KEY MESSAGES

-Northerly winds are much lighter, but will be breezy in the afternoons.

-Generally clear skies and dry conditions, even along shore, through the week.

-Conditions will warm through Thursday with highs in the interior peaking near 90.

DISCUSSION

Northerly winds have subsided substantially since what was experienced over the weekend. Winds will generally turn breezy in the afternoons this week. Overnight lows will be on the chilly side again tonight, but will begin moderating this week with building high pressure. Some areas of localized frost will be possible in the Hayfork and Larabee Valley Tuesday morning.

Conditions will remain very dry with warming temperatures through the week. Highs will most likely top out around 90 for the interior on Thursday. This will constitute only a minor HeatRisk for this time of year. Hotter temperatures will help reform a marine inversion and will increase chances for coastal stratus and fog.

AVIATION

Northerly winds eased for a few hours from 12z to 18z at KCEC and have returned with gusts up to 25kts and will continue into the evening as NBM shows up to 30kts of gusts possible before sunset. LAMP guidance suggests northerlies backing off around 05z tonight for KCEC. KACV has had recent northerly wind gusts up to 24kts and sustained winds 14-16kts, these are expected to be easing by 06z and veering southerly overnight 5kts or below. There could be a few hours of LIFR/IFR around 15-16z Tuesday. Northerly winds gusting at KUKI have been intermittent since 18z, LAMP guidance suggests northerlies with sustained winds below 10kts after 03z. Despite gusty winds, there is not much of a signal for LLWS as the model soundings do not show the threshold for velocity or direction meeting the criteria for wind shear. /EYS

MARINE

The pressure gradient relaxes slightly and the strongest winds move farther off the coast as the high pressure builds in. However, a large area of gale force gusts around 34-45 kts expected across all zones, with the strongest winds downwind of Cape Mendocino. Steep to very steep, hazardous seas will continue with the elevated winds. Conditions will remain hazardous across the waters for much of the work week with strong to gale force gusts north winds and steep to very steep seas. Gale force winds and very steep seas are forecast to persists across the outer waters through Friday. /ZVS
