..Wednesday through Weekend
As the ridge pulls eastward, we will see cooling on Wednesday returning highs to the 80s and Minor HeatRisk across the Valley. Ensembles continue to trend drier for the trough passage with most locations now remaining dry outside of slight shower chances over Shasta County. Overall, expecting little to no impacts from precipitation over the next several days.
Concerns for gusty northerly winds are increasing for the weekend as ensembles are starting to lean more towards an inside-slider type shortwave shifting into the Great Basin. Today's models trended slightly weaker for Saturday but stronger on Sunday in regards to wind strength but similar affected areas. Current forecast have north winds gusts of 30 to 45 MPH this weekend, strongest on Sunday and along Interstate 5.
Additionally, dry conditions develop particularly over the Sacramento Valley, especially north of Interstate 80, with the NBM showing minimum Relative Humidity getting into the teens and upper single digits. Ultimately, this brings elevated fire weather concerns for the Valley and portions of the Delta and will continue to monitor model trends to evaluate strength of winds/drying effect over the Valley.
