DAY 2 FIRE WEATHER OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0240 AM CDT SUN JUN 23 2013

VALID 241200Z - 251200Z

...CRITICAL FIRE WEATHER AREA FOR NRN/ERN AZ...NRN/WRN NM...SRN/WRN
CO...S-CNTRL WY...SRN/CNTRL UT...ERN NV...PARTS OF CNTRL HIGH
PLAINS...

...SYNOPSIS...
THE LARGE SCALE PATTERN FEATURING A MEAN UPPER TROUGH OVER THE W AND
A FLAT/EXPANSIVE UPPER RIDGE OVER THE ERN CONUS WILL PERSIST THIS
PERIOD...AS A GREAT BASIN SHORTWAVE TROUGH ACCELERATES NEWD TOWARDS
THE NRN HIGH PLAINS...AND SEASONABLY STRONG WLYS NOSE INTO NRN CA.
PERSISTENT MODERATE SWLY DEEP-LAYER FLOW ACROSS THE SOUTHWEST WILL
RESULT IN ANOTHER ROUND OF CRITICAL FIRE WEATHER CONDITIONS FROM
PARTS OF AZ/NM NWD INTO THE ERN GREAT BASIN AND CNTRL ROCKIES.
HOT/HUMID CONDITIONS WILL CONTINUE MAINLY FROM THE LOWER GREAT
PLAINS EWD.

...NRN/ERN AZ...NRN/WRN NM...SRN/WRN CO...S-CNTRL WY...SRN/CNTRL
UT...ERN NV...PARTS OF CNTRL HIGH PLAINS...
A SLIGHT INCREASE IN DEEP-LAYER FLOW COMPARED TO SUN/D1 IS FORECAST
TO OCCUR...AS A SHORTWAVE UPPER TROUGH OVER THE GREAT BASIN
PROGRESSES EWD...AND STRONGER WLY FLOW ALOFT OVERSPREADS NRN/CNTRL
CA AND THE WRN GREAT BASIN. AS A RESULT...A LARGE AREA OF CRITICAL
FIRE WEATHER CONDITIONS WILL LIKELY DEVELOP DURING THE LATE MORNING
AND AFTERNOON...AS PRESSURE FALLS OVER THE ERN GREAT BASIN/ROCKIES
ENHANCE THE SFC PRESSURE GRADIENT...AND DEEP DIURNAL BOUNDARY LAYER
MIXING OCCURS. FORECAST MODEL GUIDANCE INDICATES WIDESPREAD SWLY SFC
WINDS OF 20-25 MPH /WITH HIGHER GUSTS/ ACROSS MOST OF THE SOUTHWEST
AND PARTS OF THE INTER-MOUNTAIN WEST. SIMILAR TO SUN/D1...A CORRIDOR
OF ENHANCED SFC WINDS IS ALSO FORECAST TO DEVELOP FROM CNTRL NM NEWD
INTO THE CNTRL HIGH PLAINS AS A DRYLINE MIXES EWD INTO WRN KS. A
HOT/DRY AIR MASS WILL CONTINUE TO YIELD SINGLE DIGIT TO LOWER TEEN
RH VALUES...WHILE FUEL CONDITIONS REMAIN DRY TO VERY DRY OVER MUCH
OF THE CRITICAL RISK AREA.
