Let's assume I have a TAF that reads:
[...] PROB40 TEMPO 0815/0822 5000 -SHSN BKN008 OVC015 TEMPO 0822/0909 1000 SN VV003 BECMG 0902/0904 16012KT
Which of the
BECMG groups have a probability of 40%? All three because everything that follows
PROB40 has a probability of 40%? Just the first
PROB40 only means the one following line in the TAF? Or both
TEMPO ones, and
BECMG is again certain and not just 40% probable?
