Synopsis
High pressure at the surface and aloft will remain parked over
the region through the next several days, providing dry
conditions and continued above normal temperatures. Temperatures
could reach record high levels today through Tuesday.

Near term until 6 pm this evening
Despite some patchy fog this morning, temperatures are forecast
to hit record levels this afternoon. This is due to high
pressure both at the surface and aloft working its way over the
region. The latest GEFS 925mb temperatures are 1 to 3 standard
deviations above normal. Additionally, temperatures will start
out 10 degrees higher than yesterday morning (when highs reached
the mid 80s), making reaching the low 90s very possible this
afternoon for many locations.

Short term 6 pm this evening through Tuesday night
Hot and humid weather will continue through the period as the
core of the abnormally warm temperatures and ridging becomes
centered overhead. A weak backdoor wind shift boundary could
turn the surface winds to east and southeast Monday night and
Tuesday but winds still expected to be very light.

Low level moisture will increase gradually as well and the
combination of temperatures and dew points will make it feel
like summer. Dew points will rise solidly into the 60s and with
highs well into the 80s low 90s, heat indices could peak in the
mid 90s in some areas. The core of the heat looks like it will
get squeezed to the north and west of albany but this depends on
how the backdoor boundary moves and if the low level ridging
gets split by the boundary.

Sunny skies are expected today and Monday with record highs
possible both days. These records are highlighted in the climate
section below. Clouds and low level moisture will start
increasing on Tuesday ahead of hurricane maria approaching the
carolina coast and the upper ridge starting to weaken. Depending
on the cloud cover, some locations could eek out 90 degrees
again on Tuesday. By Tuesday night, shower chances return from
southeast to northwest.

Long term Wednesday through Saturday
The extended forecast period opens with the mid and upper level
ridge over the northeast weakening, as the flow aloft becomes
flatter. Hurricane maria is likely to be located somewhere near or
east of the outer banks of nc midweek with some differences in the
location and timing of maria between the gfs ECMWF canadian ggem.

Please refer to the national hurricane center for official forecasts
on maria. A cold front will be approaching from the great lakes
region and the midwest mid-week. Wednesday looks like the last
above normal temperature day with h850 temps in the +16c to +17c
range. Sfc dewpoints will also continue in the upper 50s to mid 60s.

Scattered showers and isolated thunderstorms are possible ahead of
the front. The instability does not look large, as sbcapes are in
the 250-750 j kg range for portions of the region. Some enhanced
shower activity may be with an outer low-level convergent band well
north of maria. Scattered showers will likely linger into the
evening. MAX temps will be about 15 degrees above normal still with
lower to mid 80s in the lower elevations, and 70s to around 80f over
the higher terrain. Lows will be in the 50s north and west of the
capital district, and lower to potentially mid 60s from the capital
district south and east into the mid-hudson valley, southern
taconics, and NW ct.

Thu-thu night... The sfc cold front will be east of the region in the
morning, but the better push of low to mid level cold advection will
be moving across the region during the late morning and into the
afternoon. Hurricane maria takes a hard right and gets picked up by
a broad and somewhat amplifying upper level trough. H850 temps fall
to +4c to +8c from the capital region north and west by the early
evening. There will be a decrease of showers during the day with
only some isolated instability or upslope isolated showers over the
western new england higher terrain, and the western adirondacks
during the afternoon. It will become breezy and cooler with highs
trending downward and closer to normal late sept readings with
mainly mid 60s to mid 70s with some cooler readings over the
mountains such as the southern dacks, and a few upper 70s are
possible in the mid-hudson valley. Lows fall into the 40s to lower
50s with a few u30s in the southern dacks.

Friday into Saturday... The mid and upper level trough continues to
dig equatorward with another cold front approaching from the west
fri. Most of the day should be dry with just a slight chc of a lake
enhanced shower for the southern adirondacks. Brisk and cool
conditions will usher in temps very close to late sept seasonal
normals. A secondary cold front, and a trough of low pressure will
bring some scattered showers to the area late Fri night into sat.

Some differences between the 00z ec and 00z GFS with the evolution
of the the mid and upper trough, where ec has the low close off over
the lower great lakes region and a wave of low pressure developing
off the mid-atlantic coast, as some rain would spread north for the
2nd half of the weekend. Temps may close sept near normal or a
couple degrees below normal with lows in the upper 30s to upper 40s,
and highs in the 50s to mid 60s.

Aviation 07z Sunday through Thursday
A strong ridge of high pressure at the surface and aloft will
remain in place over the region through today providing hot and
dry conditions.

The winds have gone calm with the skies clear over the eastern
ny and western new england terminals. Radiational fog is
expected to form over the favored climatological sites of
kgfl kpsf. Ifr or lifr conditions are forecasted especially
between 08z-12z. The low-level dewpts continue to rise. At
kalb kpou with a dry boundary later less confident still for ifr
mist fog and have continued withVFR conditions at kalb with
just some shallow fog (mifg) especially between 09z-12z. For
kpou, we did place a narrow window of some patchy MVFR mist in
from 10z-12z. Any patchy mist or fog will burn off by 12z-13z
with strong subsidence with the ridge and plentiful sunshine.

Vfr conditions are expected the rest of the day into the early
evening with a few-sct cirrus around, and perhaps a few diurnal cumulus
at kpsf.

The winds will be calm this morning, then increase from the
north to northwest at 4 to 8 kt by the late morning into the
afternoon. Local topographical effects could allow for more of
an east southeast wind at kgfl at 5 kt or less. The winds will
become calm once again early this evening.

Outlook...

Sunday night through Tuesday night: no operational impact. No
sig wx.

Wednesday: moderate operational impact. Chance of shra... Slight
chc tsra.

Wednesday night: moderate operational impact. Chance of shra.

Thursday: low operational impact. Slight chance of shra.

Fire weather
High pressure at the surface and aloft will remain parked over
the region through the next several days, providing dry
conditions and continued above normal temperatures. Temperatures
could reach record high levels today through Tuesday.

Rh values will be in the 90 to 100 percent range tonight and
Monday night. Rh values will drop to 40 to 60 percent this
afternoon and Monday afternoon.

Light and variable north to northeast winds will persist today,
then trend east and southeast Monday.

Hydrology
No widespread hydrologic issues are expected through the next
week. An extended stretch of fair and warm weather is forecast
well into this coming work week as high pressure dominates. The
next chance for rainfall will be on Wednesday and Thursday with
less than a tenth of an inch of rainfall expected.

observed and forecast river stages and lake elevations, please

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
