   DAY 1 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   0211 AM CDT TUE JUL 07 2015

   VALID 071200Z - 081200Z

   ...SYNOPSIS...
   A SHORTWAVE IMPULSE ROTATING SOUTH/SOUTHEAST FROM THE LARGER-SCALE
   TROUGH CENTERED OVER CENTRAL CANADA WILL MOVE ACROSS PARTS OF THE
   NORTHERN ROCKIES THIS AFTERNOON. AS A RESULT...WEAK WESTERLY DEEP
   LAYER FLOW WILL CONTINUE OVER THE COLUMBIA BASIN WHERE ELEVATED FIRE
   WEATHER CONCERNS WILL PREVAIL. FURTHERMORE...FALLING HEIGHTS AND
   ADEQUATE MIDLEVEL MOISTURE COULD RESULT IN ISOLATED THUNDERSTORMS
   NEAR THE INTERNATIONAL BORDER FROM NORTHEAST WA INTO FAR NORTHWEST
   MT. TO THE SOUTHWEST...THE UPPER LOW OFF THE NORTHERN CA COAST WILL
   SLOWLY SHIFT SOUTHEAST TOWARD THE CENTRAL CA COAST BY 12Z WEDNESDAY.
   ABUNDANT MIDLEVEL MOISTURE REMAINS ACROSS THE GREAT BASIN INTO PARTS
   OF THE PACIFIC NORTHWEST AND ANOTHER DAY OF ISOLATED TO WIDELY
   SCATTERED THUNDERSTORMS WILL BE POSSIBLE. 

   ...SOUTHERN ORE INTO FAR NORTHWEST MT...

   ANOTHER DAY OF ISOLATED TO SCATTERED THUNDERSTORMS IS EXPECTED
   ACROSS PARTS OF SOUTHERN ORE. WHILE PW VALUES REMAIN IN THE
   0.75-1.00 INCH RANGE...LEADING TO WETTING THUNDERSTORM RAIN
   CORES...LIGHTNING STRIKES OUTSIDE THE MAIN THUNDERSTORM CORES WILL
   POSE A RISK FOR NEW STARTS GIVEN LITTLE TO NO RAINFALL AND DRY
   FUELS. FURTHER NORTH FROM NORTHEAST WA INTO FAR NORTHWEST
   MT...ISOLATED THUNDERSTORMS WILL BE POSSIBLE AS A SHORTWAVE IMPULSE
   TRACKS SOUTHEAST ACROSS THE REGION. PW VALUES HERE ARE FORECAST TO
   BE AROUND 0.85 INCHES...WITH GENERALLY SLOW STORM MOTION EXPECTED.
   AS A RESULT...WETTING RAINS WILL BE POSSIBLE. HOWEVER...AS IS THE
   CASE FURTHER SOUTH...DRY FUELS COMBINED WITH LIGHTING STRIKES
   OUTSIDE THE MAIN RAIN CORES WILL POSE A THREAT FOR NEW FIRE STARTS. 


   ACROSS THE SOUTHERN COLUMBIA BASIN/COLUMBIA GORGE REGION...WESTERLY
   DEEP LAYER FLOW WILL LEAD TO DRY DOWNSLOPE WINDS. VERY WARM
   TEMPERATURES AND RH VALUES FALLING INTO THE TEENS ARE
   EXPECTED...WITH THE MAIN LIMITING FACTOR BEING WIND SPEEDS...WHICH
   WILL GENERALLY BE LIGHT AT 10-15 MPH WITH OCCASIONAL GUSTS NEAR 20
   MPH.
