3) Unsettled weather to start this weekend with below normal temperatures.
KEY MESSAGE 3
Guidance has been consistent with a frontal system sliding south of the area on Saturday and bringing rain to at least to NYC north and west. There is still some uncertainty with how far east the precip shield will get, but there will likely be a decent gradient. Regardless, the easterly flow will keep temperatures in the low 50s for most. There is some indication that eastern CT could get into the upper 50s if the bulk of precip and clouds stay farther west.
The large spread for this event lies with the amount of rain that we could see. The latest NBM 24hr QPF 10th percentile for NYC shows 0.00 inches with the 90th percentile showing around 1 inch. This is expected to fall over a 18-24 hour period so flooding is not a concern at this time.
OUTLOOK FOR 15Z THURSDAY THROUGH SUNDAY
Thursday: Mainly VFR.
Friday: Mainly VFR. Slight chance of showers with MVFR cond in the afternoon and at night.
Saturday: MVFR or lower possible with chance of showers.
Sunday: MVFR possible mainly in the morning with slight chance of showers. Low confidence.

MARINE
A LLJ translates east quickly this morning and will bring a period of 25 kt gusts to the waters from Sandy Hook to Moriches Inlet out 60 NM, the South Shore Bays, and have just added NY Harbor to the SCA as well. The waters from Moriches Inlet to Montauk out 60 NM may also see 25 kt gusts, but there is less confidence and it will likely be more occasional.
Sub-SCA conditions are then expected on all waters tonight through the weekend.
