.KEY MESSAGES...
1) Dangerous heat is expected mid-late week.  Extreme Heat Watches
have been issued.

.DISCUSSION...
.KEY MESSAGE 1...
H5 ridging is already in the process of building
across the Gulf region as of Sunday afternoon, with guidance
projecting the ridge to build north-northeast thanks to deepening
Pacific cutoff through the coming week.  As previous forecaster
noted, heights reach 2-2.5 standard deviations above normal by
Wednesday, just as it crests near the Great Lakes.  With this ridge
in place, and a modified subtropical airmass, will be looking at the
potential for a prolonged period of dangerous heat mid to late week.

There is a bit of uncertainty with the dominant factors being
the placement/amplification of the ridge axis and as such the
moisture profile. GFS and its ensembles remain the slightly more
amplified/eastern outlier (22-24C at H8) while other extended
deterministic/ensemble guidance is not as warm along the
immediate coast. Dewpoint spreads still remain on the order of
3-6F mainly with their typical medium range uncertainty.
However, even on the lower 25th-10th percentile, dewpoints are
still in the upper 60s to near 70F over a nearly 72 hour
period.

Even with this uncertainty recent run to run consistency
support a potentially dangerous heat situation with only a few
degrees difference between potential Advisory and Warning level
heat indices Wednesday through at least Friday. The rising
surface dewpoints will also limit overnight relief. Given these
factors, have hoisted an Extreme Heat Watch for all areas
Wednesday through Friday. This could be a dangerous situation
especially for sensitive groups.

.AVIATION /03Z MONDAY THROUGH FRIDAY/...
High pressure slowly builds in through the TAF period.

Mainly VFR through the TAF period. IFR to locally LIFR
conditions are also possible tonight, especially for GON, ISP,
BDR, and JFK. These conditions, if they develop, should quickly
improve around 12-13z. There is also a chance for IFR at LGA,
EWR, TEB, HPN, TEB, and SWF, but confidence is not high enough
to include in the TAF.

SE-S winds will weaken this evening, becoming light and variable
tonight. Light flow after 12z becomes SE late morning into the
afternoon, potentially veering to the S late in the day. Wind
speeds will be 10 kt or less Monday afternoon.

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

IFR possible from approx 08z-12z Monday for KLGA/KEWR/KTEB.

Chance that IFR does not occur at KJFK, or that start/end
timing of IFR is off by 1-2 hours.

.OUTLOOK FOR 00Z TUESDAY THROUGH FRIDAY...

.Monday Night: VFR. Chance of MVFR or IFR conditions, mainly
east of the NYC metro terminals late.

.Tuesday: VFR. Chance of a showers and thunderstorms with MVFR
late in the afternoon and evening. S-SW wind gusts 15-20 kt.

.Wednesday-Thursday: VFR. S-SW wind gusts 15-20 kt in the
afternoon, especially near the coast.

.Friday: VFR. Slight chance of a shower or thunderstorm with
MVFR late in the afternoon and evening.

.MARINE...
Some patchy dense fog is expected this evening into a portion of
tonight across the nearshore waters around the east end of Long
Island. An marine weather statement was issued earlier this
evening to account for the fog. The statement may need to be
expanded or upgraded to a dense fog advisory overnight if the
fog becomes more widespread.

Conditions forecast to remain below SCA thresholds on the non
ocean waters through Thu. Wind gusts reach around 20 kt on the
ocean waters late day Tue and Wed, but should remain below SCA
criteria. Seas approach 5 ft on the ocean in a S flow late Wed
into Wed night.

Rip Currents: The rip current risk remains low Monday with 1-2
ft swell sets with period varying between 5-10 s and onshore
winds at or below 10 kt. The risk increases to moderate on
Tuesday, with south winds 10-15kts in an increasing swell.
