The mid summer heat of yesterday is history as the boundary that’s been creeping south all week pushes into France today. The UK atmosphere is now back in one air mass once again.

Despite sunshine, highs will, for most, fail to reach 20C in areas that were 24-25C at 4pm yesterday.

The good news is however that despite the cool down, high pressure (cool source though) builds into the upcoming weekend anmd looks set to dominate next week. This means April could become one of the UK’s driest following a dry February and March.

It was this setup back in late winter, early spring 2012 that led me into thinking a warmer, drier summer was ahead. However be aware, these setups are often misleading as warming waters to our southwest brews trouble.

Interestingly, yesterday’s 25.1C at Frittenden, Kent was in fact the UK’s warmest April day since 2011.

Next week looks to see the core of a strong high (near 1040mb) position just north of the UK and that means a cooler flow, keeping temps pleasant but not particularly warm for late April. North Sea waters are at about their coolest of the year right now.

But clear skies, fairly light winds will make for little or no rain, highs of between 10-18C but by night, outwith towns and cities, don’t be surprised to see early morning frost.

Here’s the GFS surface through the next 7 days.
