Synopsis
A weak frontal passage will occur tonight. High pressure will
dominate from Friday night through Monday. A slow moving frontal
system will then move across during the middle of next week.

Near term through tonight
The patchy fog has dissipated across the region and temperatures
were updated to reflect latest conditions. Otherwise, the
forecast remains on track this morning.

A upper level system over northern ontario will track across
hudson bay today and into northern quebec tonight. This will
drag a boundary through the forecast area late tonight. It is
difficult to call it a cold front because temperatures behind it
on Friday will be virtually the same, but the temperature
structure aloft does indicate that it is indeed a cold front.

Regardless, there is very little moisture to work with so the
frontal passage will be dry.

Winds ahead of the front today will ramp up out of the
southwest. A solid breeze can be expected along the south coasts
by late afternoon, particularly across eastern long island.

Temperatures will remain way above normal again with most spots
at least 70 for highs. Slightly milder temperatures are likely
tonight as winds likely stay up, at least a little, in most
areas. A blend of guidance was used.

Short term Friday
Northwest winds and continued dry. 850 flow in the 35-40kt
range, and with subsidence and a dry airmass, there is a good
chance mixing over preforms the model data. Because of this,
winds were bumped up significantly from the model blend. The
deep mixing flow is also the reason temperatures will be near 70
or above once again. Temperatures were raised above guidance,
but if mixing to 850 is realized, 80 degrees highs will be
realized.

Long term Friday night through Wednesday
Ridging at the sfc and aloft will dominate into Monday ahead of an
upper trough in the western states. As this trough reaches the
plains states, its southern extension will likely cut off over the
south and tap into gulf moisture before phasing with another trough
digging into the northern plains. Wx should be dry and unseasonably
warm until at least Monday, with high temps in the 70s, and possibly
nearing 80 in NE nj on sat.

Nwp guidance continues to trend toward a later timing of the
approaching frontal system for mid next week. There could be some
sct showers and or patchy of light rain drizzle via low level
warm moisture advection well ahead of the approaching front as early
as Mon night-tue. More significant rainfall with the front now looks
to hold off until at least Tue night and possibly until wed, and the
slow moving front, with attendant warm moist conveyor belt, low
level jet, and multiple tropical connections, one out of the gulf of
mexico and another developing out of the subtropical western
atlantic, could become a heavy rain producer during this time.

Aviation 13z Thursday through Monday
High pressure across the region weakens as a weak cold front
approaches from the northwest today. The front begins to cross the
area tonight into early Friday as high pressure returns.

Winds become SW at less than 10kt at all terminals by mid morning.

By early afternoon winds back to the ssw and increase to around 10kt
with gusts up to around 20kt at all but kisp, where infrequent gusts
up to around 20kt are possible. Wind gusts should abate during the
evening, with winds veering to the sw-wsw.

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