   ...SYNOPSIS...
   MUCH OF THE SRN THIRD OF THE CONUS WILL EXPERIENCE LOW RH THIS
   AFTERNOON AS SURFACE RIDGING REMAINS ANCHORED ALONG THE GULF COAST
   AND ERN GREAT BASIN. A BROAD UPPER-LEVEL TROUGH WILL BE MAINTAINED
   ACROSS THE ERN HALF OF THE NATION AS ONE SIGNIFICANT IMPULSE LIFTS
   NEWD FROM NRN NEW ENGLAND AND A SECONDARY IMPULSE DIVES SWD INTO THE
   UPPER MIDWEST.
   
   ...PORTIONS OF THE SRN CA COASTAL RANGE...
   09Z SUBJECTIVE SURFACE MESOANALYSIS PLACES A TROUGH ALONG THE SRN CA
   COAST WITH HIGH PRESSURE CENTERED OVER CNTRL NV AND NERN UT. 
   DESPITE WEAK MID/UPPER-LEVEL WINDS DUE TO MID/UPPER-LEVEL
   RIDGING...A MODEST SURFACE PRESSURE GRADIENT WILL AID IN LOCALIZED
   GUSTY N/NELY WINDS ACROSS FAVORED CANYONS/PASSES FROM THE SANTA YNEZ
   TO THE SAN BERNARDINO MTNS...YIELDING POOR RH RECOVERY THIS MORNING.
   THE PRESENCE OF THE RIDGING ALOFT OVER THE PAST FEW DAYS WILL
   CULMINATE IN WELL-ABOVE AVERAGE TEMPERATURES THIS AFTERNOON ACROSS
   INTERIOR SWRN CA. THUS...A LONG DURATION OF CRITICALLY LOW RH /FROM
   5 TO 15 PERCENT/ IS ANTICIPATED ALONG AND ADJACENT TO THE COASTAL
   MTNS INTO THIS EVENING. ALTHOUGH A NOCTURNAL INCREASE IN WINDS IS
   EXPECTED TONIGHT...A COINCIDENT SURGE IN RICHER LOW-LEVEL MOISTURE
   WILL ALSO OCCUR FROM CNTRL CA IMPROVING RH RECOVERY WED MORNING.
   
   ...SOUTHEAST...
   WITH SURFACE DEW POINTS CURRENTLY IN THE TEENS/20S FROM THE
   CAROLINAS SWWD INTO MS AND NRN FL...WIDESPREAD CRITICALLY LOW RH
   /FROM 15 TO 30 PERCENT/ WILL OCCUR THIS AFTERNOON AS TEMPERATURES
   WARM INTO THE MID 50S TO MID 60S. SUSTAINED SURFACE WINDS WILL BE
   LIGHTER COMPARED TO MONDAY /GENERALLY FROM 6 TO 12 MPH/...OWING TO
   THE PROXIMITY OF SURFACE RIDGING CENTERED ALONG THE GULF COAST.
   
   ...ERN CO/FAR WRN KS...
   DRY CONDITIONS WILL CONTINUE ALONG THE LEE OF THE CNTRL/SRN ROCKIES
   AS TEMPERATURES WARM BACK INTO THE MIDDLE 60S TO LOWER 70S. RH
   VALUES WILL LIKELY DROP TO AROUND 10 TO 15 PERCENT. W/NWLY WINDS
   SHOULD LARGELY REMAIN MODERATE /FROM 12 TO 20 MPH/...BUT MAY BRIEFLY
   INCREASE BEHIND A SURFACE TROUGH PUSHING SEWD ACROSS THE CNTRL
   PLAINS.

   NWS STORM PREDICTION CENTER NORMAN OK

   VALID 051200Z - 061200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   BROAD CYCLONIC FLOW IN THE UPPER-LEVELS WILL ENCOMPASS MUCH OF THE
   CONUS BY EARLY THU AS A SIGNIFICANT SHORT WAVE TROUGH AMPLIFIES SEWD
   FROM THE UPPER MIDWEST THROUGH THE NORTHEAST/MID-ATLANTIC...AND AS
   AN UPSTREAM IMPULSE DIGS FROM THE PACIFIC NW TO THE NRN/CNTRL
   ROCKIES. FIRE WEATHER CONCERNS SHOULD BE MINIMAL ACROSS MUCH OF THE
   SRN CONUS WITH GENERALLY LIGHT WINDS AND/OR INCREASING RH...EXCEPT
   FOR PORTIONS OF THE SOUTHEAST.
   
   ...CNTRL/ERN GA THROUGH SERN NC...
   W/SWLY LOW-LEVEL FLOW WILL INCREASE OUT AHEAD OF LOW PRESSURE
   CROSSING THE OH RIVER VALLEY AND MID-ATLANTIC STATES THROUGH WED
   EVENING. ALTHOUGH THIS WILL HELP GRADUALLY MOISTEN THE BOUNDARY
   LAYER...THE ANTECEDENT DRY AIR MASS SHOULD BE SUFFICIENT FOR ANOTHER
   AFTERNOON OF CRITICALLY LOW RH. WITH TEMPERATURES GENERALLY WARMING
   INTO THE 60S...RH VALUES WILL LIKELY DROP TO AROUND 20 TO 30
   PERCENT. SUSTAINED SURFACE WIND SPEEDS WILL BE STRONGER COMPARED TO
   TUESDAY...GENERALLY FROM 12 TO 20 MPH. THIS WILL LEAD TO AN ENHANCED
   FIRE WEATHER THREAT GIVEN PREVALENT LONG-TERM DROUGHT.
