Synopsis
High pressure will remain in control through the end of the week
before gradually shifting offshore through the weekend. A dry
cold front will approach from the north on Thursday and move
through the local area on Friday. Another cold front will then
slowly approach and pass through during the middle of next week.

Near term until 6 am Thursday morning
Forecast is generally on track. Hourly temps dewpoints were a
few degrees cooler lower than forecast so have adjusted these
based on latest obs trends.

Otherwise, seasonable weather continues as high pressure
remains across the area. Although clear skies and light winds
will create favorable radiational cooling conditions tonight,
subtle return flow has allowed dewpoints to increase into the
mid 40s to lower 50s. As such, low temperatures tonight will be
closer to normal climatological values rather than the below
normal we have experienced the past few nights.

Short term 6 am Thursday morning through Thursday night
Southwesterly flow will strengthen into Thursday ahead of a weak
cold front. Temperatures will be 5 to 10 degrees above normal
in warm advection, particularly to the west of nyc where marine
influence will be minimal. Have trended a few degrees above
guidance in these areas, primarily for northern nj. A few gusts
will be possible by evening ahead of the front and with its
passage late. The mixing associated with the front will keep
temperatures above normal into the overnight. Given the
antecedent dry air mass, no precipitation is expected with the
frontal passage.

Long term Friday through Wednesday
Large ridge remains in place Friday and Saturday, ahead of
downstream trough that will makes its way east, deepening as it does
so.

The global models prog a southern stream cutoff low over the
southeast states Monday, and this shortwave energy quickly moves
northeast Tuesday ahead of the main longwave trough that remains to
the west, slowing down as it deepens Tuesday and Wednesday.

Surface high pressure builds behind a weak front during the Friday
through Sunday period.

By Monday, a wave of low pressure likely develops over the southeast
states along a cold front. The front will make slow eastward
progress, approaching Tuesday and passing Tuesday night as low
pressure rides along it. Still, there is much uncertainty though on
all these features and forecast details this far out as the front
could move east or stall nearby.

As for sensible weather, dry conditions are expected until Monday,
or Monday night. Increasing chances for showers Monday night
Tuesday can be expected ahead of shortwave trough front. In fact,
increasing moisture sweeps northward as the gulf of mexico is tapped
which could lead to some heavier showers Tuesday or Tuesday night.

These showers could very well linger into Wednesday depending on
speed of front and trough, a conveyor belt of moisture advecting
south to north. Have a feeling the slower solutions will pan out due
to strength of the trough. Either way, showers will be possible as
upper cold pool approaches from the west if the front passes quicker.

Temperatures through the period will remain several degrees above
normal.

Aviation 23z Wednesday through Monday
Vfr through the TAF period with high pressure remaining southeast of
the region through Thursday evening.

Sw winds 10-12 kt will continue for next few hours at city
terminals. Winds will diminish overnight to around 5 kt at city
terminals and light and variable elsewhere. SW flow increases
on Thursday and becomes gusty in the afternoon. Start time of
the gusts could vary a few hours from forecast.
