Synopsis
Mainly dry and comfortable weather is expected for the rest of
the week and into the weekend with temperatures generally a
little below normal levels for late august.

Near term until 6 am Thursday morning
Isolated showers weakening as they head into the western mohawk
valley and southern adirondacks this evening. By shortly after
midnight the showers should dissipate. Mainly clear sky
expected tonight outside of the showers and just some minor
adjustments to the forecast through tonight based on current
observations and trends. Previous afd has a few more details and
is below...

there exists a secondary front wind shift boundary upon which a
line of showers has tracked to the northeastern shore of lake
ontario. High resolution models do not seem to be picking up on
this activity well. Have expanded pops slightly into the western
adirondacks between roughly 21z and 02z as extrapolation of
this line brings it across northern portions of
herkimer hamilton counties. Otherwise, a tranquil evening and
night is expected. Low temperatures tonight will be much lower
than recent nights in the mid-40s to mid-50s. Some shallow fog
is possible in favored river valleys, but due to the overall
dryness of the airmass, as well as some question with respect to
decoupling potential tonight as a modest pressure gradient
remains over the area, have not included fog in the public
forecast.

Short term 6 am Thursday morning through Saturday
For the remainder of the week into Saturday, models are in good
agreement that a mean longwave trough will be in place over the
northeastern us, with a mean longwave ridge over the northern
plains. At the surface, this will promote an expansive region of
high pressure from hudson bay into the mid-mississippi valley
and expanding into the northeastern us. H500 t850 anomalies will
average 1-2 standard deviations below normal during this period,
so temperatures can be expected to come up on the order of 5f
below normal. With a dry airmass in place (pwat values aob
0.75"), precipitation chances will be low throughout the period.

However, a shortwave trough now evident over the southern
canadian prairies will rotate into the northeastern us late
Thursday Thursday night, going from positive to neutral tilt.

Lift from this wave, along with diurnal terrain effects, may
generate a few isolated showers over the southern
adirondacks mohawk valley southern greens. As high pressure
exerts more of an influence Friday and Saturday, have a dry
forecast everywhere. Friday night looks to be the coldest night
of the period, with temps bottoming out mainly in the 40s to
around 50. Can't rule out some 30s in high-elevation valleys.

Last time the temp fell into the 40s at kalb was june 8.

Long term Saturday night through Wednesday
A very tranquil period is expected Saturday night through Wednesday.

The mean upper trough axis is nearby through about Monday, then flat
upper ridging builds into our region Tuesday and Wednesday.

Surface high pressure will build out of canada and the great lakes
into our region through the weekend and beginning of the week before
the flat upper ridging and surface high pressure builds east into
our region toward the middle of the week, allowing for some
southerly low level flow and slow and gradual warm advection.

This stable upper and surface pattern will result in high
temperatures nearly the same each day from Sunday through Wednesday
with just slow warming through the period. Highs are expected to be
in the mid 70s trending to upper 70s through the period in most
areas but mid 60s trending to lower 70s in higher terrain.

Aviation 02z Thursday through Monday
There could be some fog tonight between 06z and 12z, especially
at kgfl and kpsf but there could also be some very light winds
persisting through the night that could prevent fog. Will
include MVFR visibility in fog for now and amend to ifr if
denser fog forms. High pressure will control the weather and
just scattered clouds are expected at the most through Thursday
afternoon.

West winds will diminish to calm or near calm tonight. West
winds will increase to around 6 kt Thursday morning continuing
during the afternoon.

Outlook...

Thursday night through Monday: no operational impact. No sig
wx.

Fire weather
Seasonably cool airmass in place for the remainder of the week
into the weekend, with high temperatures averaging in the mid-
60s to mid-70s. After areas of morning dew shallow fog, rh
values will bottom out in the 45 to 55 percent range Thursday
and Friday. Winds Thursday and Friday will be somewhat lighter
than Wednesday, generally out of the northwest at 5 to 10 mph. A
few isolated showers are possible over the higher terrain
Thursday and Thursday night, otherwise dry.

Hydrology
No hydrologic issues are anticipated over the next five days.

Showers and thunderstorms on Tuesday allowed for some very minor
rises on rivers and streams, mainly smaller creeks. With dry
weather expected to continue, river levels will recede or
remain steady.

Very little to no precipitation is expected through the
weekend, which will allow for river levels to hold steady.

For details on specific area rivers and lakes, including
observed and forecast river stages and lake elevations, please
visit the advanced hydrologic prediction service AHPS graphs
on our website.

Equipment
The kenx radar will likely be down through at least Friday,
september 1st for the bull gear replacement. We are waiting for
a roc maintenance team and parts to arrive to assist local
technicians with the repairs.
