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.
