Trick or Treat? Halloween Weekend Forecast for Larchmont
We have a fun-packed weekend ahead. Will there be a washout? Get details including an early prediction about Tuesday evening.

LARCHMONT, NY — Halloween festivities kick into high gear as folks head to the many, many activities offered across the Hudson Valley for the weekend leading up to All Hallows Eve on Tuesday. Right now, it looks as if only Sunday will be a washout for outdoor events. Nor'easter conditions are expected in the region.
The meteorologists at Hudson Valley Weather are watching the coming storm very closely. "It’s a VERY complicated forecast that involves a strong trough of low pressure, interacting with some tropical energy from the Caribbean," said Bill Potter from HVW. "The result should be some heavy rain and high winds across the region."
The National Weather Service updated its Hazardous Outlook Friday morning, but the details were unchanged from Thursday:

The potential exists for a strong cold front to approach from the west, while an intensifying storm moves up the coast, Sunday into Sunday night. This storm could produce heavy rain capable of causing areal and small stream flooding during this time frame. Strong winds will also be possible across the area.
Conditions may never coalesce into an actual tropical storm. But it's the experience that counts.
"Regardless of official tropical storm designation or not, this storm will pack a punch in terms of the consequences of heavy rainfall and gusty winds in a large part of the Northeast later this weekend into the start of the new week," said Alex Sosnowski, AccuWeather senior meteorologist.
