..SYNOPSIS
UPPER-LEVEL TROUGHING WILL PERSIST ACROSS THE NORTHERN GREAT PLAINS
AND MIDWEST TODAY, WITH RIDGING IN PLACE ACROSS MUCH OF THE
SOUTHEAST/EAST COAST. UPPER-LEVEL RIDGING WILL ALSO GRADUALLY BUILD
ACROSS MUCH OF THE WESTERN CONUS THROUGH THE PERIOD. AT THE SURFACE,
A SERIES OF FRONTAL SYSTEMS WILL PROGRESS ACROSS THE GREAT PLAINS
AND EASTERN CONUS, WITH SEVERAL MID-LEVEL PERTURBATIONS PROMOTING
THE POTENTIAL FOR WETTING RAINFALL ACROSS MUCH OF THE SOUTHERN
PLAINS AND EASTERN US.
WARMING TEMPERATURES UNDER THE GRADUALLY BUILDING RIDGE WILL SUPPORT
RH REDUCTIONS TO 10-20% ACROSS MUCH OF THE SOUTHWEST AND PORTIONS OF
THE GREAT BASIN THIS AFTERNOON. WEAK SURFACE PRESSURE GRADIENT
MAGNITUDES AND, SUBSEQUENTLY, GENERALLY LIGHT SURFACE WINDS WILL
LARGELY TEMPER BROAD FIRE WEATHER CONCERNS ACROSS THE REGION.
SUSTAINED WESTERLY/SOUTHWESTERLY WINDS OF 10-15 MPH MAY PROMOTE
LOCALLY ELEVATED FIRE WEATHER CONCERNS IN FAVORED GAP/TERRAIN AREAS,
HOWEVER.
MID-LEVEL MOISTURE ATOP DEEP, WELL-MIXED BOUNDARY LAYER PROFILES MAY
SUPPORT WEAK BUOYANCY AND ISOLATED HIGH-BASED CONVECTION OVER HIGHER
TERRAIN ACROSS PORTIONS OF THE WESTERN GREAT BASIN INTO FAR
NORTHEASTERN CALIFORNIA AND SOUTHERN OREGON THIS AFTERNOON.
GENERALLY LIMITED LIGHTNING POTENTIAL AND SUB-CRITICAL FUELS SHOULD
TEMPER THE OVERALL LIGHTNING IGNITION THREAT, HOWEVER.
