Second Call Forecast For Tuesday’s Crippling Winter Storm

Estimated reading time:1 minute, 55 seconds

Over the last 24 hours since our first call, guidance has trended more aggressive in terms of snow amounts for much of state Monday Night into Tuesday. The closer we get to impact, the more confidence we are having that this will go down as one of the largest March snowstorms in recorded history.

We will take a look at the NAM model to breakdown the timing. Snow will begin to overspread the area from south to north between 9 PM Monday through midnight Tuesday, below is the NAM valid 11 PM Monday night: 

By 2 AM Tuesday Morning much of the state is in steady to heavy snow, by this time driving is highly not recommended:

The snow continues to get stronger through the morning hours as the coastal low really begins to crank. Below is valid for 8 AM Tuesday Morning:

As we head into the mid-late afternoon hours Tuesday, the snow will begin to weaken and eventually taper off by the evening hours. Below is valid for 2 PM Tuesday:

Please if you have any traveling plans Monday Night and Tuesday have a plan B! Traveling during this time will be near impossible.


Timing: Snow will enter our southern counties around 9 PM Monday night and will arrive for our northern areas by midnight Tuesday Morning. Snow will be heaviest between midnight Tuesday through at least noontime. Snow will begin to wrap up from southwest to northeast Tuesday Afternoon.

Hello, my name is Josh Adams. This year I am a junior in high school in South Central PA. I have had a passion for weather since I was five or six years old, watching the Weather Channel when the average kid my age was watching cartoons. At age 11, I discovered that there is a significant amount of weather info online from knowledgeable meteorologists to weather models and everything in between. I had the privilege to take part in a group that held informational weather discussions nearly everyday. I gained a significant amount of knowledge in several months back in 2012, constantly studying meteorology for hours each and just about every day. I created Northeast Weather Action in early 2013, just after the previous winter had ended. Things were pretty slow to start, however the winter of 2013-2014 greatly helped grow the page. Several of my forecasts verified nicely across the area. I met Chris during that winter in a facebook group, and we talked often about anticipated weather events. Just before the start of the 2014-2015 Winter, I added Chris to Northeast Weather Action (now Pennsylvania Weather Action), and once again we hit several key forecasts. Chris and I are looking forward to giving you the most up to date and reliable forecasts!
