Today's Weather 2/1

Today's temperature was mild with a high of 37 degrees F and a low of 25 degrees F. The cloud cover was overcast throughout the day. The wind direction changed from NW to SSW later on in the day. Due to the rapid change in wind direction, I predict a low pressure system is moving in. I noticed the humidity on my way to class today and figured the relative humidity was somewhere around 90%.  Hopefully my weather handbook will arrive later this week so I can make more accurate observations.
