 .AVIATION /06Z FRIDAY THROUGH TUESDAY/...
A frontal system will remain stalled across the area into Friday
as a series of frontal waves track along it. The front will be 
dragged east in the afternoon and early evening as low pressure
lifts northeast of the area.

Outside of any showers the first half of tonight, expect mainly
VFR conditions with pockets of MVFR/IFR. Ceilings and 
visibilities will lower late tonight and into early Friday
morning as showers increase in coverage as low pressure 
approaches from the Mid Atlantic states. Expect widespread IFR 
with pockets of LIFR on Friday with showers and embedded 
thunderstorms. The better chance for thunderstorms will be 
across the terminals east of NYC, where there is PROB30 18Z-22Z.
Given recent trends to have the center of the low passing nearly
overhead the NYC metro, opted to include a PROB30 for TSRA for 
KJFK and KLGA from 14-18Z. Conditions will then begin to 
gradually improve from west to east during the late afternoon 
and evening hours. 

Winds will become NNE/E at 10 kt or less tonight, then become
more easterly around 10 kt at the coast on Friday. NYC and LI
terminals could become SE for time in the late morning/early
afternoon Friday. There also could be a few gusts 
15-18kt at the coastal terminals. By Friday evening, the 
frontal system moves northeast with winds in its wake becoming W
or NW and increasing in speed into Friday morning.

...NY Metro (KEWR/KLGA/KJFK/KTEB) TAF Uncertainty...

Amendments likely through Friday night with changing flight 
categories and wind shifts. Winds could go SE late morning/early
afternoon, especially at KJFK. A few gusts 15-18kt possible.

There is low chance for thunderstorms generally from 14-18Z for
KJFK and KLGA. Confidence is too low at this time to include in
TAFs at KTEB and KEWR.


.OUTLOOK FOR 06Z SATURDAY THROUGH TUESDAY...

Friday Night: MVFR/IFR in showers, mainly the first half of the
night. Gradual improvement overnight.

Saturday: Mainly VFR, except MVFR or lower possible isolated showers.

Sunday through Tuesday: VFR.
