AREA FORECAST DISCUSSION National Weather Service Eureka CA 330 AM PDT Sat Aug 8 2020

SYNOPSIS. Building heat is expected over the weekend and early next week throughout inland areas, with mild but sunnier conditions along the coast as well. Slight chances for thunderstorms exist across interior mountains Monday.

DISCUSSION. Main weather issues continue to be increasing temperatures inland, shrinking marine layer, and potential isolated thunderstorms across the eastern interior on Monday. Afternoon temperatures will rise a few degrees today followed by another notable rise on Sunday reaching between 100 and 104 degrees across many interior valleys. Forecast models still indicating a weak depression moving into the Bay Area which may promote thunderstorm activity across northern CA and may bring afternoon storms to the usual spots along the Yolla Bolly spine and Trinity Alps. Along the coast, mild conditions continue through the week, although a much shallower and weaker marine later will allow for sunnier skies. While some shallow stratus and fog may develop in places during the overnight periods, particularly in the vicinity of Humboldt Bay, marine clouds are likely to be less widespread and quicker to burn off during the day bringing some nice weather back to the coast.

AVIATION. Expect patches of stratus to develop around Humboldt Bay by daybreak, with possible IFR/LIFR ceilings in the vicinity of KACV through mid morning. Light mist has formed at KCEC, however brisk northerlies offshore will likely result in rapid improvement by 16Z. KUKI and other interior airfields should remain VFR through the period. Patches of stratus and mist will likely redevelop around Humboldt Bay and the Eel Delta late tonight. Also, a southerly wind reversal will advect central California fog and stratus northward onto the Mendocino coast late tonight.

MARINE. A tight pressure gradient between high pressure offshore and a thermal trough along the northern California coast will result in strong northerly winds through early next week. Gale force winds are expected north of Cape Mendocino today through Sunday night, primarily outside 20NM from shore. Low end gales with gusts to 35 kt will also be possible south of Cape Mendocino outside 20NM. For now will stay with a Hazardous Seas Warning for very steep short period seas from 12 to 16 feet. Small Craft Advisory conditions will remain present over the nearshore waters for the next several days, with localized gale force gusts and larger steep seas found near Pt St George and Cape Mendocino. Near Pt St George, gusts around 40 to 45 kt are expected this afternoon and evening. For Mendocino nearshore waters, north winds should abate tonight and switch to light southerly on Sunday south of Shelter Cove. Seas will likely remain steep and hazardous through at least Sunday morning.

Winds look as though they will finally relax somewhat towards the middle of next week as weak troughing develops over the West Coast. Northerlies can be expected to persist for the foreseeable future. Small scale eddies will likely spin up, resulting in localized southerlies from time to time.

FIRE WEATHER. Increasing temperatures and corresponding lower RH values are expected through early next week. This combined with a light but persistent offshore flow at night will also contribute to a reduction in RH recoveries . especially along the upper slopes and ridge tops. Afternoon temperatures are expected to reach near 100 degrees today across many interior low elevations, and will likely peak at between 100 and 105 degrees Sunday and Monday. Daytime winds will generally be driven by terrain backed by but a westerly component. Some stronger overnight offshore gusts are also likely across the ridges of Del Norte County through the weekend. In addition, unstable conditions and deep mixing heights will also likely develop each afternoon late in the weekend and early next week. No thunderstorms are expected today and likely Sunday as well, with slight chances returning to the area Monday. Uncertainty remains high, and greater probabilities likely exist farther to the east. Any storms that produce lighting may be initially dry.

EKA WATCHES/WARNINGS/ADVISORIES. CA . None. NORTHWEST CALIFORNIA COASTAL WATERS . Small Craft Advisory until 11 PM PDT Sunday for PZZ450.

Gale Warning until 3 AM PDT Monday for PZZ470.

Small Craft Advisory until 9 AM PDT Sunday for PZZ455.

Hazardous Seas Warning until 3 AM PDT Monday for PZZ475.

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.
