...SYNOPSIS...
A MID/UPPER-LEVEL LOW ACROSS THE OH VALLEY WILL SLOWLY FILL

WILL DE-AMPLIFY THROUGH THE PERIOD...AS A FAIRLY LARGE TROUGH PUSHES
ONSHORE THE WEST COAST.

SIMILAR TO THE PREVIOUS DAY...THE REGION WILL BE UNDER THE INFLUENCE
OF ENHANCED SOUTHWESTERLY FLOW ALOFT...WITH EVEN STRONGER FLOW
EXPECTED ON FRIDAY AS AN EMBEDDED IMPULSE MOVES ASHORE THE NORTHERN
CA/SOUTHERN ORE COAST. AS A RESULT...SUSTAINED SOUTHWEST WINDS
AROUND 15-25 MPH ARE EXPECTED ACROSS NORTHWEST NV AND VICINITY ON
FRIDAY. WHILE MID/UPPER-LEVEL MOISTURE WILL INCREASE WITH THE
APPROACH OF THE TROUGH...DIURNAL MIXING AND DOWNSLOPE FLOW SHOULD
STILL ENCOURAGE RH VALUES AROUND 15-20 PERCENT. AS
SUCH...ELEVATED/LOCALLY CRITICAL FIRE-WEATHER CONCERNS SHOULD
