NPS Petrified Forest National Park is a semi-arid grassland. Temperatures range from above 100° F (38° C) to well below freezing. About 10 inches (25.4 cm) of moisture comes during infrequent snow in the winter and often violent summer thunder-storms. Animals and plants are adapted to extremes in temperature and moisture. You should be ready too. Check out the forecast before you arrive and plan accordingly. Petrified Forest National Park at the Weather Channel |
