   DAY 1 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   1136 AM CDT WED JUL 27 2016

   VALID 271700Z - 281200Z

   ...PORTIONS OF THE NORTHERN ROCKIES...
   AN ISOLATED DRY-THUNDER AREA IS INTRODUCED FOR PORTIONS OF
   NORTHWESTERN WY...NORTHEASTERN ID...AND SOUTHWESTERN MT. WATER-VAPOR
   IMAGERY IDENTIFIES A MID-LEVEL IMPULSE CURRENTLY TRANSLATING
   EASTWARD ACROSS NORTHERN ORE/SOUTHERN WA...AND THIS IMPULSE SHOULD
   REACH THE NORTHERN ROCKIES BY LATE AFTERNOON INTO THIS EVENING. AS A
   RESULT...MODEST FORCING FOR ASCENT AND HEATING ON HIGHER TERRAIN
   SHOULD ENCOURAGE ISOLATED CONVECTION LATER TODAY.

   12Z BOI AND RIW RAOBS SAMPLED PW AROUND 0.6-0.75 INCHES...AND
   FORECAST SOUNDINGS SUGGEST SUFFICIENT MID-LEVEL BUOYANCY AND A
   DEEPLY MIXED BOUNDARY LAYER WILL LIKELY MATERIALIZE ACROSS THE
   HIGHLIGHTED AREA. THIS THERMODYNAMIC ENVIRONMENT WILL BE FAVORABLE
   FOR A FEW DRY-LIGHTNING STRIKES. MOREOVER...THE FIRE-WEATHER THREAT
   WILL BE FURTHER EXACERBATED BY QUICK STORM MOTIONS AND DOWNWARD
   TRANSPORT OF STRONGER WINDS ALOFT...RESULTING IN LITTLE WETTING RAIN
   AND GUSTY/ERRATIC OUTFLOW WINDS.

   ..PICCA.. 07/27/2016

   .PREV DISCUSSION... /ISSUED 0200 AM CDT WED JUL 27 2016/

   ...SYNOPSIS...
   A MID-LEVEL ANTICYCLONE WILL REMAIN CENTERED OVER THE GREAT BASIN
   TODAY. MODESTLY ENHANCED WLY/NWLY MID-LEVEL FLOW WILL CONTINUE OVER
   THE PACIFIC NORTHWEST...NRN/CNTRL ROCKIES...AND ADJACENT HIGH
   PLAINS. HOT/DRY CONDITIONS ARE EXPECTED UNDERNEATH THE ANTICYCLONE
   ACROSS MUCH OF THE GREAT BASIN AND SURROUNDING AREAS.
   BUT...LOW-LEVEL WINDS ARE EXPECTED TO REMAIN GENERALLY WEAK WHERE RH
   VALUES WILL BECOME LOWERED.

   ISOLATED TO SCATTERED THUNDERSTORMS WILL ONCE AGAIN BE POSSIBLE
   ACROSS PORTIONS OF THE SOUTHWEST IN ASSOCIATION WITH MONSOONAL
   MOISTURE. PWAT VALUES ACROSS THIS REGION ARE EXPECTED TO GENERALLY
   REMAIN AOA 1 INCH...AND WETTING RAINFALL SHOULD OCCUR WITH MOST
   THUNDERSTORMS. FURTHER N ACROSS PARTS OF THE NRN/CNTRL
   ROCKIES...ISOLATED TO WIDELY SCATTERED THUNDERSTORMS SHOULD FORM
   THIS AFTERNOON IN HIGHER TERRAIN ALONG THE PERIPHERY OF THE
   ANTICYCLONE. PWAT VALUES ARE FORECAST TO BE MARGINALLY SUPPORTIVE
   FOR ISOLATED DRY THUNDERSTORMS ACROSS A NARROW CORRIDOR OF ERN
   ID...SWRN MT...AND WRN/CNTRL WY. BUT...MID-LEVEL WINDS SHOULD REMAIN
   RELATIVELY WEAK...AND ANY CONVECTION THAT FORMS SHOULD MOVE EWD INTO
   A MORE MOIST LOW-LEVEL AIRMASS WITH AN INCREASING CHANCE FOR WETTING
   RAINFALL. HAVE THEREFORE NOT INTRODUCED AN ISOLATED DRY THUNDERSTORM
   AREA.
