Key Messages

- Nearly perfect weather with highs 75-80F and lows 45-50F.

A strong upper level ridge will effectively block all perturbatory flow impediments to our close to perfection 7-day weather forecast. It will keep us pleasantly dry with daily highs in the mid-upper 70s and lows in the mid-upper 40s; a few outlier 80-81F and 50-51F readings are possible.
Patchy daybreak fog cannot be completely ruled out any morning but it should be shallow/brief and burn off quickly if/where it occurs.
Enjoy the dry weather run while we can as it appears we transition to an above normal pcpn pattern in the 6-10/8-14 day outlooks.
