 .AVIATION /20Z FRIDAY THROUGH WEDNESDAY/...
Low pressure developing over the area late this afternoon pulls away 
to the north and northeast tonight. Weak high pressure off to the 
west builds closer during Saturday.

Mainly LIFR and IFR conditions into at least a portion of the early 
evening for KLGA and KJFK. LIFR conditions will be mainly due to low 
ceilings mainly for the eastern city and coastal / eastern 
terminals. After 22z generally IFR is expected to prevail, except 
for eastern terminals where LIFR will linger longer until about 03-
04z. Thereafter mainly MVFR prevails later at night. Conditions will 
then improve to VFR towards 07-09z for the city terminals, but later 
Saturday morning (mainly just after the morning push) for the more 
eastern and northern terminals (KSWF, KGON, KISP).

Have removed TSRA PROB30 group for KGON as the LLJ embedded 
convective related activity is translating further east and 
offshore. Some lingering showers and vicinity showers this evening 
into a portion of the overnight, but prevailing showers are 
generally not expected. The exception to this is for KGON into the 
evening push as there will be lingering showers out to the east.

For this evening the low pressure system moves northeast with winds 
in its wake becoming W or NW and increasing in speed into Saturday 
morning.
