Calgary Storm Update - June 29th, 2014

Low pressure zone comes near Edmonton down into active Doppler regions, goes south (near Montana / S.Dakota) then north again, then straight east into Manitoba...

This counter clockwise rotating system is what brought all that rain / moisture and heavy clouds, sweeping south west into Calgary from the north yesterday

What is interesting is how this moisture convergence, which can also be seen on surface analysis maps, is well-connected all the way down to Texas -- precisely where most of the petroleum refineries and massive power plants are located, emitting enormous amounts of smokestacks and aerosols!

The sky photograph below is facing south, just west of Calgary, showing the sweeping front coming in from the north.
