   DAY 2 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0214 PM CDT SUN MAR 28 2010
   
   VALID 291200Z - 301200Z
   
   ...NO CRITICAL AREAS...
   
   ONGOING FORECAST IS IN FAIRLY GOOD SHAPE. LATEST 12Z MODELS STILL
   INDICATE VERY DRY CONDITIONS ACROSS SWRN PORTIONS OF THE CONUS. SWLY
   FLOW WILL INCREASE AS A STRONG LOW PRESSURE SYSTEM BEGINS TO DROP
   INTO THE PAC NW CREATING A LARGE AREA OF GUSTY SFC WINDS FROM THE
   GREAT BASIN NE INTO THE NRN HIGH PLAINS.
   
   ...NERN WY AND WRN SD...
   A LEE TROF WILL DEVELOP FROM NERN MT TO SW TX AS THE UPPER LEVEL
   RIDGE BREAKS DOWN. A THERMAL RIDGE LOCATED FROM SW TX INTO THE NRN
   PLAINS WILL ALLOW TEMPERATURES TO REACH INTO THE 60S. SWLY SFC FLOW
   WILL BE ENHANCED BY DOWNSLOPE OFF HIGHER TERRAIN TO THE W AND GUSTS
   TO AROUND 35 MPH WILL BE POSSIBLE. HOWEVER...RH VALUES WILL BE
   MARGINAL IN THE 20 TO 30 PERCENT RANGE.
   
   ..STOPPKOTTE.. 03/28/2010
   
   .PREV DISCUSSION... /ISSUED 0236 AM CDT SUN MAR 28 2010/
   
   ...SYNOPSIS...
   A LEE PRESSURE TROUGH WILL DEEPEN ACROSS THE HIGH PLAINS OF THE
   CNTRL U.S. ON MONDAY...AS THE UPPER RIDGE FLATTENS AND A LARGE
   TROUGH SPREADS EWD ACROSS THE PACIFIC NW AND WRN GREAT BASIN. WINDY
   CONDITIONS WILL MATERIALIZE AS A RESULT ACROSS MT...WY...AND INTO
   WRN NEB AND SD. VERY WINDY CONDITIONS WILL ALSO EXIST WWD INTO THE
   NRN GREAT BASIN AND PACIFIC NW...BUT WITH COOLER TEMPERATURES AND
   HIGHER MOISTURE LEVELS.  
   
   ...ERN NM...WRN TX...
   AN EXTREMELY DRY AIR MASS WILL EXIST MONDAY AFTERNOON WITH RH
   DROPPING INTO THE SINGLE DIGITS AND LOWER TEENS AS TEMPERATURES RISE
   INTO THE 70S AND 80S. VERY STEEP LOW LEVEL LAPSE RATES WILL ALSO
   EXIST FOR AN UNSTABLE ATMOSPHERE. SLY WINDS WILL INCREASE TO AROUND
   15 MPH SUSTAINED BUT HIGHER GUSTS ARE LIKELY AS THE LEE TROUGH
   DEEPENS.
   
   ...WRN NV...
   A COLD FRONT IS LIKELY TO STRETCH ACROSS THE NRN GREAT BASIN AS AN
   UPPER TROUGH AND VERY STRONG WINDS SPREAD OVERHEAD. DOWNSLOPE E OF
   THE SIERRA MTNS SHOULD YIELD VERY STRONG WIND GUSTS IN EXCESS OF 40
   MPH. HIGH TEMPERATURES MAY REACH THE LOW 70S...WHICH WOULD SUGGEST
   MIN RH NEAR 15 PERCENT.
