Just a thought. This last weekend we were warned that a major winter storm was about to hit our area. This took me as a surprise because I had checked an online weather site less than 48 hours prior and nothing of the sort was predicted. My wife informed me of the forecast on Sunday - that it was supposed to start snowing Sunday evening and continue through the following day, leaving 10 or more inches of snow. I watched and waited until I retired Sunday night, wondering if schools would close and how long it would take to clear my driveway.
I woke up to find a modest 2-3 inches of snow - a minor inconvenience, not quite what was predicted.
I've seen this pattern repeated over and over, as has anyone who has tried to plan a spring camping trip. Listen to the weather reports on one TV station and you may or may not hear the same thing on another. Online weather services often show different forecasts. If you are looking at the next day forecast, the accuracy is usually pretty good. If the forecast is for three days out, not so much. If the forecast is for five days out - well, you'd better check back in a couple of days.
