This morning the NWS has issued Winter Storm Watches for parts of the area. The Winter Storm Watches are for the i95 corridor in our area. We will see sharp cut offs to the west. You can view the latest NWS alerts on our webpage at https://greaterphilaseverewx.com/active-alerts/

The winds will be a MAJOR issue and we could see power outages. If the models continue to forecast these high winds don’t be surprised if Blizzard Watches/Warnings are issued for locations down the shore.

The overnight models have came back to the west and currently the GFS is the outlier with most of the models coming back west, the CMC is the furthest west. While these are not forecast below they are what the models are showing.

Here is the last 2 NAM forecast runs.

Last Nights Model Runs

At this hour confidence is continuing to grow that parts of the east coast will see a major winter storm. This storm is capable of bringing feet of snow to some and blizzard conditions. This storm will impact most major cities on the east coast. The models continue to show a nor’easter with blockbuster potential for the weekend, mainly late Friday through Saturday, We still can’t answer how much you will get in your backyard, so please don’t ask! We will see snow but how much is the big question.

At this time this is our thinking. Our map shows who has the best chance of seeing less than 3″, more then 3″ and greatest chance for seeing over 6″.

At this time the i95 corridor around Philly we are looking at 3-6″ but any trend west will increase those numbers and any trend will decrease those numbers. Currently we are seeing a east trend. We hope to have those numbers somewhat finalized by tomorrow afternoon. Our second call map WILL have localized snow totals.

While we are not set on the snowtotals at this time, we do feel confident in saying who we feel will see at least those numbers above.

Now what the models are showing:

The latest Euro showing 6-18+ inches of snow depending on location. These totals cut down the further east you get.

So after this afternoons Euro run, the GFS and NAM look like they want to join in on the fun. While the GFS and NAM are not showing totals that the Euro did, they are showing a potential major winter storm for Baltimore to Maine. At this point confidence is growing but not locked in 100% just yet. This afternoons trends are HUGE for team snow.


Also we are seeing the “B” word being thrown around, we are not going to throw that out just yet. Someone along the East Coast could see those conditions. If we keep seeing these trends tomorrow afternoon it will be time to prepare for significant storm. Until then we will bring you updates throughout the night and into tomorrow.

At this point timing looks to be Friday afternoon until Saturday afternoon.

The 18z nam which is OUT of its normal range is painting a picture that lines with this afternoons euro run. While we the nam is out of range it does look very good for snow lovers. We will have an update tomorrow on the NAM once it gets into its range.

The GFS has moved a bit west which is great for snow lovers. We are going to keep a close eye on this to see if it catches up with the Euro/NAM.

We have added new features to our website, check them out in the menu bar above!

At this hour confidence is increasing that the east coast will see a winter storm late Friday into Saturday. While the track remains uncertain at this time who will see what, it has peaked out interest to really track and see what comes of it.

The potential that this storms brings significant winter weather to someone along the east coast is possible. Our team will be following this storm carefully and we will bring you updates as it gets closers. DO I think this might be our storm #TeamSnow? I am not sure yet but I like what I am seeing.

We will provide updates throughout the next day or so until this winter weather event.
