AREA FORECAST DISCUSSION National Weather Service Eureka CA 259 PM PDT Mon Jun 1 2020

SYNOPSIS. Isolated showers are expected for the interior today and a few lightning strikes will be possible this afternoon and evening over Trinity, northeast Mendocino, and northern Lake counties. Otherwise, dry weather and above normal temperatures are expected for much of the week. Significant cooling and rain showers are expected for the weekend.

DISCUSSION. A mid to upper-level wave continues to slowly move across the area, with visible imagery showing some cumulus developing over inland areas. Decent to good instability for the area will allow for some thunder chances this afternoon and evening over portions of Trinity, northeast Mendocino, eastern Humboldt, and northern Lake counties. Spotty showers will also be possible across Trinity, portions of interior Mendocino, eastern Humboldt, northern Lake, and eastern Del Norte counties this afternoon and evening. Shower activity should quickly taper off by late this evening.

High pressure will nose into the region starting on Tuesday and allow dry weather to take hold through most of Friday. Temperatures will once again be on the increase starting Tuesday across the interior. Wednesday is forecast to be the warmest day and we'll continue to monitor the situation in case a Heat Advisory may be needed for portions of Lake County. Highs across portions of the interior will range from the mid 80s to mid 90s across some the warmer interior valleys on Wednesday. Ensemble and deterministic guidance show an upper-level trough approaching from the northwest late in the work week and into the weekend. Showers may start as early as late Friday afternoon across the northern part of the forecast area. Snow levels will be lower with this next system, forecast to hover around 5,550 to 6,000 feet. Portions of the higher elevations in Trinity County may see some snow this weekend! That being said, moisture will be somewhat lacking with this system and the highest rainfall totals overall will be in the northern part of the area. Areas in Mendocino, Lake and southern Trinity counties may struggle to see any precipitation. Highest totals will be in the more favorable west facing slopes of Del Norte County.

AVIATION. Weather in the next 24 hours at airports/airfields will be influenced by offshore building high pressure . and expanding heat troughing from the south. Interaction between the two pressure systems may trigger a few breezy winds at CEC and ACV. This morning pockets of marine stratus continued to lurk near the coast allowing for brief periods of IFR skies even occurring in the early afternoon. Airstrips over the interior mountain areas . and notably in Trinity County today will probably experience some convective activity this afternoon as enough instability and moisture continues over these areas. /TA

MARINE. North to northwest winds will range from mostly 15 to 25 knots across the outer waters and around Cape Mendocino and Point Saint George through early Friday morning. Small Craft Advisories are in place for these breezy winds and building short-period seas across the outer waters. Some areas of steep seas may propagate into the inner waters, so went ahead and issued Small Crafts for both inner zones. Buoy data seems to support this. Some gusts to around Gale Force will be possible in the outer waters starting around the middle of the week, but overall coverage appears to be lacking at this time. A mid-period northwest swell will diminish today and a longer-period southwest swell will linger throughout portions of the waters through the middle of the week. Otherwise, another another mid-period northwest swell will move through waters on Wednesday.

EKA WATCHES/WARNINGS/ADVISORIES. CA . None. NORTHWEST CALIFORNIA COASTAL WATERS . Small Craft Advisory until 9 PM PDT Tuesday for PZZ450-455.

Small Craft Advisory until 3 AM PDT Friday for PZZ470-475.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
