Storm Potential on East Coast Starting This Weekend

One or more storms maturing over the Plains have the potential to spin off new storms along the Atlantic Seaboard bringing a chance of snow to some areas this weekend into next week.

The pattern we are entering will create an atmospheric roadblock for storms moving from the Plains and bring warm air bodily northward.

The pattern is referred to as an Omega Block by meteorologists, because steering winds high in the atmosphere, known as the jet stream take on the shape of the Greek letter Omega.

In a simple sense, the pattern allows cold air to sneak in or hold its ground more than what you might expect and could open the window of opportunity for snow along part of the Atlantic Seaboard.

Sometimes this pattern can lead to a rain changing to snow situation as the storm strengthens and draws in colder air.

AccuWeather.com meteorologists foresee two to three attempts at storm formation along the middle part of the Atlantic coast with the first system this weekend.

The form (rain versus snow), coverage and intensity of the precipitation from the storms at the local level are uncertain at this time. The storms have not been birthed yet and are still days away. The question is not so much will they form, but how close to the coast will they track and how strong will they become.

However, for those desperate for snow, the short-lived pattern may offer the best chance at significant snowfall for areas from Washington, D.C., to Philadelphia and other areas in the mid-Atlantic that have seen so little this winter.

It could also mean more heavy snow for some locations that have been hammered by heavy snow in recent weeks, such as Long Island and New England.

The details will unfold over the next few days.

For now, you can talk turkey like a weather pro around the dinner table by mentioning that an Omega Block could lead to snowstorms along the East Coast this weekend into next week.
