DAY 3-8 FIRE WEATHER OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0324 PM CDT WED AUG 20 2014
VALID 221200Z - 281200Z
AT THE BEGINNING OF THE EXTENDED PERIOD ON FRIDAY /D3/...THE
UPPER-LEVEL PATTERN WILL BE CHARACTERIZED BY A TROUGH OVER THE WRN
CONUS AND A RIDGE OVER THE ERN CONUS. ON SATURDAY /D4/...THE WRN
CONUS TROUGH /AND ASSOCIATED THUNDERSTORM THREAT/ IS EXPECTED TO
SHIFT EWD ACROSS THE INTERMOUNTAIN WEST. THE MODELS/ENSEMBLES BEGIN
TO DIFFER IN THE EVOLUTION OF THE TROUGH AFTER SATURDAY /D4/ WITH AN
EVENTUAL EWD SHIFT BY EARLY NEXT WEEK AS AN UPPER-LEVEL RIDGE BUILDS
TOWARD THE WEST COAST. OVERALL...A DRIER AIRMASS IN THE WAKE OF THE
TROUGH WILL GENERALLY RESULT IN REDUCED THUNDERSTORM POTENTIAL FOR
MUCH OF THE WEST. IN ADDITION...THE PROBABILITY OF STRONG WINDS
/AOA 20 MPH/ IN CONCURRENCE WITH CRITICAL RH VALUES APPEARS
RELATIVELY LOW DURING THE EXTENDED PERIOD ACROSS THE
CONUS...SUGGESTING LIMITED POTENTIAL FOR CRITICAL FIRE WEATHER
