Slight risk of severe thunderstorms Sunday in Alberta

A slight risk of severe thunderstorms Sunday July 31. MLCAPE is only 750-1250 but with 30kt mid level and 60kt upper level shear isolated severe thunderstorms are likely with large hail and high winds. Any supercells will be the LP variety due to dews barely getting into the mid teens. The dry August air appears to be making an early appearance, as is the August heat. August is LP month for sure, and hopefully no more soupy green hail bombs this year.

On another note the setup last Monday became nocturnal with storms firing up all night along the QE2 between Olds and Leduc. Since then another 2 days saw thunderstorms once again including Non-severe storms along #13 on July 28 and severe cells around Calgary on the 29th that promoted tornado warnings. Even with CAPE values as low as 500j/kg the Shear was enough to keep the severe thunderstorms going

  1. In Edmonton I can see clouds at different levels moving in 3 different directions. north, south and west so shear is there for sure. Whats the risk for Supercell storms rolling through Edmonton? just something feels weird today the neighborhood dogs wont shut up, and another neighbors parrot is making strange and very odd noises .
