KEY MESSAGES

- Rain on Monday for the North Coast, with the highest amounts north of Cape Mendocino.

- Much warmer weather next week into the weekend.

- Elevated fire weather conditions in Lake County with low afternoon relative humidity and gusty winds Wednesday through Thursday.

SYNOPSIS

Rain will return to the North Coast Monday with the greatest amounts north of Cape Mendocino in Humboldt and Del Norte counties. Dry conditions will return starting on Tuesday with hot temperatures expected across the interior Wednesday into next weekend.

LONG TERM

(Friday through Monday) Upper level ridging is expected to continue to build over the West Coast Friday into the weekend. As the ridge builds the thermal trough may approach the coast over the weekend allowing temperatures to warm at the coast. Depending on coastal cloudiness and any southerly surges of stratus, coastal areas could be quite warm Friday and Saturday with highs approaching the 70 degree mark. Interior areas will likely cap out around 100 degrees with 850 temperatures never really warming too much more through the weekend.

AVIATION

A storm system will bring rain to ACV and CEC today with ceilings falling into IFR and possibly LIFR as the day progresses. Rain will be moderate at times with gusty south winds in excess of 20 kt at CEC. Farther south and inland rain is expected to be lighter but ceilings will also fall across much of the area into MVFR or lower, except maybe in Lake County. Conditions will improve gradually overnight but abundant moisture along the Humboldt and Del Norte coastlines could leave low ceilings and reduced visibilities into Tuesday morning.

MARINE

Northerly winds will decrease overnight and become southerly as a storm system approaches the area. South winds will briefly exceed small craft criteria during the day on Monday in the northern zones with a few gusts to near gale possible. Winds will be brief enough that the steep seas won't have much time to build considerably. Thus, only a brief period of small craft winds and seas are expected Monday into Monday evening. The front will shift through the area Monday evening leaving high pressure to rebuild over the eastern Pacific and a thermal trough to build over interior California. This will result in increasing northerlies once again and a return to small craft north winds and seas Tuesday into Wednesday and possible gales late in the week.
