Moisture is at its peak right now. Surface dews are progged to be in the low 20s. Up to 850, even, it looks to be moist--dews over 15°C.


That will lead to slightly-capped MLCAPEs in excess of 1000 and even 1500 J/kg. Not too shabby, if you ask me.


With 500 mb flow increasing with the approach of a vigorous trough, deep-layer shear will be good--great, if you add in the 850 mb winds crossing rather nicely (shown above).

Surface lifting will, I suppose, be a question but if a front or outflow boundary sharpens up, the game will be on.
If I were chasing, I would aim for Weyburn, SK, for an initial target and go from there.
