WEAK LEE TROUGH IS FORECAST TO BECOME POSITIONED OVER W TX/ERN NM.
EAST OF THIS TROUGH...SURFACE PRESSURE GRADIENT WILL
STRENGTHEN...FAVORING SUSTAINED WIND SPEEDS AT OR SLIGHTLY ABOVE 20
MPH FROM THE ERN TX PANHANDLE INTO WRN OK. MEANWHILE...TEMPERATURES
WILL WARM INTO THE UPR 60S AND 70S...WHILE DEWPOINTS REMAIN IN THE
TEENS AND 20S...RESULTING IN CRITICAL RH VALUES BETWEEN 10 TO 15
PERCENT. A REGION OF OVERLAP BETWEEN THE DRY AIRMASS AND STRONGER

NM...AND THE TX/OK PANHANDLE...
...SYNOPSIS...
A SHORTWAVE TROUGH ENTERING SRN CA ON D1 WILL BE KICKED EASTWARD
INTO THE CENTRAL PLAINS BY A STRONGER TROUGH DROPPING SOUTH ALONG
THE WEST COAST. AS THIS OCCURS...AN AREA OF SURFACE LOW PRESSURE IS
EXPECTED TO STRENGTHEN AND MOVE EAST INTO THE NRN PLAINS. A TROUGH
AXIS WILL EXTEND SOUTH FROM THE LOW INTO THE CENTRAL AND SOUTHERN
HIGH PLAINS...ACCOMPANIED BY WARM TEMPERATURES AND LOW HUMIDITY.
...CRITICAL FIRE WEATHER AREA - PORTIONS OF ERN CO...WRN KS...ERN
NM...AND THE TX/OK PANHANDLE...
PRIMARY CONDITIONS: LOW RH...WIND...ABNORMALLY DRY TO MODERATE
DROUGHT
AS A SHORTWAVE TROUGH MOVES EAST ACROSS THE CENTRAL HIGH
PLAINS...SURFACE WINDS ARE EXPECTED TO STRENGTHEN TO 20 MPH OR
GREATER /WITH GUSTS UP TO 30 MPH/ DURING THE AFTERNOON. THESE WINDS
WILL OCCUR WITHIN AN AXIS OF VERY WARM TEMPERATURES AND RH VALUES
BELOW 20 PERCENT...EXTENDING NORTH FROM THE TX PANHANDLE INTO ERN CO
AND WRN KS. THESE FACTORS COMBINED WITH ABNORMALLY DRY TO LOCALLY
MODERATE DROUGHT CONDITIONS WILL SUPPORT A CRITICAL FIRE WEATHER
AREA OVER PORTIONS OF THE CENTRAL AND SRN HIGH PLAINS.
...SE WY AND THE SRN NEB PANHANDLE...
SUSTAINED WINDS OF 20 TO 30 MPH...WITH GUSTS APPROACHING 40 MPH ARE
POSSIBLE AS A SHORTWAVE TROUGH MOVES EAST ACROSS SE WY AND THE SRN
NEB PANHANDLE. HOWEVER...DAYTIME HIGHS ARE CURRENTLY FORECAST TO
REMAIN AT OR BELOW 60 DEGREES...AND RH VALUES WILL GENERALLY BE IN
THE 20 TO 30 PERCENT RANGE. THUS...A CRITICAL AREA WILL NOT BE
