Wednesday then looks like a dry day on the whole, with fog lifting by mid-morning.
There could be a few showers across Wiltshire around late morning, and there generally won't be as much sunshine around.
Temperatures will reach 13 to 14 Celsius.
A few showers are likely on Thursday, followed by the change to a spell of wetter and winder weather on Friday which will last into Saturday.
Temperatures should be a touch higher by the weekend at least.
