AREA FORECAST DISCUSSION National Weather Service Eureka CA 447 AM PST Sat Jan 25 2020

SYNOPSIS. Rainy conditions can be expected today through mid-day Sunday, with only short breaks in between. Rain will diminish Sunday afternoon, but additional light rain will be possible in Del Norte and Humboldt county Sunday night and Monday, and everywhere Tuesday. More light rain is possibly late Wednesday, with a warming and drying trend through the end of the week.

DISCUSSION. After a brief lull in precipitation overnight, rain is beginning to redevelop across Humboldt and Del Norte counties as a warm front approaches the coast. This rain will steadily increase through the day, kicking off what will be a wet and generally gloomy weekend for the most part. Rain rates will likely peak in between the mid afternoon and early evening hours, perhaps approaching 1/4 inch to 1/3 inch per hour in favorable mountain ranges like the King Range, and between 1/10 inch and 1/4 inch per hour elsewhere. After another short lull in rain rates during the late evening, another surge in rain can be expected overnight and early Sunday morning, again with similar moderate to heavy rain rates as the round prior.

In any case, rain rates such as these over a period of roughly 12 hours (after subtracting the lulls) is not likely to generate major negative impacts throughout the region, and can generally be filed as "beneficial". However, some areas may see some minor flooding issues like ponding on roadways and in poor drainage areas, along with rapidly rising creeks and small streams. Main stem rivers are not expected to flood, or even approach flood stage, although they will see increased flows. By Sunday afternoon rain will gradually diminish, with an outside chance at a few peeks of sun along the coast during the mid to late afternoon. By the time all is said and done, most areas in Humboldt and Del Norte counties will see an additional 1 to 2 inches of rain, with some totals climbing to near 3 inches in the mountains. In Mendocino and Trinity counties, an additional 1/2 to 1 inch of rain is more likely. Snow levels will remain generally high throughout the event, keeping heavy snow accumulations restricted to the taller peaks of the Trinity Alps. Snow levels will likely fall to near 4500 feet by Sunday morning, which may bring a light dusting to Scott Mountain Summit on Highway 3.

By Sunday night, an atmospheric river will begin to impact primarily the Oregon coast, bringing more heavy rain to our northern neighbors. However, while we will likely not bear the brunt of this next round of rain, some light rain will likely extend into Del Norte and northern Humboldt counties overnight through Monday, maintaining gloomy conditions in places like Crescent City, Gasquet and Klamath. Meanwhile, Mendocino and Trinity counties will likely stay dry through Monday evening. Overnight Monday through Tuesday, a cold front will push slightly heavier rain south and into most areas, although the heaviest rain will once again remain in Del Norte and Humboldt counties. Once again, major negative impacts are not anticipated.

From Wednesday through the end of the week, building high pressure will gradually push the storm track farther and farther north into the Pacific northwest. This will limit that ability of cold fronts to bring substantial rain into the region, although additional light rain will be possible late Wednesday. Temperatures will also likely increase gradually through the end of the week, perhaps reaching well into the 60s by Friday across interior valleys. /BRC

AVIATION. Yet another weak front moved ashore early this morning, with LIFR to IFR ceilings and visibilities north of Cape Mendocino. These should clear out later this morning with widespread MVFR to VFR conditions arriving by midday. However another frontal system is expected to impact the area this evening, which should incrementally drop regional ceilings and visibilities to IFR once again by late tonight. /TDJ

MARINE. Light southerly winds persist this morning before increasing once again across the waters this afternoon, peaking late tonight. Southerlies then weaken somewhat tomorrow morning and shift westerly through the first half of the day, but then turn back to relatively southerly and fluctuate around low- end SCY levels for the foreseeable future as a series of weak upper- level shortwave troughs pass overhead. A persistent local wind speed maximum in the northern outer waters will continue to oscillate in strength with each passing pulse.

Seas weaken slightly this morning as a long period west swell decays. Current model guidance is showing combined seas briefly dropping below 10 ft this afternoon and evening for the inners and southern outers . thus have kept the current trajectory of dropping SCY's for these zones this morning. This will be re- evaluated with the morning update. Short period seas increase as the day progresses in response to accelerating southerlies, likely reaching SCY levels in the northern waters by tonight, but this short period energy should filter out by Sunday morning. Otherwise, yet another solid west swell is expected to fill in on Sunday afternoon, keeping seas elevated well into next week. /TDJ
