Wednesday’s winter storm will start to move into the area in early afternoon. Into Philadelphia by 1pm, Trenton by 2pm and Shore Points by 3pm
Snow amounts will be significant near and north and west of the I-95 corridor. Snowfall rates could reach 1 to 2 inches per hour for a time late day Wednesday into Wednesday night, causing significantly reduced visibility and potentially crippling travel impacts in places. One of the big impacts are that we could see winds 15-30mph with gust over 40mph at times, these winds will increase the chances for power outages in the area. If you will be traveling tomorrow afternoon/evening prepare for major travel delays due to this being the first snowfall and major snowfall of the season in some areas. Make sure you have a full tank of gas, phones charges, shovel and blankets in your vehicle.
As you can see below is our final call map for the upcoming Winter Storm.
Green- Shore points and those along the coast might see a few snowflakes mixing in but mainly rain.
Light Blue- Mix/Rain for majority of the storm
Dark Blue- Snow to Mix then back to snow. These areas will see very sharp cutoffs within the same county at times. Also the wildcard area, if the storm moves southeast as we started to see with the 18z nam. This could be all snow and areas could see over 12″ but at this point we do not feel that is going to happen. Higher amounts on map are for higher locations within that area. Locally higher amounts possible.
Purple/Blue- All SNOW
NOTE: A shift by 10-20 miles either north or south will impact totals.
A Winter Storm Watch will go into effect at 10am until 10am Thursday. Snow will begin to move into the area this afternoon. Tonights afternoon rush hour will be a mess.

PRECAUTIONARY/PREPAREDNESS ACTIONS...
If you must travel, keep an extra flashlight, food, and water in
your vehicle in case of an emergency.
The latest road conditions for the state you are calling from can
be obtained by calling 5 1 1.
Temperatures falling near or below freezing combined with moisture
near the ground may result in patchy black ice developing. The
greatest risk is in sheltered areas and valleys and on elevated
surfaces. The risk should diminish later tonight as winds
increase and drier moves into the region.
Motorists should drive with extra caution this evening. This is
especially true if roads look wet, as they actually may be icy
instead.
A Winter Storm WATCH is in effect starting at 10am Wed.
Incase you didn’t know, its going to snow this week. This is something we have been talking about for the past few days, expect major to significant impact from the Nor’easter on Wednesday. At this point we are confident this storm will begin around midday/early afternoon on Wednesday and continue until early Thursday AM.
Areas near i95 will see some sleeting and mixing. We are sorry to say, but the shore points it’s mostly rain for you. The rest of the area will see significant snowfall (some areas could peak over 16” plus of snowfall). We expect the NWS to upgrade the current Winter Storm Watch to a Warning. Once that happens we will pass that information along. I will be issuing our final call map tomorrow afternoon if needed.
Our map below you will see it has a lot of different totals on it for the areas.
Purple – 12-16”+ Dark Blue Mostly 8-12+” (some areas could see higher amounts. Closer to i95 could see lower due to mixing issues) Light Blue – C-2” Green -All Rain

more inches possible. Winds could gust as high as 30 mph.

northern Delaware along and near the I-95 corridor.

* IMPACTS...Travel could be very difficult. The hazardous
conditions could impact the morning or evening commute.

Wednesday morning and some areas in the watch may mix with sleet
and rain. We anticipate there will likely be a sharp gradient in
snow totals depending on precipitation type.

UPDATE: A WINTER STORM WATCH HAS BEEN ISSUED FOR WED MORNING until Thursday at 7am.
As we are following the developments in the major winter storm coming on Wed. Here is what we know now. Please NOTE the totals are the map below are just the chance of seeing that much snow. Tomorrow we will release a map with more total information.
We are gaining more and more confidence in this major winter storm that will start early afternoon on Wednesday into Thursday morning. While a lot of areas could see snowfall totals over 12″ and 16″, you have to note we are paying close attention to see how close the snow/rain mix line will set up near i95. The shore points at this point we feel will be mainly rain!
What will we see: Significant Snow- Locations seeing over 12″ are very possible. Gusty Winds Power Outages Travel Impacts during the Wed afternoon commute.
Here is our first call map. We are keeping a close eye, be prepared for changes to this map come tomorrow afternoon. We also expect the NWS to issue Watches as early as tomorrow afternoon for some areas.
While we are keeping an eye on Wednesday, we have to talk about Monday first. The latest model runs are showing some accumulation snow along i95. The models pictured below are the first of the night runs. We are going to be keeping an eye on this. Please NOTE this is NOT a forecast nor what you are going to get in your backyard. We are sharing this to point out that a threat is possible.
If this is to verify we would expect to see watches and advisory issued over the weekend. Our team will bring you the latest on these developments over the weekend.
