A long-track tornadic supercell developed once again today in the mountains of Alberta and tracked east across the adjacent plains this evening, possibly producing tornadoes near Drumheller, AB between 6:30 and 7:00 pm MDT. Here is the radar image as the storm was just east of Drumheller:
Meanwhile, in Saskatchewan, a strong cap has suppressed convection for the entire day, with EXTREME instability in place across the southeast part of the province east of the advancing cold front. Convective initiation is still a small possibility here, and any storms that do develop will quickly become severe. The 8:00 pm CDT RUC analysis for CAPE is shown below...note the large area of 5500+ J/kg!!! However, it appears that this instability will likely not be realized.

Storms may be finally trying to initiate in SK...intensifying storms are now moving towards Yorkton.

Are the models showing anything significant for the next few days for Southern Saskatchewan or Saskatchewan in general. Suppose to cool down for tomorrow and possibly Thursday with this cold front.
As for this evening, Southwest Sask looks quite weak for any storms period with Southeast possibly late evening or early morning hours for Wednesday.
looks like may be north of yorkton by my home town north east of yorkton.
Aaron...sorry I lost you there. Looks like your house is in for some strong storms that's for sure. Let me know if you hear of any interesting reports.
Kalin...It looks like things are going to quiet down for SK for the next several days..at least through the weekend. This front will really clean out the good moisture.
Hey everyone
wondering if Okotoks AB is in for anything in the next few days. It has been hotter than a...well you know and we have some mild thunder boomers in the distance.
Final report on the Wetaskiwin super cell.
Trees snapped roofs blown off exposed buildings, severe hail damage to crops and trees shredded.

Sorry for the long address
I just got off the phone with Aaron...he's chasing the cell to the northeast of Yorkton right now near Kamsack, SK...he's seen a wall cloud and even possible funnels from time to time with it, and is reporting very frequent lightning. Right now the cell has a severe thunderstorm warning with it...I'll keep everyone updated if he sees anything more!
Hey guys. Just out of curiosity....what do you think of the severe weather threat in Manitoba for tomorrow? Are you gonna post about it? Please let me know. Thanks.

The storms near yorkton are producing a lot of lightning. Heres a link to Saskatchewan lightning data:

(thank you google :P)
Hey Jonathan...tomorrow could be very interesting in southern Manitoba...very good instability, and flow is good 700 mb and above. The low-level shear is forecast to be lacking, but the models don't seem to handle low-levels very well up there. I'll be adding a post late tonight or tomorrow morning.
We need the rain here in Michigan...hopefully that front will head this way!
Cool. I asked because I started making my own risk map for tomorrow like an hour ago*(not done yet:P) and wanted to see opinions from anybody else. Please....if anyone else here has an opinion please tell me.
