616 am edt Mon apr 24 2017

Synopsis
Dry weather into tonight as high pressure dominates. However,
chances for rain will be on the increase late tonight into
Tuesday morning as coastal low moves up the east coast. A
widespread rainfall will occur across the area lingering into
Wednesday.

Near term /through tonight/
Today will be another day mild day with sunshine as high pressure
dominates despite a weak boundary which moved southward into
the area yesterday stalls across the region as the flow aloft
parallels it. A subtle difference in dew points denotes the
location of the boundary. High level clouds will be on the increase
from the south especially this afternoon in advance of an approaching
coastal low along the southeastern coast. High temperatures will
be similar to Sunday across most of the forecast area. The difference
will be across the northern most portion of the local area where
cooler temperatures are expected to the north of the stalling
boundary, otherwise readings should be a degree or two warmer;
mid 60s to lower 70s.

Short term /Tuesday through Wednesday night/
Widespread rainfall and much cooler temperatures for Tuesday.

A surface low has developed along the southeast coast in response
to an upper level low moving across the southeastern united
states which is separated from the mean flow. The system will
become vertically stacked by tonight as it begin to move head
northward up the coast. Ridging across our region to the north
of the low will strengthen tonight into Tuesday morning as it
gradually retreats. The air mass in place across the region is
very dry which can see on the 00z upper air soundings from last
night with a precipitable water values of only 0.31 inches here
at albany and 0.26 inches at both upton/brookhaven long island
and chatham ma.

So despite the developing onshore flow off the atlantic it will
take time for the atmosphere to moisten up and for rain to move
in. Have slowed the onset and spread of the rainfall across the
area with it mainly occurring Tuesday morning with clouds on
the increase thickening and lowering tonight. The low will move
northward up the coast as a trough digs across the central conus
through mid week. This will keep the low close to the coast. As
the low approaches and its associated low level jet moves in
and across the region rain will continue through Tuesday night
into Wednesday morning especially east of the hudson river
valley. Conditions should gradually improve on Wednesday. Qpf
amounts are anticipated to range from about a third of an inch
to around an inch across the forecast area from northwest to
southeast through Wednesday.

It will cool Tuesday with highs only in the upper 40s to mid
50s with the rain. Temperatures are expected to rebound to
seasonable levels Wednesday.

Long term /Thursday through Sunday/
Active pacific jet will carve out a deep time-mean longwave trough
over the western conus. Downstream, deamplifying waves emanating
from this trough will battle a building ridge centered across the
southeastern us. Model consensus favors positive upper height
anomalies over the eastern third of the us, so above-normal
temperatures are favored during the long-term period.

The first deamplifying wave will track northeastward across the
western great lakes Thursday and Thursday night. Models have
continued to trend slower/further west with this wave such that it
appears Thursday will be dry and warm, with h85 temps approaching
15c. The front with the upper disturbance's attendant surface low
appears to wash out as it approaches our area, but some weak
convergence and low-amplitude waves in upper southwesterly flow as
the longwave trough edges eastward argues for isolated/scattered
shower/storm coverage Thursday night into Friday.

For the weekend, models try to expand the strong anticyclone
centered over the southeastern us northward, while a deep upper low
sets up over the intermountain west. Moisture return in between
these systems looks to result in a large west-east band of precip
along a warm front. The position of this front looks to be the key
for precipitation chances, as the eastward extend of it will be
nearby, but encountering surface and upper ridging over the
northeast. Some low-amplitude disturbances cresting the ridge could
result in some ascent as well. Moisture will be there, with pwats 1-
1.5 inches. However, with strong upper ridging in place have sided
toward a drier forecast over the weekend, with the relatively better
chance for isolated/scattered showers/storms Sunday.

Aviation /10z Monday through Friday/
Vfr conditions expected to prevail through the forecast period.

High clouds will gradually increase and thicken from the south
through the TAF period as a low pressure system approaches up
the coast. Light rain showers will be possible toward the end of
the TAF period mainly at kpou.

Light and variable winds during the day today. Calm winds
tonight becoming light easterly toward daybreak Tuesday.

Outlook...

Tuesday night: high operational impact. Likely shra... Ra.

Wednesday: moderate operational impact. Chance of shra.

Wednesday night: no operational impact. No sig wx.

Thursday: no operational impact. No sig wx.

Thursday night: moderate operational impact. Chance of shra... Tsra.

Friday: moderate operational impact. Chance of shra... Tsra.

Fire weather
Low relative humidity values this afternoon...

dry weather into tonight as high pressure dominates. Chances for
rain will be on the increase late tonight into Tuesday morning
as coastal low moves up the east coast. A widespread rainfall
will occur across the area lingering into Wednesday.

Minimum relative humidity will be in the 30s this afternoon
with a recovery to 75 to 90 percent tonight. Minimums Tuesday
will be from the mid 60s to mid 70s.

Light northeast to east winds will develop today and continue
tonight. The flow will become more easterly Tuesday with wind
speeds increasing to 10 to 15 mph.

Hydrology
Dry weather into tonight as high pressure dominates. Chances for
rain will be on the increase late tonight into Tuesday morning
as coastal low moves up the east coast. A widespread rainfall
will occur across the area lingering into Wednesday. Qpf
amounts are anticipated to range from about a third of an inch
to around an inch across the forecast area from northwest to
southeast tonight through Wednesday. A brief break in the wet
weather is expected Thursday before cold front approaches and
moves through Thursday night into Friday bringing chances for
showers and thunderstorms to the area.
