I use this weather graph during my morning meeting. Each day, my weather helper decides what he/she thinks the weather is like today and colors in one box on the graph. We count and do other activities as the graph becomes filled in and then we keep each month's graph in the science area to compare month to month.
Hope this graph is helpful for you!
Note: This graph is intended to be printed on LEGAL-SIZE paper so that there are enough spots to be colored in for each type of weather (to accomodate Western PA's very wet Spring and very snowy Winter).
