KEY MESSAGES
- Heat Advisory in effect from 11 AM Saturday - 10 PM Wednesday the Sacramento Valley, Delta, northern San Joaquin Valley, and adjacent foothills.
- High temperatures, 10-20 degrees above normal, will lead to widespread Moderate HeatRisk in the Delta, Valley, and foothills Today-Thursday, with areas of Major HeatRisk in the Delta.
..Thursday and beyond
Extended guidance keeps us under broad ridging through the end of next week, with some slight uncertainty if mid to upper 90s will continue into next weekend. Cluster analysis reveals overall agreement in at least upper level ridging remaining in the region, however the strength and a slight shift to zonal heights aloft appear in some cluster members. Regardless, we expect at least slightly above normal to above normal high temperatures to continue through at least Thursday of next week.
AVIATION
VFR conditions continue through the TAF period for Interior Northern California. Light and variable winds through the period, with a few gusts to 15 kts within the Delta this evening. Otherwise, we will see a SCT to BKN cloud deck shift through the region through the TAF period.
