Scientists say climate changes means periods of more intense rainfall can be expected.
Figures from the Met Office, external suggest that 1.5C of warming could bring up to 16% more winter rainfall to Aberdeen and 13% more in Aberdeenshire, compared with levels in the 1980s and 90s.
Lead weather presenter Helen Willetts said: “It’s been so wet and grey for many parts of the UK.
“However, finally on Thursday, Aberdeen recorded 30 minutes of sunshine officially bringing its sunless spell to an end.
“Surrounding areas in north-east Scotland might well have seen a smidge of blue sky on Thursday too, but Friday is the day when the cycle will be properly broken and the sunshine will return more widely.”
BBC Scotland weather presenter Judith Ralston said: “With a change in weather type, we finally lose the stuck pattern of cloud, rain, and bitingly cold winds.
“This finally breaks, allowing a northerly air mass to set in, bringing much drier, brighter conditions, sunshine on the way on Friday and Saturday and a few wintry showers on Friday.”
