DAY 2 FIRE WEATHER OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0316 AM CDT SUN SEP 25 2016

VALID 261200Z - 271200Z

...CRITICAL FIRE WEATHER AREA FOR PORTIONS OF SOUTHERN CALIFORNIA...

...SYNOPSIS...
A MID-LEVEL REX PATTERN WILL EXIST ACROSS THE WEST THROUGH MUCH OF
THE PERIOD...AS A LOW DRIFTS NORTH NEAR THE GULF OF CALIFORNIA...AND
RIDGING REMAINS CENTERED OVER THE NORTHERN GREAT BASIN. THIS PATTERN
SHOULD MAINTAIN EASTERLY/OFFSHORE FLOW ALOFT ACROSS SOUTHERN
CALIFORNIA. ELSEWHERE...A CORRIDOR OF STRONG CYCLONIC FLOW SHOULD
ESTABLISH FROM MINNESOTA TO THE OH VALLEY...WITH A LOW SITUATED NEAR
LAKE SUPERIOR.

...PORTIONS OF SOUTHERN CALIFORNIA...
ANOTHER DAY OF CRITICAL FIRE-WEATHER CONCERNS IS ANTICIPATED ON
MONDAY...WITH GUSTY WINDS AND LOW RH VALUES LIKELY ONGOING ACROSS
TERRAIN-FAVORED AREAS AT THE BEGINNING OF THE PERIOD. FOLLOWING
SUNRISE...RH VALUES SHOULD QUICKLY FALL INTO THE SINGLE DIGITS AND
TEENS. WHILE MID-LEVEL FLOW WILL BE SOMEWHAT WEAKER THAN THAT OF THE
PREVIOUS DAY...IT SHOULD STILL SUPPORT GUSTY OFFSHORE FLOW THROUGH
THE MORNING/EARLY AFTERNOON HOURS...ONCE AGAIN BRINGING CRITICAL
FIRE-WEATHER CONCERNS TO MUCH OF THE AREA. SUSTAINED WINDS AROUND
20-25 MPH /WITH HIGHER GUSTS/ WILL COMBINE WITH RH VALUES BELOW 15
PERCENT...ESPECIALLY IN TERRAIN-FAVORED LOCATIONS...TO ENHANCE
FIRE-WEATHER CONCERNS. WHILE EASTERLY WINDS MAY INCREASE SOME MONDAY
NIGHT...SLIGHTLY HIGHER RH VALUES WILL BEGIN TO TEMPER THE THREAT
SOME LATE IN THE PERIOD.
