Planning Outlook
Staying very warm late weekend into next week. High pressure north of the country keeps the skies mostly clear and facilitates an an easterly flow, pushing the warmest temperatures to western hill groups. Northeastern areas will see early sea fog under the high pressure, this dissipating in the sun through morning. Scottish highlands seeing temperatures often rise into the mid-teens, valley temperatures to the 20s west; warmest Wales where hill temperatures often to 20C or higher. A fairly sustained breeze most of the week in England and Wales, at times stronger and quite gusty. Low pressure south of the country may push cloud and showers into Wales, though confidence remains low, and could remain largely dry. Detail uncertain later next week, but a milder northerly flow may begin to establish.
