Thanks! Do you make any adjustments for cold weather?

No.
Using slower reducer also helps flow out at the expense of recoat time. Even in cool(70 or less) shop I use medium temp reducer to get better flow out. It adds a few minutes between coats but makes it easier to get a bit better result.
For acrylic urethane I use a turbine HVLP system which gives a big pattern and has no water in the air. I can't make myself use my $400 gun for polyester topcoat so I do get a few fish eyes in that.
FWIW
