Martin,

The forecast temperatures used to be way out for Penzance under these
conditions, typically close to the sea temperature (16) whilst in Mount's
Bay the mist often clears for a while (as it did particularly yesterday).
They 5 day forecasts used to be a joke in the spring here. During hot May
spells they were often 8 degrees out, and on a few occasions 10 degrees
(E.g. 15 forecast as opposed to 25 actual !). This May/June they were much
better.

The last 2 days
15th Forecast 18, Actual 20.4
16th Forecast 19, Actual 19.3

Still slighly on the low side, but much better than previous years.

I can only assume there has been some change in the way the figures are
generated.

Day maximum today 23.3degC (dew point currently / 18Z = 15.0degC).

The 7th day over 21degC this month, and the 32nd so far this year.

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.

Martin.
