DAY 1 FIRE WEATHER OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
1128 AM CDT FRI SEP 19 2014

VALID 191700Z - 201200Z

...NO CRITICAL AREAS...

...ALONG AND NEAR THE ORE/WA BORDER...
SURFACE PRESSURE GRADIENT IS EXPECTED TO INCREASE THROUGHOUT THE
NIGHT AS HIGH PRESSURE BUILDS INTO THE NRN ROCKIES AND AN INVERTED
TROUGH REMAINS JUST OFF THE ORE COAST. THIS WILL LIKELY LEAD TO
MODERATE TO POOR OVERNIGHT RECOVERY AND SOME ENHANCED OFFSHORE WINDS
THROUGHOUT THE HIGHER ELEVATIONS. ANY ELEVATED CONDITIONS WILL
LIKELY REMAIN ISOLATED AND AN ELEVATED DELINEATION SEEMS
UNNECESSARY.

OVERALL...NO CHANGES WERE NEEDED. SEE PREVIOUS FORECAST DISCUSSION
BELOW.

..MOSIER.. 09/19/2014

.PREV DISCUSSION... /ISSUED 0355 AM CDT FRI SEP 19 2014/

...SYNOPSIS...
THE UPPER-AIR PATTERN WILL BEGIN TO TRANSITION FROM ZONAL /WITH THE
STRONGEST FLOW REMAINING ALONG AND NORTH OF THE UNITED STATES-CANADA
BORDER/ TO AMPLIFIED /WITH A RIDGE BUILDING ACROSS WESTERN CANADA
AND TROUGH DIGGING INTO THE CENTRAL UNITED STATES/. COINCIDENT WITH
THIS TRANSITION...A WEAK TROUGH OFF THE COAST OF CALIFORNIA WILL
BEGIN TO MOVE ASHORE.

ACROSS PORTIONS OF SOUTHERN IDAHO AND SOUTHERN WYOMING...BREEZY
SURFACE WINDS WILL COEXIST WITH RELATIVE-HUMIDITY VALUES BETWEEN 20
AND 35 PERCENT FOR A COUPLE HOURS DURING THE AFTERNOON.
HOWEVER...FUELS LOOK TO REMAIN TOO MOIST TO SUPPORT LARGE-SCALE
FIRE-WEATHER CONCERNS. ELSEWHERE...GIVEN THE LACK OF STRONG
LOW-LEVEL WINDS COUPLED WITH LOW RELATIVE-HUMIDITY
VALUES...LARGE-SCALE FIRE-WEATHER CONCERNS ARE NOT EXPECTED.
