GENERALLY COOLER IN THE WEST AND WARMEST IN THE SOUTH-EAST The general pressure situation for the period 21st to 30th June shows a LP area over Northern Ireland and NW Scotland. Cooler W or NW winds come into the country from the west. SW winds cover E and SE areas. There should be quite a few windy days especially off W Scotland. Over Scotland, Northern Ireland and W parts of England and also Wales there should be an abundance of rain and showers. A ridge of HP should bring an improvement on 21st, and a new ridge should build up into SW areas on 28th, moving eastwards across the southern half of the country by 30th. Otherwise, LP governs the weather and keeps HP to the S of the country.. Windy days are frequent for the W of Scotland. . Mild temperatures at first caused by SW winds last up to about 23rd then temperatures start to cool off on 24th to reach their lowest about 27th and 28th. This is caused by cool Atlantic air coming into the country behind a depression to the W and NW of Scotland. After that, temperatures begin to rise to reach a high on 30th. The run of weather starts on 21st when a ridge of HP comes into the country from the SW of England. Winds are expected to be light and variable, but from a N'erly direction in the extreme SE of England. Over Ireland and W Scotland, winds should have turned SW and rain should be coming in from the Atlantic. Elsewhere, it should be fine and dry. On 22nd, The anticyclone has moved into the North Sea but it still affects S, SE and E England. Cyclonically shaped isobars are into Ireland and Scotland. Winds come generally from the S and SW over the country. Rain is expected to fall in the N and NW of the country but fair weather should hold on in the S and SE. On 23rd, LP lies to the SW of Iceland and has a trough stretching E'wards towards SW Norway. A new surge of HP from the Channel northwards brings an improvement in the weather for England and Wales. Winds will be mostly W or WSW but light and variable in the southern half of the country. Showers are most likely in the W of the country. Fine weather is expected in the E and NE of Britain. On 24th, the HP of yesterday now stretches N/S over the North Sea and the near continent. A LP area to the SW and S of Iceland has a small secondary LP coming E'wards towards Ireland. Winds are S to SW and rain can be expected in W'ern parts. In the S and SE of Britain, bright intervals can be expected. On 25th, LP lies just to the W and NW of Scotland with a secondary near Ireland. The secondary is expected to fill as it moves NE'wards towards Scotland. HP lies to E of the country. Winds are mostly S turning SW later. Rain can be expected in the N and NE of the country, showers elsewhere. On 26th, a belt of LP stretches from Northern Ireland NE'wards towards SW Norway. HP is well to the S and SE of the country. Winds are SW. A belt of rain showers can be expected from Northern Ireland to Cornwall, but bright intervals in the SE. On 27th, a deep LP lies to the N of Scotland and a belt of HP runs from WSW/ENE along the Channel. Winds will be W or SW and rain will sweep across the country. It will be dry at first in the E, but showers will spread into these areas during the day. On 28th, once again a ridge of HP comes into SW'tern areas and moves slowly into the rest of England. A small LP could build up over W France bringing NW winds to SE England. Over the rest of the country winds should be light and variable. Some rain showers could get into the NW of the country and Northern Ireland. Improving weather over the south. On 29th, the HP ridge over England has not moved much. However, the LP over W France could have deepened drawing cooler air down the Channel. Winds should be light in the south - and W in the northern half of the country. Weather should be fair over most of the country but rain could come into the W of Ireland later. On 30th, the HP ridge has moved eastwards and now lies SW/NE across SE England and the North Sea. A deep depression to the SW of Iceland has cyclonically curved isobars into the NW of Scotland and Northern Ireland. Winds are mostly SW over the whole country. A belt of rain stretching from NE Scotland down to SW England moves eastwards. The next 10-day period lies in the month of July. Generally, for July, I expect an increase in the frequency of NW winds, because Britain lies generally on the cooler side of the HP over the Atlantic with relatively LP over the Norwegian Sea and Scandinavia. This would indicate a summer monsoonal weather-type for July. Cheers, Keith. |

Snip

This is caused by cool Atlantic air coming into the country behind a depression to the W and NW of Scotland. After that, temperatures begin to rise to reach a high on 30th. Snip I now have lost faith in your forecast as you seem to think mid to high 20's or even low 30's is "MILD". If you ate a strong curry would you call that "Mild". |

Will!, whether it's a week ahead or further ahead, it's still hard work as you
say. I'm also interested in the week-ahead forecast to see which important factors in the weather you have considered. So, Will, I'm a regular viewer of your postings and file them away each week. Keep it up Will. Cheers, Keith Will schrieb: Simon S wrote in message ...
