Planning Outlook
Powerful southeasterlies prevail across Scotland this week and many indications favour strong east or southeasterly winds onward into the first half of February. Scottish mountains are expected stay below freezing in the extended range, fresh heavy snowfalls giving substantial depths and drifts across south and eastern areas, much less snow northwestward. Hills in England and Wales will see varying freezing levels, sub-zero for periods to 600m or lower, but intermittently lifting just above the tops - a mix of rain and upland snowfall. A generally unsettled pattern with Atlantic lows continuing to frequently circulate over Britain on a southerly track, whilst high pressure resides away to the north.
