DAY 2 FIRE WEATHER OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0253 AM CDT FRI JUL 29 2016

VALID 301200Z - 311200Z

...CRITICAL FIRE WEATHER AREA FOR PORTIONS OF THE COLUMBIA BASIN...

...SYNOPSIS...
AN UPPER SHORTWAVE TROUGH WILL TRACK ACROSS THE PACIFIC NORTHWEST
AND NORTHERN ROCKIES ON SATURDAY. FALLING HEIGHTS AND INCREASED DEEP
LAYER WESTERLY FLOW ASSOCIATED WITH THE TROUGH WILL RESULT IN
INCREASING SURFACE WINDS AHEAD OF AN EASTWARD ADVANCING COLD FRONT.
WESTERLY SURFACE WINDS NEAR 20 MPH WITH SOME HIGHER GUSTS ARE
EXPECTED AS RH VALUES FALL TO AROUND 15-20 PERCENT. THESE WINDY/DRY
CONDITIONS IN COMBINATION WITH DRY FUELS WILL LEAD TO CRITICAL FIRE
WEATHER CONDITIONS. ELEVATED FIRE WEATHER CONDITIONS WILL EXTEND
FURTHER SOUTH THROUGH EASTERN OREGON INTO NORTHWEST NV AND FAR NE
CA. WIND SPEEDS WILL BE SOMEWHAT WEAKER HERE...BUT RH VALUES WILL BE
CRITICALLY LOW. ADDITIONALLY...ISOLATED DRY THUNDERSTORMS WILL BE
POSSIBLE FROM SOUTHEAST OREGON TO THROUGH THE SIERRA MOUNTAINS
EASTWARD ACROSS THE GREAT BASIN AND CENTRAL/NORTHERN ROCKIES.
