SYNOPSIS...ALF..AT 04Z TROF DIGGING SWD WITH EMBD S/WV CROSSING
UT/AZ BORDER. FLOW IS W ACRS FCST AREA WITH WIND MAX FROM W TO E
ACRS SRN PTNS. AT 22Z...TROF WILL DIG FURTHER WWD WITH AXIS EXTDG
FROM NERN MT TO WRN NV. WND WILL GRADUALLY BEGIN TO TURN TO N
ACRS NRN AREAS WITH THE JET STRENGTHENING ACRS NRN AZ INTO NRN NM
AND SRN CO. FLOW WILL BE W TO SW IN NRN PTNS.
SFC..STNR FNT EXTDG FROM ERN ID/WRN MT S INTO NRN UT INTO W CNTRL
CO AND THEN ALONG CONT DVD THRU NM. LOW PRES IN S CNTRL ID AS
WELL AS ERN CO. HIGH PRES IN CNTRL UT. BY 22Z...STNR FNT WILL BE
ACRS WRN ID INTO NRN UT AND ERN CO DOWN THRU WRN NM. THE TAIL END
OF A CLD FNT WILL MOVE INTO THE WY/CO BORDER AREA. HIGH PRES BLDG
INTO NERN PTNS OF FCST AREA WITH LOW PRES ELSW.
