July 2018 C.E.T. forecasts and optional EWP contest

Recommended Posts

Changed my mind somewhat as latest guidance less robust for a cooling trend, still think it won't be any 2006 outcome but maybe 17.9, 57.5 mm the new call.

Will post a bit of a summary if I have time of all forecasts but it may not appear until Sunday morning. 

We have had some rather cool weather relative to our normals here in the past week to ten days, probably running 2-3 deg below average through that span after several weeks of anomalous warmth May and early June. The extreme heat has shifted to eastern North America for a while.

Me thinking July is going to be a scorcher.  Going with 18.9C and 50mm please.  Not a normal summer this year.

A stonking great 18.7*C and 42 mm please and I suspect I'm being a bit cowardly there!

18.7c and 35mm

I was thinking of drier but a few T storms may quickly blow that out of the water.

I will go with 18.4 degrees, very warm first half, not record breaking as we will see more of anticylonic overhead feature, rather than a humid southerly flow, becoming cooler in the north second half, but still a little above average, southern parts remaining above average throughout.

Another very dry month - wettest parts NW.

Summary of forecasts to date:

__ CET forecasts show two- or three-letter codes for forecaster followed by order of final version (earlier versions are not counted in that), and 

__ EWP forecasts show just two- or three-letter codes since scores there do not depend on order submitted to break ties.

Note for J10: According to my computer time, all these are on time or fall within a five minute grace period.

Oops I missed it, I'll go with 18.6 with low rainfall, perhaps about 25 mm.
