.DISCUSSION...
A COLD FRONT WILL MOVE THROUGH THE AREA EARLY TONIGHT AND WILL
BRING IN COOLER AIR AND INCREASING HUMIDITY TO THE FIRE SITE. THE
LOW LEVEL MOISTURE IS LAGGING BEHIND THE FRONT AND POOR RH
RECOVERIES ARE EXPECTED TONIGHT. RH'S WILL RISE INTO THE MID 20
PERCENT RANGE MY MIDDAY SUNDAY. WINDS WILL BE NORTH SUNDAY AND
SUNDAY NIGHT WITH A BRIEF PERIOD OF WIND GUSTS TO 20 MPH DURING
THE AFTERNOON. A FEW ISOLATED SHOWERS WILL ALSO BE POSSIBLE
SUNDAY. A DRY NORTHWEST FLOW OF AIR WILL SET UP ACROSS THE AREA
SUNDAY NIGHT AND WILL CONTINUE THROUGH MONDAY. THIS WILL ALLOW
MINIMUM RH'S TO FALL INTO THE LOWER 20 PERCENT RANGE MONDAY
AFTERNOON WITH COOLER DAYTIME TEMPERATURES ALSO CONTINUING. LOOK
FOR A HAINES INDEX OF 3 ON SUNDAY AND SLIGHTLY HIGHER ON MONDAY
WITH A 4.
