Smoke and haze from wildfires will continue to impact portions of interior Northern California. Below normal high temperatures will persist through early next week, warming above normal Thursday into Friday.
Discussion
Upper low over the PacNW with associated troughing extending over CA. Synoptic feature progged to slowly move through Oregon today, weakening to trough as it moves into the Intermountain West tonight into Sunday. Result will be increased onshore flow today into Sunday with cooler temperatures.
Stronger wind will help with some smoke dispersal in the Sacramento Valley today, but will also result in increased potential for fire spread with existing wildfires.
Long wave troughing remains along the West Coast Monday into Wednesday keeping high temperatures below normal. Locally gusty wind possible at times, mainly in the Delta and over higher terrain in the afternoons into evenings.
Extended discussion (Wednesday through Saturday)
Ensembles indicate that gradual warming and drying is likely to continue during the second half of next week as the weak trough gradually gives way to ridging from the eastern Pacific.
Temperature will be close to average at mid-week, then warm to around 10 degrees above average by next weekend.
