Default [WR] ... Bracknell: cloudy morning, fine afternoon

....Warmest day of July so far with day maximum of 24.6degC. Cloudy
morning - thick SC, with a period of thick AS above (just on the edge of
developments further east), then gradual breaking of cloud to CUSC
through afternoon - fine/warm sunshine with temperatures responding
accordingly.

.... as regards below:

Don't normally look at the various web-based forecasts, but noticed
today that the high for Bracknell (Met O and BBC ... same feed), was
just 20degC. This is therefore 3degrees below actual. We used to

notice
(when we were hand-amending stuff for specific customers), that the

web
data were on the 'cold' side in these situations, so it may be that

that
bias is still there. The forecast maxima for the next 4 days a
20, 21, 19, 23 (Saturday to Tuesday), so it'll be interesting to see

how
these pan out.



.... an error today of 4C in day maxima; the minimum also 3C too low
(forecast 12degC, actual 15degC).

All this despite the actual weather (broken cloud/sunshine symbol) being
essentially correct, so it looks as if the cold bias is still there.
(Incidentally MetCheck and TWO only did marginally better with indicated
maxima around 21degC.)
