METARS

IFR reported when there's a scattered layer below 1000' and vis 3 mi or greater. Should be MVFR. Scattered layer is not a ceiling.

It appeared to be universal. I looked at several airports

@rbusby
It seems that METAR conditions parser is taking (erroneously) SCT into account
instead of BKN (or OVC).
VFR, MVFR, IFR etc cliteria depend on visibility and CEILING.
Ceiling supposed for BKN/OVC clouds (not for SCT).

.... SCT clouds, BLU+ (is not IFR)
