Here ya go- I am lazy tonight so here is what AI says(not perfect, but captures the general idea), and you and I both know this is 'typical' of la Nina winter storms in our region:
A Northward-Displaced Jet Stream
During a La Niña winter, the Pacific jet stream shifts much farther north across North America. [1, 2]
The Missing Southern Track: Unlike El Niño, which features a strong, moisture-rich southern jet stream tracking across the Gulf of Mexico and directly up the East Coast, La Niña suppresses this southern branch. [1, 2, 3]
The Continental Route: Instead, storms primarily track across the northern tier of the United States or the Ohio Valley. These are often fast-moving continental systems (like Alberta Clippers) that lack deep subtropical moisture while traveling over land. [1, 2]
2. Offshore Cyclogenesis (Later Development)
Because these northern storms travel over dry land, they remain relatively weak and disorganized while passing over inland regions of the Mid-Atlantic. [1]
The Gulf Stream Spark: It is only when the system’s energy finally moves offshore and encounters the stark temperature contrast of the warm Atlantic waters (the Gulf Stream) that it finds the thermal energy and moisture required to rapidly intensify.
This delayed strengthening means the low-pressure system matures "later" in its lifecycle, positioning its center well off the coast rather than inland.
3. The "Inland Dry vs. Coastal Wet" Divide
The offshore positioning of the storm center directly dictates who receives precipitation: [1]
Inland Regions Starve for Moisture: Because the storm intensifies far out at sea, its main moisture field is pulled eastward into the Atlantic. Behind the storm, a brisk northwest flow pulls cold, dry continental air down from Canada, suppressing precipitation and keeping inland regions under dry spells.
Coastal Areas Get Clipped: Even though the center of the Nor'easter or coastal storm is far offshore, these systems are massive. The western edge of the rotating storm shield—along with strong onshore winds—can still wrap around and clip the immediate coastline and the I-95 corridor
