Planning Outlook
Generally dry much of the week ahead in Scotland. Some variable cloud and fog early in the week. A gusty easterly wind for England & Wales and rain pushes into Wales on Tuesday, reaching the south Pennines with time, persisting into Wednesday in these areas, but very little extending further north. Into the second half of the week, a switch to a colder northerly flow will likely drop the freezing level to 800m increasingly widely for Thursday-Friday, plus frost on low ground. Some snow showers on northern Scottish mountains, but largely dry weather elsewhere. During next weekend, a shift to a less cold Atlantic influence - a changeable mix likely into the following week.
