Marine Weather and Tide Forecast for Clarksburg, CA

DISCUSSION

...Today & Tuesday...
Mid-level clouds across foothills and mountains this morning, with some light returns noted on radar. Some accumulating rain showers and high elevations snow showers were observed overnight/early this morning as well as an upper level low north of the region influences the weather pattern over our area. Temperatures are fall-like this morning as well, with mid to upper 50s/low 60s across much of interior NorCal. Locally gusty north winds in the northern Sacramento Valley will continue today as well, as the low pressure continues to have a north to south pressure gradient over the Valley. For the rest of Monday, isolated mountain showers, high elevations snow showers (little to no additional accumulations), and a few isolated rumbles of thunder will be possible, but those chances are decreasing as we move through the rest of the morning.

Tuesday we will continue to see more fall-like high temperatures across interior NorCal. Low pressure will begin to dig south into Nevada Tuesday as well, shifting the stronger north winds to the south and west into the Delta and Coast Range. Increased drying on the backside of the low pressure along with the breezier northerly winds will create elevated fire weather conditions in the northern Sacramento Valley and mountains Tuesday, with wind gusts of 20 to 30 mph and daytime humidity values in the teens to low 20s. Low pressure translates further east as we move through the rest of Tuesday.

...Wednesday-Saturday...
By Wednesday, ensembles remain in good agreement that high pressure will begin to build in the Pacific. Warming trend, with drying conditions will remain in the forecast as we move through the work week. Pattern will once again result in breezy north to east winds across the region, ushering in the potential for elevated fire weather conditions for most of the region Thursday and Friday. Strongest winds look to be in the mountains, where downslope gusts of 25 to 45 mph are in the forecast now.
Uncertainty remains in exactly how strong downslope winds will be, along with how low humidity values will be later this week.
Temperatures will bounce back into the mid to upper 80s/90s by Wednesday and continue through at least Saturday. Long range ensembles showing the potential breakdown of the ridge by late weekend, early next week, which would at least usher in more fall- like high temperatures to the area.
