Area Forecast Discussion
National Weather Service Albany NY
359 PM EDT Tue Jun 13 2017

.SYNOPSIS...
A warm and muggy air mass will be replaced as a cold front will
cross the region. There will be a chance for passing showers
and thunderstorms with some severe. Behind the cold front,
cooler and less humid air will move into the region for the mid
week period. Another frontal system will approach late Thursday
night and into the weekend, with the chance for more showers and
thunderstorms.

&&

.NEAR TERM /THROUGH WEDNESDAY/...
Instability in excess of 2KJ/kg resides from Albany south with
highest instability noted across mid Hudson Valley. Severe
storms have been occurring in this area of maximized
instability this afternoon with wind the culprit due to likely
wet microbursts. The HRRR shows most convection over by 22-23Z.

Drier air was filtering into the region with dew points dropping
into the 50s across northern and western New York. This trend
will continue into tonight.

Drier and more seasonable temperatures are expected through
Wednesday as the nose of the 1026MB surface high near James Bay
spreads its influence southward. Mean PWATs fall back to between
one half to three quarters of an inch as surface dewpoints fall
back further into the 40s.

&&

.SHORT TERM /WEDNESDAY NIGHT THROUGH SATURDAY/...
Surface high pressure drifts east Wednesday night and Thursday
as mid/upper level short-wave ridging works across the area. Dry
weather continues with temperatures running slightly below
normal.

Subtle short-wave troughs sliding along the generally zonal
flow will bring a chance of showers for Thursday night into
Friday. Instability remains muted for Thursday night and Friday,
so will call just SHRA with no mention of thunder. Temperatures
remain on the cool side Friday.

Nearly zonal flow gives way to upper level ridging Friday night
and Saturday. Still maintain a low chance of showers and
thunderstorms for Saturday. Temperatures will rise to near
normal levels with dew points rising.

&&

.LONG TERM /SATURDAY NIGHT THROUGH MONDAY/...
This will be a wet period of high humidities...with showers and
thunderstorms each day through the weekend.  A backdoor cold front
to our west, harboring marine air over our forecast area, will help
to limit the amount of instability initially, but will also help to
keep sunshine to a minimum.  This feature begins to break down over
the weekend, and a cold front will slide through from the northwest
Monday night that will finally trigger a drying trend.

Temperatures will grow cooler each day, with high temperatures
from the mid 70s to mid 80s on Sunday, the mid 60s to lower 80s on
Tuesday.  Tuesday will be noticeably drier.  Saturday and Sunday
night lows will be mostly in the 60s...with lows Monday night from
the mid 50s to lower 60s.

&&

.AVIATION /19Z TUESDAY THROUGH SUNDAY/...
Pre-frontal boundary was sliding south of I90 where some
scattered convection was developing. Due to the scattered nature
of this activity, we will place a VCTS into KALB-KPSF-KPOU at
this time. Otherwise, mainly VFR conditions expected through the
TAF forecast cycle ending 18Z/WED.

Winds will become northwesterly to northerly tonight and
continue into Wednesday with sustained magnitudes 10kts or less
with some higher gusts from time to time just below 20kts.

Outlook...

Wednesday Night: No Operational Impact. NO SIG WX.
Thursday: No Operational Impact. NO SIG WX.
Thursday Night: Moderate Operational Impact. Chance of SHRA.
Friday: High Operational Impact. Likely SHRA.
Friday Night: Moderate Operational Impact. Chance of SHRA.
Saturday: Moderate Operational Impact. Chance of SHRA...TSRA.
Saturday Night: Moderate Operational Impact. Chance of SHRA...TSRA.
Sunday: Moderate Operational Impact. Chance of SHRA...TSRA.

&&

.FIRE WEATHER...
Scattered showers and thunderstorms through this evening will
end as a cold front pushes south of the Albany Fire Weather
Zone.

RH values tonight will range from 75 to 100% tonight,
decreasing to 30 to 40% Wednesday, then rising to 85 to 100%
Wednesday night.

Winds will be northwest to north at 5 to 10 mph.

The next chance for widespread rain showers will be Friday into
Saturday.

&&

.HYDROLOGY...
No widespread hydrologic issues are anticipated over the next
several days.

Recent dry weather has allowed elevated river levels to return
closer to normal flows. A cold front will push south of the
Albany HSA this evening. Scattered showers and thunderstorms
will accompany the front. Best precipitation coverage will be
along southern counties of Ulster, Dutchess, and Litchfield.
These showers will not have any impact on main stem rivers and
streams, but brief heavy downpours will be possible within any
thunderstorm. Although flash flooding is not anticipated, poor
drainage and urban areas could briefly see locally high water
during any thunderstorm.

Dry weather will then return once again for Wednesday into
Thursday. The next chance for showers and thunderstorms will be
Friday into the weekend with another frontal system moving
through the area.

observed and forecast river stages and lake elevations, please
