KEY MESSAGES

- Increasingly hot and dry conditions through early next week, with widespread Moderate HeatRisk Monday and Tuesday.

- Hottest Days Monday and Tuesday with triple digit temperatures and daily record highs possible.

- Slight cooling trend from Wednesday onward, with increased delta breeze influence.

..Today through Thursday

A warming and drying trend continues today as ridging builds over the area and begins to progress eastward. Widespread Minor HeatRisk is expected today and through the weekend, with areas of Moderate HeatRisk in the Valley. High temperatures today are forecast to be in the 80s in the Valley, with weekend temperatures reaching the low to mid 90s. Lingering troughing influence will somewhat temper daytime highs and provide overnight relief through Sunday. This may also lead to some marine stratus intrusion in the mornings, especially on Saturday.

Early next week, 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). Due to the potential impacts of both the high temperatures and warmer overnight lows in these locations, we have issued a Heat Advisory 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.
