Should see more sun than cloud as the day progresses and the freezing level will spike to above 3000 meters today with daytime heating. The ridge will strengthen for the weekend with mostly sunny skies into Monday. The exception being a weak shortwave trough pushing through on Friday night into early Saturday morning with a few showers but the ridge rebounds with sunny skies after 06:00 Hrs. Guesstimates; trace-2 mm by Saturday morning. A mix of sun and cloud next week, possibly some precipitation again next Saturday.
