The Storms Are Forming (Rare computer generated image grabs)

Here is a rare image of CAPEs (Convective Available Potential Energy) maxed out over northern Alberta this afternoon at 21:00z (3pm SST) reading of over 6000 j/kg (buoyancy). Pink is 6000, white areas inside the pink is off the charts, estimated at 8000 to 12000 j/kg. Current CAPEs can be seen at this link.

Another image grab, from NEXLAB, College of Dupage Meterorology shows the squall line forming over north western Saskatchewan, streaming into Alberta to feed the ongoing supercells in the Edmonton and surrounding areas.

Severe thunderstorm warnings are now active in 4 quadrants of extreme north west Saskatchewan (another rare occurrence, in fact I have never seen that) as well as 8 quadrants of central Alberta, including cities of Edmonton, Red Deer. Image credit Environment Canada.
