Rockies ridge has been the pattern for a while.. +6F anomalies for almost a year is impressive!

12z GFS back to bringing in some cooler air in the long range! Better than the blowtorch yesterday, but it is really flip-flopping! Euro 12z will shed light, but it keeps it pretty warm/hottish on previous runs.

We all know how this ends.

Ens are pretty rough. EPS goes cool for a bit around labor day before running back the heatwave we're in by late next week. CMCE keeps things cooler with more backdoor fronts. GEFS is a bit of a mix between the two that keeps us on the south side of any fronts, but has colder air up in PA.
