   VALID 251200Z - 261200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   LARGE-SCALE PATTERN WILL DE-AMPLIFY WITH STRONGER MID-LEVEL WLYS
   BECOMING MORE ZONAL AND CONFINED TO THE NRN CONUS. THIS WILL HELP
   MAINTAIN A SLOW WEAKENING OF THE EXPANSIVE LOW/MID-LEVEL ANTICYCLONE
   CENTERED ACROSS THE CAROLINAS/SRN APPALACHIANS. MEANWHILE...A
   VIGOROUS IMPULSE AND ASSOCIATED LOW/MID-LEVEL CYCLONE WILL TRACK
   SLOWLY EWD ACROSS THE NRN ROCKIES ONTO THE NRN PLAINS BY SAT
   MORNING.
   
   ...W-CNTRL FL...
   DESPITE A GRADUAL RELAXING OF THE SURFACE PRESSURE
   GRADIENT...SUSTAINED ELY WINDS OF 15 TO 20 MPH APPEAR LIKELY BENEATH
   A 25 TO 30 MPH LOW-LEVEL JET. AFTERNOON TEMPERATURES WILL REMAIN
   WARM /MIDDLE 80S/ WITH AT LEAST PARTIAL INSOLATION...TEMPERED
   SOMEWHAT BY INCREASED BOUNDARY LAYER CU COMPARED TO THE PAST FEW
   DAYS. IR SATELLITE IMAGERY INDICATES SUBSTANTIAL UPSTREAM LOW-LEVEL
   CLOUDINESS BEING ADVECTED WWD FROM THE WRN ATLANTIC BASIN. THIS
   SHOULD RESULT IN MARGINAL RH VALUES THIS AFTERNOON AND THUS NO
   LONGER WARRANTING A CRITICAL AREA AS IN THE PAST FEW DAYS. POCKETS
   OF RH NEAR 35 PERCENT SHOULD DEVELOP WHERE THE GREATEST DAYTIME
   HEATING CAN OCCUR...LEADING TO LOCALIZED/RELATIVELY BRIEF CRITICAL
   CONDITIONS. 
   
   ...S-CNTRL WY...
   STRONG MID-LEVEL WINDS /FROM 45 TO 55 MPH AT 500 MB/ WILL DEVELOP
   THIS AFTERNOON AS A SHORT WAVE TROUGH CROSSES MT/NRN WY. STEEP
   LOW-LEVEL LAPSE RATES WILL PROMOTE DEEP MIXING AND SHOULD RESULT IN
   SUSTAINED WLY SURFACE WINDS FROM 20 TO 30 MPH. ALTHOUGH TEMPERATURES
   WILL WARM CLOSER TO NORMAL /THROUGH THE 60S/...RH VALUES SHOULD
   REMAIN MARGINAL /AROUND 15 TO 20 PERCENT/.
