with the reference in the TAF below , I was looking for the VIS at 0500 UTC and I was little bit confused because of the " TEMPO "
And the TAF was
LHBP TAF (FT)140400Z 141206 34006KT 9999 BKNO45 TEMPO 1215 VRB10G2OKT 7000 SHRA SCT033CB BKNO40 FM1700 CAVOK BECMG 2022 VRBO1KT 5000 BR NSC BECMG 2201 1200 BCFG BR SCT002 BECMG 0104 0600 FG OVC001 TEMPO 0406 0150 FG VV001
According to the TAF at 0104Z VIS would be 600M, then we can see TEMPO at 0406 with 150 M VIS, so what VIS can we expect? Can we say it is 600M with possibility to be 150 M? Or we can say directly it is 150M?
