Diary of highlights

1st - 4th After some outbreaks of rain or
showers on the 1st and 2nd a dry two days followed with
good sunny periods, although it was often on the cool
side.
5th - 10th With low pressure close by to the north
or north-east a rather unsettled rather wet period ensued.
On the 5th heavy thunderstorms in the West Country gave
two inches of rain at Newquay (Cornwall). After some scattered
showers on the 6th, heavy thundery rain affected a number
of places particularly in the north and east coast counties
down to the Wash. Temperatures were in the cool category,
though with good sunny periods especially in the south.
Funnel clouds were seen off the Cornish coast and near Shoreham
(West Sussex) on the 8th. Redhill (Surrey) recorded -1.8 °C
early on the 9th a near record for the south-east region.
11th - 13th Rather cool,
mostly cloudy few days and generally dry, apart from
some isolated light showers.
14th - 16th A
mainly cool, very wet spell occurred as a depression in
the south-west approaches took up residence over
southern England. Rain and showers often heavy and
thundery broke out in many places.
17th - 20th After showers cleared from the east coast,
a drier regime prevailed, but with some patchy rain in the
north. The south became very warm with good sunny periods
and Herne Bay reached 27 °C on the 20th.
21st - 26th Virtually dry as high pressure sat close
by giving long sunny periods in most parts. During the 24th
to the 26th it became hot in many areas especially the south.
Thundery rain affected north Wales early on the 26th and
north-east England later that day, as falling pressure heralded
an end to the heatwave. Some thunderstorms also touched
East Sussex and Kent in the evening. At Barbourne near Worcester
a high of 32.6 °C was reached that day, the highest
for the UK so far this year.
27th - 30th After some
thunderstorms moved away from east coast counties and
East Anglia early on the 27th, a relatively cooler,
fresher and more changeable weather pattern became
established. Sunny spells alternated with occasional
outbreaks of rain or showers, some of these were
thundery over the Midlands and Eastern England later on
the 29th.

Changeable and rather cool conditions prevailed
throughout the first 11 days of July. Winds blew mainly
from the north-west and days of sunny periods and
scattered showers alternated with more cloudy spells of
weather with mostly light rain.
High pressure
advanced from the west to give more settled conditions
from the 12th to 14th, but there were large amounts of
cloud.
From the 15th to the 18th a depression moved
east across the south of England, with a band of rain
pushing north across Scotland before retreating south
again. A following ridge gave fair weather in the west
on the 17th and east on the 18th.
A depression near
Iceland caused a potent warm sector to cross Scotland on
the 19th, with wet weather, especially in the west where
Lusa on Skye recorded 56 mm of rain.
High pressure
then moved north-east across the country and gave more
settled conditions from the 21st to 25th. There was a
gradual transition from cool and clear to warm and humid
conditions. The best day was the 22nd, which was clear
and sunny in many places.
On the 26th and 27th a low
moved north across Scotland, bringing cloud, high
humidity and outbreaks of thundery rain.
The last
three days of the month saw a return to a changeable
south-westerly regime with an alternation between bands
of rain and bright and showery conditions.
