Windrush Weather

Today we are between two systems

Sunday 30th November
Saturday gave us a very wet morning followed by bands of light drizzle in the early afternoon before the sky began to break after the back edge of the weather front had moved off to the east. The daily rainfall total was 9.0mm. The cloud by day, and the modest westerly breeze, limited the rise in temperature to a peak of 10.6C, which was just 0.3C above average. The clearance of cloud in the late afternoon meant a cooler night although the temperature held up to a round 4C until just after 02.00 when it began to drop steadily to reach a minimum of -0.1C at 07.49 early Sunday. Usually under these conditions, at this time of the year, the thermometer continues to fall before sunrise, however, the thermometer began to very slowly rise after 07.49, reaching +0.1C at 08.00.

At the start of Sunday we were greeted by clear blue sky and the promise of sunshine, weak at this tome of the year, when it eventually rose above the horizon.

A temporary ridge of high pressure had again risen over the UK on Sunday, so a fine, if much cooler day ahead. The barometric pressure had risen 14mb since yesterday to read 1013.5mb at 08.00 and still rousing rapidly. During the afternoon, as the ridge topples to the east, the wind will back from the west to southwest and eventually south as the next low pressure system arrives off the west coast.

A secondary low pressure system,to that currently near Iceland, will form as the day progresses and drift over the UK for Monday, which will herald a wet and windy day.

Today is Advent Sunday. Every year the National Trust property at Avebury is dressed for Christmas. Over the next few days I will attach images of one such display taken four years ago. The House reopened yesterday after extensive repairs following the flooding in 2024.
