Marine Weather and Tide Forecast for Rancho Tehama Reserve, CA

DISCUSSION

Today through Friday

A warming and drying trend continues today as ridging build eastward. Widespread Minor HeatRisk is expected today and Sunday, with areas of Moderate HeatRisk in the Valley. High temperatures today are forecast to be in the high 80s to mid 90s. Lingering troughing influence will somewhat temper daytime highs and provide overnight relief through Sunday.

On Monday and Tuesday, daytime temperatures will climb again, with widespread Moderate HeatRisk in the Valley both days. Valley highs have potential to both meet or exceed local records, as well as reach triple digits in some locations. The NBM has a 30 to 50% chance of 100 degrees or more in the northern San Joaquin Valley, as well as in the central Sacramento Valley (particularly in eastern Glenn and Colusa Counties, and Butte County). A Heat Advisory remains in place for these areas from 11am on Monday through 8pm on Tuesday. Areas closer to the Delta will see much better overnight relief on Monday and Tuesday, though daytime temperatures will still be quite hot. Be sure to practice heat safety! Drink plenty of fluids, stay in an air-conditioned room or in the shade during the heat of the day, and consider checking in on those more susceptible to heat.

Ensembles depict the ridge breaking down towards the middle of next week which will result in a gradual cooling trend from Wednesday onward, however temperatures will still be 5 to 15 degrees above normal through the end of next week.
