Whether it was picking up the pieces in the wake of Sandy or shoveling out from record snowfall, residents of the Northeast have had to worry about the weather for Halloween the past two years.
Fortunately, a repeat of the stormy conditions in 2011 and 2012 is not in the cards this Halloween from the Carolinas to Maine.

Mild in East for 2013 Halloween; No Major Storms

One year ago this week, Sandy had begun its deadly path northward from the Bahamas. This year, the tropics have been quiet and although development could still occur in the Caribbean, impacts to the U.S. should remain minimal.
The weather pattern leading up to and including Halloween 2013 is much more favorable for outdoor activities and trick-or-treating. While not every community celebrates the holiday on Oct. 31, many locations in the East should be rain-free and certainly not stormy or snowy.
A large dome of high pressure is forecast to build into the East to start Halloween week. Mild air will spread into the East ahead of a storm diving into the Rockies, set to bring blizzard conditions to Montana.
Dry weather will hold at least into the early part of the week in the East as mild conditions build northward. It will be stormy in the Rockies.
An area of light rain may spread across the Ohio Valley and mid-Atlantic late Tuesday into Wednesday, but a widespread storm is not expected in areas ravaged by poor weather the last two years.
The forecast for Halloween in the East hinges on the speed of the storm emerging from the Rockies. At this time, AccuWeather.com meteorologists favor a slower idea, which would keep the East dry on Halloween (Thursday) after a brief wet spell the day prior. A faster storm could spell wet weather for trick-or-treating.

For those ghouls and goblins heading out to gather candy on the night of Halloween, temperatures are forecast to be near 60 in many locations from Washington, D.C., to Boston.
AccuWeather.com Senior Meteorologist Joe Lundberg noted, "three things look fairly certain, it won't be unusually cold, a repeat of Sandy is not in the offing, and snow should remain in the mid-section of the nation."

Sandy and Snowtober Snarl Halloween Plans

Memories of Sandy are still fresh for millions as the fall holiday of trick-or-treating and costume making arrives. From the devastating storm surge to widespread power outages, Sandy snarled plans from the day of landfall (Oct. 29, 2012) well into November.
Many communities postponed or cancelled Halloween and trick-or-treating due to numerous downed trees and power lines.
This historic storm was an extremely rare event and the atmosphere is not primed for a repeat.

Sandy followed a year after more than 30 inches of snow buried portions of the Northeast and broke numerous October snowfall records.
New York City even received 2.9 inches of heavy, wet snow with the "Snowtober" storm of 2011, not typical for October.
As residents shoveled out, Halloween plans were once again altered to deal with the clean-up.
The blanket of snow was caused, in part, by a fresh dump of cold air. This year, a much milder weather pattern will be in place for the East, not favoring snow.
