I've noticed that when flies gather on the screens it's about to rain. A ring (halo) around the moon is good sign of rain in the next 24 hours.

For day to day weather reports I gather from the local TV & radio stations & split the difference. When it gets more serious I also check MODOT (Missouri Dept. of Transportation - other states have a variation of this) for road conditions.

I've given up on the long forcast indicators (length of wooly worm hair or animal migration changes.) They don't seem to pan out.
