BRACKNELL (TF) 0900 VRB F2 5000 BR 1/CU T085D070 RMK: The Cumulus very ragged - looks like it could have been formed from lifted / clearing fog from elsewhere; Also present are 2 oktas Ci - thin/high ~ 30000ft; Wind favouring a northerly point overall. A glorious morning, with the strong sunshine now feeling quite powerful, despite the high haze element in the atmosphere. [ OVERNIGHT DATA (18Z - 09Z): screen min: 04.4 grass min: 01.7 precipitation: NIL other data: Misty overnight; less than 3000M up to about 07Z - possibly a short period of fog in the early hours. ]= 1200 NNE F2-3 15km - 1/CU T126D073 RMK: Total cloud cover 3 oktas: in addition, there are 2 oktas thin Sc, 1 okta Ac, and 2 oktas Ci. A fine day - the sun feels warm, with little wind to spoil things.= 1500 VRB F2 18km - 2/CU 6/SC T141D064 RMK: Cu rather stunted - the Sc somewhat thicker thatn previous, but high and allowing insolation in the main. A pleasantly warm, bright spring afternoon.= 1800 NNE F2-3 15km - 1/CU 4/SC 7/SC T135D055 RMK: The Cu looks to be mediocris but as it is hidden by both the Sc and a rather hazy atmosphere, it's not easy to tell. The lower layer of Sc is ex-Cu; the upper layer of Sc is around 6000ft, and there may be some Ac above that. [ DAYTIME DATA (09Z - 18Z): screen max: 14.6 precipitation: NIL other data: Hard/paved surfaces dry; soil surfaces partial drying on top. There appears to be a little pocket of dry (low dew-point) air in the lower Thames Valley atm. ]= -- Martin Rowley: data via - http://homepage.ntlworld.com/booty.weather/metindex.htm Bracknell (Wooden Hill/Tawfield), Berkshire NGR: SU 854 667 Elev: 80m Lat: 51DEG23MIN30SEC(N): Long: 00DEG46MIN28SEC(W) |
