What happened

The episode as NWS BGM wrote it up.

A slow moving storm from the Ohio Valley brought 2 to 4 inches of rain on April 2nd and 3rd. Before this storm, the rivers had high flows due to a previous rainstorm March 28th and snowmelt. By the time the river fell below flood stage most of the snow had melted. The Delaware River at Montague, NJ (near Milford, PA) rose to its flood stage of 25 feet the early on the 3rd, crested at 31.69 feet at 3:00 PM on the 3rd, then fell back below flood stage the morning of the 4th. This was the third highest flood of record and the highest in almost 50 years. In Dingmans Ferry, the bridge across the Delaware River was closed. The river crest was 3 feet under the bridge. Many roads along the river were damaged.

FLOODING WITH MANY COUNTIES UNDER AS STATE OF EMERGENCY. HARDEST HIT
AREAS APPEAR TO BE FROM THE POCONOS INTO THE CATSKILLS. AREA OF
TSTMS ASSCD WITH S/WV TRACKING ACRS NE PA INTO CNTRL NY IS ONLY
ADDING TO THE CONSIDERABLE FLOODING WOES.

HYDRO CONCERNS OBVIOUSLY THE MAIN FOCUS THIS MRNG, BUT SOME WINTER
WX ALSO A CONCERN. CRNT RAIN/SNOW LINE RUNS APPROX ALONG THE 925 MB
-1C LINE AS SHOWN IN THE ETA12. MDLS SHOW SOME 850 MB COOLING ACRS

CHGOVER AT ELM ARND 14Z, ITH 21Z WITH SYR AND BGM NOT UNTIL AFTER
00Z. THESE TIME ARE DEBATABLE SO WONT GET REAL SPECIFIC IN THE

ALWAYS BUST POTNL WITH THESE CUTOFFS, BUT WE PLAN ON
MIXING/CHANGING OVER THE RAIN TO SNOW OVER THE CNTRL SRN TIER AND
BRADFORD COUNTY TDA WITH POTNL FOR AN INCH OR TWO OF ACCUM MAINLY
ACRS THE HIGHEST ELEVATIONS. WILL MENTION PSBL MIX INTO THE
SYR/BGM/AVP AREAS BY LATE TDA BUT NO ACCUMS. TNGT, XPCT ANY -SHRA
ACRS ERN ZONES TO FINALLY SWITCH OVER. WILL FCST ACCUMS BLO ADVISORY
CRITERIA FOR TNGT WITH 1-3 NRN FINGER LAKES INTO WRN MOHAWK VLY, AN

AREA TO BE IN THE FOCUS AREA OF BAROCLINIC ZONE UNDER UPR JET...THUS

PRETTY GOOD MODEL AND ENSEMBLE AGREEMENT...WILL CONTINUE WITH CHANCE
POPS AT THIS TIME RANGE.
