VALID 181200Z - 191200Z
..NO CRITICAL AREAS
..AFTERNOON UPDATE
PREDOMINATELY WET THUNDERSTORMS ASSOCIATED WITH THE REMNANTS OF TS
MARIO ARE EXPECTED OVER MUCH OF CENTRAL AND SOUTHERN CA D2/THURSDAY.
MORE ISOLATED STORMS MAY DEVELOP ACROSS PARTS OF NORTHERN CA AND
SOUTHERN OR INTO EARLY D3/FRIDAY. HOWEVER, WEAK CAPE AND RAPIDLY
INCREASING HUMIDITY SUGGEST ANY RISK FOR LIGHTNING IGNITIONS WILL BE
SHORT-LIVED AND LOCALIZED. THEREAFTER, HIGHER CHANCES OF WETTING
RAINFALL ARE EXPECTED TO CONTINUE TO TEMPER FUELS. OTHERWISE, NO
CHANGES WERE MADE, OVERALL FIRE-WEATHER CONCERNS ARE LOW.

..SYNOPSIS
A MID-LEVEL TROUGH WILL SLOWLY PROGRESS EASTWARD ACROSS THE PLAINS
INTO THE UPPER MISSISSIPPI VALLEY WHILE ANOTHER DIFFUSE UPPER TROUGH
LINGERS ALONG THE WEST COAST, AND UPPER RIDGING PERSISTS OVER THE
OHIO VALLEY TOMORROW (THURSDAY). ANOTHER DAY OF QUIESCENT FIRE
WEATHER CONDITIONS IS IN STORE FOR MUCH OF THE U.S. WEST OF THE
ROCKIES. HOWEVER, A DRY LOW-LEVEL AIRMASS WILL CONTINUE TO
OVERSPREAD THE OHIO VALLEY, WHERE FUELS CONTINUE TO DRY AND
APPRECIABLE RAINFALL REMAINS ABSENT. AS ON DAY 1, THE SURFACE WIND
FIELD WILL BE TOO WEAK TO SUPPORT RAPID WILDFIRE-SPREAD POTENTIAL.
HOWEVER, THE AFOREMENTIONED DRY AIRMASS OVER DRY FUELS SUGGESTS THAT
LOCALIZED FIRE WEATHER CONDITIONS MAY BE A CONCERN WITH THE MOST
VULNERABLE FUEL BEDS.
