Marine Weather and Tide Forecast for Cameron Park, CA

DISCUSSION

Today Through Mid Next Week
Current GOES-West visible satellite imagery illustrates the dense fog from this morning lifting and burning off this afternoon. The Dense Fog Advisory has expired as visibilities have improved significantly across the area. The region remains under upper level ridging, with dry and mild weather prevailing for much of interior northern California. This inversion pattern is bringing daily chances for fog and low clouds in the Valley and lower foothills, especially from Marysville southward. High resolution guidance shows a 50 to 70 percent chance of visibilities less than 1/2 mile once again tonight into Sunday morning. The fog and low clouds will delay some of the daytime heating in those lower elevations beneath the fog. Elsewhere, above normal temperatures are forecast, along with periodically breezy offshore flow. The warmer temperatures and offshore flow will keep humidity fairly dry for higher terrain. This pattern will continue this weekend through mid next week.

Late Next Week
Ensemble guidance and cluster analysis indicate the flattening of the upper level ridge late next week, with the potential for a weak system to bring very light precipitation, with a 25 to 50 percent chance of 0.01" across interior NorCal. Latest guidance from WPC brings in just a few hundredths over a small area in the mountains for QPF. A cooling trend in temperatures is expected as well, with forecast highs in the 50s to around 60 for the Valley.
The Climate Prediction Center is then indicating that above normal temperatures and above normal precipitation chances are favored for northern California in the 8 to 14 Day Outlook which covers the January 25th through 31st timeframe.
