Marine Weather and Tide Forecast for Clarksburg, CA

DISCUSSION

Today into Tuesday
An upper level trough moving through the PacNW will continue to bring area of clouds and a few light radar returns across the area. Nothing measurable so far in the area and this will likely continue to mainly be the case as the system skirts the area to the north. A few light accumulations possible across northern mountains but otherwise only tangible affect will be increasing onshore flow and some clouds with cooler temps.

Wednesday through Sunday
As early-week trough shifts into the Great Basin, we'll see winds shift out of the north and increase on Wednesday into Thursday.
As north winds increase, conditions will dry out with daytime relative humidity dropping into the single digits to teens across the Sacramento Valley with limited overnight recovery. Ensemble guidance and EFI in good agreement with highest threat across the typical western side of the Sac Valley. With increasing confidence in critical fire weather conditions, we've upgraded the current Fire Weather Watch to a Red Flag Warning. We did trim off the southern end (Delta to Sac Metro) as it looks like limited duration of red flag level winds.

In tandem with critical fire weather conditions, temperatures will begin to heat up as strong upper level riding builds along the West Coast. By Thursday, widespread triple digits are expected in the Valley with much above normal temperatures across higher elevations. Widespread moderate to locally major HeatRisk will bring about the potential need for heat headlines as we go further into the week. Temperatures will likely remain in the triple digits through about Saturday before slight cooling for the end of the weekend as ridging gradually flattens.

AVIATION
VFR conditions next 24 hours. Westerly winds with gusts 15 to 25 kts through 05-06z tonight invof Delta, southern Sac and northern San Joaquin Valleys. Lighter winds expected on Tuesday with clearing skies.
