  1. Niton

    Tuesday evening, a weak ridge of high pressure lies across much of southern Niton, with an area of low pressure 994 centred Bailey influencing more northern areas of Niton. Overnight and into Wednesday day, the high gradually declines into the continent, allowing pressure to drop slightly in the north and west, with a separate low situated 1005 at North 45 West 21 at midday Wednesday. This low moves quickly east across Fitzroy during Wednesday night, arriving at Breast Peninsula 1002 by midday Thursday with a weak col developing behind it across Sole and north Fitzroy. A broad trough out in the Atlantic will gradually progress into western Sole and Fitzroy overnight Thursday, then across other northern parts of Niton during Friday day, with a weak ridge of high pressure across the UK ahead of it. Strong winds for a time across Shannon Tuesday evening, then southern Fitzroy Wednesday night.

  2. Cullercoats

    On Tuesday evening, a slow-moving low 994 will be centred Bailey, with a trough extension running west-east through northern Cullercoats. Meanwhile, weak ridges of high pressure lies across Biscay and across the southern Norwegian Sea north and south of the low. Overnight, the trough moves north and the low centre moves south, with centre 999 Forth by midday Wednesday. Overnight Wednesday this low centre moves further east across Cullercoats and becomes centred 997 over South Utsire by midday Thursday, with a slack trough extending southwestwards through the English Channel to the Breast Peninsular. The low deepens and moves bodily eastwards across Sweden during Thursday night into Friday, allowing a weak ridge of high pressure to build across western areas of Cullercoats. Strong winds for a time across Dogger on Wednesday day, then again on Friday across South Utsire, Fisher and eastern German Bight.
