High Heat Index Days by County, 2011
Layer displays the percentage of weather observations in 2011 with high heat index values (103F or higher) by county.
PRISM 30-Year Average Minimum Temperature, 1981 – 2010
This layer depicts average annual minimum(low) temperature based on data from 1981 to 2010. Data was obtained from the PRISM Climate Group at Oregon State University. PRISM models climate information using a process which incorporates a digital elevation model. Monthly average data is also available.
