For this same time period, there is low probability for some thunderstorms, too low to include in TAFs at this time. Also there is a low probability for sub VFR arriving towards the tail end of the 30 hr TAF period for KJFK and KLGA, but confidence in occurrence remains too low to include in TAF at this time.

Some of the interior terminals will settle in with wind speeds closer to 5 kt or less at times overnight as the winds become more variable in direction. Otherwise a southerly flow at 5 to 10 kt will prevail overnight for most city and coastal terminals. During late Wednesday morning into the afternoon a S flow becomes more SE, especially later in the afternoon. ...NY Metro (KEWR/KLGA/KJFK/KTEB) TAF Uncertainty...
