Synopsis
A warm front will slowly move through the region through this
evening. A cold front will move across the area Wednesday and
Wednesday night. High pressure then builds north of the region
through late week, as low pressure moves along a stalled frontal
boundary south of the area. A stronger area of high pressure
builds from the west through the weekend.

Near term until 6 pm this evening
Forecast on track with just some minor adjustments to reflect
latest observations, specifically temperatures and dew points.

Otherwise, a warm front will slowly approach the area today.

Overrunning moisture will allow for light rain showers at the
start. Convergence aloft seen on the kewr radar will mean radar
coverage should increase over the next few hours, coupled with a
strengthening 950 hpa jet, intensity of the rain should also
increase and become more stratiform. The rain will become
heavy at times this morning as the jet strengthens to 35 to 45
kt.

There remains a chance for heavy rain through the early
afternoon, then the threat will decrease from west to east as
the warm front moves through and the 950 hpa jet moves away from
the region. Also, precipitable waters will increase to 2 inches
during this time frame and dew points will rise into the upper
60s and lower 70s, another indication of locally heavy rainfall
possible. Conditions have been dry lately, so despite the threat
for heavy rain, widespread flooding is not expected, with minor
urban and poor drainage flooding being the primary concern. The
weather prediction center has placed the entire tri-state in a
slight risk for excessive rainfall, so isolated flash flooding
cannot be ruled out.

There is a high rip current risk for the atlantic beaches
today.

Short term 6 pm this evening through 6 pm Wednesday
As the warm front lifts north of the region, steady rain will
transition to light showers. Eastern areas may continue with
some moderate to briefly heavy rain at times as the 950 jet may
still be in that area. Thereafter, the rest of the night should
feature a chance for light rain showers and very humid
conditions. With abundant low level moisture, patchy fog will
be possible across the entire area. Some guidance is indicating
that the fog may be dense, especially with dew points rising
into the lower 70s region-wide. However, there was not enough
confidence to include dense fog in the forecast.

A cold front will approach on Wednesday. Pre-frontal trough
associated with the front moves into the region late in the day.

Elevated instability will allow for a slight chance for
thunderstorms in the morning. As the day progresses, there will
be a better chance for thunderstorms in the afternoon. With a
very moist air mass in place and strong winds aloft, some
storms may be strong as we head into the afternoon. Gusty winds
would therefore be possible with any thunderstorms. Lifted
indices in the -2 to -4 range indicates some threat for severe
thunderstorms, especially with the cold front approaching. Some
of these storms could produce damaging winds, but right now that
is a low threat.

There is a high rip current risk for the atlantic beaches
Wednesday.

Long term Wednesday night through Monday
The cold front moves across the region Wednesday night with the
continued threat of showers and thunderstorms, some which may be
capable of producing heavy rainfall and strong gusty winds.

High pressure then builds north of the region on Thursday.

Meanwhile, the cold front stalls south of the area with an area of
low pressure expected to travel along the front, possibly bringing
another chance of precipitation to the region on Thursday night and
early Friday.

A stronger area of high pressure builds into the area this weekend,
with dry weekend expected.

High temperatures Thursday through the weekend will climb into the
upper 60s and 70s.

Aviation 12z Tuesday through Saturday
MVFR and ifr stratus will be in place with some scattering out
of ifr stratus this afternoon. Low confidence on this scattering
out occurring. Rain moves in and lasts much of the day with
heavy rain at times. There will be a lull in the rain tonight,
with leftover low moisture resulting in likely ifr stratus and
some fog as well.

Winds will be gusty and out of the east to start, with sustained
speeds near 15kt and gusts 20-25kt. The winds become more SE and
then S after the warm front passage. Winds speeds and gusts will
also decrease also this afternoon into tonight. Winds become
light and variable tonight.

There will be a se-s low level jet of 40-45 kt at 2kft this morning
into early this afternoon.
