Synopsis
A warm front moves north of the area today. High pressure remains
anchored over the western atlantic through mid week as a slow moving
frontal system approaches from the mississippi valley into
Wednesday. A cold front moves across Wednesday night. A series
of lows will be moving through the northeast late this week into
the weekend.

Near term through tonight
Visibilities have improved across the region with many locations
2 to 3 statute miles. Local spots across southern connecticut
and long island were still around 1 4 mile, however,
visibilities will be improving as mixing continues. Clearing
was occurring with low clouds mixing out with a high cirrus
deck. There remains some uncertainty as to how much clearing
will occur along the coast where the inversion will be strongest
from the cold ocean temperatures. Low clouds could hang on
there for much of the day.

An unseasonably warm air mass continues to move into the region
today as a warm front moves north of the region. The warmth
will be a result of an unusually strong ridge across the western
atlantic.

Short term Wednesday
Areas of fog and patchy drizzle are expected to redevelop from
se to NW across the region tonight. Uncertainty exists in the
extent coverage of the fog, but think dense fog is a
possibility. Will highlight this potential in the hwo. It will
be very mild for this time of year with temperatures only
falling into the upper 40s and lower 50s.

The warmest day of 2018 so far is expected on Wednesday. This
is when the ridge along the western atlantic is at its strongest
with heights around 595dam at its core, which is more typical
of what is seen during the late spring and summer. Height
anomalies across the eastern us are around 3 standard deviations
above normal for this time of year as well.

The day will start with fog and low clouds, but improvements should
occur after sunrise with strong heating and better mixing than on
Tuesday. Patchy fog and low clouds could persist into the afternoon
near the long island south shore and SE ct.

The forecast high for central park is 70 degrees, which is the
normal high temperature for early may! Record highs are once
again expected on Wednesday with forecast readings in the
middle 60s to lower 70s for most locations. Cooler temps in the
upper 50s and lower 60s can be expected near the coast.

Long term Wednesday night through Monday
An active weather pattern will last through the upcoming
weekend. A southeast ridge will help steer a series of low
pressure centers to our north, but associated warm and cold
fronts will provide lift and a focus for moisture convergence
around the tri-state area. While there will be chance for rain
for just about every day and night period from Wednesday night
through Sunday, it won't be raining most of this time. Looks
like the best overall chances occur Thursday afternoon, Friday,
and Sunday. Saturday could actually end up dry for everyone, but
will leave in lower-end chances for rain for now. Frozen pcpn
would be possible inland Thursday night into Friday morning as
an elevated layer of above-freezing temperatures coincide with
low-level cold air filtering in from the northeast. Looks too
warm for snow, so sleet and freezing rain would be possible.

Still, pops are on the lower side during this period. High
pressure then builds in from the west on Monday with dry
weather.

Temperatures through the long term will be above normal with highs
mostly in the mid 40s to lower 50s

Aviation 16z Tuesday through Saturday
A warm front lifts north of the terminals today as high
pressure remains anchored over the western atlantic.

Visibilities have improved for nyc terminals to ifr with coastal
terminals still at lifr. Gradual improvement will continue into
the afternoon for nyc nj and NW terminals, possibly improving to
vfr this afternoon. Coastal terminals may remain ifr all day
with little improvement. Improvement time could be forecast 1 to
2 hours too early. Lifr vlifr conditions likely to develop this
evening once again. These lower conditions continue all night.

S SW winds with gusts to 20 kt possible for kewr kteb klga kswf.

Late day S 15g20 kt coastal jet development possible for jfk
into lga. Elsewhere occasional SW gusts of 15 to 20 kt possible.

S SW winds subside to 10 kt or less this evening and continue
overnight.
