14 day UK: Vintage spell of summer?

Issued Sunday 20th July 2014

Week 1
Warm or hot weather is expected to continue for much of the country throughout the week.

Early in the week widespread sunny periods will develop with fewer showers around than recently. Temperatures in the south approaching 28C (82F) on Monday and Tuesday, but in much of the north closer to 23C (73F). Possibly cloudier at times in Northern Ireland.

During the middle of the week it remains very warm across much of the UK and hot in the south. The exception possibly Northern Ireland where there could be some outbreaks of rain.

The very warm or hot weather continuing through the second half of the week with temperatures edging up even further, possibly exceeding 30C (86F) in the south. There is also likely to be an increasing risk of thunderstorms again.

Forecast confidence high.

Week 2
Hot conditions are expected to continue in southern and central regions during the first half of the week. Warm in the north too. Possibly becoming more unsettled in the west with an increasing risk of showery rain.

Rain thunderstorms could become to extend east with cooler and showery air returning to the west. There is a lot of uncertainty and in the south the emphasis perhaps remaining on fine conditions.

Forecast confidence is moderate through this period.

Overview
Early in the period high pressure is set to build across the UK. For much of the forecast period this should block the flow of Atlantic weather systems.

Through the second week the Atlantic may start in influence things over the UK more, but confidence on developments is low. The tendency for high pressure to build back over the UK may remain.
