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?

Front Range Pressure Difference. This is the difference in barometric pressure between DIA and Grand Junction . Although there are other factors, the stronger the front range pressure troff becomes, the more likely west or tail winds become at our flying areas on the front range. The number will be green if the pressure is higher on the front range. It will turn yellow if there is a slight troff ( neg .5--- neg .15 ) and red if there is a strong low pressure troff on the front range ( <.15" ). You can see this anywhere on Parasoft' web site on its header.

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