   VALID 061200Z - 071200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   STRONG WESTERLY FLOW ALOFT WILL RESIDE ACROSS THE NWRN AND N CENTRAL
   STATES ON FRIDAY...WHILE A WEAK UPPER LEVEL CLOSED LOW MIGRATES EWD
   ACROSS THE BAJA PENINSULA. FARTHER E...AN UPPER LEVEL TROUGH IS
   FORECAST TO PROGRESS EWD INTO THE ATLANTIC...WITH SURFACE HIGH
   PRESSURE TRAILING THE TROUGH AND BECOMING SITUATED ALONG THE
   ATLANTIC COAST. THIS AREA OF HIGH PRESSURE IS EXPECTED TO MAINTAIN A
   DRY CONTINENTAL AIRMASS ACROSS PORTIONS OF SRN MS/AL/GA AND THE FL
   PANHANDLE.
   
   ...SRN MS/AL/GA AND THE FL PANHANDLE...
   OBSERVED SURFACE AND RAOB DATA OVER THE SERN STATES INDICATES A VERY
   DRY AIRMASS WAS IN PLACE ACROSS THE REGION THURSDAY
   AFTERNOON/EVENING...WITH MINIMUM RH IN THE 30S AND PWAT VALUES AOB
   0.25 INCHES. AS AN UPPER TROUGH SHIFTS EAST INTO THE
   ATLANTIC...CONFLUENT MID LEVEL FLOW BEHIND THE TROUGH IS FORECAST TO
   BECOME POSITIONED ALONG THE ATLANTIC COAST. THIS WILL FAVOR SURFACE
   HIGH PRESSURE SHIFTING TOWARD THE COAST AS WELL...WITH LOW LEVEL
   WINDS BECOMING ELY DURING THE AFTERNOON. THESE WINDS WILL CONTINUE
   TO MAINTAIN THE DRY CONTINENTAL AIRMASS OVER SRN MS/AL/GA AND THE FL
   PANHANDLE DURING FRIDAY...WITH MIN RH VALUES FALLING THROUGH THE 30S
   ONCE AGAIN. HOWEVER...A CRITICAL OUTLOOK AREA WILL NOT BE ASSIGNED
   DUE TO A WEAK SURFACE PRESSURE GRADIENT AND LOW POTENTIAL FOR
   SIGNIFICANT GUSTS THROUGH THE AFTERNOON.
   
   ...NRN MT...
   A S/W TROUGH WAS OBSERVED IN WV IMAGERY ENTERING THE PAC NW COAST
   EARLY FRIDAY MORNING...AND IT IS FORECAST TO MOVE ACROSS NRN MT BY
   MID AFTERNOON. STRONG WLY FLOW ALOFT WILL ACCOMPANY THE PASSING
   TROUGH...AND WHEN COMBINED WITH FAVORABLE BOUNDARY LAYER
   MIXING...WILL PROMOTE WIND GUSTS POSSIBLY AS HIGH AS 50 MPH OVER
   PORTIONS OF NRN MT. HOWEVER...THE LOW LEVEL AIRMASS IS FORECAST TO
   REMAIN RATHER COOL...AND RH VALUES ARE CURRENTLY NOT EXPECTED TO
   FALL TO CRITICAL LEVELS...WHICH WILL PRECLUDE AN OUTLOOK AREA FROM
   BEING ASSIGNED.
