Headline:

Some patchy rain for today, but also some escaping dry.

Today:

Rather cloudy with some patchy light rain about, but many dry from a line Inverness to Cape Wrath northwards with some brighter spells developing to bring seasonally mild afternoon highs here. Southerly winds strengthening across far west for afternoon. Maximum temperature 18 °C.

Tonight:

Thickening cloud bringing rain, which turns persistent and heavy in the west, particularly across the southern end of the Great Glen. South to southwest winds strong across coasts and Isles. Minimum temperature 11 °C.

Wednesday:

Cloudy with rain, this generally patchy towards Inverness, but turning more organised in west with heavier outbreaks focused around the southern end of the Great Glen. Brisk southerly winds. Maximum temperature 18 °C.

Outlook for Thursday to Saturday:

Very wet and windy with worst of the conditions in the west. Best of the shelter expected towards Inverness.

This period could begin with some very disturbed weather for the British Isles, with a deep low probably passing to the north or northwest of the country. This means there is potential for very strong winds and some further heavy rain, especially, but exclusively for more northern areas. Into the following week, a broadly westerly type looks most likely, with further weather systems running in from the Atlantic. On balance, southern areas stand a better chance of seeing longer drier interludes. However, confidence in the details remains on the low side, owing to ongoing Atlantic tropical cyclone activity. Overall, temperatures probably fairly close to average by day and whilst some overnight frost cannot be ruled out, especially later in the period, nothing overly cold is signalled at this stage.

A continuation of the broad patterns from the end of the 6-15 day forecast is anticipated at first, with the more unsettled conditions focussed towards northern areas and the best of the drier interludes further south, bringing the potential for some overnight frost and fog here. With time, there is a signal for more widely unsettled weather to develop, with more frequent bouts of wet and windy weather affecting a greater portion of the UK. Given the likelihood of westerly winds predominating, temperatures should average out a little above the seasonal norm, with overnight temperatures more often relatively mild, and with a reduced incidence of overnight fog, compared to normal.
