..DISCUSSION FROM SFOFWFMTR
...ELEVATED FIRE WEATHER CONCERNS ACROSS THE INTERIOR BAY AREA
AND CENTRAL COAST THROUGH FRIDAY DUE TO LOW HUMIDITIES...
A SHALLOW MARINE LAYER REMAINS IN PLACE RESULTING IN COOLER AND
MORE HUMID CONDITIONS NEAR THE COAST. AREAS ACROSS THE INTERIOR
AND HIGHER TERRAIN WILL REMAIN VERY DRY THROUGH FRIDAY.
ADDITIONALLY, AN AFTERNOON ONSHORE PUSH OF STRONGER WINDS WILL
IMPACT INLAND VALLEYS AND PASSES. THE MEMORIAL DAY WEEKEND WILL
FEATURE MORE WIDESPREAD COOLING AND A DEEPENING MARINE LAYER WITH
NIGHT AND MORNING LOW CLOUDS AND FOG.
..DISCUSSION FROM SFOFWFEKA
HEAT PEAKS TODAY ACROSS THE INTERIOR WITH HIGH TEMPERATURES
CLIMBING INTO MID 90S. CONDITIONS WILL REMAIN VERY DRY WITH RH
BETWEEN 20 AND 30 PERCENT. ASIDE FROM SOME MODERATE NORTH BREEZES
ALONG SHORE, WINDS WILL BE GENTLE AND TERRAIN DRIVEN WITH FEW
GUSTS EVEN REACHING 10 MPH. CONDITIONS WILL EASE THIS WEEKEND WITH
MORE MARINE INFLUENCE PUSHING INLAND. A WEAK SHORTWAVE
DISTURBANCE WILL BRING UP TO A 10 PERCENT CHANCE FOR AN ISOLATED
THUNDERSTORM OVER EASTERN TRINITY COUNTY FRIDAY AFTERNOON.
