   DAY 1 FIRE WEATHER OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   1016 AM CDT THU JUL 28 2016

   VALID 281700Z - 291200Z

   ...PORTIONS OF THE SOUTHERN GREAT BASIN AND CENTRAL SIERRA...
   THE ISOLATED DRY-THUNDER AREA IS EXPANDED WESTWARD TO THE CENTRAL
   SIERRA NEVADA...WHERE SUFFICIENT MID-LEVEL MOISTURE WILL COMBINE
   WITH TERRAIN-INDUCED CIRCULATIONS TO FOSTER A FEW STORMS LATER
   TODAY. SIMILAR TO POINTS EAST WITHIN THE OUTLINED AREA...STORM
   MOTIONS SHOULD BE MODEST AT BEST. HOWEVER...A FAVORABLE
   THERMODYNAMIC ENVIRONMENT WILL EXIST ATOP VERY DRY
   FUELS...SUPPORTIVE OF LIGHTNING-INDUCED FIRE STARTS.

   ELSEWHERE...THE ELEVATED AREA ACROSS SOUTHWESTERN WY AND VICINITY
   REMAINS UNCHANGED...WITH BREEZY/DRY CONDITIONS EXPECTED TO
   MATERIALIZE LATER TODAY.

   ..PICCA.. 07/28/2016

   .PREV DISCUSSION... /ISSUED 0213 AM CDT THU JUL 28 2016/

   ...SYNOPSIS...
   ...PORTIONS OF THE GREAT BASIN AND CENTRAL ROCKIES...

   AN UPPER LEVEL ANTICYCLONE WILL REMAIN OVER THE SOUTHWESTERN DESERTS
   TODAY...WITH WEST/NORTHWESTERLY DEEP LAYER FLOW EXTENDING FROM THE
   PACIFIC NORTHWEST TO THE CENTRAL ROCKIES/ADJACENT HIGH PLAINS. AN
   EMBEDDED BELT OF ENHANCED NORTHWESTERLY FLOW WILL OVERSPREAD
   NORTHERN PORTIONS OF THE GREAT BASIN TO THE CENTRAL ROCKIES AS A
   WEAK IMPULSE TRAVERSES THE REGION. THIS WILL RESULT IN
   WEST/NORTHWESTERLY SURFACE WINDS AROUND 15 MPH WITH SOME HIGHER
   GUSTS ACROSS PARTS OF FAR SOUTHEAST ID/NORTHEAST UT INTO SOUTHWEST
   WY. DOWNSLOPE FLOW WILL AID IN DRYING AND AS TEMPERATURES CLIMB INTO
   THE MID 80S TO NEAR 100 DEGREES IN LOWER ELEVATIONS...RH VALUES WILL
   FALL INTO THE 12-15 PERCENT RANGE. WHILE IT SEEMS UNLIKELY...SHOULD
   WIND SPEEDS TREND HIGHER...AN UPGRADE TO CRITICAL MAY BE NEEDED
   LATER TODAY.  

   ADDITIONAL FIRE WEATHER CONCERNS WILL EXIST OVER A SMALL PART OF
   SOUTHEAST NV INTO SOUTHWEST/SOUTH-CENTRAL UT WHERE ISOLATED DRY
   THUNDERSTORMS WILL BE POSSIBLE. THIS AREA WILL BE ON THE FRINGES OF
   HIGHER PW TO THE SOUTH AND EAST. STORM MOTION WILL BE SLOW BUT PW
   VALUES LESS THAN 0.65 INCHES AND DEEP/DRY SUB-CLOUD LAYER WILL
   PRECLUDE MUCH IN THE WAY OF WETTING RAINS. THEREFORE...ANY LIGHTNING
   OVER VERY DRY FUEL BEDS WILL POSE AN IGNITION HAZARD.
