..SYNOPSIS
BETWEEN A LARGE-SCALE RIDGE CENTERED ON THE SOUTHWEST/NORTHERN
MEXICO AND A BROAD/SLOW-MOVING MIDLEVEL TROUGH CROSSING NORTHERN CA,
ENHANCED WEST-SOUTHWESTERLY MIDLEVEL FLOW WILL OVERSPREAD THE
SOUTHERN GREAT BASIN. DEEP BOUNDARY-LAYER MIXING INTO THIS ENHANCED
FLOW ALOFT WILL YIELD HOT, DRY, AND BREEZY CONDITIONS DURING THE
AFTERNOON. GIVEN RECEPTIVE FUELS, ELEVATED FIRE-WEATHER CONDITIONS
ARE EXPECTED ACROSS SOUTHERN NV INTO SOUTHERN UT.
FARTHER NORTH, COOL TEMPERATURES ALOFT/STEEP MIDLEVEL LAPSE RATES
ACCOMPANYING THE TROUGH WILL PROMOTE ANOTHER DAY OF ISOLATED TO
WIDELY SCATTERED HIGH-BASED THUNDERSTORMS ACROSS THE NORTHERN GREAT
BASIN/INTERMOUNTAIN WEST. INVERTED-V PROFILES AND 0.6-0.7 INCH PW
WILL FAVOR MOSTLY DRY THUNDERSTORMS, WITH A RISK OF
LIGHTNING-INDUCED IGNITIONS OVER RECEPTIVE FUELS.
