Synopsis
Dominant high pressure is briefly shunted southward on Thursday
as a cold front passes to the north. The high then rebuilds
through late week before gradually shifting offshore through the
weekend ahead of an approaching cold front. The front slowly
moves towards the area through mid week.

Near term until 6 am Thursday morning
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 dew points 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 22z Wednesday through Monday
High pressure builds southeast of the region through the taf
period with a high confidence ofVFR continuing for most
terminals. Only exception would be kswf where there is a low
chance of some MVFR patchy fog overnight into daybreak Thursday.

Wind speeds stay around 10 kt or less through tonight with
winds picking up Thursday afternoon to 10kt or just a few kts
higher, gusting to 15-20 kt. Gust timing could vary a few hours
from forecast.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
