   DAY 1 FIRE WEATHER OUTLOOK

   VALID 111200Z - 121200Z
   
   ...CRITICAL FIRE WEATHER AREA FOR A PORTION OF THE SRN PLAINS...
   
   ...SYNOPSIS...
   AN UPPER SYSTEM WILL MOVE NEWD FROM THE SRN ROCKIES INTO THE GREAT
   LAKES TODAY. IN THE WAKE OF THIS SYSTEM...MODERATE WLY WINDS WILL
   OCCUR BEHIND A DRYLINE OVER THE SRN HIGH PLAINS. LOW RH READINGS
   WILL ACCOMPANY THE WINDS SUPPORTING ANOTHER DAY OF CRITICAL FIRE
   WEATHER CONDITIONS TO THIS REGION. BREEZY SLY WINDS WILL OCCUR
   ACROSS MOST OF THE REMAINDER OF THE CENTRAL U.S...BUT RH READINGS
   WILL BE TOO HIGH TO PRODUCE ANY ADDITIONAL CRITICAL FIRE WEATHER
   THREAT AREAS. FURTHER EAST...HIGH PRESSURE WILL REMAIN OVER THE ERN
   SEABOARD...PROVIDING FOR DRY AIR AND GENERALLY LIGHT WINDS FOR MUCH
   OF THE NATION EAST OF THE APPALACHIANS. AGAIN THE EXCEPTION TO THIS
   WILL BE OVER FLA...WHERE SUSTAINED NELY WINDS WILL AVERAGE 10-15 MPH
   WITH GUSTS OVER 20 MPH. HOWEVER DEWPTS WITH THE ONSHORE FLOW WILL BE
   HIGHER THAN AREAS FURTHER NORTH...LIMITING ANY CRITICAL FIRE WEATHER
   THREAT AS WELL.
   
   ...CRITICAL FIRE WEATHER AREA 1 - MUCH OF ERN NM....WRN TX/WRN OK/OK
   PANHANDLE...SERN CO/SWRN KS...
   
   PRIMARY CONDITIONS: SUSTAINED SWLY WINDS FROM 20-25 MPH WITH GUSTS
   OVER 35 MPH...MIN RH READINGS FROM 10-20 PERCENT...LONG TERM DROUGHT
   
   AHEAD OF A WEAK COLD FRONT...AND BEHIND A UPPER LEVEL TROUGH/SFC
   DRYLINE...DEWPTS GENERALLY IN THE 20S/30S AND TEMPERATURES IN THE
   UPPER 70S TO 80S WILL PRODUCE MIN RH READINGS FROM 10-20 PERCENT.
   PROXIMITY OF A MODERATE LOW LEVEL JET...MID LEVEL COOLING AND STEEP
   LAPSE RATES ASSOCIATED WITH UPPER TROUGH PASSAGE WILL SUPPORT
   MODERATE SUSTAINED WSWLY WINDS FROM 20-30 MPH WITH GUSTS OVER 35
   MPH. THE STRONGEST WINDS ARE ANTICIPATED ALONG THE LOW LEVEL JET
   AXIS FROM THE NRN TX PANHANDLE NEW INTO SWRN KS. WITH THE NEWD
   MOVEMENT OF THE UPPER SYSTEM...THE DRYLINE SHOULD MIX INTO WRN OK
   ALLOWING FOR CRITICAL CONDITIONS TO DEVELOP INTO THIS AREA DURING
   THE MID-LATE AFTERNOON. FURTHER EAST...LOW LEVEL MOISTURE WILL
   INCREASE EAST OF THE DRYLINE LIMITING CRITICAL FIRE WEATHER
   CONDITIONS OVER CENTRAL/ERN OK AND SCENTRAL KS. WINDS WILL DIMINISH
   AFTER SUNSET AS THE PRESSURE GRADIENT RELAXES AND WITH APPROACH OF A
   WEAK SURFACE FRONT.
   
   ...SERN STATES...
   A BROAD AREA OF MIN RH READINGS FROM 25-35 PERCENT WILL EXIST TODAY
   AS DRY AIR REMAINS OVER THE AREA IN PROXIMITY TO A LARGE SFC HIGH
   PRESSURE AREA OFF THE MID-ATLANTIC COAST. SUSTAINED WINDS MAY
   BRIEFLY EXCEED CRITICAL THRESHOLDS /15 MPH/ FOR AN HR OR TWO DURING
   THE AFTERNOON...BUT GENERALLY LIGHT WINDS WILL PRECLUDE A CRITICAL
   FIRE WEATHER AREA.
   
   ...MID-ATLANTIC NWD INTO NRN NEW ENGLAND...
   AS IN THE SE...THE AREA WILL RESIDE UNDER THE INFLUENCE OF A BROAD
   SFC HIGH PRESSURE AREA CENTERED OFF THE MID-ATLANTIC. ABOVE NORMAL
   TEMPERATURES IN THE 60S/70S ALONG WITH DWPTS IN THE 30S WILL PRODUCE
   MIN RH READINGS FROM 25-35 PERCENT. GENERALLY LIGHT WINDS /LESS THAN
   10 MPH/ WILL PRECLUDE A CRITICAL FIRE WEATHER THREAT.
   
   ...CENTRAL/ERN OK AND SCENTRAL KS...
   EAST OF THE DRYLINE /WHICH IS FCST TO MOVE TO THE POSITION OF U.S
   HWY 183 BY THE LATE-AFTERNOON/ STRONG SLY LOW LEVEL WINDS WILL
   EXIST. WITH DEWPTS IN THE 50S AND TEMPERATURES IN THE 70S /LIKELY
   COOLER THAN YESTERDAY DUE TO THE COPIOUS MID-HIGH CLOUD COVER
   ASSOCIATED WITH UPPER SYSTEM MOVING OUT OF THE SWRN STATES/ MIN RH
   READINGS WILL LIKELY NOT FALL BELOW 40 PERCENT. THIS WILL PRECLUDE A
   CRITICAL FIRE WEATHER THREAT. HOWEVER WINDS GUSTY OVER 35 MPH WILL
   CREATE HIGH FIRE DANGER. 
   
   ...REMAINDER OF ERN CO/WRN KS AND SWRN NEB...
   BEHIND A WEAK COLD FRONT...WINDS WILL SHIFT NWLY EARLY IN THE DAY.
   BEING NORTH OF THE LOW LEVEL JET...AND RELATIVELY WEAK PRESSURE
   RISES...SUSTAINED NWLY WINDS LESS THAN 20 MPH SHOULD OCCUR FOR THE
   MAJORITY OF THE DAY. MILD TEMPERATURES IN THE UPPER 60S-MID 70S WILL
   KEEP RH READINGS AROUND 15 PERCENT. IN ADDITION...ISOLATED MAINLY
   DRY TSTMS WILL BE POSSIBLE DURING THE AFTERNOON.

   DAY 2 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   1221 AM CDT TUE APR 11 2006
   
   VALID 121200Z - 131200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   AHEAD OF AN UPPER TROUGH THAT WILL MOVE FROM THE PLAINS INTO THE
   GREAT LAKES THROUGH THE PERIOD...SSWLY WINDS WILL INCREASE OVER THE
   ERN GREAT LAKES AND MUCH OF NEW ENGLAND. ALTHOUGH TEMPERATURES WILL
   BE ABOVE NORMAL IN THE 60S TO 70S...INCREASING MOISTURE SHOULD
   OFFSET THE WARMING AND KEEP MIN RH READINGS ABOVE 30 PERCENT. IN
   ADDITION...SCT PRECIPITATION WILL BE POSSIBLE/LIKELY OVER MUCH OF
   THE REGION DURING THE AFTERNOON HRS. THUS CRITICAL FIRE WEATHER
   CONDITIONS ARE NOT ANTICIPATED TO OCCUR OVER THIS REGION. IN THE
   WAKE OF A DEPARTING UPPER TROUGH...UPPER RIDGING WILL BUILD OVER THE
   ROCKIES/PLAINS STATES. WHERE THE SFC PRESSURE GRADIENT WILL BE
   STRONGEST /OVER THE NRN PLAINS AND THE GREAT LAKES/ MIN RH READINGS
   WILL APPROACH OR EXCEED CRITICAL LEVELS FROM MN INTO NRN WI /25-35
   PERCENT/. HOWEVER WETTING RAINS EXPECTED OVER THE AREA TODAY WILL
   LIMIT THE CRITICAL FIRE WEATHER THREAT. GENERALLY LIGHT WINDS ARE
   EXPECTED THE REMAINDER OF THE HIGH PLAINS/SWRN STATES WHERE RH
   READINGS WILL AGAIN BE LOW.
   
   ...NEW ENGLAND...
   INCREASING SFC SWLY WINDS FROM 20-25 MPH WILL OCCUR AHEAD OF AN
   UPPER TROUGH THAT WILL MOVE EWD ACROSS THE GREAT LAKES DURING THE
   PERIOD AS THE PRESSURE GRADIENT INTENSIFIES. WHERE THE WINDS ARE
   FCST TO BE STRONGEST...NRN/ERN NY AND VT...CLOUD COVER WILL INCREASE
   DURING THE AFTERNOON /WITH THE CHANCE OF RAIN BY LATE AFTERNOON/.
   THIS SHOULD INCREASE RH READINGS DURING THIS PERIOD. THUS CRITICAL
   FIRE WEATHER CONDITIONS MAY OCCUR FOR POSSIBLY A COUPLE HR PERIOD
   AROUND MIDDAY...NOT SUFFICIENT FOR AN OUTLOOK AREA.
   
   ...SERN/MID ATLANTIC STATES...
   ALTHOUGH LOW LEVEL MOISTURE WILL INCREASE SLOWLY BETWEEN TODAY AND
   TOMORROW...RH READINGS ARE STILL ANTICIPATED TO BE LOW /30-35
   PERCENT/. HOWEVER...UNLIKE FURTHER NORTH WINDS ARE NOT EXPECTED TO
   GET ABOVE 15 MPH.
   
   ...SRN GREAT BASIN/FOUR CORNERS AND SRN HIGH PLAINS...
   SWLY WINDS WILL INCREASE TO BETWEEN 10-20 MPH OVER THE SRN HIGH
   PLAINS/SRN ROCKIES TO BETWEEN 20-30 MPH OVER THE SRN GREAT BASIN.
   MIN RH READINGS WILL BE LOWEST WHERE THE WINDS ARE WEAKEST...WITH
   MIN RH READINGS EXPECTED TO BETWEEN 15-25 PERCENT OVER THE SRN GREAT
   BASIN/LOWER COLORADO RIVER VALLEY. THUS NO CRITICAL FIRE WEATHER
   CONDITIONS ARE ANTICIPATED.
