.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 /06Z MONDAY THROUGH FRIDAY/...
High pressure moves over and eventually to the south of the region
during the TAF period.

Dry conditions through the TAF period. Aside from some areas of
fog/stratus, VFR conditions are expected. These areas of fog/stratus
will be mainly north and east of NYC terminals for late at night
into the early morning hours. Within the fog/stratus, mainly IFR to
LIFR conditions can be expected with brief VLIFR possible as well.

Winds are expected to remain at or under 10 kts through the TAF
period. Variable wind direction into this morning will eventually
become more southerly thereafter through the remainder of the TAF
period.

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

IFR to LIFR possible this morning mainly in window of 08-12Z with
fog/stratus.

Some fluctuation between categories is quite possible into early
this morning.

Chance that KJFK fog and stratus this morning does not develop.

.OUTLOOK FOR 06Z TUESDAY THROUGH FRIDAY...

.Late Tonight: Mainly VFR, but chances for IFR/LIFR in fog/stratus
east of NYC terminals, more likely at KGON.

.Tuesday: Mainly VFR, but chances for IFR/LIFR in fog/stratus east
of NYC terminals, more likely at KGON for early morning. Also, brief
localized MVFR or lower possible in late day into nighttime showers
or thunderstorms. S-SW wind gusts 15-20 kt mainly along the coast,
afternoon into night.

.Wednesday: Mainly VFR, but brief localized MVFR or lower possible
in late day into nighttime showers or thunderstorms. SW wind gusts
15-20 kt mainly along the coast, afternoon into evening.

.Thursday: VFR.

.Friday: Mainly VFR, but chances for MVFR or lower with chances of
showers and thunderstorms, especially towards the evening. Some SW-
NW wind gusts 15-20 kt are possible.

.MARINE...
Patchy fog is forecast across all waters into this morning.
There is marine dense fog expected for the waters surrounding
Eastern Long Island into this morning with a marine dense fog
advisory in effect until 9AM Monday.

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.
