   DAY 1 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0323 AM CDT MON MAR 30 2015

   VALID 301200Z - 311200Z

   ...SYNOPSIS...
   06Z SATELLITE IMAGERY DEPICTS A SHORTWAVE TROUGH MOVING EWD INTO THE
   LOWER GREAT LAKES. THIS SHORTWAVE IS EXPECTED TO CONTINUE EWD
   THROUGH THE NORTHEAST STATES...MOVING OFFSHORE AROUND 03Z/TUE.
   ANOTHER SHORTWAVE TROUGH WILL FOLLOW IN THE WAKE OF THE
   FIRST...MOVING SEWD FROM SRN MANITOBA ACROSS THE UPPER MIDWEST AND
   UPPER GREAT LAKES. UPPER RIDGING -- INITIALLY EXTENDING FROM NRN CA
   THROUGH THE PACIFIC NW AND INTO BRITISH COLUMBIA -- WILL MOVE EWD
   ACROSS THE NRN ROCKIES WHILE AMPLIFYING IN RESPONSE TO A SHORTWAVE
   TROUGH MOVING INTO THE PACIFIC NW. AT THE SURFACE...A LOW ASSOCIATED
   WITH THE MANITOBA SHORTWAVE TROUGH WILL MOVE THROUGH THE NRN PLAINS
   AND UPPER MIDWEST WHILE HIGH PRESSURE SHIFTS EWD ACROSS THE
   SOUTHEAST. RESULTANT INCREASE IN THE PRESSURE GRADIENT ACROSS THE
   PLAINS IS EXPECTED TO RESULT IN SOME ENHANCED SURFACE WINDS. 

   ...SRN HIGH PLAINS...CNTRL PLAINS...MID MO VALLEY...
   ABOVE-AVERAGE TEMPERATURES ARE EXPECTED ACROSS THE PLAINS AND MID MO
   VALLEY AS DOWNSLOPE EFFECTS RESULT IN A DEEPLY MIXED ENVIRONMENT
   WITH HIGHS GENERALLY IN THE MID TO UPPER 70S. MIN RH VALUES WILL
   RANGE FROM THE MID TEENS ACROSS THE CNTRL HIGH PLAINS TO NEAR 25
   PERCENT IN IA. THE CNTRL HIGH PLAINS WILL BE WITHIN THE BASE OF THE
   SURFACE PRESSURE TROUGH...RESULTING IN WEAK WINDS AND A SOMEWHAT
   TEMPERED FIRE WEATHER THREAT. SWLY WINDS ARE ANTICIPATED ACROSS
   AREAS FROM THE SRN HIGH PLAINS NEWD INTO IA. THERE WILL LIKELY BE
   SOME DISSOCIATION BETWEEN THE WARMEST TEMPERATURES/LOWEST RH VALUES
   -- AROUND 15 PERCENT ACROSS THE TX PANHANDLE -- AND THE STRONGEST
   WINDS -- NEAR 20 MPH ACROSS IA -- WITHIN THIS REGION. ELEVATED TO
   LOCALLY CRITICAL FIRE WEATHER CONDITIONS ARE STILL LIKELY BUT THE
   DISSOCIATION OF THE STRONGEST WINDS AND DRIEST CONDITIONS WILL KEEP
   THE LIKELIHOOD OF CRITICAL CONDITIONS TOO LOW TO DELINEATE A THREAT
   AREA WITH THIS FORECAST. 

   IN CONTRAST TO AREAS FARTHER S...SURFACE PRESSURE TROUGH WILL BE
   LOCATED E OF THE MID MO VALLEY BY THE AFTERNOON...RESULTING IN NWLY
   WINDS. DOWNSLOPE EFFECTS ARE STILL EXPECTED WITH THE COMBINATION OF
   DEEP BOUNDARY LAYER MIXING...A TIGHT SURFACE PRESSURE GRADIENT...AND
   AT LEAST MODEST MID/UPPER LEVEL SUPPORT AIDING IN THE DEVELOPMENT OF
   SUSTAINED NWLY WINDS AROUND 20 MPH. THESE WINDS AMIDST WARM
   TEMPERATURES AND RH VALUES NEAR 20 PERCENT WILL SUPPORT ELEVATED TO
   LOCALLY CRITICAL FIRE WEATHER CONDITIONS.
