   DAY 2 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0349 AM CST MON NOV 28 2005
   
   VALID 291200Z - 301200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   UPPER FLOW ACROSS THE U.S. TURNS MORE ZONAL TUESDAY AS HUDSON BAY
   LOW BECOMES THE DOMINATE LONG WAVE FEATURE OVER NORTH AMERICA. THE
   ACTIVE FIRE WEATHER PATTERN OF THE PAST FEW DAYS SUBSIDES...
   PRIMARILY DUE TO DECREASING LOWER/MID TROPOSPHERIC WINDS ALONG THE
   SOUTHERN TIER. AT THE SURFACE HIGH PRESSURE OVER THE EASTERN PACIFIC
   NUDGES INTO COASTAL CALIFORNIA...TURNING THE FLOW ONSHORE AND
   INCREASING THE HUMIDITY OVER COASTAL SOUTHERN CALIFORNIA.
   
   LOW RH CONDITIONS REMAIN FROM THE COLORADO RIVER VALLEY THROUGH WEST
   TEXAS AS DEWPOINTS HOLD IN THE SINGLE DIGITS/TEENS AND TEMPERATURES
   BEGIN TO MODERATE. FARTHER EAST DRIER AIR REACHES THE GULF COAST
   STATES AS A SURFACE COLD FRONT MOVES OFF THE ATLANTIC COAST LATE IN
   THE DAY. TRAJECTORIES MAINTAIN A BIT OF A SOUTHERLY COMPONENT AND
   MODELS INDICATE RH FROM LOUISIANA TO THE FLORIDA PANHANDLE NEVER
   FALLS BELOW 35 TO 40 PERCENT DESPITE THE COOLER AND DRIER AIR MASS.
