AREA FORECAST DISCUSSION National Weather Service Eureka CA 427 AM PST Sun Dec 15 2019

SYNOPSIS. Weak shower activity will persist today and may continue into tonight. Dry weather is expected on Monday and Tuesday before showers return around mid week.

DISCUSSION. Shower activity has been generally diminishing in coverage and intensity overnight with warmer cloud tops noted offshore over the coastal waters. Moist onshore flow in the wake of a cold front will likely result in weak convective activity today and perhaps into tonight. The higher resolution model guidance seemed to capture this the best, with the bulk of the precip north of Cape Mendocino in Humboldt County and over the mountains.

Warming aloft and light easterly flow in the lower atmosphere should put an end to the shallow convection on Monday. The ridge will likely start to shift eastward on Tuesday as a splitting trough approaches 130W. We will probably see considerable mid and high cloud cover in advance of this system. The models continue to be all over the place on the evolution and track of this splitting trough. The GFS has a northern track which would likely bring rain to the area on Wednesday. The ECMWF has a southerly track, resulting in less potential for rain, especially for the northern most part of the forecast area. Eventually, an upstream kicker will propel this upper low eastward and open the door for more rain. A moist westerly flow is expected to bring rain back into the northern most portion of the area on Thursday.

The forecast late next week remains elusive with both the GFS and ECMWF indicating the potential for a longer period of moderate to heavy rain. This may not occur until Friday night or Saturday when the front moves across the area. Overall, it does appear like an active wet pattern typical for the latter part of December. Due to consistent model variability and slight deviations in the position of the AR, opted to follow the NBM as primary guidance. The rain appears to be mostly beneficial, though minor flooding concerns will need to be evaluated as the event grows closer and confidence increases.

AVIATION. Shower activity has become less widespread and generally lighter over the past several hours, and expect this trend to continue through the remainder of the morning hours. Broken low clouds are expected to continue through most of the day, although there may be some scattered periods along the Redwood Coast during the afternoon. Winds will be light. /SEC

MARINE. NW winds will continue to diminish this morning with light southerly flow returning on Monday. Southerly winds will increase Monday night, eventually increasing to advisory level across the outer waters by Tuesday morning. There may be a brief period of marginal gale force gusts across the S outer waters Tuesday afternoon. Wind speeds are expected to decrease again on Wednesday, then more strong southerlies are possible by Thursday. By the end of the forecast period (late Thursday), there is increasing divergence between the model wind fields, and forecast confidence drops to low.

W to NW swell at 10 to 12 ft will continue to necessitate a Small Craft Advisory area-wide through this evening. This swell will continue into the middle of the coming week, but it will gradually subside to 8 to 9 ft. A fresh NW swell train is expected to arrive late Tuesday. /SEC

EKA WATCHES/WARNINGS/ADVISORIES. CA . None. NORTHWEST CALIFORNIA COASTAL WATERS . Small Craft Advisory until 9 PM PST this evening 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.
