AREA FORECAST DISCUSSION National Weather Service Eureka CA 240 PM PDT Mon Jul 13 2020

SYNOPSIS. Hot and dry weather conditions will persist over the interior through the week. In addition, a thermal trough will build across the coast today through Wednesday, resulting in warmer temperatures for coastal Del Norte and Humboldt counties.

DISCUSSION. A warming trend for Humboldt, Del Norte and Trinity counties is expected during the short term. Of particular interest, ensemble guidance has less certainty for maximum temperatures near Crescent City Wednesday. Offshore winds and downslope warming could support temperatures in the mid to upper 70s. In addition, statistical guidance for Wednesday based on the NBM shows model solutions ranging from the low to upper 70s. Went with the median value of 74 at this time. Farther inland, northeast ridgetop winds could gust to 30-40 mph tonight and Tuesday night over interior Del Norte County, while at the coast near Crescent City, sustained north-northwest winds will likely be in excess of 20 mph.

Temperatures will remain above normal across much of the interior through the end of the week. Onshore westerly-northwesterly breezes will likely moderate temperatures for the western most coastal valleys. Meanwhile, central and eastern Trinity County will continue to increase to triple digit temperatures. Based on climatology and persistence, the coast will likely experience diurnal stratus development during much of the week . including the Mendocino coast, where a southerly surge of stratus is evident in hi-res deterministic and ensemble guidance Tuesday night into Wednesday.

The current forecast calls for dry weather throughout the next seven days. However, a non-zero threat of an isolated thunderstorm will exist over the Trinity Alps and Yolla Bolly Mountains during Thursday afternoon/evening. Will continue to assess for possible introduction into the forecast during future shifts.

AVIATION. Stratus has cleared coastal areas Monday afternoon, but is forecast to redevelop in the vicinity of Humboldt Bay later tonight. IFR conditions will be possible at KACV as a result. Farther north, offshore winds occurring over interior Del Norte county, combined with northerly surface winds at the coast, may preclude stratus development at KCEC during the night. Meanwhile, a southerly surge of stratus is forecast to occur along the Mendocino county coast Tuesday night. The marine layer depth may be sufficient for stratus spreading north up the Russian River Valley toward KUKI . will continue to monitor during the next 24 hours.

MARINE. Gale force northerly winds continue over the outer waters today. However, model guidance indicates gales will subside over the southern outer waters late tonight. That evolution will likely be followed by solid small craft conditions or borderline hazardous seas. Otherwise, steep short period seas will occur over the southern inner waters during the next 24 hours, and over the northern inner waters through Wednesday night.

FIRE WEATHER. Gusty E-NE winds are forecast to occur over the ridges of Del Norte and northern Humboldt Counties tonight and Tuesday night, with peak gusts upwards of 30-40 mph. Fuels remain marginal in this area for rapid fire growth, however, an elevated fire weather threat will exist due to the combination of gusty winds and modest overnight humidity recovery.

EKA WATCHES/WARNINGS/ADVISORIES. CA . None. NORTHWEST CALIFORNIA COASTAL WATERS . Small Craft Advisory until 5 AM PDT Thursday for PZZ450.

Gale Warning until 5 PM PDT Thursday for PZZ470.

Small Craft Advisory until 5 PM PDT Tuesday for PZZ455.

Gale Warning until 9 AM PDT Tuesday for PZZ475.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
