most part with a high of 21 or 22. Into the start of the new week,

changeable weather Into the start of the new week,

changeable weather to say the least. Good evening, mixed, unsettled,

changeable, many words you could use to describe the weather we've had in

the last week but heatwave would not be one of them. That is a far cry

from the weather we have been seeing across southern Europe. Today was

another day of dangerous heat in places from the Balkans westwards

towards southern Spain, temperatures well up into the 40s, close to 45

degrees in parts of southern Spain, a lot of this down to the jet

stream, southern Europe is on the southern side of the jet stream and

we are on the northern side of it, the cold side of the jet stream. It

is the jet stream, the winds high in the atmosphere, that pushes the

weather systems around the globe. And you can see we have a queue of

them waiting in the wings to moving over the next few days. The weekend

essentially stays pretty changeable with a mixture of sunshine and heavy

showers and generally a rather cool feel to the weather. Back to the

here and now, this evening and tonight, Central and eastern areas

largely dry with a passing shower, more showers in Northern Ireland and

Scotland, which will drift into Wales and the south-west and

temperatures of 9-15. Tomorrow is a day of sunshine and showers but

particularly in the morning across Wales at the south-west and then

later through the Midlands, East Anglia and eventually the

south-east, we will see some really heavy showers drifting through with

hail and thunder. It could give a lot of rain in a short space of

time. Further north, not as many showers but there could still be the

odd hefty downpour later in the day, the showers should ease away to some

extent for Northern Ireland and north-west Scotland but temperatures

disappointing for August, 16-21. As the World Championship athletics

continues in London, there could well be heavy, Bunbury showers in

the afternoon but the risk of a shower decreases as we go into the

evening. That is the story for just about all of us. Things become

largely dry with clear spells and a ridge of high pressure building, and

with light winds, and unusually cold night for August, surprisingly cold

I suspect if you live in the countryside, look at the

temperatures, maybe two degrees in the sheltered glens of Scotland,

otherwise single digits and even a touch of grass frost in places.

After a cool start, a dry day for many on Sunday, particularly central

and eastern areas, more cloudy to the West with rain splashing

sporadically in later in the day and temperatures 15-22.
