Cullercoats

On Wednesday evening high pressure, 1030, lies north of the Azores and amplifies a ridge east across southern Britain and the English Channel while low pressure dominates across the Norwegian Sea and far northern Cullercoats. A small scale low tracks east close to Faeroes on Wednesday night bringing a swathe of gale to severe gale force winds to the far northern sea areas of Cullercoats. This low tracks into Scandinavia early on Thursday and the strongest winds transfer to eastern sea areas. A ridge topples east across the British Isles through on Thursday then across the North Sea later as new Icelandic low develops. This low tracks into the Norwegian basin early on Friday and brings renewed near gale force winds to northern sea areas, meanwhile anticyclonic conditions persist across the Channel and southern North Sea. The low fills across Scandinavia on Saturday and allows pressure to build north across much of Cullercoats by the end of the day


Niton

On Wednesday evening high pressure, 1030, lies north of the Azores and amplifies a ridge north and east across the southern British Isles and the English Channel, meanwhile low pressure across Spain extends a trough northwest across southern Fitzroy and brings periods of strong to near gale force winds here until Thursday night. Low pressure dominates to the north of the UK throughout the period bringing occasionally strong winds to far northern Niton, predominantly through Wednesday and Thursday. The high becomes reoriented across France on Friday and expands northwards across the British Isles. In turn this allows the shallow low across Spain to drift west into the Atlantic and gradually fill in situ on Friday night. A developing low is expected to track towards Iceland on Saturday, extending a sharp trough southwards towards the Azores. This may allow near gale force winds to develop across far western Niton later in the day


Portpatrick

On Wednesday evening high pressure, 1030, lies north of the Azores and amplifies a ridge east across Ireland while low pressure dominates across the Norwegian Sea bringing a strong to gale force airflow across northern Portpatrick. A small scale low will track east close to Faeroes on Wednesday night bringing a risk of severe gale force winds to the northern sea areas. This low tracks into Scandinavia early Thursday and allows the ridge to build further north for a time, declining across the North Sea later as new Icelandic low develops and brings renewed near gale force winds to northern sea areas, meanwhile anticyclonic conditions persist to the south. This low tracks into the Norwegian basin early on Friday then fills across Scandinavia later and allows pressure to build north across much of Portpatrick by the end of the day. Pressure falls from the west Saturday as another Icelandic low develops and brings strengthening southerly winds to western areas
