Click on any point on the map for a forecast for that point.

Then go down the page and find the Hourly Weather Graph in the right column. Click on the graph, it will open a page with an hourly forecast in graph form for 6 days out. 

Just a forecast tho changes allot as it get updated by NOAA data. 

I like using the weather channel .com and putting in Marshall California for my location. It's been pretty accurate for me.
