Summary
The Olympics are here, but so are the showers
High pressure dominated the weather last week. The jet stream finally pushed north and many of us had the summer sunshine we had been hoping for. It was dry and sunny for many and very warm, especially in the south. We had the highest temperature of the year so far - 30.7C at St James's Park.
We kept a close eye on Friday's weather, with the headache of showers in the London areas and a small risk of rain at the Olympic Park for the opening ceremony. In the build up there was a small shower but the ceremony was thankfully dry.
This week high pressure will push back south allowing frontal systems to move across the UK.
Monday 30 July—Sunday 5 August
Low pressure returns with cooler, wetter weather
It will be a cool end to the month as frontal systems bring wet weather back to most areas.
Generally it will be an unsettled start to the week with sunshine and showers. During the middle of the week, low pressure will approach from the west bringing cloudy skies and outbreaks of rain to all. Rain will be heavy in the west with gusty winds.
The low pressure will sit to the west for the end of the week bringing a mix of sunny spells and showers to all areas, possibly merging into persistent rain across the north and west. The best of any sunny spells will be in the east. It will be windy at times with temperatures close to or just below average, especially in any rain.
Monday 6 August—Sunday 12 August
Still sunshine and showers
High pressure will linger close to the south and lower pressure will sit close to the north. The remainder of the period will see further sunshine and showers, again merging into longer spells of rain in places, particularly towards the far north.
It will continue to be rather cool but temperatures may recover in any sunnier spells towards the south and east. By the end of the period, some longer spells of drier weather may develop across southern parts with temperatures recovering closer to average.
Monday 13 August—Sunday 26 August
No heat wave
A lengthy spell of hot, sunny weather across the whole country currently looks unlikely towards the end of August. It is most likely that the weather will remain changeable with southern areas having the best of any dry, bright and at times warm weather. Some rain is likely in places, which may be heavy at times, most likely further north.
