Area Forecast Discussion
National Weather Service Albany NY
113 PM EDT Tue Aug 14 2018
.SYNOPSIS...
An upper level low pressure system will slowly move eastward
across the region today into tonight, bringing occasional
showers and scattered thunderstorms. Thunderstorms will be
capable of producing locally heavy rainfall with flash flooding
possible. A cold front will cross the region late Wednesday
bringing another chance of showers and thunderstorms.
&&
.NEAR TERM /THROUGH TONIGHT/...
As of 100 PM, low pressure axis starting to shift south and
eastward. Latest radar showing strongest returns across the
northwestern Adirondacks, Catskills and the Berkshires. Across
the Greater Capital Region and the Lake George Saratoga region
radar is quiet right now as we are in the dry slot. As the
system continues to move eastward, the radar should fill in.
Have updated temps, skies and dewpts based on latest
observational data.
Flash Flood Watch remains in effect for Northern Fulton county,
the Saratoga and Glens Falls region, Capital District, mid
Hudson Valley and Taconics, Mohawk Valley, Schoharie Valley and
eastern Catskills through this evening.
A cut-off low centered over central PA will continue to slowly
track eastward today, with the core moving into south-central NY
by late in the day. Large scale ascent will increase in our
area, as we will be in the left exit region of an upper level
jet streak east of the upper low core. The synoptic scale
forcing combined with continued anomalous deep moisture (PWAT
anomalies around +1 STDEV) and tall/skinny CAPE of 1000-1500
J/Kg, will result in locally heavy rainfall within the taller
convective plumes. Wind field will be fairly unidirectional and
relatively light, so convective cells will be slow-moving. We
have expanded the Flash Flood Watch to include much of eastern
NY except for the Adirondacks. Soil moisture/antecedent
conditions continue to run wet in the watch area, but much drier
in the Adirondacks. The potential for convection with heavy
rain will spread eastward through the afternoon. For western New
England, the main question is if there will be enough
instability to sustain taller convective plumes by later this
afternoon into the evening. So we will hold off on any watches
there for now, but monitor trends closely through the day.
As instability wanes later this evening, intensity/coverage of
convection should decrease. Also, models indicating the upper
low will open up and become more progressive overnight. So will
end the flash flood watch by midnight. Widely scattered showers
will still be possible after midnight as the upper trough moves
across New England, mainly for areas north and east of Albany.
Short wave ridging will start to move in early Wednesday
morning, with drying conditions expected by sunrise. It still be
warm and muggy, with no discernible change in air mass.
&&
.SHORT TERM /WEDNESDAY THROUGH THURSDAY/...
Wednesday should start out dry with short wave ridging over the
area. However, during the afternoon/early evening models are
indicating a disturbance aloft and a surface trough moving
through northern NY. Residual low-level moisture and surface
heating will result in SBCAPE of around 1000-2000 J/Kg with 0-6
km increasing to around 25-30 kt. The magnitude of instability
and shear could result in a few strong to severe storms across
the Adirondacks. Coverage should only be widely scattered
though, and isolated farther south and east. With more sunshine
and better mixing than recent days, it will be become very warm
with high temps well into the 80s for most valley locations.
Convection will diminish Wednesday evening with loss of daytime
heating and the trough moving east of the region. We will
continue to experience warm/muggy night with lows again expected
to be mainly in the 60s. It will continue to be very warm and
humid on Thursday, with short wave ridging through at least the
first half of the day. A disturbance embedded within another
upper level trough approaching from the Great Lakes may trigger
some widely scattered showers and thunderstorms late in the day.
Will mention slight to low chance pops for now, with the higher
probabilities west of the Hudson River valley.
&&
.LONG TERM /THURSDAY NIGHT THROUGH MONDAY/...
The weather turns unsettled once again as a trough and low
pressure approach and move across the region. Friday will have
large scale ascent with height falls across the region as a
couple of short waves move through the trough. Have pops
increasing from west to east Thursday night with likely for
most of the forecast area Friday. The trough is expected linger
into the weekend however guidance is not in agreement for how
long this should occur. Have maintained chance pops across the
area for Saturday with slight chance for Sunday. By Monday
there is some agreement some ridging should build into the
region as its induced ahead of a digging trough with indications
along closed off upper level low should develop to our west
early next week. There is much uncertainty as to where this will
occur but does indicate more unsettled wet weather.
Above normal temperatures still expected for Friday despite
clouds and rain as we start out mild and have a southerly flow.
Seasonable readings expected over the weekend with more above
normal as we head into next week.
&&
.AVIATION /18Z TUESDAY THROUGH SUNDAY/...
Upper level low will gradually move eastward across the region
this afternoon. Ceilings and vsibilities will be VFR this
afternoon. As convection is on the increase this afternoon,
showers and thunderstorms will be possible with heavy downpours
into the early evening hours. MVFR to IFR are expected with any
storms. An improvement to VFR should occur in the evening
however overnight where cloud cover decrease fog and/or stratus
are expected especially where it rains today.
Winds will be light and variable this afternoon and evening. By
Wednesday afternoon, winds will be out of the west around
10kts.

.FIRE WEATHER...
An upper level low pressure system will slowly move eastward
across the region today into tonight, bringing occasional
showers and scattered thunderstorms. Thunderstorms will be
capable of producing locally heavy rainfall with flash flooding
possible. A cold front will cross the region late Wednesday
bringing another chance of showers and thunderstorms.
&&
.HYDROLOGY...
An upper level low pressure system will bring occasional
showers and scattered thunderstorms through this evening. Deep
moisture will accompany the low as it pushes east. Some storms
will be slow-moving and produce locally heavy rainfall. As a
result, the Flash Flood Watch has been expanded to include much
of eastern New York except for the Adirondacks, where antecedent
conditions have been much drier. For the rest of the area, it
has been wet over the past several weeks, with soil moisture
already running anomalously high.
Main stem river flooding is not likely across most of the area,
however the Schoharie basin is running high so additional
rainfall could result in renewed flooding along the Schoharie
Creek at Gilboa Bridge, or new flooding at Prattsville.
Some areas will receive 1 to 2 inches of rain with locally
higher amounts, especially in the Flash Flood Watch area. This
rainfall could occur in three hours or less, thus resulting in a
Flash Flood threat. Conditions are expected to improve
overnight, with showers and storms tapering off.
Widely scattered showers and thunderstorms will be possible
associated with a cold front passage Wednesday afternoon into
Wednesday evening. Then, more unsettled weather is expected
towards the end of the week as another low pressure system
affect the region. Showers and thunderstorms with locally heavy
rainfall will be possible again.
