This period will start with cloud, rain and strong winds affecting northern and western parts of the UK on Monday. The cloud and rain is expected to ease and clear to the southeast during Tuesday as high pressure builds in from the west. There is now a signal for high pressure to be largely dominant through the rest of this period. This will mean many places seeing plenty of dry weather with variable cloud amounts and some sunshine, but perhaps with some fog overnight. Frontal systems may still graze the north and west of the UK at times though, maybe also briefly affecting other parts. Temperatures will be near or above normal, although patchy overnight frost is still likely at times.

After a potentially mainly dry and settled start to this period, changeable conditions look likely to resume, with Atlantic frontal systems spreading across the UK at times. These will bring spells of rain and perhaps strong winds, with the wettest conditions likely to be in the northwest, whilst the southeast will likely be driest. Temperatures are likely to be near to or slightly above normal overall. It is possible that longer spells of dry weather develop again later in the month as a more blocked pattern could develop, which could lead to some colder conditions too, but confidence is very low by this stage.
