Default Late Summer predictor

In the middle of July I gave details of a possible relationship between
temperatures of 24+c in the second week of July and the likelihood of

their
frequency during the remainder of July and in August. This connection was
first spotted by the late Colin Finch in the 1970s.The more such
temperatures occurred in the second week of July, the more likely a lot

more
would be registered during the rest of the summer.

This year there were 5 24+c days in the qualifying period and there

have
been 18 more since 15July. This is a rather disappointing result because
the average number is 25 when there were 4 or more such days in July's
second week .Nevertheless, the average is only 12 24+c days if there
were 3 or less days between 7 and 14 July.

Incidentally, the mean number of 24+c days in the peak holiday weeks

between
15 July and 31 August we-
!971 - 80 11.4
1981 - 90 17.5
1991 - 2005 18.9

These figures are all based on my readings here.

Footnote: - the maxima for the 30 and 31 August here are the highest for
these dates since before 1971. Yesterday was 26.5c and today, so far, is
31.0.
