PKPF68-77, If you were an aerodrome Met Forecaster, I bet our paths have crossed!
To answer your question, I'm sure ATC would not DREAM of issuing a "Trend" forecast. That's why, with the sad dparture of you guys from most UK aerodromes (many years ago), said airfields ceased to issue Trends on their METARS. Gatwick is a typical example.
And, by the way, now that Rwy 23L at LHR is closed for good, is Stansted the only airfield in the South of England with a decent-length runway if the wind is, say, 190/35G48?
