EVENT...DEVELOPING HEAVY RAIN THREAT
.
SATELLITE ANALYSIS AND TRENDS...LATEST WATER VAPOR IMAGERY CONTINUES TO
SHOW HIGHLY DIFFLUENT UPPER LEVEL PATTERN WITH TROF SHIFTING EAST AS UPPER
LOW BEGINS TO PUSH INTO SW KS. WATER VAPOR CHANNEL ALSO SHOWS A SUBTLE
SHORT WAVE MOVING UP THROUGH W IA THAT HAS ALSO HELPED INCREASE  LIFT.
MOISTURE ON THE BLENDED TPW PRODUCT SHOWS 2 CONNECTED PLUMES ONE ACROSS
CENTRAL TX NNE UP THE NORTHERN PLAINS AND A SECOND PLUME ORIGINATING
JUST OFF THE CAROLINA COAST. IN  FACT PWATS ARE RUNNING AROUND 1.7-1.9"
WHICH CORRESPONDS TO 145-175% OF NORMAL. THE BEGINNING SIGNAL FOR HEAVY
RAIN IS EVIDENT WITH IR SHOWING A GROWING CLUSTER OF ENHANCEMENT INVOF
PAGE COUNTY.  WITH SPC MESOANALYSIS PLACING BEST CAPES AS HIGH AS 4000
J/KG ACROSS SW IA COUPLED WITH HIGH RES MODELS INDICATING 25-30 KNOT
SOUTHERLY TO SW 85H FLOW WOULD ANTICIPATE CONVECTION TO EXPAND IN AREAL
COVERAGE. WOULD EXPECT POSSIBLE TRAINING CONVECTION ACROSS SW IA AND C
IA WITH RATES OF 1-2"/HR POSSIBLE. THE THREAT FOR SEVERAL INCHES OF RAIN
COULD PRESENT FF ISSUES ESPECIALLY AS POCKETS OF SW IA 3 HR FFG IS 1-1.5".
.
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  0115-0600...MEDIUM CONFIDENCE FACTOR
IN SHORT TERM OUTLOOK...WITH HIGH RES MODEL GUIDANCE INDICATING INCREASED
THREAT FOR HEAVY RAINS ACROSS SW IA, OTHER INDICATORS DISCUSSED ABOVE,
AND COORDINATION WITH METWATCH ANTICIPATE HEAVY RAIN THREAT TO INCREASE
NEXT FEW HOURS ACROSS SW AND CENTRAL IA.  RATES OF 1-2"/HR IS EXPECTED
IN BEST CONVECTION WITH POSSIBLE TRAINING LEADING TO FF ISSUES.
