-- Changed Discussion --

-- Changed Discussion --
The cold front has still yet to pass through SE CT and eastern LI as of nearly 03z. Expect only low chances of showers right along the front for the next few hours, with dry conditions for the overnight. A much drier air mass will ensue with the winds switching NW to N. Dewpoints will fall quickly through 60s from NW to SE across the area. By the pre-dawn hours look for dewpoints to get into the middle and upper 50s with a more refreshing and comfortable feel into Monday morning with gusts of 15 to 20 mph in places.

&& .SHORT TERM /6 AM MONDAY MORNING THROUGH TUESDAY/... During Monday expect a pleasant early summer day. Dewpoint readings should remain primarily in the 50s with temperatures a few degrees below normal with upper 70s to lower 80s for the afternoon. With the strong synoptic flow out of the N there is little chance for sea breeze development. Forecast soundings indicate some scattered cloud development in the 5 to 7 kft level with any daytime heating towards the late morning and afternoon. Otherwise expect a partly to mostly sunny day with a refreshing breeze out of the N. The pressure gradient relaxes Monday night with high pressure starting to settle just west of the area. With light winds and likely just a few clouds around 5 kft expect some radiational cooling across outlying areas. Temperatures should be able to fall into the lower and middle 50s in the coolest spots, with lower to middle 60s for the metro and along much of the coast. && .LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/... No major changes were made to the Long Term and closely followed the NBM. High pressure will remain in control Tuesday and Wednesday before shifting offshore Wednesday night as a warm front lifts to the north. A cold front will follow, but will likely not move through the area and may remain to our north into early next weekend. Will have to watch the evolution of any middle level impulses as they ride along the periphery of the ridge. These are difficult to resolve at this time range, but they may be a focus for showers and thunderstorms. Right now the consensus of the modeling indicates a bit higher probability on Friday and potentially Saturday compared to Thursday. Temperatures remain seasonable on Wednesday. The deterministic NBM has trended down a bit for the end of the week, but still should reach above normal levels, with highs in the upper 80s to lower 90s away from the coast. Similar readings are expected through Saturday. Humidity levels will also be on the rise for the end of the week into next Saturday. && .AVIATION /03Z MONDAY THROUGH FRIDAY/...

High pressure build in behind a cold front for the overnight hours and lasts through Monday. VFR. NW-NNW gusts around 20kt for the overnight, mainly for the city terminals.

OUTLOOK FOR 00Z TUESDAY THROUGH FRIDAY... Monday night: VFR. S wind gusts 15-20 kt Wednesday afternoon into Wednesday early evening. Thursday: MVFR or lower possible with any late day or nighttime showers/tstms. Friday: MVFR or lower possible with a chance of showers and tstms.

-- Changed Discussion --
SCA has been canceled with this updated with seas remaining below 5 ft. Some NW-N gusts around 20kt for the overnight hours. On Monday, high pressure builds with slowly subsiding seas with mainly sub small craft conditions, although nearshore gusts may occasionally gust near 25kt. The pressure gradient relaxes Monday night as north winds lighten and ocean seas subside closer to 2 ft towards early Tuesday morning. Sub advisory conditions will remain through at least Wednesday night for all waters as high pressure settles over the waters, then moves offshore. Marginal small craft conditions become more likely late Thursday as a southerly flow increases, with possible small craft seas on the ocean into Friday.

&& .HYDROLOGY...
-- Changed Discussion --
No hydrological impacts are expected through Wednesday. A frontal boundary and pre-frontal trough are likely to approach late Thursday into Friday, and possibly linger to begin next weekend. It remains too early to determine the risk of any hydrological impacts from this frontal system.
