The foothills get little to average precipitation during the year. In the higher parts of the foothills, up to 1 to 2 feet of snow may build up over the winter. In the lower part of the foothills there may just be a couple of inches of snow in winter. In spring, the snow starts melting and many plants grow quickly making the foothills turn bright green. During the summer and fall, the foothills do get some rain. But overall, the land does start drying out.
High temperatures can range from the 80 to 90 degrees F in the summer to below freezing for much of the winter. Night time temperatures can get 20 to 30 degrees F cooler than the day time high temperatures.
