Diary of highlights

1st to 9th Mostly warm with sunny periods
but rather unsettled with rain at times, as weak Atlantic
fronts and shallow low pressure centres crossed the region.
The Midlands and the south-east had thundery showers on
the 1st, with Shepshed(Leics) catching 39 mm in 1 hour.
Widespread storms affected east and south-east England early
on the 2nd, 60 mm being reported from St Leonards which
caused flash flooding in places. Generally showers and outbreaks
of rain affected many parts from time to time, some turned
thundery in association with a secondary low which tracked
north-east across the region on the 8th.
10th to 16th Generally more settled as high pressure
built close by. After the clearance of thundery rain from
some central and eastern areas on the 10th, and some scattered
showers in the north-west on the 11th and 12th, it became
mostly sunny dry and very warm everywhere. An area of thunder
affected the Channel Islands and coastal areas of south-west
England on the 14th. It became hot in places during the
15th and 16th. Thundery showers broke out in south-west
districts later in the evening of the 16th.
17th to 20th During the 17th heavy thunderstorms
tracked from the Midlands to Lincs and north-east England,
also from south of London to the Essex coast. The rain was
torrential in places, with flooding and lightning strikes
disrupting railway networks in the noth-east, especially
the Tyne and Wear Metro. 24 mm of rain fell in an hour at
Coningsby(Lincs). A breezy few days followed, with rain
and drizzle in north-west areas. Mist and coastal fog affected
the south-west and south Wales during the 19th, thereafter
a ridge of high pressure gave a warm sunny day on the 20th.
21st to 23rd A thundery spell occured, especially
overnight the 22nd/23rd, as a low moved eastwards over Scotland.
Some places reported pronounced lightning. The temperature
rose to 30.5 °C at Shepshed(Leics) on the 22nd, the highest
recorded in the UK so far this year.
24th to 26th A relatively quiet period as a weak
ridge stretched itself across the region from a high over
Scandinavia. Early patchy mist and fog soon gave way to
sunshine and warm temperatures, counties bordering the English
Channel had the odd thundery outbreak overnight 25th/26th.
27th to 30th Changeable with thundery rain at times.
Heavy thundery outbreaks affected much of the north and
east of England later on the 27th, followed by two days
of very warm sunny conditions. Rain in the south later on
the 29th spread north during the 30th delivering copious
amounts with thunder, particularly over the Midlands northwards.

| Diary of Highlights |
South-westerly winds blew throughout almost all of June,
bringing a rather dull and wet month to parts of the west,
but dry, bright and warm conditions to the east. Unsettled
and showery weather predominated, but there were also
interludes of warm and sunny weather.
The first spell of hot weather occurred away from the
west coast on the 1st, when temperatures at Kinloss and
Lossiemouth reached 26 °C.
Then followed a long period of unsettled south-westerly
weather, with bands of rain and showers. However, most
of the rain bands passed through during the night and
on many days there were only a scattering of showers.
The second spell of more settled weather occurred from
the 14th to the 16th, when an anticyclone developed over
England and pushed a ridge towards Scotland.
Changeable westerly weather returned from the 17th to
the 23rd. The most stormy weather occurred on the 17th
when a deep depression passing to the north-west of Scotland
brought gusts of 58 m.p.h. to Lerwick and Sella Ness.
The strong winds abated only slowly over the next couple
of days.
The third fine spell lasted from the 24th to the 26th
as an anticyclone developed over England and moved to
the North Sea. The temperature reached 26 °C at Lochcarron
on the 26th.
A front brought much rain to the south-east on the 27th,
with about 35 mm being recorded at Prestwick, Bishopton
and East Kilbride.
On the 29th and 30th winds turned into the east as the
next Atlantic depression headed towards Biscay. It was
fairly sunny in the west, and on the 29th the temperature
at Lochcarron reached 25 °C.

June was a rather unsettled month with a mixture
of long sunny spells, interspersed with showers, which were
at times thundery in nature. However overall it was a warm
month and on occasion very warm.
1st to 5th On the whole the start of the month was
dull with rain and showers affecting most days. Daytime
temperatures were around normal though by night temperatures
were warm. The 2nd of the month was a sunny day, with many
areas recording daily sunshine values in double figures.
6th to 8th Conditions improved across the province
with plenty of sunshine and warm temperatures recorded throughout
this period. However some heavy showers, accompanied by
thunder did develop during the early evenings of the 7th
and 8th.
9th to 12th Although there were prolonged spells
of sunshine, temperatures became cooler than of late. It
was also a rather unsettled period with blustery showers
along with some hail and thunder affecting many areas, especially
on the 9th and 10th. Western areas and some extreme south-eastern
parts of the province recorded some heavier downpours on
the 9th, recording about 25 mm of rain on this day alone.
13th to 20th High pressure dominated much of this
period bringing very warm and sunny conditions throughout
Northern Ireland. Indeed many areas recorded over 20 °C
on the 14th and 16th. On the whole it was fairly dry though
some showers did occur which were locally quite heavy on
the 17th and 19th.
21st to 26th As well as being one of the driest spells
of the month over this period, temperatures were also very
warm. Many areas recorded their warmest daytime temperature
for the month of up to 23 °C on 25th, which was also a very
sunny day with over 13 hours of bright sunshine recorded.
However heavy thundery rain tracked across the province
on the 26th and in some areas daily rainfall accumulations
would have around 25 mm in total.
27th to 30th The 27th was a cool, dull day with some
showery outbreaks of rain, which were at times heavy. While
conditions on the 28th and 29th were very warm, dry and
very sunny. Indeed over 30 hours of sunshine were recorded
during these two days in some coastal areas of Co Down alone.
In contrast the last day of the month was cooler and duller
and although much of the province remained dry the south-eastern
part of the province was affected by a belt of rain which
moved slowly up from the south. Many areas in this region
recorded daily rainfall totals of around 25 mm or more.
