   DAY 1 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   1129 AM CDT THU JUN 30 2016

   VALID 301700Z - 011200Z

   THE PREVIOUS FORECAST FOR ISOLATED DRY THUNDERSTORMS ACROSS PARTS OF
   THE GREAT BASIN AND NORTHERN ROCKIES...AND ELEVATED WIND-DRIVEN FIRE
   WEATHER CONDITIONS FOR PARTS OF ORE/WA...LARGELY REMAINS ON TRACK.
   THE ONLY CHANGE MADE WAS TO ADJUST THE ISOLATED DRY THUNDERSTORM
   RISK AREA ACROSS FAR SERN ORE AND NV...TO BETTER ALIGN WITH LATEST
   OBSERVATIONAL AND MODEL TRENDS. BOTH WATER VAPOR AND OBSERVED
   SOUNDINGS SHOW RELATIVELY RICH MIDLEVEL MOISTURE AMIDST DRY
   LOW-LEVELS...ALONG THE NRN FRINGE OF MONSOONAL MOISTURE OVER THE
   SOUTHWEST. THIS WILL SUPPORT THE DEVELOPMENT OF ISOLATED TO WIDELY
   SCATTERED THUNDERSTORMS THIS AFTERNOON...WITH THERMODYNAMIC PROFILES
   REMAINING FAVORABLE FOR LIGHT PRECIPITATION TOTALS AND GUSTY/ERRATIC
   OUTFLOW WINDS.

   ..ROGERS.. 06/30/2016

   .PREV DISCUSSION... /ISSUED 0331 AM CDT THU JUN 30 2016/

   ...SYNOPSIS...
   MID-LEVEL RIDGING ACROSS THE WEST WILL CONTINUE TO WEAKEN...AS A
   PAIR OF WEAK IMPULSES PROGRESS FARTHER INLAND. ONE WILL TRANSLATE
   EASTWARD FROM BRITISH COLUMBIA TO ALBERTA...WHILE ANOTHER WILL
   SLOWLY SETTLE SOUTHWARD OVER NORTHERN CALIFORNIA. MEANWHILE...BROAD
   CYCLONIC FLOW ACROSS THE EASTERN CONUS WILL BE REINFORCED BY A SHARP
   SHORTWAVE TROUGH ADVANCING FROM THE NORTHERN PLAINS TO THE GREAT
   LAKES REGION.

   ...PORTIONS OF THE GREAT BASIN AND NORTHERN ROCKIES...
   WITH WEAK FORCING FOR ASCENT DUE TO THE AFOREMENTIONED
   IMPULSES...SUFFICIENT MOISTURE /ON THE NORTHWEST FRINGE OF DEEPER
   MONSOONAL MOISTURE/ WILL SUPPORT THUNDERSTORM DEVELOPMENT ONCE AGAIN
   THIS AFTERNOON. SIMILAR TO PREVIOUS DAYS...PW VALUES ON THE ORDER OF
   0.5-0.8 INCHES AND DEEPLY MIXED SUB-CLOUD LAYERS WILL FAVOR POCKETS
   OF THUNDERSTORMS WITH LIGHT PRECIPITATION CORES. THE COMBINATION OF
   LIGHTNING STRIKES AND GUSTY OUTFLOW WINDS WILL ENCOURAGE NEW FIRE
   STARTS AND ERRATIC BEHAVIOR.

   ...INTERIOR PACIFIC NORTHWEST...
   IN RESPONSE TO THE BRITISH COLUMBIA IMPULSE...A MODEST INCREASE IN
   WESTERLY MID-LEVEL FLOW WILL MATERIALIZE OVER THE REGION.
   CONCURRENTLY...OFFSHORE SFC RIDGING AND A TROUGH IN THE LEE OF THE
   CASCADES /AIDED BY CROSS-TERRAIN FLOW/ WILL ENHANCE THE SFC PRESSURE
   GRADIENT SUCH THAT POCKETS OF BREEZY CONDITIONS DEVELOP IN THE
   CASCADE GAPS AND WESTERN PARTS OF THE COLUMBIA BASIN. DOWNSLOPE
   DRYING WILL SUPPORT RH VALUES DROPPING INTO THE TEENS AND 20S
   THROUGH THE DAY...RESULTING IN ELEVATED FIRE-WEATHER CONCERNS.
