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.
