(CNN)Confidence is growing that a winter storm with the intensity of a hurricane, snow measured in feet and blizzard-like conditions will impact major Northeast cities this weekend.”The models continue to show a nor’easter with blockbuster potential for the weekend, mainly late Friday through Saturday,” CNN meteorologist Brandon Miller says.There are still questions about how much snow will pile up and how extreme winds will get.

“Heavy snow is most likely in parts of New England,” the Weather Prediction Center said Wednesday morning. “Heavy snow is still possible farther south along the East Coast, including the major I-95 metropolitan areas from New York City to Washington DC, but that is more uncertain at this time.”

Other NWS offices have yet to issue watches due to the uncertainty.

The storm is expected to form in the Atlantic Ocean just off the coast of Georgia, then rapidly strengthen — a process known as bombogenesis — overnight Friday and track Saturday up the East Coast.”Guidance indicates potential for this storm to undergo bombogenesis, meaning its central pressure drops at least 24 mb in 24 hours,” the Boston weather service office said earlier, referring to the unit of pressure known as millibars. “This creates a very tight pressure gradient, meaning strong, potentially damaging winds will accompany the snow.””This storm is likely to strengthen at a rate, and to an intensity, equivalent to only the most powerful hurricanes, so the high-end potential of this storm cannot be overstated. But with nor’easters, like in real estate, it will all come down to location, location, location,” Miller said.Bookmark this page for National Weather Service snow forecastsUncertainty in the forecast is pretty common more than 48 hours before a storm even has formed, as the Boston National Weather Service office noted Wednesday on Twitter.”Well, the average model error at this time range (3 days out) is over 150 miles! For example, where will the rain/#snow line setup? 150 miles could range from Cape Cod, MA to New Haven, CT. Hence, still too early.”Both forecast models predict this strengthening, but their storm tracks up the East Coast are different, changing what people could expect from Washington, DC, to Boston.

The American model (move bar to the left) shows less snow due to the storm tracking farther from shore, while the European model (move bar to the right) indicates more snow across the region due to a storm track just offshore.Compare forecast models and delay information“For those that have been following along, I know you’ve heard it repeated to death, but the key message continues to be the same: guidance is trending favorably for a big storm, but the exact track remains uncertain,” the Boston office said. “This track is what will tell us exactly where the greatest snow, wind, and coastal flooding concerns are.”A “farther offshore track of the low will decrease snow amounts while a track closer to shore will increase snow amounts and if the low gets close enough to the coast, a wintry mix will be possible for some eastern coastal sections (This is looking less and less likely),” said the New York office of the National Weather Service.

“Today’s trends will certainly be important,” the weather office in Philadelphia said. “Sampling will be steadily improving, and ‘big picture’ model solutions should start converging in the next 12 to 24 hours.”In layman’s terms: We will know more details Thursday.
