AREA FORECAST DISCUSSION National Weather Service Eureka CA 349 PM PDT Tue Mar 31 2020

SYNOPSIS. A few showers will linger across the coastal mountains this evening, otherwise expect clearing skies for most areas tonight, aside from valley fog. Mainly dry weather is expected Wednesday through Friday, with some cold and frosty mornings, especially Thursday. The weekend is looking wet, with mountain snow.

DISCUSSION. A cold front oriented somewhere near or just south of Cape Mendocino will continue to drift south of the area tonight, while gradually dissipating. Shower activity has already shifted inland and begun decreasing in coverage, and will continue to do so this evening. That said, there will continue to be scattered shower activity lingering over the interior mountainous terrain for awhile longer, particularly in Humboldt and Del Norte Counties. All of this will diminish overnight, though with the passage of a secondary upper- level trough, some shower activity will linger over the coastal waters into Wednesday. Additionally, a few isolated pop-up showers may be found tomorrow afternoon along the periphery of our CWA, where our counties meet Siskiyou County. Otherwise, we are looking at a break in the wet weather for the next couple of days for the vast majority of northwest California.

Building high pressure over the eastern Pacific will begin sending drier air into our area on northwest winds this evening and tonight, which will allow for clearing skies. Lake County has already cleared out in fact, with clouds scattering in much of Mendocino and eastern Trinity County as well. We may see some sun at the coast with sunset. With calming winds tonight, most valleys and low-lying areas will see fog develop tonight, though expect the coast to stay mostly devoid of thicker fog and stratus. This fog and lingering low-level moisture should preclude much in the way of frost formation, and limit valley and coastal low temperatures from dropping below 36 degrees outside of perhaps some localized locations in interior Mendocino and Lake Counties (and of course Trinity County). Gusty northwest winds developing Wednesday afternoon will allow us to dry out, limiting fog and allowing for a colder night heading into Thursday morning. Prepare for a widespread frost away from the immediate coast in most of our area, with freezing temperatures for many interior areas.

Next weekend continues to look active, with the next system set to arrive as early as Friday night. This does not look like a terribly impactful system, but depending on the strength and track, could bring a good dose of mountain snow and even possibly some small hail showers to the coast. Stay tuned as details become more certain while we draw closer to the weekend. /AAD

AVIATION. A front passed through the north coast this morning bringing rain and lowering visibility. As the day progresses, ceilings rise and showers are less frequent for all terminals in the CWA. Low clouds and localized fog may develop in the inland valleys overnight before more widespread clearing is expected during the day on Wednesday. /EYS

MARINE. NW swell and local seas have combined to make seas around 10 feet in the Northern Outer waters. Thus, a small craft advisory is in effect for Northern Outers until this evening. Northerly winds strengthen tonight in the Southern Outer waters and widen to Southern Inner waters Wednesday morning as the pressure gradient focuses towards the coast. SCY is in place for those as well. Northerlies should continue through late this week before breaking down as another system approaches the coast this weekend. Otherwise, after the current mid- period NW swell filters out late tomorrow, seas should be dominated by local, short- period wave generation through the rest of this week. /TDJ /EYS

Small Craft Advisory from 9 AM to 9 PM PDT Wednesday for PZZ455.
