AREA FORECAST DISCUSSION National Weather Service Eureka CA 416 AM PDT Fri Apr 12 2024

SYNOPSIS
The cool-down is underway starting today and into the weekend as amplified upper level trough with the prominent closed low diving south within the base of the trough influencing our weather for the next few days. Light snow is also expected generally above 3000 feet mainly Saturday night into Sunday morning. A warming trend with generally drier conditions is expected for the next work week.

DISCUSSION
As anticipated, the closed upper low is diving south within a highly amplified trough heading toward the coast. A solid band of mid-level sky cover streaming from the southwest in advance of the aforementioned low is evident. Southeast wind will increase today, and continues to look a bit stronger over Lake County with the most likely gusts in the 25-35 mph range. Some instability, strong shear and orographic lift could give eastern Trinity some thunder chances this afternoon and tonight.
Precipitation amounts are near to slightly more than the previous forecast. Convectively driven showers could push snow levels below 3K feet the next couple nights, especially Saturday night.
Models are generally forecasting snow levels to be too high, as seems to be on par for this season. These showers could put down at least a skiff of snow on some higher roads near and above 2500 feet, but still generally not as impactful for most locations compared to the height of winter. North winds are still expected to sharply increase behind the exiting trough after the weekend.
Tuesday is still on tap for some particularly strong gusts over the water and along the coast with the increased pressure gradient. /MH

AVIATION
An approaching weak shortwave trough streams high cloud over the area this morning while disrupting the marine layer...allowing for primarily VFR to continue. Some remnants of the MVFR ceilings from yesterday afternoon are still lingering, and may briefly drift over the coastal terminals early this morning, however these are expected to be short lived. Low cloud may spill into Ukiah from the west early this morning, but confidence is low as to whether or not this will occur, and if it does this cloud should be short-lived and mix out by late morning.

Otherwise, VFR is expected to continue across the region through most of today under high cloud. Some MVFR ceilings are possible this afternoon as small scale eddies within the approaching low spin up nearshore, but confidence is low with how and precisely when these features will impact the coastal terminals. Have hinted at ceiling heights in the coastal tafs for now. Light rain slowly spreads across the region tonight, along with MVFR ceilings and vis in Mendocino late tonight, possibly impacting KUKI.

MARINE
Winds continue to weaken this morning as a broad surface low approaches and tracks southeast over the offshore waters. Wind directions will become much more variable and chaotic through the day as multiple small scale eddies spin up nearshore and a front stalls offshore. Thus, wind directions are forecast to become much more variable. For the most part, sub-advisory speeds are forecast (less than 20kt), although brief and localized gusts up to 20 knots are possible (<20% chance) with mesoscale circulations.

Potential (<30% chance) for localized or isolated gusts to 25 kt will continue on Saturday as broad and diffuse low pressure remains over the area, while the main core of the low center heads southward into Central California. Potential (>60% chance) for widespread northerly gusts 25-30 kt will increase on Sunday as surface high pressure builds toward the coast from the west. Pressure gradient tighten more by Monday and potential (>70% chance) for gusts to 35kt will increase, mostly downwind of Cape Mendo.

A mid period WNW swell is forecast to continue to decay over the next few days, while short period northerly have mostly filtered out overnight. A fresh NW swell is expected this weekend, likely filling in during Saturday. A steady build up of steep northerly wind waves in conjunction with stronger northerly wind is anticipated for early next week. DUG
