area forecast discussion
national weather service mount holly nj
112 pm edt Fri mar 24 2017

Synopsis
A warm front will lift to our northwest today, then a backdoor
cold front pushes through the area Saturday. This front is
forecast to stall near the southern portions of the area through
Sunday, then return northward as a warm front Sunday night into
Monday as low pressure moves through the great lakes. Another
low pressure if forecast to move out of the midwest and offshore
of the northeast Tuesday into Tuesday night, pulling a cold
front across the east coast. High pressure will try to build
down from the north Thursday.

Near term /until 6 pm this evening/
Precipitation is quickly moving out of the region. Thus, allowed
the winter weather advisory to expire at 1 pm. Also updated pops
to reflect current radar trends.

Temperatures are expected to be near normal. Highs this
afternoon will top off near 60 across md/de, and in the low to
mid 50s across southern nj and SE pa. The poconos and northern
nj will top off in the mid to upper 40s.

Short term /6 pm this evening through 6 am Saturday/
Zonal flow sets up tonight as high pressure remains anchored
over the southeast u.S. Conditions remain dry, but some mid-
level moisture will spread into the region, keeping cloudy skies
in place tonight.

Lows will drop into the low to mid 40s north of i-76, mid to
upper 40s across southern nj and SE pa, and in the low 50s
across md/de.

Long term /Saturday through Thursday/
A backdoor cold front will sink through the area during the day
Saturday as high pressure moves across northern new england and
eastern canada. The front is then expected to stall just to our
south through Sunday. As the front moves across the area, then
stalls to our south, several short wave/vorticity impulses will
slide across the area as well. This will lead to a chance of
showers across the area, though it will not rain the entire
time. Temperatures will be several degrees above normal Saturday
before the front moves through, then return closer to normal
Sunday on the northern side of the boundary. We will have to
keep an eye on the temperatures across the far north Saturday
night into Sunday. The NAM is hinting at the possibility for
temperatures to drop close to freezing, which could lead to a
period of freezing rain. For now, the forecast keeps all areas
above freezing.

The frontal boundary is then forecast to lift back northward as
a warm front overnight Sunday into Monday as an area of low
pressure moves through the great lakes region. Another couple
of short wave/vorticity impulses are forecast to move across the
area as the warm front lifts northward, and will enhance
precipitation potential across the area. Sunday night into early
Monday morning has the greatest chance of seeing more
widespread precipitation potential.

Another low pressure is then forecast to move out of the
midwest then offshore of the northeast Tuesday into Tuesday
night, pulling a cold front across the east coast. This will
keep unsettled weather across the area through Tuesday night as
several short waves/vorticity impulses slide across the area.

Behind the cold front, drier weather is then expected to return
for Wednesday into Thursday.

Temperatures are currently forecast to be a few degrees above
normal for the majority of next week.

Aviation /17z Friday through Tuesday/
The following discussion is for kphl, kpne, kttn, kabe, krdg,
kilg, kmiv, kacy and surrounding areas.

Vfr conditions are expected through most of the TAF period.

There is a very small chance of MVFR ceilings late tonight or
early Saturday morning. Ceilings will decrease after 18z to MVFR
with possible localized ifr conditions.

Southwesterly winds will gust near 20kt through the day time
hours, but should drop below 10 kt by 00z.

Low level wind shear is possible between 02 and 10z with a low
level jet of 35 kt around 2000 ft agl.

Outlook...

Saturday night-Tuesday... MVFR or ifr conditions with a chance
of rain possible through the period.

Marine
Sw winds increase to 15-20 kt with gusts up to 25 kt across
northern nj waters this afternoon and into this evening. Sca
remains in effect. Will hoist a SCA for de bay and de ocean
waters as confidence in a period of 25 kt gusts for this
afternoon and early evening is increasing.

Conditions gradually subside to sub-sca conditions tonight.

Outlook...

Saturday-Saturday night... Conditions expected to fall below
advisory levels.

Sunday-Sunday night... Small craft advisory levels possible.

Monday-Tuesday... Winds may be below advisory levels, but seas
could remain elevated leading to small craft advisory levels.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data.

For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
