Tuesday Storm Timeline: Rain/Snow Line, Heavy Wet Snow Inland, Coastal Burst of Wind
A strengthening coastal storm arrives Tuesday with a sharp rain/snow line and a brief burst of wind at the coast. Here’s the breakdown:
Setup
• Cold high builds in today → locks in sub-freezing air for many tonight.
• Two waves (Gulf + Southern Plains) phase, tap Gulf/Atlantic, track near Nantucket Tue eve (fast mover).
Timing — TUESDAY
• 7–9 AM (W→E): Light precip arrives. SE New England already above 32°F → rain there.
• Mid-morning → midday: Rain/snow line (R/S) near I-128, creeping to I-495 and near the Mass Pike by early aftn.
• Midday → 8–9 PM (peak): Heavier bands. Interior = heavy, wet, pasty snow; SE New England = downpours. R/S collapses back toward the coast late evening as the column cools → flakes may reach into Boston late.
• Overnight Tue night: everything comes to an end, slippery untreated spots into Wed AM.
