I just noticed that the weather shown on the airport page is one day old. Tried several airports, here is an example:
KSBP 221656Z 34009G17KT 10SM CLR 11/04 A3024 RMK AO2 SLP242 T01060039
But as I write this it is 231652Z.
I first noticed this yesterday, but thought it was just a temporary glitch. I was watching aircraft land in Aspen when the reported wx was something like 3/4 mile with snow. Certainly not approach minimums there 
Happy holidays.
I have noticed the same thing, took me a while to realize the wx is delayed that much. I usually hop over to www.wunderground.com for the real stuff. Why the delay?
