yay, forecasting 18F where I'm going this weekend!
Last Feb I hunted snow geese in Missouri. It was 40F the whole month of feb. we arrived, flash blizzard and all the sudden windchill is down to -16F (thats NEGATIVE!) with us in layout blinds in 6 inches of snow!! the week we left, it jumped back up to 50s-60s and the snow was gone the next day.
