Cool temperatures are being observed across interior NorCal this morning, though temperatures are just slightly warmer than this time yesterday. Morning low temperatures are expected to once again fall below normal with the Valley and foothills ranging from the high 30s to low 40s and the mountains in the low 20s to low 40s.
Ensemble models are in good agreement of strong upper level ridging remaining in place over the Eastern Pacific and West Coast through Tuesday with a very weak low under the ridge lingering near SoCal. This will result in a continued slight warming trend through the weekend with temperatures leveling out through early next week. Above normal daytime temperatures expected with temperatures ranging from the mid 70s to low 80s in the Valley and 50s to upper 60s in the mountains. Humidities will slightly increase into early next week, though daytime minimum humidities will still be very dry. Light winds and no precipitation are expected under the current setup.
Extended Discussion (Wednesday through Saturday)
Dry and mild weather continues next week as the eastern Pacific ridge holds just off the West Coast keeping high temperatures around 10-15 degrees above average. Precipitation chances may return to far northern California by next weekend as ensemble means continue to indicate the ridge will flatten and shift east.
