SATELLITE ANALYSIS AND TRENDS...HI RES 1KM VIS IMAGERY SHOWS BNDRY
SITUATATED FROM ALONG THE WASHINGTON/FREDERICK COUNTY BORDER IN MD NEWD
THROUGH YORK/DAUPHIN/LEBANON COUNTIES WHERE STORMS CONTINUE TO TRAIN
INTO NE PA. SRN END OF THIS BNDRY IS SEEN ADVANCING TO THE NW AS SFC
WINDS ACROSS S CENTRAL PA/CENTRAL MD/NE VA ARE FROM THE SE. NRN END OF
THIS BNDRY HAS SHOWN LITTLE MOVEMENT HOWEVER AND AS A RESULT..TSTORMS
CONTINUE TO FORM TO THE S ALONG THIS BNDRY AND TRACK NEWD IN THE FLOW
FROM NRN YORK COUNTY/E CUMBERLAND INTO SRN/CENTRAL DAUPHIN AND LEBANON
COUNTIES. BOW ECHO WHICH HAS RAPIDLY FORMED AS IT MOVED OUT OF THE WV
PANHANDLE IS STRENGTHENING TO THE N AND S AND WILL BEGIN TO MERGE WITH
THE NWWD PUSHING BNDRY STARTING IN THE NEXT 20-40 MIN NEAR HGR. MERGERS
SHOULD CONTINUE NWD AS THE BNDRY AND THE TSTORMS TO THE WEST COLLIDE
PAINTING A BAND OF HEAVIER RAIN FROM WASHINGTON COUNTY MD LIKELY TO AT
LEAST JUNIATA/PERRY COUNTIES IN CENTRAL PA. MERGERS COULD CONTINUE FARTHER
TO THE N AS OBJECTIVE ANALYSIS DOES SHOW MAX MOISTURE CNVG OVER N CENTRAL
PA BUT WITH NRN END OF BNDRY STILL STUCK OVER NERN PA..UNCERTAINTY ABOUT
THIS IS GREATER. ESTIMATE THAT RAINFALL AMOUNTS OF 1-2" IN A 30 MIN TIME
PERIOD ARE CERTAINLY POSSIBLE DUE TO STRONG FORCING FROM THE COLLISION
OF THESE TWO BNDRYS. SEE WEB ADDRESS FOR GRAPHIC IN ABOUT 10 MIN.
