AREA FORECAST DISCUSSION National Weather Service Eureka CA 400 AM PDT Fri May 10 2024

SYNOPSIS
General offshore flow influenced by a Pacific ridge of high pressure will continue to bring warm and dry conditions through Saturday. Unseasonably warm and possibly record high temperatures could occur along the coast today. Saturday will most likely see a return to more seasonable temperatures along the coast. A cooling trend is expected for Sunday and Monday with warmer temperatures returning for the middle of the week.



DISCUSSION
A high pressure system in the Northeast Pacific will continue to influence offshore flow today and into the early weekend.
As a result, dry and warm conditions will continue. Expansive coastal stratus and fog is unlikely to develop early this morning; however, some patchy ground fog may develop due to light winds, especially around Humboldt Bay. Also, unseasonably warm temperatures are expected along the coast due to the offshore flow. High temperatures in the upper 60s to mid 70s are possible. Inland temperatures are anticipated to peak in the upper 80s and potentially up to 90 in the warmer valleys.

Tonight and into Saturday, the upper level ridge is forecast to begin to flatten. Due to the flattening of the ridge, a southerly surge of winds could develop south of Cape Mendocino bringing the potential for some stratus along the North Coast. Although, due to this being such a localized event, models are having a difficult time determining this possibility. However, despite this, temperatures will likely cool at and near the coast, while still remaining mostly in the lower 60s. Farther inland, temperatures are forecast to remain similar to today.

Saturday night and into Sunday, a trough will move closer to the area ushering in a deeper and more widespread marine layer by Sunday morning. Drizzle may occur along the coast, as a result.
Temperature-wise, inland areas are expected to drop into the low to mid 80s. A shower or two is possible over the higher terrain of eastern Trinity County. Thunder potential remains around a 5 to 10 percent chance so it is not represented in the forecast, but this will need to be monitored as it gets closer.

Into the early to middle of next week, high pressure is expected to build back in with inland temperatures warming back into the upper 80s and low 90s and coastal temperatures into the mid to upper 60s. Breezy north winds are expected, along with the potential for offshore flow. And, again, the offshore flow will help keep the coast clearer for the middle of the week. /JLW



AVIATION
VFR and clear skies have prevailed overnight as light offshore winds continue aloft. Satellite imagery is indicating the possibility of a shallow haze layer lurking just offshore early this morning. This may briefly move onshore, with some MVFR haze possibly impacting KACV...otherwise VFR is expected to continue through the day today. Some hires and MOS guidance is indicating a thin layer of fog and coastal stratus developing late tomorrow night and early Saturday.



MARINE
Winds remain mostly northerly through the weekend, weakening overnight and restrengthening to around 10 to 15 kts each afternoon. Northerlies are forecast to strengthen once again late this weekend and early next week, with another round of gales possible around Tuesday. A few small NW and S swells move through the waters over the next week, however seas remain primarily locally generated.
