AREA FORECAST DISCUSSION National Weather Service Eureka CA 425 AM PDT Wed Aug 5 2020

SYNOPSIS. An upper level trough will bring relatively cooler air to northwest California Thursday, with a deep marine layer and more widespread and persistent coastal clouds. Stray thunderstorms might be found around the mountains of northern Trinity County this afternoon. Inland temperatures will be heating back up starting Friday.

DISCUSSION. Marine layer cloudiness continues to hang around the northwestern coast this morning, with local profiler data indicating that this layer is currently around 3500 ft deep. While the marine layer should begin to slowly shrink this afternoon as an upper level trough exits to the east, expect stratus to continue to linger around the coast and push inland once again tonight. Model guidance is indicating strengthening northerly flow building over the coastal waters trying to impinge on Point St George beginning this afternoon, along with light nocturnal offshores beginning to develop during Thursday night as upper level ridging builds overhead, and these both should help to further erode the marine layer in the back half of this week, particularly in Del Norte county. Meanwhile, interior areas will continue to trend a bit cooler both today and tomorrow.

Isolated thunderstorms remain possible around the Scott Mountain summit vicinity and the northern portions of the 'Trinity Horn' this afternoon . however the better threat continues to be farther north into Siskiyou County, as the upper level trough triggering convection will begin lifting out to our northeast this afternoon, with decreasing mid-level lapse rates and warming temperatures aloft.

That warming aloft will continue into Friday and the weekend as upper-level ridging builds back in, effectively suppressing the marine layer and possibly restricting it to the overnight and morning hours along the immediate Humboldt coast, and perhaps parts of the southern Mendocino coast. Afternoon northerly breezes along portions of the coast might help some areas clear out as well, but will also keep it a bit cooler. Meanwhile, inland areas will heat back up, with plenty of 90s and even some low-to-mid 100s for highs in the hotter valleys this weekend. /AAD&TDJ

AVIATION. Marine stratus once again shrouded the northern California Coast overnight, both CEC and ACV remain overcast with CEC lifting to MVFR early this morning while ACV remains LIFR at time of writing. Del Norte may see more substantial clearing today compared to yesterday as northerlies increase this afternoon, with low clouds returning this evening and tonight. Farther south in Humboldt, stratus will likely follow a similar trend today as yesterday, with ceilings lifting to MVFR levels and only partial clearing if there is any clearing at all, followed by another round of IFR to LIFR ceilings and visibilities tonight. Some clouds are building near UKI early this morning, however these should clear out by mid-morning.

MARINE. Moderate northerly winds and steep seas will continue throughout the waters, with strongest gusts occurring in the lee of Cape Mendocino where gusts as high as 25 kt are likely occurring. Small craft conditions continue for the northern and southern outer waters, and southern inner waters until midnight. Otherwise, marine conditions will tend to improve slightly throughout tonight and Thursday as high pressure over the Pacific tends to weaken a little bit more, allowing for a weaker pressure gradient. However, northerly winds are expected to increase during Thursday night in the outer waters due to the strengthening of pressure gradient.

FIRE WEATHER. An upper level trough will continue to bring modest cooling and improvement in humidity through Thursday, especially where the deepening marine layer reaches inland. The trough will also bring a small chance for thunderstorms over the higher terrain of northeastern Humboldt and northern Trinity counties this afternoon, primarily in the alps and around the Trinity Horn, thus we will continue to have a headline for fire weather zone 283. Warmer temperatures and drier conditions are expected to return for the end of the week and the weekend, with light offshore flow during the nights and mornings.

EKA WATCHES/WARNINGS/ADVISORIES. CA . None. NORTHWEST CALIFORNIA COASTAL WATERS . Small Craft Advisory until midnight PDT tonight for PZZ455-470- 475.
