BRACKNELL (TF)
0900 SSW F1-2 12km - 8/ST T147D136
RMK: Stratus base circa 600ft; light/sporadic drizzle/rain overnight -
most hard surfaces dry. A little misty first thing, but visibility
reasonable now; wind highly variable with near calm to ocnl F3 within a
few minutes.
[ OVERNIGHT DATA (18Z - 09Z):
screen min: 12.9 grass min: 06.6 precipitation: tr
other data: Warmest night of the year so far: Swifts seen returning for
the summer this morning. A hopeful sign!]=
1100 SSW F2-3 18km - 7/SC //CI T165D148
RMK: First shafts of sunshine appeared ~1045Z; can't tell how much
Cirrus above, but not thick as can see the disk of the sun quite clearly
as the Sc thins/breaks.=
1430 S F2-3 25km - 2/CU 3/CI T202D142
RMK: Cumulus mediocris (fairly vigorous), with 1 okta Sc and 1 okta Ac
also present - the Cirrus showing marked tufting. Over the past hour,
the Sc has 'gone convective' and within past 15 minutes, total cloud
cover reduced from 7 to 4 oktas: now occasionally sunny - pleasantly
warm / humid.=

1800 SE F2-3 30km - 1/SC 4/AC 8/CICS T205D132
RMK: Am almost tempted to put 'FU' in the weather slot as the dreaded
BBQ's have started up; The Sc is Cugen; the Ac is a mix of thin/well
broken and one area (probably lower) of quite thick appearance. The
thick Ci/Cs has spread in over the past 60-70 mins.
[ DAYTIME DATA (09Z - 18Z):
screen max: 21.4 precipitation: NIL
other data: first time to 21° this year: last year (2004) we reached
this temperature on the 24th April. ]=

1800 SE F2-3 30km - 1/SC 4/AC 8/CICS T205D132

[WR] 1840Z -RA (less than one minute-worth) from unstable medium level
cloud - could be high-base TCU I suppose: certainly the Ac in the sky at
present looks quite unstable (Ac cast/flo).
