The average high tempreautre at this time of year is 22 degrees, and that is the best we can expect over the next week or so. Cool weather persists. The upper level low that has been parked over western Canada remains, centred over BC and Alberta. It will give warning level rainfall to northwestern Alberta. Here in southern Alberta, on the south side of the low, we are dry. Friday will even be a sunnier day, as the low moves north and weakens. More sun will come ou on the weekend, but in the wake of the departing upper low, the air aloft will be cool, and that means an unstable atmosphere. Bottom line...we return to the familiar summer pattern of sunny mornings and afternoon thundershowers, starting on the weekend, and going into next week.
