AREA FORECAST DISCUSSION National Weather Service Eureka CA 255 PM PST Sun Dec 15 2019

SYNOPSIS. Mainly dry weather is expected through Tuesday. There is the potential for some periods of rain, especially in the north, Wednesday through Friday. There is a better chance for rain on Saturday.

DISCUSSION. High pressure has started building into the area and most of the showers have come to an end this afternoon. Temperatures range from the min 40s inland to low 50s along the coast and in some of the warmer valleys this afternoon. Some high clouds have started to move over the area as a weak warm front approaches the area. This will bring some high clouds to the area tonight. The most recent operational models are keeping the area dry, but it is still possible to see some light rain or sprinkles in the north overnight. The high clouds are not expected to be thick enough in most areas to keep the valley clouds and fog away so expect these will be prevalent across much of the area.

Monday, areas that see low clouds and fog and may struggle to warm up and clouds may not clear until early afternoon. This will likely keep highs in the 40s in many of the interior valleys. Fog is expected again Monday night into Tuesday morning, however southeast flow ahead of the next system may help it to clear out more quickly. This may also help the coastal areas to warm into the low 60s so went above the NBM guidance.

Tuesday afternoon most operational models keep the area dry, however the NBM is showing a slight chance late in the afternoon or evening. Models are showing this system to be a trough approaching the area and then most of the energy going into a cutoff low and and moving into central CA Tuesday night and Wednesday. This is not a high confidence pattern and we could end up seeing more or less rain than currently expected.

Once the previous system moves out of the area the models continue to struggle on the details, but overall the pattern is starting to become clearer. Once the upper low moves out of the area on Wednesday moist west to southwest flow sets up. It looks like a wave moving through will bring some warm frontal precip to the area on Thursday. The main question will be how far south it will make it. The NBM has fairly decent precip amounts in the north, but keeps Mendocino county mainly dry. This boundary could easily move north or south by 100 miles and dramatically change the forecast. Friday there is general agreement that this boundary will shift back north and most of the rain be north of Humboldt county. Saturday at some point it looks like the front will bring widespread heavy rain across the entire area, although it will be fairly short-lived and significant impacts are not expected from this alone. If the northern areas don't see a break in the rain on Friday there is the potential for some flooding, but there is still a lot of uncertainty on this. MKK

AVIATION. Extensive mid to high cloudiness lingers across NW CA this afternoon as showers have tapered off in the wake of yesterday's system. This has left VFR conditions with light winds in place across the area as high pressure builds into the region. Increasing subsidence and residual low level moisture may be enough to generate some patchy shallow fog overnight, but this will also be counteracted by increasing light offshore flow. Therefore, expecting VFR conditions to prevail at the terminals overnight into Sunday, with additional clearing during the day on Monday as the ridge axis moves overhead. /CB

MARINE. Moderate northwesterly breezes behind yesterday's front will give way to generally light southerlies across the area this during the evening. This wind regime is expected to persist through Monday evening, with relatively flat short period seas. The large NW swell which has been moving through the waters for the past several days will therefore remain the dominant wave group through the early part of the week as it slowly decays. The swell is forecast to drop below 10 feet overnight tonight, which should allow to Small Craft Advisories to come to an end by later this evening. Small Craft conditions will then return on Tuesday as southerlies increase ahead of the next system. This looks to be followed by a brief lull on Wednesday before the return of stronger southerlies late in the week. Meanwhile, the next large NW swell will enter the waters by Thursday at around 13-15 ft at 17-18 seconds. This coupled with increasing short period seas out of the south has the potential to create a chaotic and hazardous sea state towards the end of the week. /CB

EKA WATCHES/WARNINGS/ADVISORIES. CA . None. NORTHWEST CALIFORNIA COASTAL WATERS . Small Craft Advisory until 9 PM PST this evening for PZZ450-455- 470-475.
