UNITED STATES — The weather setup shown in the latest analysis highlights a classic Miller-B coastal snowstorm pattern, a configuration that historically produces heavy snow along parts of the Mid-Atlantic and Northeast coastline, but only under very specific atmospheric conditions. According to the data shown, this type of pattern is uncommon, occurring once every 6–7 years on average, with extended clusters appearing roughly once every 30 years.
The maps and annotations clearly indicate a clipper system transferring energy to the coast, allowing a new low-pressure system to strengthen offshore — the defining feature of a Miller-B storm. When this happens, inland energy weakens while coastal development intensifies, focusing snowfall near the Atlantic shoreline rather than far inland.
How the Miller-B Setup Works in This Pattern
The data visualization shows a primary low pressure (L) weakening inland, while energy shifts eastward toward the Atlantic Ocean. This transfer allows a secondary coastal low to develop and track northward just offshore.
In this configuration:
- Cold air is already in place across the Northeast.
- Moisture is pulled northward from the Atlantic.
- The strongest lift occurs near the coast.
This combination is why New Jersey, Long Island (New York), eastern Massachusetts, and coastal Maine are highlighted as the most vulnerable areas for heavy snow, while regions farther inland may see less impact or mixed precipitation.
Heavy Snow Axis Focused Along the Coast
The curved white track shown in the image outlines the primary heavy snow corridor, running from:
- Southern New Jersey
- Through Long Island and coastal New York
- Into eastern Massachusetts
- And potentially coastal Maine
This is a textbook Miller-B signature, where snowfall intensity increases closer to the coastline instead of farther west. The red arrow in the graphic represents strong moisture transport, which is essential for turning this setup into a high-impact snow event…
