While skies of Fife, Scotland, will turn out mostly cloudy on Thursday as the British Open tees off, any rainy weather should hold off until the evening.
What will follow, however, is bouts of rain and even a thundery shower overnight into Friday.
Under increasing cloud on Thursday, a high of 16 C will be reached at St. Andrews as east to south-east winds off the North Sea reach 12 to 25 km/h, even gusting 35 km/h in the afternoon.
Elsewhere in the United Kingdom, much of England will warm noticeably on Thursday with London registering a high of 26 C.
Rainy low pressure tracking northward near Ireland will trigger the outbreaks of rain and thundery showers late Thursday until Friday.
High pressure will build over the United Kingdom on Saturday and Sunday. Aside from the odd shower on Saturday, golfers at the Open will enjoy generally dry weather with bright to sunny intervals.
Much of Scotland, including Fife, could get a showery start to next week as another area of low pressure tracks west and north of the British Isles on Monday.
