   DAY 1 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0302 AM CDT THU AUG 20 2009
   
   VALID 201200Z - 211200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   A STRONG UPPER TROUGH WILL BE CENTERED OVER THE UPPER MS VALLEY AND
   WRN GREAT LAKES LATER TODAY WITH WIDESPREAD PRECIPITATION EXTENDING
   SWD TO THE GULF COAST. TO THE W...AN UPPER RIDGE AXIS WILL REMAIN IN
   PLACE WITH A DEEPENING THERMAL SURFACE TROUGH E OF THE WA/ORE
   CASCADES. MEANWHILE...UPPER LEVEL FLOW WILL BE ON THE INCREASE OVER
   THE PACIFIC NW AS A SHORTWAVE TROUGH GLANCES THE COAST LATE AND
   EJECTS RAPIDLY NEWD INTO B.C. BY FRI MORNING. THIS WAVE WILL BRING A
   SURFACE WIND SHIFT/FRONTAL PASSAGE ACROSS NRN ORE INTO ERN WA LATE.
   VERY WARM AND DRY WEATHER WILL PERSIST UNDER THE RIDGE...ESPECIALLY
   OVER THE GREAT BASIN...WITH ISOLATED DRY THUNDERSTORMS POSSIBLE FROM
   CNTRL ORE INTO ERN WA FROM LATE AFTERNOON INTO THE OVERNIGHT HOURS.
   
   ...CNTRL OREGON INTO ERN WA...
   VERY HOT AND DRY WEATHER WILL EXIST TODAY ACROSS WA/OR AND SW
   ID...AS WELL AS INTO THE GREAT BASIN. HIGH TEMPERATURES WILL EXCEED
   100 F AND MIN RH WILL DROP TO NEAR 10 PERCENT ON AVERAGE.
   MEANWHILE...AN UPPER SHORTWAVE TROUGH WILL APPROACH THE COAST LATE
   IN THE DAY. LOCALLY GUSTY WINDS AROUND 15 MPH ARE EXPECTED ALONG THE
   E SLOPES OF THE CASCADES DURING THE DAY...BUT INCREASING OVERNIGHT
   AS THE WAVE MOVES ACROSS AND A MARINE AIR MASS SURGES E THROUGH THE
   COLUMBIA GORGE WITH GUSTS OF 20-30 MPH AND RISING RH LEVELS. IN
   ADDITION...A VERY SLIGHT CHANCE EXISTS FOR AN ISOLATED DRY
   THUNDERSTORM MAINLY FROM CNTRL OREGON INTO WA LATE DAY AND
   OVERNIGHT. ALTHOUGH FORCING WILL EXIST FOR STORMS...AND LAPSE RATES
   WILL BE FAIRLY STEEP...MOISTURE LEVELS WILL BE QUITE LOW...THUS
   COVERAGE OF STORMS SHOULD BE LITTLE TO NONE.

   DAY 2 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0311 AM CDT THU AUG 20 2009
   
   VALID 211200Z - 221200Z
   
   ...NO CRITICAL AREAS...
   
   ...SYNOPSIS...
   A STRONG UPPER RIDGE WILL BE CENTERED OVER THE ROCKIES WITH
   WIDESPREAD HOT AND DRY WEATHER OVER MOST OF THE WRN U.S...THE
   EXCEPTION BEING WRN WA AND ORE BEHIND A COLD FRONT. THE PRESENCE OF
   AN UPPER TROUGH AND SURFACE CONVERGENCE ALONG THE FRONT WILL LIKELY
   YIELD ISOLATED DRY THUNDERSTORMS FROM ERN OREGON INTO CNTRL ID AND
   WRN MT DURING THE AFTERNOON. GUSTY WLY WINDS WILL EXIST OVER CNTRL
   AND ERN WA BEHIND THE FRONT. ELSEWHERE...A MDT TO HIGH HAINES INDEX
   WILL BE IN PLACE OVER MUCH OF THE GREAT BASIN BUT WINDS WILL BE
   MAINLY LIGHT AND/OR TERRAIN DRIVEN.
   
   ...WA/ORE/ID...
   SUSTAINED WLY WINDS OF 10-15 MPH ARE LIKELY OVER MUCH OF CNTRL AND
   ERN WA...AS WELL AS ORE ON FRI. RH LEVELS WILL ONLY BE MARGINALLY
   LOW OVER WA AND NRN ID DUE TO THE FRONT PASSAGE...BUT LOW VALUES IN
   THE LOWER TEENS WILL EXIST FARTHER S INTO ERN ORE AND SWRN ID. IN
   ADDITION...COOLING ALOFT AND LIFT ASSOCIATED WITH THE UPPER TROUGH
   WILL RESULT IN ISOLATED DRY THUNDERSTORMS FROM ERN ORE INTO WRN MT.
   COVERAGE IS NOT EXPECTED TO LARGE...BUT ANY STORMS THAT DO OCCUR
   WILL HAVE A HIGH LIKELIHOOD OF STARTING FIRES DUE TO SEVERAL DAYS OF
   VERY WARM AND DRY WEATHER.
