Planning Outlook

High pressure brings settled weather and lots of spring sunshine through midweek, warm days with high UV; cool nights with grass frost in sheltered spots. Strong and gusty easterly winds will prevail for England, Wales and southern Scotland, whilst southeasterlies also tend to increase further across the Highlands by Thursday. Very dry grass and moorland conditions over mountain terrain continues to present a very high fire risk. A shift toward lower pressure by the end of the week brings a likelihood of showers on Friday, locally heavy. Southwesterly winds are then likely into the Bank Holiday weekend - cooler with a mix of sunny spells and showers in the extended forecast; very highest Scottish summits may dip close to freezing point.
