Final Call Map On Tomorrow's Clipper...Big Storm Looming For The Weekend?

No surprise here, a Clipper is on its way to deliver a light snowfall for many of us. Over the last 24 hours, I am becoming increasingly concerned that rather our area see a period of light steady snow, we see a line of squalls form. These snow squalls may deliver blinding snow for a period of 10 to 20 minutes then it is gone. If your local town receives one of these intense snow squalls, there is no doubt in my mind areas may over-perform in terms of accumulation. It is simply a wait and see game to see who gets what at this point.

The latest NAM model shows the line of squalls forming to our West quite well.

Timing: The timing has sped up a little bit. Some light snow showers are possible between 10 AM and 2 PM. A heavy Snow Squall line may whip through the area between 2 PM and 6 PM, deliver with it our accumulating snow.

There is still a chance that the mountains "eat up" a lot of the precipitation before making it to Dauphin County, however I still think enough squalls survive the mountains for many of us too see flakes flying in the air. For my final call map, I trimmed the Coating to 1 inch area a bit on the southern edge. Nothing else has changed.

Yes folks, there will be a big storm this weekend. As of right now, it is an all rain event for everyone in PA..that is how I see it at the moment. Timing would be Saturday Morning through Saturday Night. Here is the setup.

In the picture below, you will a low pressure cut up through the Ohio Valley, this low pressure then dies out and reforms a second low off the coast of Jersey, then heads Northeastward from there.

In order for our area to see snowfall, we want the primary low cutting up through the Ohio Valley to die out over the state of Kentucky, then transfer off the coast of Southeast Virginia. If this occurs, which is not looking likely at the moment, a significant snowfall would be possible across the Mid-State.

We still have a good 4 days for this storm to trend colder, but as of now it is another rain maker. So snow lovers, make sure you appreciate every flake that falls Tomorrow...keep your fingers crossed for the weekend.

Thanks in advance. -Chris
