SATELLITE PRECIPITATION ESTIMATES..DATE/TIME 04/26/15 0004Z
SATELLITE ANALYSIS BRANCH/NESDIS---NPPU---TEL.301-683-1404
LATEST DATA USED: GOES-EAST:2345Z  JS

LOCATION...EXTREME SW VIRGINIA/N TENNESSEE/KENTUCKY...

ATTN WFOS...MRX...JKL...LMK...OHX...PAH...
ATTN RFCS...OHRFC...LMRFC...

EVENT...MARGINAL THREAT FOR LOCALIZED HEAVY RAINFALL FOR NEXT SEVERAL
HOURS FROM SW KY TO SE KY/FAR SW VA/N CENT TN.
.
SATELLITE ANALYSIS AND TRENDS...WITH EVENT INITIATED, EMPHASIS NOW ON
OUTLOOK. VERY WELL DEFINED W-E ORIENTED FRONTAL BOUNDARY ACROSS KY WILL
SERVE AS CONTINUED FOCUS FOR DEVELOPMENT FED BY 30-40KT SLOWLY VEERING
SW-WSW LLJ AND RELATIVELY NARROW AXIS OF MAX RELATIVE INSTABILITY PER
ANIMATION OF GOES SOUNDER LI/CAPE PRODUCT AND EXPERIMENTAL NEARCAST
VERTICAL THETA-E DIFFERENCING PRODUCT WHICH IS NOTED FROM SE MO TO SE
KY. RATHER LOW EL`S/WARMER CLOUD TOPS IN CONJUNCTION WITH WELL DEFINED
VORT CIRCULATION SEEN IN WATER VAPOR/GOES RGB AIR MASS PRODUCT OVER
IL SHOULD STILL ALLOW FOR SOME INTENSE RAINFALL RATES ON THE ORDER OF
1"-2"/HR AND ISOLATED BRIEFLY HIGHER THAN 2"/HR DESPITE ONLY MARGINAL
MOISTURE THROUGH THE COLUMN(1.0"-1.2" PW VALUES). MID LEVEL DRIER AIR AND
EMBEDDED MCV ALONG W KY PORTION OF THE LINE SHOULD RESULT IN ADDITIONAL
COLD POOL FORMATION AND CONTINUED PROPAGATION OF LINE TO THE E AND SE WITH
LOW PROBABILITY HEAVY RAIN THREAT DICTATED BY BRIEF INTENSE RAIN RATES AND
SOME SHORT TERM POTENTIAL FOR TRAINING GIVEN W-E ORIENTATION OF ACTIVITY
AND NEW CELL FORMATION STRETCHING ACROSS MUCH OF KY. HAVE SEEN SOME
MESONET REPORTS OF OVER 1" OVER W KY SO 1"-2" LOCALIZED AMOUNTS WITH ISOL
TOTALS OVER 2" ACROSS A PORTION OF THE AREA FROM SW KY TO E AND SE KY,
FAR SW VA, AND THE NORTHERN PORTION OF TN IS LIKELY WHICH WILL APPROACH
THE APPARENT FFG VALUES PARTICULARLY OVER THE E PORTION OF THE DISCUSSION
AREA (SEE APPENDED OUTLINED GRAPHIC ON INTERNET IN APPROX 10 MINUTES).
.
AN ANNOTATED SATELLITE GRAPHIC SHOWING THE HEAVY PRECIPITATION
THREAT AREA SHOULD BE AVAILABLE ON THE INTERNET ADDRESS LISTED
BELOW IN APPROXIMATELY 10 MINUTES.
