area forecast discussion
national weather service mount holly nj
332 am edt Sat may 25 2019

Synopsis
High pressure will shift offshore today with a warm front lifting
north across the area tonight. A weak cold front will then move
through the area late Sunday, with weak high pressure then returning
to start the week. Multiple areas of low pressure will track north
of the area across the great lakes through the middle of the week
with generally warm and unsettled weather prevailing.

Near term today
High pressure will be across the area today before heading out
to sea. Clouds will overspread the area by afternoon as a warm
front approaches from the west. Tstms across mi early this
morning will send some debris cloudiness in from the NW by dawn
and this will spread se. A dry day is expected, by-in-large, but
a few sct showers are possible across the far NW during the
late afternoon early evening.

High temperatures will probably be a bit cooler than Friday, owing
to the extra cloudiness expected. The 00z NAM was quite cool with
its maxt for today, be didn't go quite that low, but instead blended
it in with the previous fcst. Highs will be mostly in the low mid
70s with some upper 60s far nw. Humidity levels will still be
comfortable for the most part, but will begin to creep up across the
sw areas later today.

Short term tonight
The warm front will cross the area tonight and it will
bring some sct showers and perhaps a TSTM to most areas. We have keep
pops in the NW areas in the chc range, but a bit lower than the
previous fcst. Other area will continue with slgt chc or low chc
pops for the overnight. Lows will be mild across DELMARVA and SRN nj
with readings only dropping into the 60s. Further N ne, lows will be
in the upper 50s to low 60s.

Long term Sunday through Friday
Overview: most of the extended will be characterized by a
similar pattern to the past week with troughing over the
western us and ridging over the southeast. The surface low
track generally will remain north of the area over the great
lakes and southern canada. Similar to this week, upstream
convective systems will be significant players in sensible
weather locally. However, global guidance typically does not
handle these systems and their downstream impacts well
introducing an extra measure of uncertainty into the forecast.

Generally we will remain warm in this pattern with a chance of
storms everyday except Monday.

The pattern potentially shifts towards the end of the week as a
more significant shortwave lifts out of the western us and is
absorbed into the longwave trough setting up over hudson bay.

This amplifying northern trough may flatten the ridge enough
locally to allow for more substantial (at least from a dynamic
standpoint) systems to move through in the following week
(although uncertainty is naturally high given the time frame).

Dailies:
Sunday... A very warm day and humid day is likely as we will be
in the warm sector on Sunday. High temperatures will likely
approach 90 in the southern half of the area with dewpoints
rising to the mid to upper 60s. These factors will create an
unstable airmass with MLCAPE values over 1000 j kg (possibly
approaching 2000 j kg). Our storm chances will largely depend
upon the track evolution of an upstream MCS and convectively
enhanced shortwave, however a lack of directional shear (mostly
zonal flow at all levels) will likely limit severe chances
despite the fairly substantial instability. That being said
can't rule out some stronger storms particularly in western
portions of the area
Monday... Memorial day looks fairly quiet as we dry out behind
Sunday pm's cold front (maybe a slight chance of lingering
storms in delmarva). Highs generally in the low 80s with a good
amount of sun.

Tuesday... Moisture instability return as another weak surface
low tracks north of us and the warm front crosses the area.

Convection will be possible although once again difficult to
pinpoint due to upstream effects. Maxes similar to Monday but
more uncertain due to cloud cover and onshore flow potential.

Wednesday... Unfortunately guidance starts to diverge here, with
the GFS cmc indicating a very warm day (highs in the 90s over
the southern half of the area) although mostly dry. The 00z ec
on the other hand tracks Tuesday's low much closer to the area
and pushes a cold front through by early Wednesday, and then
reignites convection later in the day. Leaned more towards the
gfs cmc solutions this package as they seems more logical given
the synoptic pattern.

Thursday Friday... A stronger wave frontal system may approach
the area in this time frame, but details are lacking. Thursday
still looks quite warm (possibly warmer than Wed if the ec
solution verifies).

Aviation 07z Saturday through Wednesday
The following discussion is for kphl, kpne, kttn, kabe, krdg,
kilg, kmiv, kacy and surrounding areas.

Today... High pressure across the area this morning moves
offshore late. A warm front approaches from the w. Clouds will
increase over the area today, but conditions will remainVFR.

Mostly hi mid clouds early then some low clouds W NW late. Winds
will be mostly light this morning then veer to E SE at 5 to 10
knots. Winds may further go mostly S by dusk.

Tonight... The warm front crosses the region tonight. Guidance
varies greatly with regards to CIGS with the NAM being pessimistic
and the mav not so bad. We have opted to go the mav route presently,
but if showers become more of an issue overnight, I could see more
lower CIGS like the NAM has. The 12z tafs may try to fine tune the
details better. Winds S early then SW behind the front. Sct showers
psbl.

Outlook...

Sunday... MostlyVFR. Scattered showers and thunderstorms
possible Sunday pm, which may briefly lower conditions at select
terminals. Winds veering from westerly to northerly by Sunday
night Monday morning
Monday... VFR conditions expected, winds light and variable.

Tuesday Wednesday... VFR conditions prevailing, however
scattered showers and thunderstorms will be possible both days.

Marine
Today... Fair weather expected with sub-sca conditions. Winds will
become SE this afternoon and wind speeds will increase with some
gusts around 20 knots across delaware bay.

Tonight... A sct TSTM is possible, but mostly fair weather overnight.

Winds will become S and increase to near SCA conditions, we will
hold the gusts below SCA criteria for now, with the warmer air
across the colder waters. A few gusts to 25 knots are still
possible however.

Outlook...

sub-sca conditions expected through at least Wednesday.

There will be some chance of thunderstorms every day except
Monday however.
