If you're in eastern parts today, you're into the last chance saloon of our settled spell of weather, with western and northern regions already past that point, and set to see some rain moving in during the day.

The change is all happening because the Atlantic has woken up after a bit of a slumber, with the jet stream firing a selection of low pressure systems our way during the remainder of this week. Today sees the first of those approaching the north of Scotland, and it's the weather fronts associated with that which are going to be moving west to east through the day and overnight to eventually bring some rain through to all parts.

Some of the rain will be on the heavy side, particularly in the west but just about anywhere could catch a heavy burst as it moves through. Timings wise, the rain crosses Ireland and gets into the far north of Scotland this morning, then pushing further east so much of the northern half of Scotland turns wet into mid-afternoon, with Wales, and other western parts getting in on the act by late afternoon or early evening, with the rest of the country seeing the rain through the evening or overnight. Behind the more persistent rain, sharp, thundery showers will spread through from the west.



Temperatures today will be warmest in central and eastern regions, reaching 17-20c. Cooler in the west with the cloud and rain arriving, and also cooler on the south coast with a fresh onshore breeze.

The rain continues to move through overnight, as do the showers following it, and that's where we're at tomorrow. By this time, we'll have a fairly slack low pressure right over the top of the UK, which is going to bring a showery, thundery day with some really sharp downpours and thunderstorms likely to develop. Between the showers there ought to be some brighter, sunnier spells though with highs generally up into the low-mid teens.
