Planning Outlook
By Thursday, west to southwesterly winds increase for Scotland, with frequent showery rain and low cloud returning into the Highlands from the west. Friday brings heavier rain to western Scotland and gales over higher terrain for Scotland and possibly northern England, rain extending further south with time. The weekend looks unsettled with low pressure bringing heavy showery rain widely, risk isolated thunder. Next week maintains a mixed westerly regime with greatest risk of rain toward northwest Scotland, drier and warmer further south and east.
