However, by the end of this week, things will have evened
out a little bit. But certainly to start the week, we've got
a big North-South contrast with the temperatures cold air
ensconced across the south, whereas it is much milder
across Scotland and Northern Ireland.
The bigger picture shows why, with high pressure dominating
across the south. So the weather has been stagnating.
We've had a bit of an easterly drift, bringing the colder
air further north. Low pressure up to the north and
west. Still a breeze is bringing milder air in from the
Atlantic. That situation will remain the same for the next
couple of days until this cold front sinks southwards
through the middle of the week.
The high pressure is still nearby, but it's building in from
the west and will, as I say, even the temperatures
out by the time we get to the end of the week.
A temperature map much more evenly distributed by
Friday. Another way of looking at the temperatures on this
graph here showing the temperatures for Fort William well
above average to start the week. A bit of a dip as that cold
front sinks southwards before perhaps starting to
rise again towards the weekend.
Compare and contrast with Southampton on the south coast,
five or six degrees at best and steadily
rising as we go through the week.
So much closer together by the time we get to
the weekend. Okay, let's look at the way that day by
day, Tuesday will certainly still have that contrast with a
frosty start across parts of England and Wales, where skies
have been clear may not be quite as cold across the
south east and East Anglia with more cloud in here, but as
well as a frosty start for parts of the Midlands, eastern
England, South Wales, south west England, there will be some
dense patches of fog around as well, which could take much
of the day to clear further north a lot of cloud and that
cloud at times thick enough for some drizzly, right chiefly
over the hills of north west England, south west Scotland
and Northern Ireland, but will be quite a dank and drizzly
day in western parts of Scotland to the east of
the hills and mountains.
However, some brightness across Aberdeenshire and
maybe also further north through Caithness, we could see
temperatures getting up to 12 or perhaps even 13
Celsius, whereas further south even where it's sunny, only
four or five Celsius. And if the fog sticks, well, we'll
struggle to get much above freezing pretty rapidly.
That frost will return across the south under the area of
high pressure as we head through Tuesday night.
But it's then when we start to see that weather front
drifting southwards, mixing things up a little bit, bringing
a band of thick cloud and some rain, nothing to
heavy south across Scotland and Northern Ireland
during the night, and that will trickle southwards during
the day on Wednesday, bringing a damp feel to much of
northwest England's parts of Wales and some rain trickling
into the Midlands for time as well.
Behind that weather front ten, much brighter, clearer
skies, some sunshine through the day, but also lower
temperatures, but still eight or nine Celsius.
There will be a brisk wind bringing plenty of showers in
across northern Scotland.
It could be quite a grey cold day across the south.
The rain will take most of the day before it arrives
and even then it won't amount of very much, but it will make
for a grey and cold day, five or six Celsius at best.
That weather front will be scooting away as we go
through Wednesday night and into Thursday.
Behind it, we do have the winds coming in from the north,
but if we take a look at the bigger picture, you can see
that the high has now shifted out to the west.
And actually those winds aren't coming down from the Arctic.
They're coming right around this area of high pressure.
So they're still being influenced by the Atlantic.
So it's not bitterly cold air that's coming in and that's
why temperatures will be on a more even keel
come the end of the week.
That's northerly winds will bring probably quite a bit of
cloud and some showers in that northerly winds just grazing
western most and the easternmost fringes.
But most places will be dry.
Quite a bit of cloud, but some brightness and temperatures
in single figures. If it stays cloudy, it'll probably feel
pretty cold through much of the day, particularly exposed to
that breeze on the North Sea coast.
But the high is still with us through Friday.
Whether it's just toppling around the top of it, still
bringing some thicker cloud to northern Scotland and perhaps
a little bit of rain here.
But again, on Friday, most places dry as the high builds in.
The winds won't be quite as strong and
generally not quite from the north either.
So bringing again, that milder air back into the west,
temperatures in the northwest could get to double figures,
but there will be some rain here.
Elsewhere, we're looking at six or seven degrees Celsius
for many on Friday. But again, a bit of sunshine will make
all the difference. That high pressure isn't moving very
far. It's likely to stick around into the weekend, but
all the while staying out west.
So allowing weather fronts to topple around the top of it,
but still keeping much of the country dry as we head
into the weekend.
That's it for your week ahead outlook.
