DISCUSSION
ONE MORE NIGHT OF WARM AND MOIST CONDITIONS IS EXPECTED HEADING INTO
SATURDAY MORNING. THE FRONT WILL BRING SCATTERED TO NUMEROUS SHOWERS
AND THUNDERSTORMS TO THE REGION SATURDAY EVENING AND OVERNIGHT
BEFORE PUSHING OFF TO THE SOUTH BY SUNDAY MORNING. BREEZY NORTHERLY
WINDS DEVELOP BEHIND THE FRONT, BRINGING A COOLER AND MUCH DRIER
AIRMASS INTO THE AREA. ELEVATED FIRE WEATHER CONCERNS MAY DEVELOP
FOR SUNDAY AFTERNOON, WITH 10-15 KT NORTHEAST WINDS AND AFTERNOON RH
FALLING TO 25-35 PERCENT. THIS DRY AIR REMAINS IN PLACE FOR MONDAY,
BUT FIRE CONCERNS WILL BE LESSER AS WINDS WILL BE LIGHTER, AROUND 5-
10 KT. FLOW SHIFTS TO THE SOUTHEAST STARTING TUESDAY, WHICH WILL
INCREASE MOISTURE OVER THE AREA AND MITIGATE FIRE WEATHER CONCERNS
THROUGH THE REMAINDER OF THE FORECAST PERIOD.
