Weather High pressure offshore and over Northern CA will
produce another warm and dry day today.
Locally gusty N-NE winds will diminish around midday. A strong low pressure system will drop from
the Eastern Gulf of Alaska into the Pacific Northwest on Tuesday as the high
pressure moves off to the south and east.
Gusty westerly winds and increasing mid and high clouds will reach far
Northern CA tonight and the remainder of the North Ops region by Tuesday
morning. Colder air will move into far
Northern CA by late Tuesday and winds will gradually diminish. There is a daily chance of light rain showers
late Tuesday through early Friday, with snow above 5000-6000’. Slightly warmer and sunnier conditions are
expected late Friday and Saturday, except for a slight chance of afternoon
showers or thunderstorms in the mountains on Saturday.
Fuels/Fire Potential
Live fuels across much of North Ops are in some phase of greenup. Some are near peak values unseasonably early while a few others are already starting to cure. Most annual grasses below about 2500 ft have cured.
Gusty westerly winds may slightly increase fire danger east of the Cascade-Sierra Tuesday, but recent rains and the current state of greenup will limit the effects of the high winds. The weather system moving in from the north beginning Tuesday will also bring higher RH values to all PSAs and some light precipitation can be expected in the far north. These conditions will keep significant fire potential relatively low through Day 7.
