Fair Isle 09z 230deg 18kt 20km FEW ST 1500 BKN SC 3500 OVC AS 10000
+4.4/+0.8 1004.2hPa +2.4/3hr
and at 06z +5.8/-6.5 giving 41% RH
Yesterday afternoon/evening interesting as small developing low
tracked ENE between Fair Isle and Sumburgh - eventually leaving us in
a F9 NW'ly.
1600z aircraft being vectored onto an approach for 09 at Sumburgh
queried surface winds. Was told 120deg at 20kt. The pilot replied he
had SW'ly 50kts at 2500ft, range 7 miles. Shortly later commented
that between 2000ft and 1500ft, range 4 miles wind became 120deg. In
his words it was "Quite bumpy"!
Early Friday evening - after one aircraft had aborted a landing due
to cross-winds gusting 60kt and severe turbulence (only runway 27/06
is allowed after dark) following aircraft were advised not to attempt
a landing and once they had turned back for Aberdeen, Inverness etc
the airport closed.
Quite unsettled here this last week as four deep lows (pressure
falls/rises usually in excess of 10hPa/3hrs) passed close by.
Pointless exercise really, but pressure falls totaled 107hPa and
rises 128hPa in the seven days.

That wouldn't have been the Sumburgh Siren, Mary, calling the planes in,
would it?
