Getting nervous weather?

[gilby]

we leave the 29th and I am getting nervous about the weather. Last time we went in December it was cold, jacket and mittens weather. I see weather next we is 64.

First off looking 10 days out is never a good idea.
Weather can easily change.
However around 72 is the average day time high for late November into December.
It very well could be much warmer or much colder which is why its better for parking purposes to wait until a couple days prior to look at weather.
Its not like summer where you know that its going to be hot.
I'm leaving on December 7th and my plan as of now is leggings and a t-shirt and most likely a jacket for the morning and evening.
I will adjust my bottoms a couple days prior if it looks like its going to be very warm or very cold but for me leggings are probably good if they low doesn't go below 50 and the high doesn't go above 78.
