No significant changes. && .KEY MESSAGES... 1) Tranquil weather with slightly below normal temperatures and lower humidity will continue into the weekend. 2) A frontal system will bring our next chance at unsettled weather Monday night into Wednesday. && .DISCUSSION... .KEY MESSAGE 1... High pressure over the Northeast today will push offshore this afternoon, providing continued dry conditions, slightly below normal temperatures (up to 5 degrees below normal) and lower humidity levels. With the weak pressure gradient the winds will remain fairly light. High pressure drifts northeast into the weekend as an upper level trough from Canada approaches. Dry weather will continue. Weekend high temperatures will remain in the upper 70s to mid 80s. .KEY MESSAGE 2... An amplifying trough sets up over the eastern US Saturday night. A couple of low pressure systems will ride a frontal boundary well offshore, with no impact to the area Monday morning. Another shortwave approaches from Ontario on Monday, bringing a frontal system and possibly a low pressure system through from Monday night into Wednesday and possibly lingering into Wednesday night. This frontal system will bring unsettled weather with showers and thunderstorms expected. Exact impacts and timing are still uncertain given differences in guidance at that time range. && .AVIATION /12Z FRIDAY THROUGH TUESDAY/... High pressure resides over the area throughout the TAF period. VFR. Light to calm winds become light out of the NE this morning, then shift SE-S 10 kt or less in the afternoon.

E wind develops during Saturday morning. ...NY Metro (KEWR/KLGA/KJFK/KTEB) TAF Uncertainty... No unscheduled amendments expected. .OUTLOOK FOR 12Z SATURDAY THROUGH TUESDAY...
