Synopsis
High pressure moves offshore tonight. A cold front approaches
from the west Tuesday and passes through Tuesday night into
Wednesday morning. High pressure builds in behind the cold
frontal passage on Wednesday and remains in control through the
end of the week with a much drier and cooler airmass.

Near term until 6 am Tuesday morning
Convection entering NW nj has weakened considerably over the
last hour, so will just run with a slight chance for a shower
through around midnight across the NW interior. Other scattered
convection exists further south across SE pa and this will have
no impact on our region. There is a new shower developing
across NE pa, so will have to watch for any new development
overnight as a mid- level shortwave moves in, but at this time
will continue with a dry forecast after midnight.

Otherwise, high pressure will continue moving offshore. Low
temperatures will be in the upper 60s and lower 70s, and it will
be muggy with dewpoints around 70.

Short term 6 am Tuesday morning through Tuesday night
The shortwave should still be over the tri state area during the
morning, so cannot completely rule out a shower storm during this
time. In the afternoon, subsidence behind the shortwave will work
against convective development. A surface trough over the interior
could still provide a focus for convergence. Will go with a slight
chance to chance for showers and storms, with the higher chances
over the interior. Some thunderstorms may be strong to marginally
severe with bulk shear of about 30 kt and sufficient CAPE values
forecast.

850mb temps are forecast to be around 18-19c which should translate
to high temperatures in the low-mid 90s for the typically warmest
spots across the city, NE nj and adjacent areas given the expected
cloud cover and wind flow. With winds at a southerly component and
850mb dewpoint temps forecast at mostly 14-17c, chances of mixing
out and having surface dewpoints drop more than a degree or two in
the afternoon are slim. Heat index values are therefore expected to
range in the 90s to around 100. With Wednesday's heat index values
expected to fall short of all advisory criteria, will issue a heat
advisory for the 1-day heat index criteria of 100. Will go with the
advisory over the city, southern westchester county and parts of ne
nj.

A cold front moves into the region Tuesday night with better chance
of showers and thunderstorms across the area. CAPE will drop due to
the loss of daytime heating but lift and shear increase ahead of the
front. Strong to marginally severe thunderstorms will be possible
once again. The steering flow should be quick enough to mitigate
chances of flash flooding, but with high moisture content around,
minor nuisance urbanized flooding is possible.

There is a high risk of rip currents at all atlantic ocean
beaches on Tuesday.

Long term Wednesday through Monday
The cold front will slowly push east of the area on Wednesday with
lingering showers and perhaps a few embedded tstms mainly across the
eastern half of long island and southern ct. Skies clear Wed evening
with a much cooler airmass arriving.

Canadian high pressure builds into the region Thursday through early
next week, providing dry and sunny conditions. Temperatures will
remain below normal as highs only reach the 70s to near 80 each day.

There could be some isold showers tstms on Sunday as an upper trough
moves through the northeast. Most model guidance has the upper level
energy passing to the north of the CWA so have not included in the
current forecast, however this may change in subsequent
forecasts.

Aviation 02z Tuesday through Saturday
MainlyVFR through the TAF period. An isolated shower or tstm
is possible early tonight from the nyc metros north west.

Bigger forecast problem centers around late night reductions in
cigs vsby. Think kisp kgon kswf most likely to see reductions
to at least MVFR, but cannot totally rule it out at the the nyc
metros some time between 09z-12z give or take an hour.

South to southwest winds diminish tonight, and slowly increase
tue morning. Then expect both stronger southerly coastal sea
breezes and SW inland flow Tuesday afternoon, with gusts AOA 20
kt likely.
