DAY 2 FIRE WEATHER OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0225 AM CST THU NOV 22 2007
VALID 231200Z - 241200Z
...CRITICAL FIRE WEATHER AREA FOR COASTAL AREAS OF SOUTHERN CA...
...SYNOPSIS...
PRIMARY FIRE WEATHER CONCERNS FOR FRIDAY INTO THE WEEKEND WILL BE
FOCUSED ON SOUTHERN CA. LARGE SCALE UPPER FLOW PATTERN WILL BEGIN TO
SPLIT ON FRIDAY...HIGHLIGHTED BY AN UPPER TROUGH CENTERED OVER THE
GREAT LAKES...AND A SECONDARY IMPULSE SLIDING SOUTHEASTWARD OVER THE
SOUTHWEST STATES. HIGH PRESSURE BUILDING ACROSS THE GREAT
BASIN/INTERMOUNTAIN WEST WILL CAUSE THE OFFSHORE GRADIENT TO
INCREASE ACROSS SOUTHERN CA...LEADING TO A HEIGHTENED FIRE DANGER.
OTHERWISE...THE INFLUENCE OF HIGH PRESSURE AND COOL/DRY CONDITIONS
WILL LARGELY DOMINATE EAST OF THE ROCKIES.
...CRITICAL FIRE WEATHER AREA - COASTAL AREAS OF SOUTHERN CA...
PRIMARY CONDITIONS: STRONG/GUSTY OFFSHORE WINDS AND LOW RH/EXTREME
DROUGHT
OFFSHORE GRADIENT IS FORECAST TO STRENGTHEN ON FRIDAY AS HIGH
PRESSURE BUILDS ACROSS THE GREAT BASIN...ALL WHILE DEEP LAYER
NORTHEASTERLY FLOW DEVELOPS IN THE WAKE OF THE SOUTHEAST-SHIFTING
UPPER TROUGH. THE FIRE DANGER WILL INCREASE ACROSS SOUTHERN CA
ACCORDINGLY AS WINDS STEADILY INCREASE AND OFFSHORE/DOWNSLOPE
TRAJECTORIES LEAD TO A DRYING AIRMASS THROUGH THE PERIOD. THE
CULMINATION OF THE MODERATE TO POTENTIALLY STRONG OFFSHORE EVENT IS
EXPECTED FRIDAY NIGHT INTO THE FIRST PART OF SATURDAY...WITH THE
POTENTIAL FOR 20-40 MPH SUSTAINED WINDS AND LOCALLY HIGHER GUSTS FOR
THE COASTAL RANGE AND ADJACENT COASTAL AREAS. GIVEN THE ORIENTATION
OF THE OFFSHORE GRADIENT...WIND GUST POTENTIAL AND RESULTANT
CRITICAL CONDITIONS APPEAR MOST LIKELY ACROSS VENTURA/LOS ANGELES
COUNTIES...AS WELL AS ADJACENT PORTIONS OF ORANGE/RIVERSIDE AND SAN
BERNARDINO COUNTIES.
