VALID 311200Z - 061200Z

HIGH-AMPLITUDE...WRN-CONUS RIDGING WILL CONTINUE INTO LATE THIS WEEK
AND EARLY THIS WEEKEND BEFORE GRADUALLY BREAKING DOWN. THIS WILL
OCCUR AS LOW-AMPLITUDE...WEAK...AND PERHAPS CONVECTIVELY AIDED
SHORTWAVE IMPULSES ADVANCE THROUGH THE WRN AND NRN FRINGES OF THE
RIDGE...AND AS AN E-CONUS TROUGH DE-AMPLIFIES. WITH SUFFICIENT
SUBTROPICAL AND MONSOONAL MOISTURE COVERING PORTIONS OF THE WRN
STATES...THUNDERSTORM CHANCES REMAIN IN THE FORECAST THROUGH THE
PERIOD ACROSS PORTIONS OF THE WEST -- AIDED BY DIURNALLY ENHANCED
OROGRAPHIC CIRCULATIONS. A FEW OF THESE STORMS MAY BE DRY...WITH
LIGHTNING-INDUCED IGNITIONS POSSIBLE ESPECIALLY ACROSS THE NWRN
CONUS AND ON THE EDGES OF RAIN CORES. HOWEVER...MEDIUM-RANGE MODEL
GUIDANCE OFFERS LOW CONFIDENCE THAT ANY SUBSTANTIAL PERTURBATIONS
ALOFT WILL STRONGLY 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.
