..DISCUSSION FROM SFOFWFMTR
A MUCH WETTER PATTERN ARRIVES FRIDAY WITH WIDESPREAD RAIN EXPECTED
THROUGH NEXT WEEK. THE FIRST ROUND ARRIVES TO THE NORTH BAY FRIDAY
WITH AROUND 1/2" TO 1" EXPECTED. A SERIES OF ATMOSPHERIC RIVERS
WILL THEN BRING MORE WIDESPREAD RAIN STARTING SATURDAY AND
PERSISTING THROUGH THE WEEK. SEVERAL INCHES OF RAIN ARE EXPECTED
ACROSS THE STATE. WHILE HIGH WINDS ARE EXPECTED AT TIMES, AND THERE
IS A SLIGHT CHANCE FOR THUNDERSTORMS, THE LARGE AMOUNT OF RAIN AND
HIGH HUMIDITY WILL ALLEVIATE ANY FIRE WEATHER CONCERNS.
..DISCUSSION FROM SFOFWFEKA
ANOTHER STORM SYSTEM WILL BEGIN TO APPROACH THE AREA THURSDAY.
SOUTHERLY WINDS WILL TURN BREEZY BY THURSDAY EVENING STRONGEST OVER
THE HUMBOLDT AND DEL NORTE RIDGES. 1 TO 3 INCHES OF RAIN IS MOST
LIKELY TO QUICKLY FALL THROUGH FRIDAY MORNING. THE NEXT CHANCE FOR
HEAVY RAIN AND STRONG WINDS WILL ARRIVE FOR THE LATTER PORTION OF
THE WEEKEND, MOST LIKELY FOCUSED ON THE SOUTHERN HALF OF THE AREA.
