Active Few Days on Tap for the Prairies starting Sunday


Well it looks like a big bad upper low will be showing its face over the Western Prairies starting on Sunday.

This setup should yield some strong-severe thunderstorms along the foothills on Sunday which will pave the way for a better setup on Monday over West-Central Saskatchewan as the Upper Low edges slightly Eastward. A moist & healthy H85 jet gets going early Monday as the mid-level flow crosses over from the WSW at a decent clip. This should allow for great speed/directional shear with height. Now tie that in with high temps/dews at the surface and some cold air aloft and we my friends have an atmospheric profile with steep lapse rates conducive to supercells with large hail and possible tornadoes when you factor in the forecast shear profiles.

The tornado threaticus looks to be maximized along a Battleford - Saskatoon - Outlook Line along a warm front/surface trough that looks to be situated in that area around 4pm on Monday.

I've already heard that a certain someone may be making the drive from Winnipeg if this setup pans out the way the 00z NAM run suggests. Tuesday could be interesting too with the focus shifting slightly eastward towards the Regina - Yorkton - Estevan area.

Either way this setup bears watching since we might be in for 3 severe weather days...with the latter two days having heightened chances for tornadoes.

Ahh, this second night shift is killing me...I need some sleep!

Over and Out!!!
