There are many places to get climate information online, but they aren’t always easy to find.  NOAA’s Climate.gov page has provided a link to a new interactive web source that contains a lot of their climate data sets in one place.  You can read the documentation on the source at https://www.climate.gov/maps-data/dataset/monthly-climate-conditions-interactive-map or go directly to the interactive map at https://gis.ncdc.noaa.gov/maps/ncei#app=cdo.
