NEW YORK — A spooky storm system moves into the region Thursday, making for a gloomy Halloween. There is hope that the rain will take a turn to the light and drizzly side as trick or treaters head out. The rain will be back though, and it may come down heavy overnight.
Ahead of the storm, a strong southerly flow developed Thursday morning. That pushed water along parts of the south shore of Long Island. Together with an astronomical high tide, a Coastal Flood Advisory was in effect from 8 a.m. to 1 p.m. on Thursday.
Most of the heavy rain will develop overnight Thursday into Friday, as a cold front approaches. Winds will kick up Thursday night with gusts up to 50 mph before the front moves through. As a result, a Wind Advisory has been issued for all of Long Island, including Brooklyn and Queens, as well as New England. The advisory will be in effect from 8 p.m. to 6 a.m. Friday.
As mentioned, the winds will start to kick up as the cold front approaches. Rain will return late at night and it will become heavy and possibly feature a rumble of thunder. Flash flooding cannot be ruled out as the line of heavy rain and thunderstorms cross through. As much as an inch of rain will be possible by the time it tapers off at daybreak Friday morning.
The winds will start to back down and skies will clear out early on Friday, but it will still be rather breezy. A stiff northwesterly wind will bring keep temperatures in the upper 50s in the morning, then fall into the 40s during the afternoon.
The weekend will feature a lot of sun through the period. Temperatures will be rather cool with highs in the low to mid 50s, but it will be optimal for the runners on Marathon Sunday.
