Marine Weather and Tide Forecast for Cloverdale, CA

DISCUSSION

...Today-Friday...
Strong high pressure continues to dominate the synoptic pattern this week, resulting in record-breaking heat across much of the area. Yesterday, Sacramento, Modesto, and Stockton recorded/tied their all-time hottest March day on record; and Modesto AP recorded it's earliest 90 degree day on record. Today and Friday will see the hottest temperatures of the week, with widespread Minor HeatRisk and areas of Moderate HeatRisk. The NBM is currently forecasting a 70-90% chance of highs 90 or greater throughout the Valley and Delta today & Friday. If Stockton AP or Sacramento hits 90 degrees today, it will be the earliest 90 degree day on record at those two sites.

...Saturday-Wednesday...
Temperatures cool down slightly over the weekend, as ridging flattens out and shifts eastward over the Great Basin.
Temperatures will still be several degrees above-normal, but are forecast to be slightly cooler than previous days. Minor HeatRisk will still be widespread especially in the Valley and Delta, but some areas in the mountains will fall below any HeatRisk concerns.

There is still a degree of uncertainty regarding the eastward trajectory of the high, which could allow a weak lobe of energy to bring very light showers over the Shasta County mountains mid next week. However, probabilities for 0.1" or more are currently less than 25%. The majority of ensembles favor the redevelopment of high pressure and rising heights mid next week, which would yield continued dry weather and above-normal temperatures.

If you are outside or planning outdoor activities this week and over the weekend, please remember to drink plenty of water and wear sunscreen. As this is an anomalous heat event, individuals may not be fully acclimated to the emerging heat. Local waterways are also running very cold due to snowmelt.
