EXTREME SOUTHWEST CORNER OF THE FORECAST AREA FORECAST TO NUDGE
ITS WAY NORTHEAST INTO THE SOUTHWEST 1/2 OF THE AREA BY DAYS END
BEFORE SLOWLY MOVING BACK TO THE SOUTH TONIGHT...PRECIPITATION
CHANCES ARE TIED TO THIS AREA OF MOISTURE AND IS FAIRLY SIMILAR TO
PREVIOUS FORECAST. PRECIPITABLE WATER VALUES RISE TOWARD 1.50-1.75
INCHES ACROSS THE FAR SOUTHERN PARTS OF THE AREA WITH STORM
MOTIONS 10 MPH OR LESS. THIS WILL INCREASE THE THREAT FOR LOCALLY
HEAVY RAINFALL. HIGHS TODAY IN THE LOW TO MID 80S WITH 60 TO 65 TONIGHT.

OUR AREA TUESDAY NIGHT. PRECIPITABLE WATER VALUES OVER 1.50 INCHES
EXPAND IN COVERAGE AND COVER MUCH OF THE AREA THROUGH THE PERIOD.
MODELS ALSO AGREE ON INCREASING JET DYNAMICS WITH THE VORT MAX
WHICH WILL HELP PROMOTE PRECIPITATION POTENTIAL. WITH STORM
MOTIONS REMAINING UNDER 10 MPH LOCALLY HEAVY RAINFALL AND FLASH

BRINGS DRIER AIR INTO THE AREA FROM THE NORTH/NORTHEAST MUCH
SOONER THAN THE GFS/ECMWF. WITH THE CLOUDINESS AND PRECIPITATION

WILL BE MAINLY IN THE MORNING TO PERHAPS VERY EARLY AFTERNOON. MAY
SEE SOME LOCALLY HEAVY RAINFALL IN THE MORNING BEFORE MUCH DRIER

RATHER A FEW GENERAL THUNDERSTORMS ARE MORE LIKELY.  SOME WEAK
SURFACE BOUNDARIES WILL BE PRESENT ACROSS THE HIGH PLAINS REGION
