Planning Outlook
Next week the UK is situated under a boundary between high and low pressure with a trend towards more settled conditions in the south, unsettled in the north. Northwest England and west Scotland could be rather wet with a southwesterly wind pushing cloud and spells of rain onto western hills. Several more organized frontal systems are likely to pass into eastern Scotland as well. Generally dry for the Pennines and Wales, though cloud and occasionally drizzly rain will impact western areas, notably Lakeland and Snowdonia. Sun breaks likely in England but short-lived. First indications of more widely unsettled weather into next weekend as a deeper area of low pressure passes north, though confidence remains low regarding timing and strength.
