THE OVERALL MID/UPPER-LEVEL PATTERN SHOULD BECOME QUASI-ZONAL OVER
THE CONUS ON MON...AS A LARGE TROUGH SHIFTS AWAY FROM NEW ENGLAND
AND THE WRN CONUS RIDGE FLATTENS. A CLOSED LOW IN THE SRN STREAM OFF

REMAIN ANCHORED FROM THE MID-ATLANTIC THROUGH THE SRN PLAINS.
...WRN SC/CNTRL GA/CNTRL AL...
A MARGINAL FIRE WEATHER THREAT MAY DEVELOP MON AFTERNOON AS DRYING
CONTINUES AND THE REGION REMAINS ON THE PERIPHERY OF STRONGER
LOW-LEVEL FLOW TO THE S. NELY SURFACE WINDS WILL MAINTAIN
CONTINENTAL TRAJECTORIES AND ENHANCE DRYING. ALTHOUGH TEMPERATURES
WILL ONLY BE NEAR-NORMAL...RH VALUES WILL LIKELY DROP TO NEAR
CRITICAL VALUES /FROM 25 TO 30 PERCENT/. HOWEVER...MODEST SUSTAINED
SURFACE WINDS /AROUND 10 TO 15 MPH/ SHOULD BE THE PRIME MITIGATING
FACTOR TO A CRITICAL THREAT.
