With the attention given to the number of 100 degree days this year, we have compiled a list that includes both automated sites as well as cooperative observation data provided by NWS volunteers. The official (and automated) sites of San Angelo, Abilene and Junction have complete records while some of the cooperative records contain sporadic missing data. The missing data may or may not have impacted the numer of 100 degree days at these coop sites.

Below is the compiled list from January 1 through December 31.
