Very impressive cold signal here.

It's quite frustrating in the spring when a sunny morning becomes a cloudy afternoon and then clears out again when the sun goes down!

@TT-SEA kind of satisfying though that the reason i came up with is an actual thing. makes me feel less schizophrenic

I can tell you that when the ECMWF greatly diverges from the EPS... the next run usually corrects the problem. I am pretty sure the 12Z ECMWF will be much colder than the 00Z run. This is the extent of my knowledge.
