Pressure building briefly next week
Hopeful signs of a couple of fair days

Temperature: 10.9 Weather: Showers

Autumn has arrived in style in the last week; can you believe it was only 7-days ago that temperatures were regularly getting into the 20's?

However, we have to deal with the cards as dealt and so the focus now is on when we might see an improvement in the weather.

You will know from my Look Ahead videos that I have been hinting that we might see something of a change around the 17th/18th October as pressure starts to build, in conjunction with the MMJO entering phases 7 and 8.

But there are hints of a rise in pressure in the middle of next week too.

The chart below shows the 4-day 500mb height anomaly from today through to the beginning of Monday. The blue colours showing where heights are below normal and highlighting the trough extending from northern Scotland, through the west of the UK and Ireland.

Now look at the chart at the bottom of the page. This is the height anomaly from Monday through next Thursday. Notice how the yellow colours ar east of the UK, the blue has retreated west and white affects the whole of the UK and Ireland.

This hints at the building pressure and the possible settling down of conditions.

But for now it's on with autumn!
