   DAY 1 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0339 AM CDT WED MAY 24 2006
   
   VALID 241200Z - 251200Z
   
   ...CRITICAL FIRE WEATHER AREA FOR CENTRAL AND WRN NEBRASKA...FAR
   SERN WY AND SWRN SD...
   
   ...SYNOPSIS...
   A VERY WARM AND DRY AIR MASS WILL REMAIN FROM SRN CA INTO W TX
   UNDERNEATH UPPER RIDGE...BUT WINDS WILL BE LIGHT. ALONG NRN
   PERIPHERY OF THIS RIDGE...HIGH PRESSURE OVER THE NRN ROCKIES WILL
   COMBINE WITH SURFACE LOW TRANSLATING EWD INTO THE UPPER MS VALLEY TO
   PRODUCE VERY STRONG NWLY WINDS OVER THE NRN PLAINS. LOW RH WILL
   ACCOMPANY THE WINDS FROM ERN MT INTO NEBRASKA. ELSEWHERE...IT WILL
   BE WARM AND DRY ACROSS INTERIOR FL BUT WITH ISOLATED AFTERNOON
   THUNDERSTORMS...WHILE HIGH PRESSURE KEEP RH LEVELS LOW OVER MUCH OF
   THE MID ATLANTIC AND NERN STATES...BUT WITH LIGHT WINDS.
   
   ...CRITICAL FIRE WEATHER AREA - CENTRAL AND WRN NEBRASKA...FAR SERN
   WY AND SWRN SD...
   
   PRIMARY CONDITIONS: VERY STRONG WINDS / LOW RH / WARM TEMPERATURES
   
   VERTICALLY STACKED LOW PRESSURE SYSTEM WILL TRANSLATE EWD OUT OF THE
   DAKOTAS AND INTO MN DURING THE DAY. HIGH PRESSURE WILL BUILD IN
   QUICKLY BEHIND THIS LOW...AND WILL CAUSE VERY STRONG WINDS TO OCCUR.
   SUSTAINED NWLY WINDS OF 20-30 MPH WILL BE LIKELY...WITH GUSTS OF
   30-50 MPH ACROSS NRN NEBRASKA INTO SD. RH LEVELS WILL DROP AS DEEP
   MIXING OCCURS...WITH VALUES INTO THE TEENS DURING PEAK HEATING.
   ALTHOUGH SOME GREENUP IS OCCURRING...CRITICAL CONDITIONS WILL STILL
   MATERIALIZE ESPECIALLY IN AREAS WHERE FINE FUEL LOADINGS ARE
   HEAVIEST.
   
   ...ERN MT INTO WRN DAKOTAS / ERN NEB...
   WINDS WILL BE VERY STRONG OUT OF THE NW AT OVER 30 MPH WITH HIGHER
   GUSTS...ALTHOUGH RH LEVELS WILL NOT BE AS LOW AS FARTHER SW WITH
   25-35 PERCENT TYPICAL. IN ADDITION...RAIN WAS FALLING OVER MUCH OF
   THE AREA AS OF EARLY MORNING...THUS THREAT WILL BE MITIGATED DUE TO
   ADDED MOISTURE.

   DAY 2 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0423 AM CDT WED MAY 24 2006
   
   VALID 251200Z - 261200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   A VERY HOT AND DRY AIR MASS WILL REMAIN ACROSS THE DESERT SW AND
   FOUR CORNERS STATES UNDER A STRONG UPPER RIDGE. PRESENCE OF WEAK
   UPPER DISTURBANCE MOVING INTO THE LOWER CO RIVER VALLEY REGION WILL
   BRING A SLIGHT INCREASE IN WINDS FOR A MARGINAL FIRE WEATHER THREAT.
   FARTHER NE...ISOLATED DRY THUNDERSTORMS WILL BE LIKELY OVER THE HIGH
   TERRAIN OF CENTRAL AND SRN CO.
   
   ...MUCH OF AZ AND NM...SRN CO AND UT...
   FIRE THREAT WILL CONTINUE TO INCREASE THROUGH THE PERIOD DUE TO
   PERSISTENT HOT AND DRY WEATHER...AS WELL AS INCREASING INSTABILITY.
   HOT TEMPERATURES AND DRY AIR MASS WILL CAUSE A HIGH HAINES IN MANY
   AREAS LATE IN THE DAY...WHEN RH LEVELS WILL BE LOWEST AND IN THE
   SINGLE DIGITS AND LOWER TEENS. IN ADDITION...A WEAK UPPER
   DISTURBANCE WILL HELP WEAKEN THE WRN EDGE OF THE RIDGE A BIT...AND
   WILL CAUSE AN INCREASE IN WINDS ALOFT. THESE WINDS WILL MIX EASILY
   TO THE SURFACE...AVERAGING 10-15 KTS WITH HIGHER GUSTS. VERY HOT AND
   DRY AIRMASS COMBINED WITH VERY DRY FUELS WILL PROVIDE AN ENVIRONMENT
   FAVORABLE FOR FIRE STARTS THURSDAY. IT SHOULD BE NOTED THAT GIVEN
   HIGH HAINES...VERY LOW RH...AND VERY DRY FUELS...DEGREE OF FIRE
   THREAT WILL BE HIGHLY DEPENDENT ON WIND FORECAST.
   
   ...SRN CO INTO NRN NM...
   AT LEAST ISOLATED DRY THUNDER IS LIKELY LATE THU WITH VERY WARM
   TEMPERATURES AND STEEP LAPSE RATES. GENERAL SLY FLOW REGIME WILL
   CAUSE CONVECTION TO DEVELOP ALONG THE CO FRONT RANGE AS WELL AS OVER
   CENTRAL CO MTNS. DEVELOPMENT MAY EXTEND SWD INTO FAR NRN NM AS
   WELL...IF ENOUGH MOISTURE EXISTS. HIGHEST THREAT OF FIRE STARTS WILL
   BE OVER THE SRN HALF OF THE STATE OF CO AND POINTS SOUTH WHERE FUELS
   ARE DRIEST. FORECAST COVERAGE OF LIGHTNING IS TOO LOW FOR A CRITICAL
   DRY THUNDER AREA AT THIS TIME...BUT CONFIDENCE IN EXACT AREA AND
   STORM CONCENTRATION WILL BE MUCH HIGHER IN NEXT DAY 1 FORECAST.
   
   ...CNTRL NEB...
   STRONG WINDS WILL CONTINUE ACROSS THE MO VALLEY BEHIND UPPER LOW
   MOVING THROUGH THE GREAT LAKES. SUSTAINED NWLY WINDS OF 20-30 MPH
   WILL STILL BE LIKELY...ALTHOUGH RH LEVELS WILL PROBABLY NOT DIP
   BELOW 20-25 PERCENT AT PEAK HEATING. THIS...COMBINED WITH RECENT
   PRECIPITATION...WILL HELP MITIGATE FIRE THREAT.
