SHORTWAVE NORTH OF THE BORDER IS SHEARING OUT AND THE FEW REMAINING
STORMS ARE MOVING SOUTHWARD INTO NORTH DAKOTA.  ONLY MAJOR CHANGE TO
THE ZONES IS TO SEPARATE OUT THE ZONES ALONG THE BORDER FOR LOWER
TEMPS TONIGHT.  DEWPOINTS AROUND THE AREA ARE ABOUT 5 DEGREES LOWER
COMPARED TO AREAS JUST TO THE SOUTH OF THIS REGION. BEST
THUNDERSTORM POTENTIAL REMAINS SOUTH OF OUR CWA TONIGHT.  OUR
DEWPOINTS ARE IN THE 40S AND 50S...WITH 60S IN KBIL CWA AND OUR
EXTREME SOUTHEAST COUNTIES.  BEST DYNAMICS AND SHEAR ARE TO OUR
SOUTH AS WELL. WILL TAKE OUT POPS IN THE WINNETT/JORDAN ZONES AND
LOWER THEM IN THE SOUTHEAST ZONE.  INTERESTING STORM SYSTEM IN STORE FOR
SATURDAY NIGHT AS A SHORTWAVE OFF THE CALIFORNIA COAST INTENSIFIES
AS IT OVER THE ROCKIES. ALL THE MODELS GIVE SIGNIFICANT
PRECIPITATION...ALTHOUGH THE AVN IS SLOWER THAN THE ETA AND NGM.

EXTENDED...MODELS IN REASONABLE AGREEMENT SHIFTING W CONUS RIDGE
WEST THRU FCST PD AFTER BRIEF FLATTENING OF RIDGE EARLY IN EXTENDED
PD. AS RIDGE SHIFTS FURTHER WEST...NW FLOW WILL PREVAIL WITH
POTENTIAL FOR IMPULSES IN NW FLOW TRIGGERING SHOWERS. BETTER CHANCE
ANTICIPATED FOR NE ZONES MONDAY AND TUES...SOMEWHAT FOR NW-SE ZONES
MONDAY...SO WILL INCLUDE CHANCE OF SHOWERS. SW ZONES APPEAR LIKELY
TO REMAIN DRY THROUGHOUT FCST PD. TEMPS SOMEWHAT PROBLEMATIC...BUT
WILL KEEP NEAR NORMAL RANGE AND MRF MOS VALUES.     SECORA
