Area Forecast Discussion
National Weather Service Mount Holly NJ
339 PM EDT Wed Apr 18 2018

.SYNOPSIS...
A area of low pressure will move across the area tonight into
Thursday, along with its associated occluded, warm, and cold
fronts. This low will drift into the Canadian Maritimes through
Friday, which will keep northwest flow across the area with a
couple of dry surface troughs moving across the east coast. High
pressure will build into the Mid Atlantic and Northeast
Saturday through Sunday, before moving offshore Monday into
Tuesday. A coastal low may move north along the coast and affect
the area during the middle of next week.

&&

.NEAR TERM /UNTIL 6 AM THURSDAY MORNING/...
Surface low pressure will approach the region from the west
tonight, moving into our area late tonight. Cloud cover will
increase quickly tonight as the low moves closer to the area.
Some light rain will fall, in advance of the approaching low but
amounts are expected to remain light, with southern areas
likely remaining dry through daybreak.

Overnight lows will drop into the mid to upper 30s across the
northern zones to mid to upper 40s across the southern zones.

&&

.SHORT TERM /6 AM THURSDAY MORNING THROUGH 6 PM THURSDAY/...
Low pressure will cross the region tomorrow, dragging a cold
front through during the late morning/early afternoon. Some
light rain will fall across the region as the low crosses the
area. Amounts will be fairly light, especially across southern
areas, with only a tenth of an inch or less expected. As
temperatures cool across the higher terrain, a few flurries or
light snow showers may occur as the precipitation starts to come
to an end toward Thursday evening.

Extensive cloud cover across the northern half of the forecast
area will keep much cooler and only into the upper 30s to mid to
upper 40s. Once you get down towards Philadelphia and points
south, skies should see a few breaks. Highs into the upper 50s
to lower 60s are expected.

Even with the sun peeking out, it will feel cooler through the
day as the winds will really start to ramp up by late
morning/early afternoon. Winds will be our of the north to
northwest at around 15 to 25 mph with gusts up to 35 mph
possible.

&&

.LONG TERM /THURSDAY NIGHT THROUGH WEDNESDAY/...
A quiet start to the extended forecast for the end of the week,
through this weekend, into early next week. A return of
unsettled weather is possible by the middle to end of next week.

On Thursday night, the low pressure that affects the area
during the day will continue to move northward into the Canadian
Maritimes. Most of any precipitation associated with the low
will move to our north with the low pressure. However, there
could continue to be some snow showers across the higher
elevations, especially during the evening hours as the low-mid
level lapse rates may be high enough to interact with some left
over moisture and the passing short wave. These showers will
dissipate through the night into Friday morning as the moisture
dissipates across the area.

On Friday, the low will remain across the Canadian Maritimes,
while surface trough will likely cross the area. The trough will
be dry, and only present a shift in wind direction and possibly
some cloud cover, as it will likely not having much of an
airmass change. Winds during the day will be generally out of
the northwest, and gust 25- 30 mph, occasionally up to 35 mph at
times. Dry and breezy conditions will continue into Friday
night as well.

On Saturday, dry conditions will continue as another dry
surface trough will move across the area, before high pressure
builds into the area overnight. Winds will gust around 20 mph at
times, but it will not be as windy as Friday.

High pressure builds across the Mid Atlantic and northeast
Sunday, before moving offshore my Monday. Dry conditions will
continue for Sunday and Monday.

As we move into Tuesday and Wednesday of next week, a coastal
low is forecast to lift northward along the east coast. There is
timing differences between the GFS, ECMWF, and Canadian. With
the timing differences, there is the potential for rainfall
starting as early as Tuesday, with the most likely period
looking to be Wednesday Wednesday night. Temperatures across the
area are forecast to be above freezing, so the precipitation
would be all rain.

&&

.AVIATION /20Z WEDNESDAY THROUGH MONDAY/...
