Planning Outlook All mountain areas of Britain from Thursday, 23 January, 2020 High pressure will slip away southwards toward the weekend, allowing low pressure over the Atlantic to the northwest of Britain to dominate again. A series of increasingly active frontal systems will move across Britain. Frequent and sustained upland gales by the weekend onward into next week. Stormy some days. Temperatures will vary; some marked cycles of freeze and thaw, but more frequently cold, with freezing levels sometimes down to 600m or below, and clusters of snow or hail showers coming in on a cold westerly flow on several days next week.
