AREA FORECAST DISCUSSION National Weather Service Eureka CA 542 AM PDT Tue Sep 21 2021

SYNOPSIS. Sunny skies, warm and dry conditions will continue today, even at the coastal areas. As an upper level trough passes by, some cooling of the interior is expected on Wednesday and coastal areas may see a few more marine layer clouds.

DISCUSSION. High pressure continue building into the the Great Basin today. The dry offshore northeasterly wind flow continues keeping clear skies. Patches of shallower fog has developed with a good radiational cooling around Humboldt Bay and valleys. Expect a mostly sunny and fairly warm afternoon across the northwest California. A weaker northeasterly wind flow will become southerly by the afternoon, with a lighter winds prevailing. This may also help to warm temperatures on the coast into the 70s, with 80s in the adjacent land areas. While inland highs temperature will be in the 90s. An upper level trough will move into the Pacific Northwest on Wednesday, which will cool down by 10 to 15 degrees the coast. Stratus will be back into several coastal areas tonight through Wednesday morning, with an onshore winds as a result. However, the upper ridge build back very quickly on Thursday and Friday with a weaker offshore flow. This will allow most areas to heat back up, with more dry weather. Saturday, the upper level ridge starts to flatten. This is expected to start to deepen the marine layer and bring some cooler air, but dry weather will persist.

AVIATION. Light offshore winds have kept NWCA nearly cloud-free, with the only obscurations to speak of showing as minor ground fog intermittently popping up in some decoupled valleys and portions of the coastal plain this morning. VFR conditions are expected to persist across the area with light south to southwesterly winds through most of the day. Some guidance is hinting at stratus redeveloping offshore late this evening and tonight, and should this form it may reach portions of the coast by early Wednesday morning. Interior terminals should remain VFR through the TAF period.

MARINE. Light southerly winds develop today across all the waters, with a local southwesterly wind max likely forming this afternoon between Humboldt Bay and Cape Mendocino. Northerlies are expected to return early Wednesday morning and increase through Wednesday afternoon and evening, possibly reaching SCY levels Wednesday night across the outer waters and near prominent headlands. Northerlies then may back off late this week and this weekend, with intermittent southerly reversals nearshore. Locally driven northerly seas follow this pattern as well, building Wednesday night and Thursday before weakening late this week and this weekend. Meanwhile, a series of mid- period NW swells are set to reinforce each other through the forecast period, with new energy showing by Wednesday then fading Thursday and Friday. Another swell should fill in this weekend of similar size but a hair more west and a longer interval. Long-range ensembles are hinting at a trough deepening over the NEPAC early next week, possibly sending us a little more NW energy around mid- week next week.

FIRE WEATHER. The offshore northeast winds weakened overnight, with lighter winds over ridges. Poor RH recoveries this morning with generally 20s to 40s percent on the ridges, while many valley areas were reporting RH over 50s percent. Very dry conditions is expected this afternoon with RH in the 20s and teens, but winds will be very light area- wide. An upper trough will pass through Wednesday with some shifting winds, but they should remain fairly light in most spots and accompanied by some cooling and RH improvement. Otherwise, the rest of the week will remain warm and dry. Another localized surge of northeast winds, particularly over ridgetops, may pass by the Lake County vicinity on Thursday.
