I'm looking at long range forecasts (Sep/Oct) for Stowe and Underhill and am curious if anyone knows of a long range forecast for anywhere up higher. Research has uncovered historical data for Mansfield, but that isn't really a good indicator of future conditions. The reason I'm looking is to help me decide which underquilt to bring along between a 30°f shorty and a 10°f full size. Difference is about 9oz and a fair bit of volume. Tempted to go with overkill rather than risk being cold, but I always like to see if I can find some data to base my decisions on rather than hunches
