Planning Outlook
Largely dry weather continues this week as high pressure stays nearby. Very dry ground and high fire risk, beware of some ongoing fire management with locally restricted access to hills. A prevailing northwesterly wind brings further low cloud and some drizzle onto northwestern Scottish mountains - more widely across the western Highlands later in the week as the flow turns more westerly, with occasional steadier light rain. Patchy cloud over tops elsewhere, best sunshine and warmth in east and south-facing areas. Westerly winds strengthen everywhere into the weekend, bringing some rain and showers to all regions. A changeable and cooler outlook is expected into the last week of July.
