TAF YMML:
Derived from NWP model MSL pressure;
statistical aids to predict min temp,
max temp, and QPF, and probability of
precip, fog, low cloud, and thunder;
and also, from synoptically stratified
wind and weather climatologies

T
Q

Bass Strait:
Derived by adjusting Shoni Dawkin's
statistical aid to predict wind and
swell at Cape Otway to Bass Strait.
