VALID 031200Z - 041200Z

...CRITICAL FIRE WEATHER AREA FOR CNTRL WYOMING...

HAVE ADDED AN ELEVATED AREA FOR PORTIONS OF SWRN OREGON AND A SMALL
PORTION OF NWRN CA FOR NELY/OFFSHORE WINDS/DRY FUELS AND VERY DRY
CONDITIONS.

...CNTRL/SRN WY...
PREVIOUS FORECAST FOR THIS CRITICAL FIRE WEATHER AREA AND
SURROUNDING ELEVATED FIRE WEATHER AREA REMAINS ON TRACK AS MODELS
CONTINUE TO FORECAST WARMER AND SLIGHTLY DRIER FOR WEDNESDAY
COMPARED TO TODAY.  MOST HIGHS AT LOWER ELEVATIONS WILL MAKE IT INTO
THE LOW 80S WITH HUMIDITY IN THE TEENS AND W/SWLY WINDS AT 25 TO 30
MPH AND GUSTS OVER 35 MPH IN THE CRITICAL AREA WITH 15 TO 25 MPH AND
A FEW HIGHER GUSTS IN THE SURROUNDING ELEVATED AREA.

...A SMALL PORTION OF SWRN OREGON AND NWRN CA...
WITH AN INVERTED SURFACE TROUGH ALONG THE NW CA COAST...MID AND HIGH
ELEVATIONS SHOULD SEE NELY/OFFSHORE WINDS OF 15 TO 20 MPH AND
HUMIDITY FROM 10 TO 15 PERCENT.  IT WILL ALSO CONTINUE WARM TO HOT
AT LOWER ELEVATIONS.  THE AIR MASS IS EXTREMELY DRY WITH LOWEST
PRECIPITABLE WATER AT OR BELOW 0.25 INCH AND FUELS REMAIN VERY DRY
ACROSS THE AREA...DUE TO THE ONGOING DROUGHT AND POOR OVERNIGHT
HUMIDITY RECOVERY.

...SYNOPSIS...
PROGRESSIVE SHORTWAVE TROUGH WILL MOVE ENEWD FROM THE PACIFIC NW
ACROSS THE NRN ROCKIES AND INTO SRN SASKATCHEWAN WHILE SUBTROPICAL
RIDGING PERSISTS ACROSS THE SOUTHEAST AND SRN PLAINS. AT THE
SURFACE...COLD FRONT ASSOCIATED WITH THE PACIFIC NW SHORTWAVE WILL
PUSH EWD/SEWD ACROSS THE NRN ROCKIES AND NRN GREAT BASIN. BY
00Z/THU...THIS COLD FRONT IS EXPECTED TO EXTEND FROM THE MT/ND
BORDER SWWD INTO CNTRL NV.

...CNTRL/SRN WY...
UPPER FLOW ACROSS THE REGION WILL BECOME MORE SWLY AND INCREASE
SLIGHTLY AS THE SHORTWAVE MOVES THROUGH MT. SURFACE PRESSURE
GRADIENT WILL ALSO INCREASE AHEAD OF THE COLD FRONT. THESE FACTORS
WILL HELP SUPPORT SUSTAINED WLY/SWLY SURFACE WINDS AROUND 25-30 MPH
WITH GUSTS OVER 35 MPH. TEMPERATURES WILL BE A FEW DEGREES WARMER
THAN TUESDAY WITH RESULTANT RH VALUES GENERALLY FROM 12 TO 17
PERCENT. THE LOWEST RH VALUES ARE EXPECTED ACROSS CNTRL WY WHERE
TEMPERATURES WILL REACH THE MID 80S. AS A RESULT...CRITICAL FIRE
WEATHER CONDITIONS ARE EXPECTED ACROSS CNTRL WY WITH ELEVATED TO
LOCALLY CRITICAL CONDITIONS ELSEWHERE ACROSS THE REGION.
