DAY 3-8 FIRE WEATHER OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0327 PM CDT SUN JUL 27 2014
VALID 291200Z - 041200Z
SWLY FLOW ALOFT ON THE WRN PERIPHERY OF A HIGH-AMPLITUDE WRN-CONUS
RIDGE WILL MAINTAIN ENHANCED MID-LEVEL MOISTURE ACROSS PARTS OF THE
NWRN CONUS. THIS IS WHERE OROGRAPHIC CIRCULATIONS AND GENERALLY
MINOR DISTURBANCES EMBEDDED WITHIN THE FLOW WILL SUPPORT OCCASIONAL
THUNDERSTORMS THROUGH THE PERIOD. A FEW OF THESE STORMS MAY BE
DRY...WITH LIGHTNING-INDUCED IGNITIONS POSSIBLE. HOWEVER...
MEDIUM-RANGE MODEL GUIDANCE SOLUTIONS OFFER LITTLE CONFIDENCE THAT
SUBSTANTIAL PERTURBATIONS ALOFT WILL ENHANCE THUNDERSTORM COVERAGE
IN AREAS WHERE THERMODYNAMIC PROFILES WOULD SUPPORT A
DRY-THUNDERSTORM MODE. ADDITIONALLY...RELATIVELY LIMITED STORM
MOTIONS AND PW VALUES OVER 0.75 INCH COULD SUPPORT STORMS WITH
WETTING RAINS IN MANY AREAS. AS SUCH...PROBABILISTIC DELINEATIONS
HAVE NOT BEEN INCLUDED AT THIS TIME FOR DRY THUNDERSTORMS.
OTHERWISE...CRITICAL FIRE WEATHER CONDITIONS OWING TO THE OVERLAP OF
LOW RH AND STRONG WINDS ARE NOT EXPECTED.
