KEY MESSAGES

- A Red Flag Warning is currently in effect for the Valley and Delta below 1000 feet, and continues until 8 PM Monday.

- Critical fire weather concerns for the Valley & Delta, with gusty north winds and low humidity. Strongest winds through tonight along and west of the I-5 corridor.

- Above-normal temperatures continue through the forecast period with Minor to Moderate HeatRisk.

..Tuesday to Saturday

A warming trend continues on Tuesday and through the late week, with increasing areal coverage of Moderate HeatRisk in the Valley and foothills. Thursday also sees 70 to 90% chance of triple digit temperatures, primarily in the central and southern Sacramento Valley east of I-5. Daytime relative humidities will also remain in the single digit to teen range through at least the end of the week. This means that even with light winds in the forecast for the remainder of the week, some elevated fire weather risk will remain. It therefore remains important to practice fire safety this week! There is some indication that ridging will flatten out and therefore that temperatures will cool slightly over the weekend, but there is still some uncertainty in the forecast. Make sure to stay up to date at weather.gov/sacramento.
