Planning Outlook
Westerly weather patterns prevail into the new week bringing generally unsettled and cooler conditions - single-figure temperatures typical on the Munros and high tops elsewhere. On Monday, extensive rain spreads across Scotland, heaviest in the west. Winds strengthen, risk reaching gale force on many hills later on Monday, staying blustery widely into midweek. Rain extends south over England and Wales by Monday night into early Tuesday. The rest of the week likely sees showery rain common for all areas as low pressure dominates toward the north, the rain most persistent in western Scotland, but odd heavier bursts passing eastward, with a chance of thunder, especially later in week.
