Marine Weather and Tide Forecast for Penn Valley, CA

DISCUSSION

Today
Stratus/Low clouds continued today across the Central Valley and lower foothills with heights below 1000 feet. As of 12 PM this afternoon, height have begun to rise although still present across swaths of the Valley and will continue through the evening before reforming and repeating tomorrow morning.

Dry weather and seasonable temperatures are forecasted for the region, with upper 40s to around 60 in the Valley and foothills, and 40s to 50s in the mountains for the daytime highs. Highs are trending several degrees cooler than initially forecasted due to the persistence of the fog/low clouds, keeping max temperatures from being fully actualized again.

Next Week
High pressure builds across the region next week, allowing for a gradual warming trend with high temperatures warming to the 50s to near 70 (mainly for areas outside of stratus/fog development). Dry conditions will continue through next week.
Current forecasts show very low chances (5-15%) for light showers across Shasta County on Tuesday but little to no impacts expected even if precipitation occurs. In the extended, models show chances for the ridge to weaken next weekend but still too far out in the future for any definitive forecast updates.

AVIATION
Lingering low cigs and mist across the Central Valley continue into this evening with IFR/LIFR conditions, although some sites may very briefly see MVFR/VFR visibility around 22-24Z, mainly for TAF sites north of Sacramento. Another round of BF/FG and low stratus returns once again tonight with areas of IFR/LIFR ceilings once again expected to persist through the day. Light and variable surface winds less than 12kts.

STO WATCHES/WARNINGS/ADVISORIES
