..DISCUSSION FROM SFOFWFMTR
NEAR TO SLIGHTLY BELOW NORMAL TEMPERATURES, A DEEP MARINE LAYER WITH
A CHANCE FOR DRIZZLE, AND AN INCREASE IN DIURNAL WINDS ARE ON TAP
FOR TODAY. AN UPPER-LEVEL LOW IS BRINGING HIGH CLOUDS AND ELEVATED
RAIN SHOWERS TO THE AREA, FORTUNATELY THERE IS A LOW PROBABILITY OF
THUNDERSTORMS WITH LITTLE TO NO RAINFALL EXPECTED TO REACH THE
GROUND. WARMING AND DRYING TREND KICKS OFF TUESDAY AND CONTINUES
THROUGH THURSDAY. ABOVE NORMAL TEMPERATURES, DRY CONDITIONS, AND A
COMPRESSED MARINE LAYER ARE EXPECTED AS A RESULT. RELATIVE HUMIDITY
AND RECOVERY WILL BE POOR TO MODERATE FOR MOST WITH NOCTURNAL DRYING
LIKELY ABOVE THE MARINE LAYER. DIURNAL WINDS WILL PREVAIL WITH LIGHT
OFFSHORE FLOW POSSIBLE DURING THE OVERNIGHT PERIODS.
..DISCUSSION FROM SFOFWFEKA
HIGH PRESSURE OVER THE PACIFIC NORTHWEST WILL MAINTAIN WARM, DRY
WEATHER ACROSS INTERIOR VALLEYS THROUGH MONDAY WITH ZERO CHANCE OF
WETTING RAIN. INTERIOR HIGHS WILL CONTINUE REACH THE LOW 90S WITH RH
AROUND 20 PERCENT. DAYTIME WINDS WILL REMAIN GENTLE AND TERRAIN
DRIVEN. LIGHT OFFSHORE WINDS WITH AN EASTERLY COMPONENT WILL
DEVELOP TUESDAY NIGHT INTO WEDNESDAY MORNING AS LOW PRESSURE SYSTEM
MOVES OVERHEAD. THIS LOW WILL ALSO COOL CONDITIONS SLIGHTLY MID
WEEK AND PULL IN MORE MARINE INFLUENCE.
