The 00z GFS op was an interesting case scenario, with some hot weather lifting a loose CET estimate up to around 18.0*C by the midpoint of the month, only for relatively cool conditions to then bring it down into the mid-17's by late in the third week.
Average conditions thereafter would leave us with a high 16's final figure... but this is the warmest op run I've seen since the month began and the 06z was nowhere near as toasty.
Still, I find myself wondering if 15.7*C was at least a little pessimistic. It depends how well we can escape Atlantic westerlies once the potential warmer/hotter spell has wound down.
