DAY 1 FIRE WEATHER OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
1143 AM CDT FRI AUG 22 2014

VALID 221700Z - 231200Z

THE ONGOING FORECAST FOR ELEVATED FIRE WEATHER CONDITIONS REMAINS ON
TRACK.  THE DOWNSLOPE-INDUCED WARMING/DRYING EFFECTS AT THE SURFACE
WILL PLAY AN IMPORTANT ROLE IN ELEVATING FIRE WEATHER CONDITIONS
LATE THIS AFTERNOON OVER PORTIONS OF WCNTRL NV. THE ONLY CHANGE TO
THE OUTLOOK WAS TO TRIM THE NORTHERN PORTION OF THE ELEVATED AREA TO
FOCUS ON LOCATIONS IN THE LEE OF THE NRN SIERRAS.

.PREV DISCUSSION... /ISSUED 0317 AM CDT FRI AUG 22 2014/

...SYNOPSIS...
A CYCLONE AND SURROUNDING UPPER TROUGH POSITIONED OVER THE PAC NW
WILL DIG SLIGHTLY SWD...BEFORE ASSUMING A MORE ELY MOTION LATER
TODAY ACROSS THE INTER-MOUNTAIN WEST. AN ACCOMPANYING BELT OF
ENHANCED WLY FLOW WILL OVERSPREAD THE GREAT BASIN...AND SUPPORT AN
INCREASE IN SFC WIND SPEEDS THIS AFTERNOON OVER NV. FARTHER E...A
PROMINENT MIDLEVEL RIDGE WILL REMAIN CENTERED NEAR THE MS
VALLEY...SUPPORTING HOT/HUMID CONDITIONS ACROSS THE ERN TWO-THIRDS
OF THE CONUS.

...WRN NV...
AMIDST STRENGTHENING WLY LOW-MIDLEVEL FLOW ACCOMPANYING THE
AFOREMENTIONED LARGE-SCALE UPPER TROUGH...SUSTAINED WIND SPEEDS ARE
EXPECTED TO INCREASE TO 15 TO LOCALLY 20 MPH /STRONGER GUSTS/ BY
AFTERNOON IN THE LEE OF THE SIERRA ACROSS WRN NV. DOWNSLOPE-ENHANCED
WARMING/DRYING WILL AID IN RH VALUES FALLING TO 15-20
PERCENT...WHICH WILL COMBINE WITH THE ENHANCED WIND SPEEDS TO
PRODUCE AN ELEVATED FIRE WEATHER THREAT. HOWEVER...CONFIDENCE IN
WIDESPREAD CRITICALLY STRONG WIND SPEEDS IS QUITE LOW.
