This needs work, but I gave it a half-hearted try:
Simulated Radar Loop: March 11–14, 1888
March 11 (Evening): A low-pressure system moves up the Atlantic coast, initially appearing as a broad area of light-to-moderate rain across the Mid-Atlantic.
March 12 (Midnight): As the storm reaches the New Jersey coast, it undergoes explosive cyclogenesis. On radar, you would see a sharp "rain-to-snow" line as cold Canadian air rushes in, turning precipitation into heavy, blinding snow over NYC.
March 12 (Midday): The storm's "eye" or center (reaching a peak intensity of 978 hPa) sits just offshore. A massive, stationary band of intense snowfall (reflectivity values of 40+ dBZ) stalls over New York and western New England.
March 13: Instead of moving out to sea, the cyclone loops counterclockwise near the southern New England coast. On a loop, the heavy snow bands would appear to rotate and pinwheel over the same regions for over 24 hours, dumping up to 22 inches in NYC and nearly 60 inches in parts of New Jersey and upstate New York.
March 14: The system finally weakens and drifts east into the Atlantic, with the simulated radar showing the heavy bands breaking into scattered snow showers.
