SHORT TERM OUTLOOK VALID 0100-0400Z...MEDIUM TO HIGH CONFIDENCE FACTOR
IN SHORT TERM OUTLOOK...WITH EVENT UNDERWAY AND EARLIER GUIDANCE PROVIDED,
GOING RIGHT TO OUTLOOK. SATELLITE SIGNATURE CONTINUES TO EVOLVE AS OLD
UPSTREAM MCV MOVING INTO S IN HELPS TO IGNITE GREATER UPSCALE CONVECTIVE
GROWTH IN AREA FROM S IN TO E KY/S WV AIDED BY ITS LOCATION WITHIN UPPER
RIDGE AXIS PER WATER VAPOR ANIMATION. PROFILES FROM RAP SOUNDINGS AND
NOW 00Z ILN RAOB CONTINUE TO INDICATE NEARLY UNIDIRECTIONAL NW MEAN
FLOW THROUGH THE CLOUD BEARING LAYER WHICH HAS ALLOWED FOR SOME BACK
BUILDING AND TRAINING. AT THIS POINT, ENOUGH COLD POOL FORMATION HAS
PROMOTED ENOUGH OF A SOUTHWARD PROPAGATION COMPONENT TO OFFSET THE BACK
BUILDING/TRAINING OVER THE W PORTION OF THE CONVECTIVE AREA. HOWEVER,
UPSTREAM DEVELOPMENT AND SUBSEQUENT TRAINING ALONG WITH MERGING ACTIVITY
CONTINUES TO PLAGUE E KY AND EXTREME SW WV THOUGH VERY RECENT TRENDS
APPEAR TO HAVE SHIFTED THE FOCUS JUST BARELY OUT OF WV AND MORE INTO E
KY. MESOANALYSIS INCLUDING DATA FROM 00Z RAOBS CONTINUES TO SHOW THE
LIKELIHOOD FOR ADDITIONAL CONVECTIVE DEVELOPMENT OVER S OH AND NE KY
DURING AT LEAST THE NEXT COUPLE OF HOURS WHICH SHOULD RESULT IN FURTHER
HEAVY RAINFALL OVER E KY AGGRAVATING ANY EXISTING FLOODING AND EXPANDING
THE OVERALL THREAT AREA SLIGHTLY AS WELL BEFORE RESIDUAL CAPE IS FINALLY
EXHAUSTED. PROFILES ALONG WITH RECENT BLENDED TPW DATA ARE INDICATING
1.75" TO 2.0" PRECIPITABLE WATER VALUES AND CONTINUING HIGH FREEZING
LEVELS LEADING TO VERY EFFICIENT RAINFALL PRODUCTION CAPABLE OF 2"/HR
RATES WITH THE STRONGER EMBEDDED CELLS.
