SATELLITE ANALYSIS AND TRENDS...WV IMAGERY SHOWS THAT SYNOPTIC PATTERN
FEATURED SLOWLY PROGRESSIVE UPPER LOW OVER THE FOUR CORNERS REGION
WHILE ADDITIONAL ENERGY WAS DROPPING THROUGH PORTIONS OF THE GREAT BASIN
TOWARDS SW UT/N AZ AIDING IN HOLD MID LEVEL TROF AXIS BACK.  DOWNSTREAM,
MID LEVEL PLUME OF MOISTURE FROM MARIE HAS BEEN ENTRAINED INTO SYSTEM ND
WAS LIFTING NE TOWARDS THE CNTRL PLAINS.  LEAD IMPULSE WAS BEGINNING TO
LIFT OUT OF THE FRONT RANGE OF CO AND HAVE NOTED INCREASING AREA OF LARGE
SCALE ASCENT OVER PORTIONS OF CNTRL NE.  AT THE SURFACE QUASI-STATIONARY
OUTFLOW ENFORCED EFFECTIVE FRONTAL BOUNDARY WAS ROUGHLY ORIENTED FROM
PORTIONS OF CNTRL MO EXTENDING WNW THROUGH N KS TO SW PORTIONS OF NE.
GOES SOUNDER INDICATES THAT ATMOSPHERE WAS BECOMING MODESTLY TO LOCALLY
VERY UNSTABLE ROUGHLY ALONG THE FRONTAL BOUNDARY WITH SOME BREAKS IN THE
CLOUD COVER OVER PORTIONS OF NE AIDING IN DESTABILIZATION OVER PORTIONS
OF W NE.
.
AN ANNOTATED SATELLITE GRAPHIC SHOWING THE HEAVY PRECIPITATION
THREAT AREA SHOULD BE AVAILABLE ON THE INTERNET ADDRESS LISTED
BELOW IN APPROXIMATELY 10-15 MINUTES.
.
SHORT TERM OUTLOOK VALID 2000-0200Z...MEDIUM CONFIDENCE FACTOR
IN SHORT TERM OUTLOOK...ON THE SHORT TERM WOULD EXPECT ISOLATED CONVECTION
TO CONTINUE TO DEVELOP SUCH AS WHAT APPEARS TO BE OCCURRING IN THE VIC
OF LBF.  WOULD EXPECT MORE CONTINUED DEVELOPMENT AND ORGANIZATION TOWARDS
THE 0Z TIME FRAME AS LOW LEVEL FLOW BEGINS TO BACK AND STRENGTHEN IN
RESPONSE TO LIFTING IMPULSE OUT OF THE CO FRONT RANGE.  FAVORED STORM
MOTIONS SHOULD BE TO THE NNE WITH ANY INITIAL SUPER CELLS NEAR BACKED
WINDS CLOSER TO FRONTAL BOUNDARY POTENTIALLY TO BE QUITE SLOW MOVING.
AS LLJ INTENSIFIES TOWARDS THE END OF THIS TIME PERIOD AND BEYOND WOULD
EXPECT CONVECTION TO ORGANIZE INTO ONE OR MULTIPLE ORGANIZED CONVECTIVE
COMPLEXES.  NEARLY UNIDIRECTIONAL WSW/SW FLOW IN CLOUD BEARING LAYER
WOULD TEND TO SUGGEST FAVORED FORWARD PROPAGATING COMPONENTS TO THE
ENE.  WITH THE AMOUNT OF ENERGY UPSTREAM THOUGH, LLJ SHOULD BE SLOW
TO VEER AND THIS WOULD IMPLY THE POTENTIAL FOR SOME QUASI-STATIONARY
COMPONENTS/REGENERATION ON SW PERIPHERY OF OUTFLOW BOUNDARIES.    BLENDED
PW ANALYSIS WAS INDICATING RATHER ANOMALOUS MOISTURE ALONG SYNOPTIC
BOUNDARY WITH PW VALUES NEAR 150% ABOVE CLIMATOLOGICAL NORMAL VALUES.
CURRENT THINKING WOULD TEND TO SUGGEST HEAVIEST RAINFALL AXIS SHOULD
EXTEND FROM PORTIONS SW IA/NW MO W THROUGH NE PORTIONS OF KS AND E AND
CNTRL NE.
