Unsettled onward into early next week, as slack low pressure drifts slowly over the British Isles. Slow-moving showers and areas of persistent heavier rain in places, increasingly thundery downpours, these most extensive over England and Wales by Sunday. Staying fairly warm, quite humid. Often low wind speeds, but gusty south-southeasterlies at times. By mid-next week onward into late July, west to southwesterlies likely to prevail, with some rain or drizzle at times mostly western Scotland, often dry further south and east.
