Planning Outlook

Much warmer and feeling humid as winds shift southerly through Wednesday. Low pressure to the west and a front pushing in brings a risk of thunderstorms on Thursday, soonest in Wales, advancing northeastwards over England and Scotland likely afternoon into evening - some uncertainty of timing. Low pressure is likely to linger later week into weekend - initially staying warm and humid, bringing an ongoing risk of thundery downpours, mixed with sunnier spells. Likely cooler and windier with time over the weekend. Southwesterlies then prevailing with rain at times, most over western mountains into early next week, but a trend toward higher pressure building from the south with drier conditions emerging.
