Planning Outlook

Humid air moves in from the southwest on Thursday with drizzly rain and low cloud particularly in western regions. A mixed outlook, as slack low pressure drifts slowly over the British Isles, giving slow-moving showers and increasingly thundery downpours, these most extensive over England and Wales into the weekend. Staying fairly warm, quite humid. Often low wind speeds, but south-southeasterlies may increase at times. By next week, west to southwesterlies likely to prevail, with some rain or drizzle at times mostly western Scotland, often dry further south and east.
