DAY 2 FIRE WEATHER OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
1227 PM CST FRI FEB 26 2021
VALID 271200Z - 281200Z
RECENT HIGH-RESOLUTION MODEL GUIDANCE INDICATES SEVERAL AREAS OF
10-15% RH VALUES DURING PEAK HEATING WITH WIND SPEEDS OF AROUND
15-25 MPH WEST OF A SURFACE TROUGH EXTENDING FROM FAR WESTERN
OKLAHOMA THROUGH WEST TEXAS. ERCS ARE RELATIVELY LOW, THOUGH
CONSECUTIVE AFTERNOONS OF FULL SUNSHINE AND VERY DRY AIR WILL LIKELY
CONTRIBUTE TO DRYING OF FINER FUELS. AN ELEVATED FIRE-WEATHER
DELINEATION HAS BEEN ADDED TO ADDRESS THIS SCENARIO.
SEE THE PREVIOUS DISCUSSION BELOW FOR MORE INFORMATION.

..SYNOPSIS
MID-LEVEL FLOW IS EXPECTED TO INCREASE ACROSS THE SOUTHERN HIGH
PLAINS ON SATURDAY WITH SURFACE LEE CYCLOGENESIS EXPECTED IN
SOUTHEAST COLORADO. DEEP MIXING, COMBINED WITH THE STRENGTHENING
SURFACE PRESSURE GRADIENT, IS EXPECTED TO BRING WINDS OF 10 TO 25
MPH AND RELATIVE HUMIDITY LESS THAN 15 PERCENT ACROSS MUCH OF THE
SOUTHERN HIGH PLAINS. FUELS IN THE REGION ARE NOT CRITICALLY DRY AT
THIS TIME, AND THEREFORE, NO FIRE WEATHER HAZARDS HAVE BEEN ADDED.
HOWEVER, FUEL CONDITIONS WILL NEED TO BE MONITORED CLOSELY, AND IF
SIGNIFICANT DRYING OCCURS BEFORE SATURDAY, AT LEAST AN ELEVATED
DELINEATION MAY BE NEEDED.
