All right, another forecast! I’ve been to the Napa area within the last year, and I do have to say, it is significantly more beautiful than I anticipated, but also much different. That said, I didn’t quite know what to expect.
At 754PM, PT, Napa was reporting a temperature of 64 degrees with clear skies. Fog and low clouds were settling into the South Bay as night encroached, and the clear skies and dewpoints in the mid 50s suggest that fog will be likely in the Napa Valley as well, particularly given that it is only approaching 8pm.
A trough moving through the Pacific Northwest is churning things up further to the north along the Pacific Coast, while high pressure hasn’t yet settled into the southwest to provide the offshore winds to battle back the marine layer. Napa looks like it will warm up a bit as the weekend arrives, which may limit the morning and evening haze on Friday.
