Planning Outlook
A changeable pattern continues this week with west-southwesterly winds prevailing, bringing a mix of rain and showers in from the Atlantic. A period of more persistent rain on Thursday. Pressure tends to rise from the south toward the weekend, bringing warmer air and drier conditions particularly England & Wales, although western mountains will remain often cloudy, some patchy rain remaining in west and northwest Scotland into the weekend. Into next week, a mixed southwesterly pattern remains possible, with some rain, drizzle and low cloud mostly in the west, but with higher pressure trying to expand northward, the week looks generally drier and warmer than the present time.
