Super Soakers

You probably know the drill very well by now, with low pressure very close by the UK is in a very unstable air stream and that means a fair rash of showers and thunderstorms developing during the day - both on Saturday and Sunday.

Many of the showers will be on the heavy side with some torrential downpours possible along with the threat of storms bringing hail, frequent lightning and gusty winds. Because of the storm risk we do have a detailed storm forecast issued.

During today, just about anywhere is liable to catch a downpour, although the north of Scotland and the southeast corner of England may well be best placed to avoid the worst of the weather. This is obviously pretty good news for Super Saturday at the Olympics but even here there is the risk of a shower or two, especially up until the early afternoon.

Temperature today will typically range from 17-19c, with just the southeast and East Anglia likely to see the odd spot sneak into the low twenties. It's breezy too, so feeling a touch cooler than those values may suggest, and cooler still under any downpours.

Overnight tonight the bulk of the showers and storms will die back, but we need to watch to the south as there is the threat of some further thundery downpours and storms moving up from the channel. Into tomorrow, the south may well start the day with those downpours still about, these will move north and further showers will develop across other parts of the country making for a very similar day to today. Once more, after the risk of showers during the first half of the day, the Olympic venues should become drier and brighter into the afternoon and evening.

Obviously with all of these downpours around throughout the weekend there is the threat of some disruption with surface water and localised flooding, so please do take care if you're out and about.

Looking into next week, we start with the unsettled theme continuing but from midweek we're increasingly confident that things will settle down and warm up with a good deal of warm, sunny weather on offer. How long this lasts is uncertain though, with low pressure potentially arriving from the southwest to spoil the party during the weekend..
