AREA FORECAST DISCUSSION National Weather Service Eureka CA 610 AM PST Mon Dec 16 2019

SYNOPSIS. High pressure will yield mostly sunny skies and light winds today. Considerable cloud cover and locally breezy southeasterly winds are expected on Tuesday before a warm front brings increasing probabilities for rain and windy conditions Wednesday night through Thursday. Moderate to heavy rain will be possible this weekend as a front moves across the area.

DISCUSSION. Upper ridging has been resulting in mostly clear skies across the forecast area this morning. As is almost always the case this time of year under clear skies and warming aloft, considerable low clouds and patchy fog has developed over many of the interior valleys of Northwest California. The low clouds and fog will most likely mix out with the daytime heating and mixing later this morning, though with the low December sun angle, it may take til early afternoon to completely scour out.

The next item of interest is a storm/frontal system currently near 140W early this morning. This system will push inside 130W on Tuesday and then elongate and split offshore. It will generate considerable cloud cover as well as locally breezy southeasterly winds. The dry southeasterly and easterly low level flow will likely keep the rain offshore til the 500mb trough passes overhead Tuesday night into Wednesday morning. The GFS and ECMWF were in better agreement on the trough passage, however the GFS was wetter, especially across Mendocino county. If the GFS pans out, 0.25-0.50 of an inch rain will occur in Mendocino county late Tuesday night into Wednesday morning. This will need to be monitored and the next shift may need to boost precip chances and rain amounts.

The precip should start to wind down in the south by Wednesday afternoon, however a wetter storm may start to spread rain into the northern portion of the forecast area as early as Wednesday afternoon. The bulk of the rain with this wetter storm will most likely hold off til late Wednesday night into Thursday. The brunt of the rain with this moist westerly jet will be aimed at the Pacific NW, with Del Norte county likely receiving bouts of heavy rain on Thursday. Current estimates are for 2 to 3 inches from 4PM Wednesday to 10PM Thursday. The heavy rain is expected to tapper off Thursday night and Friday which will mitigate the potential for flooding. A wave should form on the stationary front on Friday as the flow aloft amplifies. Windy conditions are likely in advance of the front that is expect to pass through NW Cal on Saturday. Heavy rain will be possible with frontal passage throughout the forecast. Once again due to the short duration of the heavy rain, flooding concerns remain low at the moment. There are still discrepancies on the timing of frontal passage which may be delayed til afternoon and evening on Saturday. Cooler air aloft and instability will follow behind the front on Sunday for possible showers and lower snow levels. This period of wet and unsettled weather from Thursday trough the weekend will overall be beneficial since we are well below normal on seasonal rainfall.

AVIATION. Low clouds and fog are evident on the nighttime satellite imagery across many inland valleys (including at KUKI). In addition some high clouds are streaming SE across Mendocino County, and mid-level cloudiness is noted brushing N Del Norte County. Otherwise, skies are clear across the area. Inland low clouds should mostly clear by midday. High cloudiness will continue to infiltrate the area from time to time, with clouds thickening tonight. Winds will be generally light across the area, but wind speeds are expected to increase at KACV after midnight tonight, with some gusts to 15 knots possible. /SEC

MARINE. Light southerly winds today will increase tonight, eventually increasing to advisory level across the outer waters by early Tuesday morning. Have gone ahead and hoisted a Small Craft Advisory for that area from 3 AM Tuesday through Wednesday night. There may be a brief period of marginal gale force gusts across the S outer waters Tuesday afternoon, but these winds are expected to be marginal and short-lived. 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 Friday), there is increasing divergence between the model wind fields, and forecast confidence drops to low. W to NW swell will continue through Tuesday. A fresh NW swell train is expected to arrive late Tuesday. This swell will persist through the period. /SEC
