WEEKEND WEATHER FORECAST
Issued: 1000 Thursday 6th March 2008

FRIDAY:
A cold front clears southeast England on Friday morning, with low pressure remaining to the northwest of Scotland. Troughs will be embedded in the strong westerly flow, these bringing showers, most to the north and west. Increasing winds bringing gales to Scotland, Ireland and parts of northern England.
Early rain across southeast England and East Anglia should clear into the continent by mid-morning. Brighter skies then follow through much of England and Wales. However, there will be heavy showers developing across parts of Wales and northwest England in the afternoon, a few of these penetrating eastwards so just about anywhere could catch one. Becoming windy across northern England too.
For Scotland and Ireland it will become increasingly windy through the morning with gales developing. Frequent, heavy, blustery showers will occur, these turning to more persistent periods of rain through Scotland.
Winds will be W 12-15kt (F4) becoming WSW 15-25kt (F5-F6) across southern England and Wales. W-WSW 25-35kt (F6-F8) for northern England and SW-W 27-45kt (F6-F9) for Scotland and Ireland.


SATURDAY:
A cold front pushing eastwards through Saturday with low pressure still sat to the north of Scotland. The front will become increasingly slow moving in the afternoon. An occluded front moves into Scotland in the afternoon with a strong southwest to west flow everywhere.
Rain associated with the front affecting much of Scotland and Ireland in the morning. This reaches northern England, Wales and southwest England by late morning, then the Midlands and southeast England in the afternoon and evening. Some of the rain may be heavy at times and will be accompanied by blustery winds.
Following will be heavy showers for Scotland and Ireland, and again it will be windy here too. The showers merging to longer spells of rain for Scotland.
Winds will be SW 20-30kt (F5-F6 locally gusting F7) for England and Wales, 25-30kt (F6-F7) for Ireland and western Scotland.


SUNDAY:
A more unstable westerly flow for Sunday. An upper trough passes through intensifying the showers. Bands of showers passing through on the wind, ahead of a warm front approaching western Ireland later.
Sunny spells and showers throughout the day across Scotland and northern England. The showers probably heaviest and most frequent in the morning, and some of them wintry too. Further showers across the rest of England, Wales and Ireland in the morning, some of them wintry here too. However, there will be a tendency for them to fade in the afternoon as cloud increases over Ireland bringing rain here towards the evening.
Winds will be generally W 14-18kt (F4-F5) for England and Wales, perhaps W 20-25kt (F5-F6) for Scotland and Ireland, these easing and backing for a time later.

Looking at the Met Office synoptics today, the low on Monday is going down to 945mb. :?

Not even sure I would want to be working down below with the hatches closed in that !!

Apparently in 1967 one came through just below sea level.

Seriously though I'm amazed by how much the pressure affects the height of tide. My relaunch, which depends on a high spring tide, can be scuppered by high pressure reducing it. And a strong northerly wind ( the tide comes north up the west coast from Galway) can likewise reduce the height of tide by 2 or 3 feet

This is an influence that is often overlooked.

I know for a fact that the atmospheric pressure was about 2000hPa the last time I ran aground.

apperently the lowest atmospheric pressure recorded in the UK was 925.6 mbar at Ochtertyre in Perthshire in 1884.

From the same source:

The lowest barometric pressure reading in the world occurred in the eye of Typhoon Tip as it moved across the Pacific Ocean to the east of the Philippines on 12 October 1979. The pressure fell to 870 mb.

There's a joke in there somewhere about checking your Ochtertyre pressures more regularly..

I regularly measure the pressure to correct flash point readings. Our instrument is usually somewhere between 750 and 770 mm Hg.

I have seen it as low as 740 mm Hg and that was commented on.

This morning I checked and it was 722 mm Hg, that's low. I don't know what it is in the old money.
