Low pressure will be off eastern Scotland on Friday. A showery westerly flow follows from the west. More cloud and rain affect northern and eastern Scotland, some of it heavy at times. Elsewhere it is going to be a much brighter day with good sunny spells. Showers across western and southern areas, these heavy at times on western coasts, but scattered inland. Highs at a cool 8 to 12C.
A complex area of low pressure affects the country through Saturday. A weak ridge of high pressure builds to the west, ahead of a further low developing off southwest Ireland. This may bring some rain through central and eastern areas on Saturday morning, before this clears to the east. It will then be fairly cloud to the south with mist and a few bright spells. More northern areas should be drier and brighter with good spells of sunshine, although rain may affect the far north of Scotland. Highs at 8 to 11C.
An area of low pressure is likely to be over the south of the country on Sunday. This is going to be bringing cloud and rain with it, and some of the rain could be heavy. Further north the rain is less persistent. A cool day at 9 to 11C.
The evolution of the low is unclear at the present time. However, indications are that the low deepens as it moves to the southeast of the country. This is likely to bring a colder, northerly flow through all areas as a ridge of high pressure builds to the west. It will be a cold day with some rain at first in the east. More western areas will be much brighter with good spells of sunshine, and should be dry too. Highs at 9 to 12C.
Confidence is low in the forecast for Tuesday, although at the present time we expect high pressure to the to the northeast of the country. This brings an easterly flow and mainly dry weather to many areas, but the risk of some rain to the south. Highs around 9 to 13C.
The east to northeast flow persists across the country on Wednesday. There will be some showers in the east, drier to the west and brighter too with some sunny spells here. Highs around 8 to 12C.
