AREA FORECAST DISCUSSION . CORRECTED National Weather Service Eureka CA 934 PM PST Sat Dec 14 2019

SYNOPSIS. Showers with snow above 2500 feet will continue this evening. Some showers may produce locally heavy rain mixed with small hail and a lightning strike or two this evening along the coast. Drier weather is expected Sunday through Tuesday before another storm brings the potential for rain mid to late next week.

UPDATE. Snow levels dropped quickly as the initial band of heavy showers moved inland earlier this afternoon, bringing accumulating snow to as low as approximately 2500 feet in elevation. This includes several interior mountain passes, including Berry Summit along Highway 299. Snow levels will likely remain near this level through the remainder of the evening, and multiple additional waves of showers can be expected. As a result, 1-3 inches of accumulating snow can be expected between roughly 2500 and 4000 feet in elevation over the course of the evening, with as much as 6 inches of snow possible above 4000 feet. This will primarily occur across Humboldt and Trinity counties, but lighter amounts can also be expected at similar elevations across western Trinity and northern Mendocino Counties as well.

Because of this, a Winter Weather Advisory has been issued for Humboldt and Del Norte counties above 2500 feet through 3 AM Sunday morning.

PREV DISCUSSION. /issued 245 PM PST Sat Dec 14 2019/

DISCUSSION . A cold front is moving onshore this afternoon and brought a short period of rain to the area. Snow levels are around 3,000 to 3,500 feet. Behind the front numerous showers are expected. This is where there is a slight chance for thunderstorms. The 18Z models continue to show over 200 j/kg on the coastal plain of Humboldt and Del Norte counties and over the northern waters. The threat should diminish by 9 or 10pm. Small hail is likely with these showers as well. The airmass doesn't appear cold enough to see widespread hail accumulation on the roadways. Locally heavy rain is expected with these showers, although there may be some breaks in the rain between showers. Rain showers diminish in coverage through the night.

Sunday morning there may be a few lingering showers in the morning, but it is expected to be mainly dry. Sunday afternoon through Monday afternoon some overrunning is expected as high pressure rapidly builds into the area. This is expected to bring widespread clouds and may bring some light rain or sprinkles to Del Norte and Northern humboldt. The models are still struggling to handle feature so confidence is lower than normal on the potential for rain. Snow levels will be around 2,500 feet when this starts, but the warm air advection will warm snow levels through the event. Confidence is fairly high that rainfall amounts will remain less than a tenth of an inch. The threat for rain will diminish Monday afternoon and dry weather is expected Monday night. MKK

Long Term (previous discussion) . GFS and ECMWF have come into much better agreement mid to late next week. Both models are now painting a wet picture compared to the 0z ECMWF from yesterday which had us dry every day next week. It is that time of year for longer duration rain events with atmospheric rivers. Even though the picture is wet for Del Norte and northern Humboldt counties mid to late next week, moderate to heavy rain may not develop for the remainder of the forecast area til Friday night or Saturday when the front finally moves through. The ensemble blended guidance seems to be the most level headed option mid to late next week with precip probabilities trending upward.

AVIATION . Rain accompanying a fast moving front will bring mainly MVFR conditions to local airfields as it moves eastward across the area this afternoon, with brief periods of IFR visibilities in heavier showers. The heaviest rain is expected to the clear the area between 03-06z, with lighter showers and MVFR conditions continuing through late tonight and possibly into Sunday morning. Mostly VFR conditions are expected at UKI as rain will be lighter across Mendocino County. A few thunderstorms will remain possible at CEC and ACV through roughly 04z as a more unstable environment offshore spreads towards the coast. Conditions will improve to VFR across the area during the day on Sunday as high pressure builds over NW CA. /CB

MARINE . A period of fresh northwesterlies will develop across the the coastal waters tonight in the wake of the front, with a few gusts to 25 kt over the outer waters through Sunday morning. This will help to briefly build short period seas into the 7-8 ft range through the first part of the day on Sunday, to pair with the large NW swell which has been the dominant wave group in recent days. Wind will quickly diminish by Sunday afternoon, with primarily light southerlies prevailing through Monday before increasing to advisory level on Tuesday. The NW swell will remain in the 10-12 ft range and continue to necessitate a Small Craft Advisory area-wide through Sunday evening before slowly decaying through the middle of next week. A fresh NW swell train is expected to arrive on Wednesday. /CB

EKA WATCHES/WARNINGS/ADVISORIES. CA . Winter Weather Advisory until 3 AM PST Sunday for CAZ102-105-106.

NORTHWEST CALIFORNIA COASTAL WATERS . Small Craft Advisory until 9 PM PST Sunday for PZZ450-455-470- 475.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
