DISCUSSION
SOUTHERLY WINDS OF 15 TO 20 MPH WILL DEVELOP BY THIS AFTERNOON, AND
THIS WILL KEEP A MOIST AIRMASS ACROSS THE AREA TODAY. MINIMUM RH
VALUES WILL ONLY DIP TO AROUND 60 PERCENT. THESE STRONGER WINDS ARE
ASSOCIATED WITH A STRENGTHENING STORM SYSTEM IN THE PLAINS AND
MIDWEST THAT WILL DRIVE A STRONG COLD FRONT THROUGH THE AREA TONIGHT.
THIS FRONT WILL BRING A BRIEF PERIOD OF RAIN TONIGHT, BUT THE
BIGGER IMPACT WITH VERY STRONG NORTHWEST WINDS OF 20 TO 25 MPH
WITH HIGHER GUSTS LATE TONIGHT AND MONDAY. VERY DRY AIR WILL ALSO
MOVE IN, AND THIS WILL PUSH MIMINUM RH VALUES TO 20 TO 30 PERCENT.
THESE ARE CRITICAL CONDITIONS FOR WILDFIRE ACTIVITY AND A FIRE
WEATHER WATCH MAY BE ISSUED LATER TODAY FOR MONDAY. THE DRY AIR
WILL PERSIST ON TUESDAY AND WEDNESDAY, BUT LIGHTER WINDS OF LESS
THAN 10 MPH WILL NOT SUPPORT CRITICAL WILDFIRE CONDITIONS THOSE
DAYS. SOME MOISTURE RECOVERY LATER IN THE WEEK IS EXPECTED AS WINDS
TURN MORE SOUTHERLY. THIS WILL ALLOW MIN RH VALUES TO RISE TO
BETWEEN 40 AND 50 PERCENT.
FOG DEVELOPMENT IS NOT EXPECTED THROUGH TUESDAY.
