EVENT...COOLING CLOUD TOPS NOW BRINGING HEAVIER RAINS TO PARTS OF KY/OH/WV
.
SATELLITE ANALYSIS AND TRENDS...WV IMAGERY SHOWS BAROCLINIC LEAF PATTERN
MOVING ACROSS THE OH VLY AT THIS TIME WITH ABOVE AVG MOISTURE IN PLACE
ALONG AND PUSHING N OF THE FRONTAL BNDRY. CLOUD TOP TEMPS HAVE BEEN
COOLING OVER SRN OH INTO WRN PA WITH TEMPS NOW REACHING -55C. THOUGH
WARMER..CLOUD TOPS HAVE ALSO BEEN EXPANDING TO THE SW IN WRN KY..ANOTHER
STLT SIGNATURE OF INCREASING PRECIP RATES OVER THE REGION. AXIS OF BEST
THETA-E NOSES INTO E KY/SW WV ADVECTING WARM AIR NEWD JUST AHEAD OF THE
HEAVIEST PRECIP. CLOUD TOPS HAVE COOLED RECENTLY JUST W OF THE NOSE OF THE
THETA-E AXIS IN RESPONSE TO THIS INSTABILITY. STLT WINDS SHOW RIGHT ENT
REGION OF JET STREAK JUST TO THE N OF NE KY/S OH WHICH IS AIDING IN UVM
OVER THE AREA..ALONG WITH THE MOD TO STRG LOW LVL MOISTURE CNVG ALONG THE
FRNT AND ORAGRAPHIC LIFT AS CELLS ARE PUSHED INTO THE HIGHER TERRAIN OF
E OH/W PA. ALREADY PER RECENT SFC OBS HAVE SEEN SOME .25" AMOUNTS IN 1 HR
AND SHOULD SEE SOME INCREASE IN RATES ACROSS NRN KY INTO SRN OH OVER NEXT
1-2 HRS. ESTIMATE THAT MAX RAINFALL RATES OF .4-.6"/PER HR ARE POSSIBLE
OVER THE ABOVE MENTIONED AREAS. STORMS WILL BE TRACKING OVER ROUGHLY
THE SAME AREA FOR THE NEXT SEVERAL HRS WITH BIGGEST THREAT FOR FLOODING
ACROSS N KY/S OH/NW WV AND INTO EXTREME SW PA AS FFG IS RELATIVELY LOW
ACROSS SOME OF THESE PARTS. AS THE MOISTURE PUSHES INTO SWRN/W CENTRAL
PA AND EVEN THE CENTRAL PARTS OF OH..SFC TEMPS DROP BELOW FREEZING AND
THUS FREEZING RAIN WILL BE OF MOST CONCERN FOR THE EARLY MORNING HRS.
