 .AVIATION /22Z SATURDAY THROUGH THURSDAY/...
A cold front gradually moves through the area this afternoon through 
Sunday morning. High pressure builds in Sunday night.

A line of showers and thunderstorms is moving slowly east across the 
forecast area, affecting the metro terminals as of 20-22Z. This line 
will continue to move east through the afternoon and evening 
affecting the other more eastern terminals towards 20Z to around 
22Z. IFR to MVFR conditions are possible in any 
showers/thunderstorms. After about 22Z-23Z lingering the threat for 
thunder diminishes for the metro terminals, but an isolated 
thunderstorm is still possible through 00-01Z. The line is expected 
to weaken as it pushes east, so as it reaches KGON, the chance for 
thunder is lower but still possible, so PROB30 added for this 
possibility. Wind gusts associated with any thunderstorms diminish 
as the line moves east this evening.

Southerly flow continues today at 10 kt to 15 kt, with gusts 20 to 
30 kt. As the front approaches later in the day and early evening 
look for a wind shift, especially in any thunderstorms to the NW. 
Additionally, gusts of 30 to 40 kt (or higher if storms become 
severe - generally across NE NJ and Lower Hudson Valley) are 
possible with any thunderstorms and added gusts of 30 to 35 kt 
within the TEMPO groups for the +TSRA. Otherwise, with the boundary 
settling nearby the winds likely go variable in direction late in 
the TAF period for the city terminals this evening.

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

There remains some uncertainty with the timing of the arrival of 
showers and thunderstorms this afternoon with amendments becoming 
increasingly likely late in the day and into the evening.

Gusts of 30 to 40 kt are possible with any of the stronger 
thunderstorms today. If storms become severe gusts around 50 kt are 
possible. Higher chances for severe are with KEWR and KTEB. 

Start time of wind gusts may be off an hour or two.

.OUTLOOK FOR 00Z MONDAY THROUGH THURSDAY...

Sunday night: VFR.

Monday and Tuesday: VFR.

Wednesday: Potential for MVFR in -SHRA.
 
Thursday: VFR.
