Cold Night Ahead
* Near-perfect radiational cooling conditions will allow temperatures to fall like a rock tonight. Radiational cooling occurs when there are no clouds. This allows the energy that the earth's surface absorbs from sunshine during the daylight hours to radiate off into space. Clouds serve to hold some of that energy in, keeping us warmer than we would be otherwise. Temperatures across much of our area will fall into the middle 30's. There could be a patch of frost or two out in a low-lying area, but widespread frost does not appear likely.* Warm tomorrow; highs will reach the middle to upper 70's in most locations. But, the radiational cooling effect will kick in again tomorrow night, and we'll see temperatures on the chilly side again.
* Warm weather will last through the weekend. Highs Saturday and Sunday could reach 80 degrees, with mostly sunny skies. There could be a few showers or thunderstorms late Saturday and into Sunday. There is growing evidence, however, that our rain chances this weekend are going to be rather small. We'll keep our fingers crossed but our hopes low for some rain.
* I went for my afternoon walk around downtown Meridian today and couldn't help but notice some of the fall color showing in the leaves. This is my favorite time of year in the world of weather, but I do hope that we can get some rain in here before too long.
