AREA FORECAST DISCUSSION National Weather Service Eureka CA 255 PM PDT Wed Jul 8 2020

SYNOPSIS. Seasonably warm temperatures across the interior will tend to heat up gradually heading into the weekend, and will be accompanied by sunny skies. Marine air and onshore breezes will keep coastal areas seasonably cool. Areas of coastal stratus will redevelop for the next couple of mornings, particularly over the Humboldt Bay region and in the Eel River Valley, and may be a bit more persistent late this week.

DISCUSSION. It has turned out mostly clear and sunny across almost all of northwest California this afternoon. Stratus was a bit more persistent into the midday hours in some lucky locations along the immediate coast, thanks to a somewhat stronger inversion from increasing temperatures aloft. Otherwise, a stronger pressure gradient along the coast is aiding increasing northerly breezes, with downright blustery conditions found along some of the coastal headlands, particularly near Cape Mendocino southward. These winds will ease heading into Thursday, and model guidance is indicating expanding stratus tonight for all but the northern Mendocino and southern Humboldt coast, which may be more persistent with those winds tending lighter on Thursday. Areas of coastal stratus will likely persist for the same areas through the weekend as ridging tends to build in from the south. This pattern will tend to keep the marine layer shallower, with fog hugging the immediate coast more than inland river valleys, but may also result in low clouds persisting into the afternoon at times.

Plentiful sunshine will be found in the interior every day for the next 7 day. Interior high temperatures will rise into the 90s for the hotter valleys on Thursday. A shortwave trough passing mainly to our north will keep temperatures from heating up to much more through the end of the week. That said, statistical guidance, deterministic models and ensemble systems (GEFS, EPS and CMCE) continue to indicate increasing 850mb temperatures on Friday, generally around 21-23C. The probability of 95F or more at Ukiah is around 22% on Friday. That probability at Ukiah increases to 60-70% over the weekend. Probability of 100F or more at Ukiah increases to 20% Sunday and 30-40% early to mid next week. Stronger warming and increasing heat risk will be possible throughout the interior early to mid next week. There is still a great deal of variance in the pattern Monday through Wednesday due to the depth and eastward progression of another trough in the westerlies across the Pacific NW. This trough may linger over the area and suppress the hot four corners ridge from building north, perhaps keeping temperatures from reaching truly oppressive values in our region.

AVIATION. Offshore stratus consolidated early this afternoon with Eel river valley stratus that had advected and settled inland overnight. What was already a shallow marine layer is expected to diminish mostly although low clouds and overcast conditions have lingered at KACV. As the day progresses most of the stratus will scatter out with the typical diurnal cycle. Gusty north winds are expected near KCEC early evening and should switch to a southern regime late tonight, accompanied with lower ceilings. VFR conditions prevail for KUKI with gusty north winds possible this evening. /EYS

MARINE. North winds of 20 to 25 kt have persisted across the Northern Outer waters today as high pressure builds into Oregon and the pressure gradient tightens up to Cape Blanco. Portions of the waters near and south of Cape Mendocino may see wind gusts near 35 kt later this afternoon and into the evening. Steep seas of around 7 feet at 7 seconds should be expected in this area, with 8 to 9 feet locally downwind of the Cape. Another low pressure trough will act to break down the ridge of high pressure for Thursday and Friday, allowing northerly winds and seas to relax somewhat to the north of Cape Mendocino. Meanwhile, Small Craft Advisories have been extended across the southern outer waters into Friday morning. Otherwise, very little will change in this generally very persistent pattern of northerly wind and seas remaining roughest on the lee side of Cape Mendocino through the weekend and even into next week.

EKA WATCHES/WARNINGS/ADVISORIES. CA . None. NORTHWEST CALIFORNIA COASTAL WATERS . Small Craft Advisory until 5 AM PDT Thursday for PZZ470.

Small Craft Advisory until 5 PM PDT Thursday for PZZ455.

Small Craft Advisory until 9 AM PDT Friday for PZZ475.
