THEN ANTICYCLONIC SOUTH-WESTERLY TURNING CYCLONIC SOUTH-WESTERLY
NEAR THE END OF THE PERIOD

The general pressure situation for the period 21st to 31st July shows
LP to the N, NE and E of the country. HP lies to the W and NW of
Britain. The resulting NW airflow has small disturbances coming into
the W'tern seaboard. During this time, cool air covers the British Isles
with sun and showers for most areas. In the later part of the month,
LP deepens and stretches from N Ireland across Scotland to SW
Scandinavia. HP stretching N/S in the Atlantic to the W of Ireland,
pushes into Biscay. At the same time, HP builds up over France and
the near continent. Winds are generally W in the western half of the
country, and SW in the central and eastern parts of Britain. During the
second part of the period, England could have warm and sultry weather
as the SW winds bring in warm, moist air from the continent.

to the W of Ireland. A LP centre lies to the N of Scotland, and a

fronts lie either in the Atlantic W of the HP or over the continent
from Spain up to Germany. High humidity lies over Ireland and to the
W of Ireland - dryer conditions lie over the North Sea. 500mb LP centre
lies to the N of Scotland and upper-air winds are W in the west of the
country turning SW in the extreme E of the country. Rain is expected
to the NW and W of Ireland, the rest being mainly fair. Temperature
distribution has cooler conditions in the NW and warmer in the SE.
Strongest winds expected in the NW and W of Scotland later.

from the W over the whole country. 500mb LP centre lies to the N of
Scotland and has a trough stretching SW'wards down the W coast of
Ireland. Upper winds are SW in the south-west of the country, turning W
in the south-east of the country. Upper winds are W over Scotland. Rain
covers Scotland and the rest of the country has sun and showers
spreading E'wards. . Temperatures are cool in the NW and warmer in the
SE of the country. Strong winds are expected to the NW of Scotland due
to the depression to the NW of the country.

secondary on its S flank moving towards SW Ireland. HP lies to the E and
NE of Britain. There is a possible disturbance to the NE of Scotland
and another disturbance coming into SW France. The position of fronts
shows a warm sector over Scotland and Ireland and another set of fronts
stretching from SW Ireland to S Biscay moving NE'wards into the SW of
the country. Humidity is high over the country except for a dryer area
in the S and SE of England. 500mb LP lies to the N of Scotland and a

and SW England. and also to the NE of Scotland. Dryer over S North
Sea, and dryer again to the W of Ireland. 500mb winds generally W over
the whole country. Rain expected along the Channel and to the NW of
Scotland. Otherwise sunshine and showers over the rest of thecountry.

This is a comprehensive forecast comprising a number of factors to
describe the weather. Each factor has been calculated individually
without deducing from other factors. The calculations require a lot of
work and the massive reading load isn't worth the effort under normal
weather conditions. This is, then, a one-off forecast to give the
forecast-user an idea of what the the forecasting method can do.

The British Isles has had a lot of cool, showery weather over the past
few weeks and there is much anticipation for a change to warmer
conditions. A gradual change can be expected during this period when HP
moves across the country into the continent. Warm, moist SW winds then
blow across the S and SE parts of the country. That brings sultry
days and some thundery days to the SE, especially towards the end of
the period.

For August, the general chart covering the 31 days shows a weakening
generally of the Iceland LP so that W winds over Scotland will be less
frequent. There is a general strengthening of the LP near the Channel
so that E and SE winds cover the S half of Britain bringing warm humid
days with thunder and heavy rain to the south. With HP stretching
from Poland to Scandinavia and the Azores HP stretching up to Northern
Ireland, there could be some days when both systems join up over
Northern England. That would bring us some of the weather we are
looking for. But that is only a general view of the weather for
August. Let's wait for more detail a bit later on.

Cheers, Keith.

During the
second part of the period, England could have warm and sultry weather
as the SW winds bring in warm, moist air from the continent.


Huh???
