern Manitoba this afternoon with confirmation of at least one touchdown.

The storms today are are very slow moving, mostly rain event type with some possible spin ups of weak tornadoes. There will be no map today, keeping with the consistent model forecasts of scattered non-severe thunderstorms. If any damage occurs from these cells, it will be a possible tipped lawn chair and a lot of rain. Flash flooding should be the main concern today.

Friday on the other hand, looks to be quite active for stronger type supercell thunderstorms that can cause widespread damage. Here is a look at the difference between the NAM forecast model for 9pm this evening and 9pm Friday evening. This is the forecast "supercell composite":

Storms Moving Into Manitoba Today

After a very active day yesterday, systems are pushing east into Manitoba. Today's storms are not expected to be tornadic or have very organized supercellularities thus, the slight risk is only for gusty winds, small hail, intense lighting and heavy rains. After today, if anything severe, the rest of next week is forecast to have general to marginal thunder showers and nothing very severe until closer to Canada Day. July 1st to 3rd is looking like the next big system at the height of storm season on the Canadian Prairies. Plan accordingly and as always, be prepared and stay safe!

Storm Chasing Action via Mountain Bike!

Regina, Saskatchewan

June 19, 2015

5:50pm to 6:30pm



Began to see nice structure by the stadium construction site. At Dewdey and Lewvan Drive, I decided I had gone far enough as a rain and hail shaft began to appear! Initially, radar had indicated that it was moving slowly south east (15km/hr), making for an easy chase by bike. But suddenly, the line of cells began to wrap around and the south end rapidly flew across the city (after analysis at home, calculated it clocked up to 60km/hr and became tornado warned just 70km east of the city). Rode the storm home in 20 minutes via mountain bike! Some footage shot in action as i strapped the camera to my back and booked it towards safety! Now that's storm chasing! Pea size hail and a brief heavy downpour as I got home. Barely got wet.
