Hello. Autumn is the season of change, most noticeably with those

autumn colours on display today in Buckinghamshire, as photographed by

one of our weather watchers. Always helps when there is blue sky above.

Our weather is always changing regardless of the season. One of

those changes is taking place, we are losing last week's Easterly

winds and now a westerly wind. That means it's turning milder by day and

night but it does mean the return of Atlantic weather fronts, especially

to north-western parts of the UK. The reason, high pressure in Germany

and low pressure Iceland. Here is the first of those weather fronts

for Scotland and Northern Ireland through the night, the first part of

tomorrow. There isn't a huge amount of rain associated with this. Could

see rain over the hills of northern England and Wales as the night goes

on. The odd shower clipping Sussex and Kent. A lot of dry weather for

England and Wales. It's mild here, it's milder across the northern half

of Britain compared with last night. But the further south you are the

closer to that area of high pressure, and we are concerned about

fog developing, especially in southern England into tomorrow

morning's rush hour. Patchy, but could be dense in places, if there

are travel problems keep in touch with your local radio station. Here

is things in the morning. You can see the fog showing up here. Could

be patches too into Wales and the Midlands, East Anglia. Maybe still

the odd spot of rain over Snowdonia. Northern Ireland and Scotland, it's

a different set-up. It's a milder morning than this morning but it's

cloudier, breezier. There are some outbreaks of rain around. Again

there isn't a huge amount of wet weather with this weather system.

They'll gradually slip further South East during the day. Eventually for

you things start to brighten up Could be the odd shower in England

and Wales. Once the fog has gone many places will be dry and variable

cloud with sunny spells coming through. It will feel pleasant in

the sunshine. As we go through Wednesday evening our weakening

weather front may have patchy rain to parts of northern England and

North Wales, and then Wednesday night fog developing again in

southern England. That could be slower to clear on Thursday morning.

It's looking quiet on Thursday and Friday. Still maybe some weather

fronts clipping the far north-west of the UK. But a lot of cloud, it is

mild. The Met Office has a weather warning
