A weak cold front tonight will bring another round of drizzle and fog, mostly restricted to the far north coast. A brief return of warm interior weather and marine stratus is expected Tuesday before another front cools conditions back down later in the week.
Benign late spring heat continues for the interior with the hottest valleys poised to reach 80 later this afternoon. Warm air has helped stick the marine layer along the coast, keeping the beaches cool right around 60. Low pressure approaching the coast has helped raise the marine layer around 2000 feet, brining mild weather as high as Kneeled. Some brief scattering is expected this afternoon under strong afternoon heating, especially Humboldt Bay and south.
The HREF shows stratus and fog quickly reforming this evening before sun set. A cold front crossing the coast overnight will destabilize the marine layer without bringing enough lift to mix out the inversion. This combination will likely bring some light drizzle to much of the coast. Amounts are expected to total only a few hundredths of an inch at most. Dry air aloft will inhibit any measurable precipitation for the interior, with high clouds and a northerly wind shift being the only sign of frontal passage. Some valley fog is expected near the coast Monday with interior temperatures cooling by about 5 degrees. Cooler air should help with more robust clearing along to coast on Monday.
High pressure will build again Tuesday returning the interior to the low 80s with a weak marine layer, mostly restricted around Humboldt Bay. All cluster ensemble members show another cold front passing through around early Wednesday. This front should be slightly stronger than Monday's, but still not more than a tenth of an inch of precipitation is expected along the coast. This front will welcome cooler weather for the second half of the week along with clearer skies for the coast. About 70% of cluster ensemble members have strong high pressure building in for next weekend, which could bring some of the seasons first 90 degree temperatures for the interior. /JHW
Light to gentle W to SW breezes continue across the coastal waters this afternoon. Northerly winds will develop this evening and increase across the area early next week, reaching advisory criteria in the southern waters by midday Monday. Look for the strongest winds S of Cape Mendocino where gale force gusts will be possible on Tuesday as a surface ridge builds behind the next frontal system. Seas around 5 feet are expected to continue through early this evening, then short period northerly seas will build tonight and early next week.
