AREA FORECAST DISCUSSION National Weather Service Eureka CA 251 PM PDT Wed Apr 17 2024

SYNOPSIS
High pressure continues to build into the region.
Increasing temperatures beneath clearing skies will allow interior valleys to approach or exceed 80 degrees by the end of the week.
Marine stratus is expected to return late this week after the northerlies fully subside and pull away from the coast.
Temperatures will begin cooling this weekend as the high pressure shifts eastward and a shortwave trough approaches the northern portion of the area.



DISCUSSION
A high pressure ridge continues to build into Northwest California, promoting calm weather conditions. Latest GOES-West satellite imagery depicts high level moisture from the central Pacific moving around the ridge and spreading high level clouds across the forecast area; most of the high clouds are moving over Mendocino and Lake counties this afternoon. Warm air advection continues to allow daytime temperatures to climb into the 70s in interior valleys into the end of the week. Coastal temperatures are expected to be slightly warmer compared with yesterday's reading, though breezy northerly winds have redeveloped this afternoon keeping the coast from warming much more than the upper 50s to low 60s. Northwesterly winds will subside this evening.
Some patchy fog may develop very early tomorrow morning, especially around Humboldt Bay; however, weak offshore flow will keep much of the coast free of stratus and fog overnight.

The upper-level heights will continue strengthening across the Northeastern Pacific through tomorrow. Most interior valleys are expected to have temperatures in the mid to upper 70s again.
Additionally, NBM indicates a high chance for temperatures above 80 for many interior valleys of southern Mendocino and Lake counties. The warmest valleys of interior Humboldt, Trinity, and northern Mendocino counties have a slightly lower chance of temperatures above 80. However, all these areas will most likely have highs near or at 80. NBM, also, indicates a high probability of coastal temperatures in the low 60s by tomorrow afternoon.
Limited stratus and fog development, due to the offshore flow overnight tonight, should mean that many coastal areas will be clear long enough to reach into the 60s.

By Friday, ensemble cluster analysis indicates that the high pressure over the Pacific Northwest will begin to break down and shift eastward as an upper level shortwave approaches the area.
The flow will become more zonal which will deepen the marine layer and bring cooler air to the coastal counties. Trinity, eastern Mendocino, and Lake counties are not expected to see much change on Friday.

A weak front will try to push and clip the northern portion of the area this weekend. Light rain or sprinkles are possible for the coastal areas in Del Norte County late Saturday afternoon.
Other than that, mostly mid to high level clouds are expected to stream across the forecast area. Ensembles and deterministic guidance indicate shortwave ridging building over the Pacific Northwest and Northern California by the end of the weekend, before an upper level trough approaches the area.



AVIATION
VFR conditions prevail this afternoon at all terminals.
Northerly winds and a dry, well-mixed boundary layer continue to thwart stratus formation. Though the outlined conditions persist, a weak, southerly eddy may transport sufficient Humboldt Bay moisture for some patchy, shallow and localized stratus/mist formation into Wednesday morning at ACV; however, confidence is low on this scenario. Have no inclusion of a ceiling at ACV, adding a shallow, scattered group with a slight corresponding visibility reduction for the early morning hours. Mid to high clouds increase Thursday.
/JJW



MARINE
The northerly winds will begin a slow weakening trend from south to north this evening through tonight. Steep and hazardous seas up to 12 feet will linger in the outer waters into Thursday morning before a more substantial reduction in both winds and seas takes effect through the remainder of the day tomorrow. The easing of seas and wind will carry into Saturday before a passing front sharply increases the northerlies up to 25 kts in the afternoon. The northerlies look to further increase Sunday with a likely short-lived and transient ridge, followed by weakening into early next weak. /JJW
