Southerly 15mph, likely strengthening through day to 25-30mph, risk reaching 40mph by evening or night.
Starting small, but becoming increasingly blustery, risk deteriorating to give arduous conditions later.
Occasional rain
Pulses of rain drifting northeastwards, risk fairly persistent over a few hours west Wales, otherwise may be patchy in nature, but the odd heavy burst possible.
Fairly persistent western summits
Lowest and most persistent cloud focused on coastal mountains, at times may form to lower slopes around Llyn Peninsula. Likely to linger all day on higher tops, but north and east from the A5 some breaks above 800m.
20% near coast, 60% toward north/east.
Mostly cloudy, often murky west Wales, but brighter toward east where visibility good below cloud.
8 to 10C

A relatively quiet start to the week, but expect local showers or patchy rain. Lowering pressure Wednesday into Thursday then leads to an unsettled end to the week. Widespread rain and heavy showers, some thundery downpours. The most sustained rain likely focused on England & Wales. Windier too, the strongest winds expected across southern Britain, where gales are possible at times Thursday-Friday. A little warmer through midweek, but no imminent return to hot weather. Likely staying generally unsettled through the weekend as low pressure continues to influence Britain.
