I woke up this morning and wondered if I slept for a few days, instead of overnight. When we watched the weather report last night before turning in, it was pretty distinctly calling for a high pressure system to sit over Illinois for the better part of the next week, with little chance of the winter extremes. Yet, when I looked outside, it looked like we had a pretty nice snowfall.
Now, I don't believe the weathermen anymore than the next person, but the maps showed no real clouds, so I was immediately intrigued. After a shower to wake me up, I looked out and figured it out:
It has been pretty mild over the past couple of days - right around 32 degrees. The ground is still snow covered. So, overnight the temps remained steady, and the moisture came from the snow on the ground - fog, if you will. But it was just cold enough to freeze the water vapor on the branches and leaves, and there was a VERY slight breeze, so one side of the trees got more of the accumulating frost than the other.
At least that's my layman's version of how it happened. If you are a meteorologist, or just a weather junkie, feel free to correct me!
Anyway, it looks really nice on the trees, and I tried to take a few pictures. My camera is mediocre at best (a new 13 MP camera is en route, but hasn't arrived yet), so the shots are the best I can do.
Hope you enjoy them.
