LATEST STORY ON SANDY:
Sandy to Take Aim at New England, Mid-Atlantic
A major storm with damaging consequences is still on the table from Norfolk to New York City and Boston. However, multiple components have to come together for the perfect storm.
The realm of possibilities continues to range from Sandy escaping out to sea, with nothing more than blustery, much cooler air sweeping in, to a dynamic storm turning inland packing coastal flooding, flooding rainfall, high winds, downed trees, power outages, travel mayhem and even Appalachian snow.
From a weather map standpoint, the worst-case scenario is for Sandy as a hurricane or hybrid storm to be captured as chilly air and strong upper-level winds join in from North America. Meteorologists refer to this as an atmospheric "bomb."
People from eastern North Carolina to Maine and Nova Scotia need to keep their guard up in case the worst-case scenario occurs.
An example of such an event includes 1991's Perfect Storm. However, as bad as it was, the worst of it remained offshore. Other October storms with a real bad attitude, which hugged the coast, were 1878's Gale, 1923's unnamed storm and 1954's Hazel.
If the assumption that the storm turns inland is correct, the worst conditions would be near and well northeast of the storm center as it moves inland. This is where the strongest winds, heaviest rain and greatest storm surge would be due to the onshore flow of high-speed moisture.
For example, a storm with hurricane strength turning inland over New York City would have tremendous impact from New York to Boston and inland to Albany, but there would likely be a sweep of dry air, gusty offshore winds and minimal concerns farther south from Philadelphia to Washington, D.C.
There is a another scenario that is more common. Quite simply, tropical systems and non-tropical systems do not like to join forces very often. In this case, Sandy would be more of a side show.
This scenario would generate a more common nor'easter nearby but offshore with significant, but far less-damaging impact. In this case, Sandy itself would not be drawn in but would escape out to sea and some of its moisture would feed the storm. Drenching rain, gusty winds and minor flooding problems would focus on New England and neighboring Canada.

Regardless of the scenarios, a sure bet with the weather pattern this weekend into early next week will be the northward spread of rough surf and rip currents along the Atlantic coast and building seas offshore. Seas offshore would reach 30 feet or higher in the proximity of Sandy.
With the center of Sandy forecast to stay east of Florida, the worst effects will concentrate over the Bahamas and eastern Cuba through the end of the week. However, some downpours, gusty winds and big surf will pound the Atlantic side of the Florida Peninsula.
The Big Four Ice Caves area is closed until further notice while search and rescue teams assess the area for recovery of the deceased victim, according to the sheriff's office and the U.S. Forest Service.
Temperatures may even make a run at 100 F by the end of the weekend, something that hasn't been seen in Dallas so far this year.
Temperatures will be seasonable, near 90 F, with plenty of sunshine and humidity, AccuWeather Meteorologist Edward Vallee said.
Temperatures will struggle to reach 70 Wednesday, then remain in the 70s through the end of the work week.
A 32-year-old Marine was hospitalized on Saturday, July 4, after being bitten by a shark near Surf City, North Carolina, WITN-TV reports.
Following a dry end to the holiday weekend, showers and thunderstorms will quickly return to the Northeast and increase in number through Wednesday.
Harrisburg, PA (1936)
Heat wave sent temperatures past 100 degrees and as high as 110 degrees nearby. Hundreds felled by heat stroke.
Northern New Jersey (1976)
Two tornadoes ripped through heavily populated area of northern NJ, skirting the Statue of Liberty and the 11 tall ships at anchor for the Bicentennial celebration. One of the tornadoes lasted nearly 8 minutes before it dissolved back into a thunderstorm. Only 3 people were injured, but property damage ranged from overturned tractor trailers to torn roofs and entire walls ripped away from buildings. Another funnel cloud was reported near Coney Island (Jersey City was the hardest hit.)
Glacier Nat'l Park, MT (1981)
10 inches of snow.
