VALID 201200Z - 211200Z
...CRITICAL FIRE WEATHER AREA FOR PORTIONS OF CENTRAL AND EASTERN
WYOMING...
..SYNOPSIS
A PERSISTENT UPPER-LEVEL RIDGE WILL REMAIN CENTERED OVER THE
SOUTHWEST ON D2/FRIDAY, WITH MODEST NORTHWEST FLOW ALOFT PERSISTING
ACROSS THE CENTRAL/NORTHERN HIGH PLAINS. SURFACE HIGH PRESSURE OVER
THE INTERMOUNTAIN WEST COUPLED WITH LEE TROUGHING ACROSS THE
NORTHERN PLAINS WILL SUPPORT A CONTINUED DOWNSLOPE WIND REGIME, WITH
DRY/WINDY CONDITIONS FORECAST TO YIELD ELEVATED TO CRITICAL FIRE
WEATHER CONCERNS ACROSS PORTIONS OF THE CENTRAL AND NORTHERN HIGH
PLAINS.
..CENTRAL/NORTHERN HIGH PLAINS
ANOMALOUSLY STRONG UPPER-LEVEL RIDGING ACROSS THE SOUTHWEST WILL
CONTINUE TO SUPPORT THE POTENTIAL FOR RECORD WARM TEMPERATURES
ACROSS MUCH OF THE WEST. WITH HIGH PRESSURE REMAINING POSITIONED
ACROSS THE INTERMOUNTAIN WEST AND LEE TROUGHING IN PLACE ACROSS THE
NORTHERN GREAT PLAINS, A PERSISTENT DOWNSLOPE WIND REGIME IS
FORECAST TO YIELD SUSTAINED WEST-NORTHWESTERLY SURFACE WINDS OF
15-25 MPH ACROSS MUCH OF THE CENTRAL/NORTHERN HIGH PLAINS. COUPLED
WITH REDUCED RH VALUES OF 10-15% AND RECEPTIVE FUELS, THIS WILL
SUPPORT CRITICAL FIRE WEATHER CONDITIONS ACROSS PORTIONS OF
CENTRAL/EASTERN WYOMING. ELEVATED FIRE WEATHER CONCERNS ARE FORECAST
ACROSS ADJACENT AREAS OF THE WESTERN WYOMING BASIN AND PORTIONS OF
SOUTHWESTERN SOUTH DAKOTA AND WESTERN NEBRASKA WHERE LIGHTER SURFACE
WINDS OF 15-20 MPH ARE FORECAST TO OVERLAP REDUCED MINIMUM RH VALUES
OF 10-15%. FARTHER NORTH ACROSS MUCH OF SOUTHERN MONTANA, RH VALUES
ARE EXPECTED TO REMAIN MORE MARGINAL (15-25%); HOWEVER, ONGOING FIRE
ACTIVITY AND SUSTAINED WESTERLY SURFACE WINDS OF 15-25 MPH WARRANT
THE ADDITION OF ELEVATED FIRE WEATHER HIGHLIGHTS.
..OREGON
SOME GUIDANCE INDICATES WESTERLY SURFACE WINDS WILL STRENGTHEN AMID
A TIGHTENING SURFACE PRESSURE GRADIENT AHEAD OF AN APPROACHING COLD
FRONT THROUGH D2/FRIDAY. CONTINUED DRY/WINDY CONDITIONS MAY SUPPORT
LOCALIZED ELEVATED FIRE WEATHER CONCERNS, BUT REMAINING UNCERTAINTY
REGARDING THE STRENGTH AND DURATION OF STRONGER WINDS AS WELL AS HOW
LOW RH WILL FALL IN THE AFTERNOON PRECLUDES THE INCLUSION OF
ELEVATED FIRE WEATHER HIGHLIGHTS AT THIS TIME. CONDITIONS WILL
CONTINUE TO BE MONITORED FOR FUTURE UPDATES.
