Granger's Weather wisdom

High winds aloft---if the winds aloft over Denver at 9,000' or 12,000' are more than 20 knots, flying on the front range can be hazardous if the inversion breaks and the strong winds decend. Check the wind talkers in the mountains to confirm. Perhaps you can go towing?

Low pressure troff---If the barometric pressure is +0.05" or higher between Grand Junction and DIA, a pressure gradient exists and the winds may be from the west or downslope.

Shifting winds---You will experience shifting winds before they become catabatic or downslope winds.
