AREA FORECAST DISCUSSION National Weather Service Eureka CA 255 PM PST Tue Jan 26 2021

SYNOPSIS. A significant winter storm will bring widespread rain along with heavy snow and strong winds through this evening with lingering rain and snow showers into Thursday. Additional rain and snow is expected into the weekend and early next week.

DISCUSSION. A potent storm system continues to move toward the coast. Widespread rain and mountain snow precedes the storm system, with inland snow levels running between 1500 and 2000 feet. Snow levels are forecast to gradually rise through the night, but some valleys may continue to have trapped cold air producing lower snow levels. Confidence remains high for snow levels to range from 1000 to 1500 from Trinity County into interior Del Norte and Humboldt, supporting 1-2 feet of snow along much of the Hwy 299 corridor from Berry Summit eastward to Weaverville. South of Hwy 36, the bulk of snowfall will be above 2000-2500 ft for southern Humboldt and Trinity and above 2500-3000 ft from interior Mendocino into Lake County. Overall, the rain and snow forecast remains generally unchanged. Wind Advisories continue into the evening hours for low- level wind gusts up to 50 mph and higher elevation gusts over 60 mph.

A line of thunderstorms has developed about 50 NM off the North Coast, and this line is presently moving ESE. There are several weak rotational couplets along this line, and there have been indications of a possible meso-low with warming cloud tops to the SW and and increase in lightning to the E of the low well offshore Cape Mendocino. As a result, have expanded scattered thunderstorms across the N coastal waters into the coastal plain from Cape Mendocino to the OR/CA line. These thunderstorms have the potential to drag a strong low-level jet to the surface and produce winds in excess of storm force, in addition to isolated waterspouts. Around 130 PM, We issued a Special Marine Warning for portions of the coastal waters, and this line will continue to be monitored.

Overnight, activity will be briefly waning after the passing of an occluded front, before ramping back up as the parent upper-low rotates closer beginning in the early morning hours of Wednesday. Dynamics will favor a transition to convective showers at this time with a steepening lapse rate and weak instability, thus the threat for small hail will need to be monitored. It appears that the best chance of thunder will shift S of Cape Mendocino with this feature.

The highest precipitable water anomalies will sweep through late this afternoon, but will be highest S of Cape Mendocino where lower elevations can around 2.5 inches of rain in a six hour period. This area will need to be monitored for areal flooding issues through Thursday. Snow elevations will begin to lift later Wednesday. Blocked by a building ridge to the east, the upper low will lurk offshore while quickly filling, keeping the weather unsettled through Thursday. /JJW&SEC

Long Term (Friday through Monday). The ensembles take a break in the heavier rain on Friday as a transitory ridge moves through the area. There will likely be some light showers around, but overall it is expected to the driest day of the week. Friday night or Saturday models are showing a weak front that moves through fairly quickly. Snow levels with this system are expected to be range from 3,000 to 4,000 feet. Once this moves through will likely be another short break in the precip at some point on Saturday.

Sunday into Monday the ensembles, especially the GEFS, are starting to show a weak AR stalling out over the area and lasting for 24 to 30 hours over the area. This system looks looks quite a bit warmer than the ones we have been seeing with snow levels rising over 4,000 feet. This is still a ways out, but there is the potential for some main steam river flooding with this system. MKK

AVIATION. A strong frontal boundary brought rain and increasing southerly winds across the NWRN California late this morning. Rain is expected to intensify by evening as the cold front moves over the CWA. VFR to MVFR conditions with occasional dipping to IFR at times in periods are expected through the TAF period at all terminals as it moves through. Strong surface wind gusts around 35 to 45 mph is impacting the coastal terminals, reaching 50 mph at CEC during the afternoon. Low level wind shear has developed at the coastal terminals reaching 60 kt at 2000 feet. Gusty southerly winds are also expected at KUKI by late this afternoon, however the strongest winds are forecast to remain 1000 to 2000 feet above MSL. Thus, low level wind shear will also be possible at KUKI through late evening. Behind the front wind will diminish this evening and rain will become more showery later this evening. MVFR conditions may linger through the evening. ZVS

MARINE. Gale to storm force southerlies has develop across the waters as a strong frontal system moves through. Sustained wind speeds of 35 to 45kt with gusts up to around 55 kts will continue through this evening. The Storm Warning for the northern outer waters is in effect through this evening, with Gale Force Warning for the rest of the waters as well. There will be a brief lull late this evening and into tonight, but southerlies will quickly ramp up again Wednesday morning. Mostly fresh to strong breezes are expected with this second burst and will weaken as we head into the overnight period on Wednesday. Northerlies will develop on Thursday, but this will be shortlived, as southerlies redevelop ahead of the next system approaching the area later on Friday. Models are then keeping winds elevated over the waters, mostly in the moderate to fresh breeze range through at least the weekend.

Short-period seas has developed throughout the coastal waters in response to the rapid increase of the winds. A west to northwest swell around 10 to 13 feet at 13 seconds will continue decay through late evening. An additional westerly swell is set to replace the decaying swell on Wednesday. This second swell will peak around 17 to 19 feet at 16 seconds Wednesday evening. Guidance then shows yet another westerly swell moving through the waters overnight on Friday. MKK/ZVS
