KEY MESSAGES

* Generally mild, seasonable weather is expected for the next week.

SYNOPSIS

Dry, seasonable weather is likely for the next week. Slightly warmer interior temperatures are expected today and Monday before another trough brings cooler temperatures next week. Coastal stratus is likely to clear this afternoon but may be more persistent early next week.

DISCUSSION

Weak high pressure rebuilds over the area today bringing slightly warmer temperatures this afternoon for the interior. Most interior areas will see highs in the 90s with a stray triple digit possible for the warmest valleys. A deep marine layer continues to bring stratus deep inland into the river valleys, however high pressure will make this slightly shallower than previous days. Breezy coastal winds this afternoon are likely to scatter any remaining stratus bringing a mostly clear, but breezy, Sunday afternoon at the coast with 60s and possibly near 70s possible for the immediate coast.

Monday through the middle of the week, a trough starts to approach the area bringing slightly cooler interior temperatures along with a deeper marine layer. Light winds offshore may lead to coastal stratus to be persistent into the afternoons. Moisture and instability is limited with this troughing pattern, which will limit thunderstorm potential. Generally mild, seasonable weather is likely for much of the next week.

AVIATION

Stratus has rebuilt over the coastal areas. A shallow LIFR ceiling is being observed along the coastal waters with a more elevated IFR to MVFR stratus later also being observed over Humboldt County. LIFR to IFR stratus is likely to continue through the night and scatter and lift shortly after sunrise. VFR conditions are likely by late morning across the area.

MARINE

Northerly winds continue to increase today, especially in the northern outer waters and in the lee of Cape Mendocino. Wind gusts peak at 25 to 30 kts across these areas, but localized gale force gusts are possible in the lee of Cape Mendocino. While winds nearshore remain light, with peak gusts of 10 to 15 kts, steep seas of 6 to 8 ft are likely to propagate nearshore. Winds and seas diminish Monday as a frontal boundary arrives to the area. Conditions are likely to remain mild through Wednesday afternoon.
