CLA, you indicated that in the mid 30's we could expect rain but at 1,500 feet it would likely be snow. I have always wondered what the convertion factor is for calculating temperature at various altitudes. During the winter I try to estimate the temperature/percipitation (hopefully snow) on Gunstock based on the forecast for Gilford. Assuming the temperature in Gilford is 35 (@ 500ft), what would the temp be at midway up Gunstock (1,000 ft) & at the top (1,950 ft). - is there a rule of thumb you could share?
