WE can't control the weather, true enough.
And it appears that we also can't predict it much more than 24 hours in advance.
Like here in Glen Rock today. Saw the forecast (for today) last nite around 6:00 PM. Rain, it said, and highs in mid-to upper 40's.
This morning, a much different forecast for today--rain in the AM, snow developing mid afternoon. High only 38!!
And that's just 24 hours, not 10-15 days!!
Anyway--christy'smom:
Don't even pay any sort of attention to those long range forecasts. It may well rain on XMAS day--and it may well NOT rain on XMAS day.
For your trip, I certainly hope it is nice weather!!!
