 .AVIATION /02Z THURSDAY THROUGH MONDAY/...
High pressure gives way to an approaching cold front overnight that 
slowly moves across the terminals on Thursday. The front is likely to
push to the south Thursday night.

VFR through Thursday morning. Showers and thunderstorms are possible 
for the afternoon and early evening. PROB30 groups for TSRA are in 
place for the NYC terminals beginning at 18z Thu and carry through 
to about 01z Fri. Probabilities are lower for thunder at KSWF, KHPN, 
KBDR, and KGON, so have just gone with a PROB30 for SHRA at these 
more northern terminals. Otherwise, RA should prevail by the start 
of the Thu evening push and taper towards 02-03z Fri for the city 
terminals.

Winds light mainly under 5 kt overnight. Winds should then become 
N-NE Thursday morning and remaining light. The flow likely remains 
weak on Thursday, thus winds may vary from some from TAFs at times. 
Winds likely shift more N and NE Thursday evening. 

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

Adjustments likely for timing of TSRA potential Thursday afternoon 
and evening. The PROB30 may need to become a TEMPO if confidence 
increases.

Low confidence with wind direction on Thursday, but speeds remain 
light.

.OUTLOOK FOR 00Z FRIDAY THROUGH MONDAY...

Thursday night: MVFR or lower possible in showers and t-storms 
during the early evening. Highest chance for thunderstorms are NYC 
metro and Long Island during the first half of the evening. 

Friday: Mainly VFR. Low chance of showers with MVFR or lower.

Saturday: Chance of showers with MVFR or lower at times.
Thunderstorm possible in the afternoon/evening.

Sunday: Chance of showers, possibly a thunderstorm, with MVFR or 
lower at times.

Monday: VFR.
