Synopsis for the central california coast and bays including the Monterey bay - Greater farallones - .and cordell bank national marine sanctuaries - . Fresh northerly winds continue over the outer coastal waters today, with gale force gusts expected over the northern outer waters through early Wednesday morning. As high pressure strengthens and moves eastward, winds begin to diminish late tomorrow night. Winds from late tomorrow night through the weekend are expected to be predominantly gentle to moderate. Portions of the northern outer waters may see peak wave heights between 12-16 feet through the late afternoon of Wednesday.

AREA FORECAST DISCUSSION National Weather Service Eureka CA 318 PM PDT Tue Jul 2 2024

SYNOPSIS
A very strong heatwave will build in today bringing Major to Extreme HeatRisk and near record breaking temperatures across the interior Wednesday through the weekend. Heat and very dry humidity will also enhance fire weather concerns, especially today and Wednesday.

DISCUSSION
Temperatures will continue increasing today with interior temperatures reaching above 100 throughout the interior, but especially in Lake and Mendocino Counties. Rapid warming and drying will continue through Wednesday. The southern half of the area will see temperatures peak on Wednesday. Major to isolated Extreme HeatRisk is expected throughout interior valleys, but especially around Clear Lake and within the Russian River Valley. In both areas, NBM shows a 60 to 80% chance of highs in excess of 110 Wednesday. Such temperatures are either record breaking or very nearly for all across the southern half of the area. HeatRisk is bolstered by the fact that overnight conditions will bring very little relief. On valley bottoms, most likely lows are around 70 with strong thermal belts creating midslope lows closer to 80 by Wednesday morning.

Model ensembles have come to better agreement on the development of the ridge through the week. While most models still show a weak surface low forming off the coast of Central California, few models show it having much impact on the heat. Though it may slightly weaken heat for the southern half of the area, it will mostly just shift the focus of heat further north into Trinity and Humboldt by Thursday. Regardless, near record breaking heat will continue for the entire interior through through the week. Conditions will be dangerously hot along the Trinity River by Wednesday and into this weekend, NBM shows a 70 to 90% chance of highs above 110 all along the Trinity River Valley. HeatRisk is only slightly diminished in the north thanks to lower nighttime temperatures closer to 60 through the week.

Heat will even begin to move towards the coast as the week wears on and onshore flow continues to weaken. High pressure settling through the week will help create an increasingly shallow marine inversion which may, at times, be totally pushed offshore by easterly nighttime winds. While a sea breeze will cool off coastal areas each afternoon, increasingly clear and hot mornings may allow high to approach 80 by late in the week. By Thursday and Friday, NBM shows a 50 to 70% chance of brief highs over 80 as close to shore as Arcata and downtown Crescent City.

The vast majority of cluster ensemble members show the ridge persisting and only very slowly beginning to break down late this weekend. By Sunday, only 10% of members show the ridge pushing east.
Even by next Tuesday, 50% of ensemble members still have the ridge sticking around, albeit slightly weakened. All that is to say, all indicators point to strongly above average temperatures being here to stay for the foreseeable future. /JHW

AVIATION
VFR conditions are expected to prevail across all of Northwest California for the next 24-36 hours as dry air moves in along the coast and the interior heats up. There could be some clouds forming along the north edge of the King Range tonight into the area of Fortuna but any development should be limited and unlikely to reach ACV. Gusty coastal winds will exist this afternoon/evening as strong gales over the coastal waters influence coastal areas. Winds will decrease overnight only to increase again tomorrow afternoon. /RPA

MARINE
A tight pressure gradient over the coastal waters with the thermal trough strengthening over the interior is resulting in strong gales in the outer waters. Steep seas will propagate toward the coast bringing hazardous seas to waters north of Cape Mendocino through Wednesday. Winds will decrease sharply beginning Wednesday night into Thursday as the tightest pressure gradient moves west outside of the waters. Light to moderate southerly flow is likely to return near the coast with the potential for a coastal stratus surge Thursday into Friday. Northerlies return over the weekend as high pressure strengthens off the coast. /RPA

FIRE WEATHER
The building heatwave will bring enhanced fire danger through the week, but especially today and Wednesday. As highs climb well above 100, RH will crater with most interior valleys very likely (80% chance) to see minimum RH between 5 and 10%. Overnight conditions will bring little relief with very poor RH recoveries of 30 to 40%. Even with only gentle terrain winds, such dry conditions will promote critical fire weather conditions each afternoon.

There are several areas where enhanced winds will generate more widespread and long lasting critical conditions. First, as the high first builds across the area, a building pressure gradient aligned with the Sacramento Valley will promote gusty northeast winds along the Sacramento foothills with sustained winds of 12 to 18 mph. Such winds have already been observed this morning with very poor RH recoveries barely above 20 percent. Though restricted to ridgetops at night, such winds will mix down more broadly early each afternoon. For the forecast area, afternoon mixing will promote widespread critical conditions in southeast Lake County today and Wednesday, prompting a Red Flag Warning in the area.

Elsewhere, periods of critical fire weather are expected during the afternoon where terrain winds are enhanced, such as along the Trinity River Valley. Strong thermal belts will help promote critical conditions even at night, with moderate, dry northeast winds building each night on high ridges, especially in the Klamath Mountains. Fire Weather conditions will only slightly begin to ease by this weekend. /JHW
