As a result of showers overnight, some fog is possible in the early morning until sunrise on Friday. Overcast conditions are likely to start the day, but as the day progresses expect much of the cloud cover to break up. With little motion at the surface and lower levels, look for light winds out of the north and northwest.
For Saturday, a low pressure system will move towards Ireland and the United Kingdom from the North Atlantic Ocean during the morning hours. An upper level shortwave trough located over the surface low will help contribute to some slightly stronger winds at the surface during the day. However, as the day progresses, the shortwave trough will propagate east and winds in the upper level will shift towards the north. The surface low will likely weaken as it moves over the British Isles and as a result wind speed will likely weaken as well. With the combination of upper levels winds from the north to northwest, and lighter winds at the surface and lower levels, look for mostly cloudy skies for the majority of the day. Similar conditions are expected on Sunday, as upper level winds are likely to weaken from the shortwave trough continuing its track eastward.
