A weak frontal system will clip the northern portion of the area tonight, bringing a chance of light rain or drizzle to the North Coast tonight and early Wednesday. Dry weather will return late in the week and continue into early next week.
After lots of low clouds and areas of fog along both coasts this morning skies are improving Humboldt Bay and southward. This is mainly in response to an upper level trough approaching from the west and mixing out the stubborn coastal inversion that has trapped the clouds and fog over the last few days. Pics from space still showing persistent low clouds northward but should just be a matter of time before those coastal areas also see improvement in sky conditions. Mainly sunny again across the interior zones but temperatures will be moderating Wednesday as the upper trough digs off the Pacific NW coast and ushers in cooler air. An associated weak front will move across the North Coast late tonight and early Wednesday bringing a chance of light rain or drizzle to mainly the coastal and coastal interior areas...but should end by midday. The latest models are indicating a bit more rain across Del Norte County (perhaps as much as a quarter of an inch across the windward terrain). Additionally, measurable rain (albeit light) may occur farther S into N Humboldt County. Otherwise, generally dry weather is expected to continue through the remainder of the workweek. The latest models continue to indicate a ridge over the West Coast over the weekend with the potential of an omega block pattern.
Light variables breezes have begun to transition to more of a southerly wind as a weak front begins to approach the coast. . Frontal passage will occur early Wednesday morning and could briefly increase winds with gusts above 20 knots. Northerly winds will return behind the front and slowly build back to strong breezes by Thursday. Modest wind speeds will keep short period seas below 6 feet through Thursday. Overall sea state will remain fairly tranquil until midday Wednesday when northwest swells will start to build...reaching around 10 feet at 10 seconds. With mostly calm wind waves, the forerunners of this swell could pose a minor sneaker wave threat on local beaches late Wednesday afternoon and evening.
