BRACKNELL (TF)
0615 W F1-2 45km - 1/AC T-011D-040
RMK: Ac is a mix of isolated patch of lenticular-looking type and Ac
floccus; also 1 oktas high-base Cirrus present: a glorious (if chilly)
morn. Hoar frost almost nil - air too dry.
Grass min currently -1.8; has been down below -3.=
0800 WNW F3 50km - 1/CI COTRA T033D-005
RMK: trace of Cirrus/ex-COTRA, otherwise clear blue sky. Feels quite
warm in sun/out of wind, but latter has picked up now and feels cold in
shade particularly.=
0900 WNW F4 50km - 1/CU T052D007
RMK: Feeling quite cold now, despite the strong rise in temperature; a
trace of Cumulus (Cu fra/hum) and all other cloud now disappeared. (Am a
bit suspicious about my dew point rise - but I assume that the increased
wind has mixed the air vertically quite strongly.)
[ OVERNIGHT DATA (18Z - 09Z):
screen min: -01.4 grass min: -03.5 precipitation: NIL
other data: Hard/paved surfaces dry/soil damp. ]=

1000 NW F3-4 50km - 2/CU T071D009
RMK: Cu fra/hum - good separation between elements, so still
bright/sunny.=
