Patches of rain from overnight continue into the morning, the greatest risk in the east with odd heavier moments. May trend drier with time, most likely west.

Cloud on the hills?

Most extensive early, may improve

From dawn, cloud may be extensive above 600m, lower patches probable too. A chance of improvement from the west, bases lifting somewhat with higher breaks, though eastern areas may well stay shrouded.

Chance of cloud free summits?

30%

Sunshine and air clarity?

Largely overcast, some brighter moments to the west. Excellent visibility away from cloud/rain.

How Cold? (at 750m)

2C.

Freezing Level

May just touch the highest summits, frosts soon thawing after daybreak.

Planning Outlook

Thursday into Friday sees a band of rain pass east across most mountains, then a relatively settled weekend for England and Wales, and perhaps east Scotland too. Varying conditions over the next couple of weeks as areas of high pressure build across the British Isles then slip eastwards: dry and bright days with light winds mixed with periods of strengthening south/westerly winds bringing occasional rain from the west. Temperatures will vary, at times lifting just above freezing to high Munro tops, but typically lowering again to high terrain and briefly mid-slopes. Freezing levels will only briefly touch high England and Wales summits, but some frosts into valleys during clear-sky nights. Remaining old snow cover on Scottish mountains stays largely consolidated with little change, any remaining snow in England and Wales will thaw.
