   VALID 031200Z - 041200Z
   
   ...CRITICAL FIRE WEATHER AREA FOR A PORTION OF THE NRN HIGH
   PLAINS...
   
   ...SYNOPSIS...
   A STRONG UPPER TROUGH OVER THE GULF OF ALASKA WILL MOVE SEWD INTO
   THE PAC NW THROUGH THE PERIOD. AHEAD OF THIS UPPER TROUGH...MID
   LEVEL FLOW WILL STRENGTHEN OVER THE PAC NW/NRN GREAT BASIN AND THE
   NRN ROCKIES. THIS WILL SUPPORT AN INCREASE IN SFC WINDS FROM THE
   GREAT BASIN NEWD INTO THE NRN PLAINS. DRY CONTINENTAL AIR COMBINED
   WITH WARM TEMPERATURES AND MODERATE WINDS WILL PRODUCE A CRITICAL
   FIRE WEATHER THREAT OVER THE NRN HIGH PLAINS TODAY. SLIGHTLY WEAKER
   WINDS AND/OR HIGHER RH READINGS WILL PRECLUDE CRITICAL FIRE WEATHER
   CONDITIONS FURTHER SW OVER THE CENTRAL ROCKIES/GREAT BASIN. WARM
   TEMPERATURES WILL REMAIN OVER THE SRN/ERN HALF OF THE NATION UNDER
   THE PRESENCE OF A STRONG UPPER RIDGE...BUT LIGHT WINDS WILL PRECLUDE
   ANY CRITICAL FIRE WEATHER THREAT IN THIS REGION.
   
   ...CRITICAL FIRE WEATHER AREA - A PORTION OF NRN HIGH PLAINS...
   
   PRIMARY CONDITIONS: SUSTAINED SSWLY WINDS FROM 20-25 MPH...MIN RH
   READINGS FROM 15-20 PERCENT.
   
   AHEAD OF A STRONG SEWD MOVING UPPER TROUGH OVER THE GULF OF
   ALASKA...A STRONG MID/UPPER LEVEL JET WILL DEVELOP OVER THE PAC
   NW/NRN ROCKIES THROUGH TONIGHT. WARM/DRY CONDITIONS WILL EXIST SOUTH
   OF A SFC FRONTAL BOUNDARY EXTENDING ACROSS THE NRN ROCKIES/PAC NW.
   AN OVERLAP OF THE STRONGEST MID LEVEL WINDS/WARM SFC TEMPERATURES
   WILL EXIST OVER THE NRN HIGH PLAINS OF WRN SD/WRN NEB AND ERN WY
   THIS AFTERNOON. IN THIS REGION...SSWLY WINDS FROM 20-25 MPH AIDED BY
   STEEP LAPSE RATES AND TRANSFER OF STRONGER WINDS ALOFT...WILL
   COMBINE WITH MIN RH READINGS FROM 15-20 PERCENT TO PRODUCE A
   CRITICAL FIRE WEATHER THREAT.
   
   ...GREAT BASIN/CENTRAL ROCKIES...
   A GREATER DISPLACEMENT WILL EXIST BETWEEN THE STRONGER MID LEVEL
   FLOW AND WARM/DRY CONDITIONS OVER THE GREAT BASIN. THIS SHOULD
   RESULT IN SUSTAINED SFC WIND GENERALLY REMAINING BELOW 20 MPH. OVER
   THE CENTRAL ROCKIES...STRONGER SFC WINDS WILL BE MITIGATED BY HIGHER
   RH READINGS PRECLUDING ANY CRITICAL FIRE WEATHER THREAT.

   DAY 2 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK

   VALID 041200Z - 051200Z
   
   ...CRITICAL FIRE WEATHER AREA FOR A PORTION OF THE SRN GREAT
   BASIN/LOWER CO RIVER VALLEY...
   
   ...SYNOPSIS...
   THE STRONG UPPER TROUGH OVER THE PAC NW AT THE START OF THE PERIOD
   WILL DIG SEWD ALONG THE WEST COAST AND INTO GREAT BASIN BY THE END
   OF THE PERIOD. ASSOCIATED WITH THIS STRONG UPPER TROUGH...SFC WINDS
   WILL INCREASE OVER THE SRN GREAT BASIN/LOWER CO RIVER VALLEY.
   COMBINED WITH LOW RH READINGS...A CRITICAL FIRE WEATHER THREAT WILL
   DEVELOP OVER THE AREA DURING THE AFTERNOON. A STRONG UPPER RIDGE
   WILL REMAIN IN CONTROL OVER MUCH OF THE ERN HALF OF THE
   NATION...SUPPORTING WELL ABOVE NORMAL TEMPERATURES AND LOWER RH
   READINGS. HOWEVER LIGHT WINDS WILL PRECLUDE ANY CRITICAL FIRE
   WEATHER CONDITIONS IN THIS REGION.
   
   ...CRITICAL FIRE WEATHER AREA - A PORTION OF THE SRN GREAT
   BASIN/LOWER CO RIVER VALLEY...
   
   PRIMARY CONDITIONS: SUSTAINED SSWLY WINDS FROM 20-25 MPH...MIN RH
   READINGS FROM 10-15 PERCENT
   
   STRENGTHENING MID LEVEL WIND FIELDS WILL OCCUR IN ASSOCIATION WITH A
   STRONG UPPER TROUGH APPROACHING THE REGION. WARM TEMPERATURES WILL
   COMBINE WITH SEASONABLY LOW DWPTS TO PRODUCE LOW RH READINGS AROUND
   15 PERCENT. STEEP LAPSE RATES IN THE LOWER-MID LVLS WILL SUPPORT
   TRANSFER OF STRONG WIND FIELDS ALOFT TO THE SFC...LEADING TO
   CRITICALLY STRONG SFC WINDS DEVELOPING BY THE AFTERNOON.
