Shortest TAF ever
EGTE 252256Z 2600/2602 25020G35KT 9999 SCT025 BECMG 2600/2602 26015G25KT PROB30 TEMPO 2600/2602 7000 SHRA
Just 2 hours long!
And it isn’t related to AD opening hours because EGHE is most definitely shut 2600-2602

I ve also noticed some weird TAF periods this last few months.
I suspect to do with the COVID/restricted ATC hours of service and changes to associated working hours of other staff.
Regards, SD..
Yes; saw a few more short ones like that this morning.
But this is for an airport which is totally closed at and around the TAF period…
What is this

and if it means “from” why not use BECMG ?

FM is an official code in TAFs, but not much used in Europe. It appears to be much more frequently used in the US.
It means that from the given time, the elements after FM replaces the previous elements of the same kind. BECMG means a gradual change during a time period.
How is this possible, with the two airports so close
EGHI 220820Z 09002KT CAVOK M04/M04 Q1021
EGHH 220820Z 13010KT CAVOK 05/02 Q1019
What about these ones? They aren’t far from each other either:
EGKK 220820Z 10005KT CAVOK M02/M03 Q1021
EGKA 220820Z 13010KT CAVOK 05/02 Q1021
Fog banks at both EGHI and EGKK.

They have same elevations and very close to each other but:
- EGHI is more inland with less wind from ground friction (and maybe extra later from IoW & Solent) and very cold ground, there is a high risk of freezing fog
- EGHH is near sea and windy (benefit from more night sea breeze, in CAVOK night you still get a hot sea and cold land after sunset), I would still expect EGHH to have a risk of advection fog as moist hot air go over cold land
If fog ever decided to appear (which it did not as it CAVOK ), I would have expected EGHH & EGKA to be foggy 1st (even if it’s windy) then EGHI & EGKK 2nd !
Do you have the next METAR?
In coastal areas, you don’t have to travel far for large temperature differences. Quite often where I live (near the coast) it can be well above freezing, but go a mile or two inland and there’s a hard frost.
Sometimes when riding my bike to/from the office, I’ve felt a definite boundary between cold and warm air, too.
