AREA FORECAST DISCUSSION National Weather Service Eureka CA 219 PM PDT Sun Jul 5 2020

SYNOPSIS. Near seasonal temperatures and dry weather will persist during the next seven days. Meanwhile, coastal areas will see a continued marine influence with nighttime and morning low clouds and patchy fog followed by clearing afternoon skies.

DISCUSSION. Another round of marine stratus is probable tonight over the Humboldt Bay area and coastal points north and south. Stratus will clear somewhat during Monday afternoon, followed by redevelopment Monday night. Otherwise, mild and dry conditions will persist across the interior during the next seven days. Diurnal terrain driven winds will be favored during the afternoon hours, followed by light and variable conditions across valley locations. Meanwhile, higher elevation exposed ridges and mountains will experience gusty conditions during the afternoon and night, particularly during Monday as an upper disturbance moves east across the region.

JMG

AVIATION. Stratus has mostly dissipated along the Redwood Coast as of early afternoon, yielding another day of VFR conditions across NW CA airfields. Stratus will continue to follow a typical summertime diurnal trend over the next few days as a relatively deep marine layer (>2000 ft) supports redevelopment after sunset followed by dissipation with daytime heating during the morning hours. KCEC and KACV are therefore expected to return IFR to after 06z this evening, with more VFR conditions on tap for Monday. KUKI and other interior airfields should remain VFR for the duration of the TAF period. /CB

MARINE. Little change is expected in the overall pattern this week as large scale troughing over the NE Pacific maintains a moderate northerly wind regime across the NW CA coastal waters, with minor fluctuations as various embedded waves move overhead. Stronger winds and locally steeper seas will generally remain confined to areas south of Cape Mendocino, where the Small Craft Advisory will remain in effect through at least Monday night. Meanwhile, the advisory for the northern outer zone looks like it will be allowed to expire later this evening as seas gradually trend downward through Monday morning, with lighter northerlies expected to persist north of the Cape for much of the week. /CB

BEACH HAZARDS. A beach hazard statement remains in effect this afternoon but is on track to expire this evening as the long period southerly swell which has been moving through the waters decays to around 3 ft at 16 seconds, bringing an end to the minor sneaker wave threat. /CB

FIRE WEATHER. Critically low RH values will continue across interior portions of NWRN CA through Monday, with poor recoveries expected within the thermal belt located across mid and upper ridge/mountain slopes. Diurnal terrain driven winds are ongoing this afternoon. Valley winds will become light and variable tonight, but gusty conditions will be probable over exposed ridges. Winds may strengthen further during Monday as an upper disturbance moves east across the region . with peak gusts from 25 to 35 mph possible over Lake and southeast Mendocino counties. These conditions will yield an elevated to locally critical fire weather threat.

JMG

EKA WATCHES/WARNINGS/ADVISORIES. CA . Beach Hazards Statement until 8 PM PDT this evening for CAZ101- 103-104-109.

NORTHWEST CALIFORNIA COASTAL WATERS . Small Craft Advisory until 4 AM PDT Tuesday for PZZ455-475.

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.
