It's lovely in mid-Devon at the moment, with clear pale blue skies (8.6°C) but by the look of it, it won't stay that way for much longer. If you look at the animation on the 15 minute visible satellite images from the Met Office, the cloud edge of the low stratus that's currently across Wiltshire and approaching Dorset must be moving W'SW at around 15 knots at a guess, and will reach here in a couple of hours or so. Hopefully in that time insolation should have lifted the base a bit and fragmented it a bit - who am I kidding.

Of course according to the Met Office this is a warm front albeit weakening (see their 06 UTC analysis) but without the thickening layers of cirrostratus and altostratus ahead of it, more a boundary level feature. To be quite honest looking at the 09 UTC SYNOPs I can't see any real change in dewpoints across the whole country.
