A few fog patches could linger in the glens this morning, but the hills and mountains will have some long spells of sunshine, this lasting longest across the Cairngorms the Aberdeenshire and Angus Hills, though turning hazy at times due to high cloud. Later in the afternoon, lower cloud will return to the Ben Alder, Breadalbane and Ben Lawers areas bringing some hill fog, and perhaps a few patches of drizzle or snow grains. These cloudier conditions will then extend into the Monadliaths, Cairngorms, Lochnagar and Angus Hills this evening.

Freezing level variable, mainly below 600m though summit temperatures could still be a few degrees above zero in the sunshine above the inversion.
