Synopsis
Low pressure will deepen over the mid-atlantic today, track through
the tri-state region tonight and into the maritimes on Friday. A
broad area of high pressures builds in for the first half of the
weekend, then a slow moving frontal system will bring the potential
for showers from Sunday into Tuesday.

Near term through Friday
Overall rainfall this morning not too impressive with the local
area split between two heavier batches of rain, one off to the
nw and one offshore. Rain intensity is expected to remain on the
light side for the remainder of the morning with just a few
pockets of moderate rain. Much of this rain is due to isentropic
lift warm advection. No thunder is expected with this activity.

Middle level drying from the south will serve to cut off
widespread rain this afternoon. Have adjusted pops and wx grids
to account for this trend, and included mention of a chance of
light rain or drizzle as the lowest 5,000 feet remain saturated.

Areas of fog are also possible this afternoon.

Easterly winds will be highest this morning with gusts as high
as 25-30 mph, strongest near the coast. Winds will gradually
weaken this afternoon as the pressure gradient slackens.

Attention then turns to the h5 low, which moves over tonight.

Initially middle levels look to dry to support anything more
than light rain or drizzle, but then significant dpva and lapse
rates from h85 to h4 range avg around 6.5c km. The models all
produce convective pcpn. As a result, showers and embedded
thunderstorms are expected overnight.

The upper low reaches the gulf of me on fri. This will allow
for decreasing coverage and intensity of showers through the
day. The downslope flow could allow for clearing, especially
along the coast, by the end of the day.

Temps will be below normal today, then will nudge closer on fri
as the rain ends. A blend of the guidance and raw model data
was used.

Short term Friday night through Sunday night
Weak ridging builds in Fri ngt and Sat which will attempt to
produce fair weather. There is a suggestion of shrtwv energy
swinging thru on sat. If this materializes, isold-sct shwrs will
be possible. A rainy day however is not expected attm. A broad
upr lvl low then drops into the midwest, producing SW flow aloft
across the fcst area sun. This will produce an increasing
chance for shwrs, particularly Sun aftn thru Sun ngt.

Temps will remain close to or blw normal thru the period. The
superblend was used.

Long term Monday through Wednesday
The upr low over the midwest will drive a slow moving frontal
sys thru the region for the beginning of the week. There is
some uncertainty wrt the timing, with the ECMWF slightly faster
than the gfs. Chance pops remain in the fcst.

Weak ridging builds in Tuesday, followed by more shortwaves
rotating around the S canada closed low, which has slid a bit
farther E into hudson bay NW ontario), Tuesday night and
Wednesday - with maybe some more isolated- scattered showers.

Temperatures should be within a few degrees of either side of
normal Sunday-Monday night, then run above normal Tuesday-
Wednesday.

Aviation 14z Thursday through Monday
An area of low pressure will move across the region through the taf
period.

Ifr lifr conds developing this morning in band of light to
moderate rain... And expected to continue into this evening.

Steady rain moves north between 18-20z... With areas of
drizzle light rain in its wake this afternoon. Potential for
lifr visibilities this evening in fog.

Moderate potential for an area of showers and thunderstorms to
move through the region between 02z and 08z. Heavy downpours
are the main threat.

Easterly winds 10-20kt with gusts to 25kt this
morning... Weakening late this afternoon into tonight. Northwest
flow develops Friday morning.

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