~North American great plains warm as a result of late April CTNP disintegration
We remember NOAA's cooler in the central plains May June July temperature outlook:
Since EH2r expected not as strong as last year strongest CTNP vortice, 2019 vortice withered away remarkably fast, this made the Great Plains not as cool as both NOAA and ECMWF suggested (here was EH2r criticism).
One reasoning behind not agreeing with the great models outlook was the Canadian Main CTNP (Cold Temperature North Pole) did not have a strong prolonged build up similar to winter of 2017-18. The initial sun disk readings taken in February to Mid-March 2019 were in 4th place warmest, then vertical sun disks dramatically shrunk in size severely reducing average elevation decimal levels sun disk sizes to last place, I was aware of monitoring a smaller vortice within the Tropospheric Polar Vortex, smaller vortices are usually colder. This changed my estimate of summer climate to come, from similar to last year, to different, warmer in most regions.
The latest GFS short term forecasts call for the opposite of the longer term outlook above:
ENSO is still a main concern, this weather may change, but still ENSO lingers, hesitates to take a turn up or down on the warm side. This latest weather picture may last and build up much hotter. WD May 11 2019
