a feather tied to a string and hanging from a stick ...
feather is wet -- raining
feather is moving --- windy
feather is invisible -- night
feather is white and covered in ice --- OOPS
Sorry, just in one of those moods tonight. You've got some great answers above but i thought some levity could help --- we usually look at the long range and couple that with a general idea of what the *typical* patterns are for that time of year. We always bring shorts/capris, jeans, t-shirts, sweaters/hoodies, ponchos. If we're coming in the winter --- we will have a few heavier items but even a cold day in Disney will NEVER be as cold as it is at home (there was one day when the TV was telling us that it was in fact warmer in Anchorage that day however --- i think the feather would have been stiff that day!!)
