Fronts will sweep northwards, associated with low pressure centred to the southwest. A spell of heavy rainfall for many places, with a risk of local thunder. The most persistent falls transferring into Scotland through the day, whilst a rash of heavy showers will move across England & Wales from the southwest. Blustery winds, risk gusting gale force around exposed southwestern coasts. Highs 17 to 23C.
Low pressure centred toward the north brings periods of heavy rain to north and western regions. Showery for many places, whilst east & southeast England may escape more often dry. Windy across southern counties, gales around coasts and headlands. Temperatures up to 23C in the southeast, nearer 17 to 21C for most, cooler where rain persists.
Low pressure pulls away slowly toward the northeast but leaves a legacy of showers or some longer spells of rain for northern Britain and Ireland. Brighter with sunny spells and passing showers in the south. Blustery winds, although easing compared to previous days. Cool in the north, fairly warm in the south. Highs 15 to 23C.
Detail is uncertain. For many places, a bright day with scattered showers. Some indications see an area of low pressure forming around Biscay and skirting across southeast England, with a spell of heavy rain and strong winds. A risk that this rain may extend more widely across England. Highs 15 to 22C.
A general westerly airflow is likely. Rather cool temperatures with sunshine and showers. Rain may be more frequent in the west. The south and southeast may escape more often dry. Highs 14 to 21C.
The next series of Atlantic fronts are never too far away. A risk of persistent rain returning from the west or southwest. Brighter for a time ahead of this, for longest in the east. Highs 14 to 22C.
