TIMELINE: What to expect from Wednesday's nor'easter

Less than a week after a coastal storm hammered the area with snow and strong winds, another storm is set to drop significant snow across most of the 69 News viewing area.

WFMZ meteorologists are tracking the storm as it develops. Here's a look at the timeline of the storm as it works its way through the area.

TUESDAY EVENING: Light mix of rain and snow develops from west to east. Some areas may see just light snow from the beginning.

TUESDAY NIGHT: Temperatures continue to drop and any rain transitions to all snow overnight. Snowfall will be light but accumulation is expected overnight, roads start to become slippery.

EARLY WEDNESDAY MORNING: Some snow accumulates by sunrise. Roads become slick as wind picks up and snow becomes heavier. Travel will be messy and difficult.

WEDNESDAY MORNING: The heaviest snow hits around late morning. Bands of very heavy snow are possible with snowfall rates of 1 to 2 inches per hour, most likely in parts of far eastern Pennsylvania and northern New Jersey. Any travel will be very difficult to impossible.

WEDNESDAY MID-DAY: Heavy, wet snow continues to fall during the day. Sustained winds blow up to 20 mph, with gusts up to 40 mph. Widespread six to 12 inches of snow expected.

WEDNESDAY AFTERNOON: Snow begins to taper sometime late Wednesday afternoon, from southwest to northeast. Brisk winds continue to blow.

WEDNESDAY EVENING: The storm should pull away by evening hours, but with the winds and several inches of snow roads will still be slick through the evening commute.

ACCUMULATION: Most of the 69 News viewing area is under a winter storm warning, meaning at least six inches of snow is expected from Tuesday night through Wednesday night. The Lehigh Valley, Poconos, northern New Jersey and southeastern Pennsylvania down to about Philadelphia are expected to get six to 12 inches of snow. Locally, some areas could see 12+ inches. A sharp cutoff to the steadiest snows will be somewhere west, across Schuylkill, Lebanon and Lancaster counties.
