Area Forecast Discussion National Weather Service Sacramento CA 211 PM PDT Fri Aug 7 2020

SYNOPSIS. Warming trend through the weekend, turning above normal by Saturday. Moderate heat risk for the northern Sacramento Valley and foothills Sunday and Monday. A slight chance of mountain thunderstorms from Friday into early next week.

DISCUSSION. Temperatures early this afternoon are around 4 to 10 degrees warmer than this time yesterday across the Valley, a couple degrees warmer in the mountains. The upper trough over CA continues to slowly separate from the main flow today as the main jet moves into Montana, allowing heights to raise and temperatures to warm for NorCal. Temperatures will peak right around normal today in the 90s to 100 in the Valley and 70s to upper 80s in the mountains. Models indicate just enough moisture streaming around the low and instability to produce a slight chance of isolated thunderstorms over the Sierra crest this afternoon and early evening, mainly south of I-80.

The upper low cuts off by tomorrow and will linger off the Central CA coast into early next week. Upper heights and therefore temperatures will continue to rise through the weekend, rising 2 to 5 degrees each day to 5 to 10 degrees above normal by Sunday and Monday. Moderate heat risk is forecast Sunday and Monday, especially in the northern Sacramento Valley and adjacent foothills, as Valley temperatures peak in the upper 90s to 108. Overnight lows will be fairly warm in the north as well, only falling to the upper 60s to low 70s through Monday night. Sensitive groups should take precautions to protect themselves from this heat, especially those without air conditioning or those with outdoor plans.

The cut off low lingering off the coast will continue to produce a slight chance of afternoon and evening thunderstorms over the Sierra crest through the weekend. Ensembles then suggest heights lowering slightly over the west and NorCal Monday could bring enough instability over the mountains to produce a better chance of isolated thunderstorms over the Sierra Monday afternoon and evening. HEC

EXTENDED DISCUSSION (Tuesday THROUGH Friday). The synoptic pattern which has been a fixture for much of the summer continues next week. A weak, elongated trough sets up off the coast while a sprawling ridge of high pressure remains fixed over the Four Corners region. Up in the Pacific Northwest, shortwaves will race toward the east, but attendant height falls should remain well to the north of the region. It will prove to be a quiet period over interior northern California with highs running close to mid-August climatology. Some moisture and instability lingering along the Sierra crest could spawn a few showers and thunderstorms on Tuesday, mainly south of I-80. Otherwise, the period is looking quite dry. ~BRO

AVIATION. VFR conditions expected the next 24 hours. Southwesterly surface wind gusts 20-25 knots in the vicinity of the Carquinez Strait/West Delta, particularly after 00Z. Over the northern Sacramento Valley TAF sites, brief north to northwesterly gusts up to 15 knots are possible through 00Z. ~BRO

STO WATCHES/WARNINGS/ADVISORIES. None.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
