"Weather" It's Right or Wrong

OK, so what's the deal with the weather?! Two days ago it was in the upper 70's, sunny and gorgeous. Yesterday it poured down rain half the day, then was overcast and chilly, in the upper 50's. Today it's supposed to get no warmer than 40F, but right now at 3:40 pm it's only 36F. And it's supposed to get down into the 20's tonight -- oh yeah, and might snow! And when it's not been cold or raining there has been this awful wind that makes it sound like the siding is coming off the house. I could live with warm or cold -- I just wish it would stay the same way for a whole day. Actually, I wish it would choose "warm" for this week, since I'm off.
