Summary
We'll be honest, June 2017 turned out quite a bit different from what we expecting for some areas of the forecast. While we expected the temperatures to be above average, we were thinking they'd only be slightly so; in reality they finished quite a bit above average. The other story was the precipitation... coming off of a decently wet spring and an El Nino pattern establishing we figured above normal precipitation or at least near average. This again didn't pan out, we've got the latest details on how June 2017 finished up for Castle Rock below!
Only a few spots on the plains saw any decent rainfall, thanks mainly to severe thunderstorms. The rest of the state was between 1-2 inches below average on rain for the month! Some select areas were nearly 3 inches below average!
