MEAN LARGE-SCALE PATTERN WILL LIKELY FAVOR AN UPPER TROUGH OVER THE
WRN CONUS THROUGH THE WEEKEND. AN INITIAL ASSOCIATED IMPULSE IS
FORECAST TO MOVE SWD ACROSS THE PAC NW ON THU/D3...AND WILL PROBABLY
RESULT IN INCREASED TSTM POTENTIAL FOR ERN WA...BUT THE POTENTIAL
FOR DRY TSTMS WILL BE LIMITED BY WEAK DEEP-LAYER FLOW AND MARGINAL
BOUNDARY LAYER DRYNESS. AS THIS SYSTEM PROGRESSES EWD INTO THE
WEEKEND...A DRIER AIR MASS WILL OVERSPREAD MUCH OF THE WRN
CONUS...AND SHOULD LEAD TO A GENERAL REDUCTION IN TSTM COVERAGE. THE
POTENTIAL FOR STRONG WINDS WILL ALSO BE FAIRLY LOCALIZED...WITH LOW
PROBABILITY FOR WIDESPREAD STRONG WIND/LOW RH EVENTS THROUGH NEXT
WEEK. AN UPPER RIDGE MAY RE-DEVELOP EARLY NEXT WEEK...AND COULD
FOSTER A GRADUAL INCREASE IN MOISTURE NWD FROM THE SOUTHWESTERN
