Synopsis
An upper level disturbance will bring an isolated shower or
thunderstorm mainly north of the capital region today, as high
pressure will be ridging in from the mid atlantic region with mainly
fair and dry weather. Clouds will increase tonight, as a warm front
will approach from the ohio valley and great lakes region. The warm
front will bring showers and a chance of thunderstorm back in the
region Thursday into Thursday night. A humid and unsettled air mass
will keep the threat of showers and thunderstorms going Friday into
weekend.

Near term until 6 pm this evening
As of 1025 am edt, some cumulus clouds are developing across
the region, with the greatest development across higher
elevations, and also areas north of i-90. Temperatures have
risen into the mid upper 60s within most valley areas, with
upper 50s to lower 60s across higher terrain areas.

The main upper level trough axis is east of the region, per
latest WV satellite imagery. However, an impressive mid level
cold pool will still be across the forecast area in the late
morning into the early afternoon with h500 temps of -20c to
-22c.

A weak mid-level disturbance in the NW flow on the back
side of the upper trough axis may focus isolated
showers thunderstorms north and east of the capital region
today. The sbcapes mucapes are mainly less than 500 j kg on the
nam gfs, and also based on 12z kaly kbuf soundings, but mid-
level lapse rates remain steep at around 7c km. We did keep the
isolated threat in for the western mohawk valley northern
berkshires too for the instability showers isolated
thunderstorms. Still can not completely rule out isolated small
hail gusty winds with any taller convective elements, but
overall coverage should remain less than recent days.

Max temps today will still run below normal by about 5 degrees.

H850 temps will still be about 1 to 2 standard deviations below
normal based on the 00z gefs. Decent mixing coupled with west
to northwest winds of 10 to 15 mph and some gusts 20-25 mph
will allow highs to reach the mid and upper 70s in many of the
valley areas, and across the hills, with 60s to lower 70s over
the mountains. Humidity levels will be very comfortable for late
june with sfc dewpts in the 40s to lower 50s.

Short term 6 pm this evening through Friday night
Tonight... High pressure moves off the mid atlantic coast. Low
pressure will be approaching from the upper midwest and the
western great lakes region. The mid level flow becomes flatter,
as a sfc warm front begins to lift north northeast from the oh
valley and the lower great lakes region. Temps will cool off
early with clear mostly clear conditions and light calm winds,
but mid and high clouds will quickly increase from the
south southwest after midnight. A few showers may graze the
western adirondacks towards sunrise with the leading edge of the
warm advection pcpn, otherwise it will stay dry most of the
night-time period with lows in the 50s with a few upper 40s
across the southern adirondacks eastern catskills.

Thu-thu night... The mid-level flow becomes zonal, as a warm
front will be lifting north across most of the forecast area
during this time frame. Humidity levels will be on the increase
with sfc dewpts rising into the upper 50s to lower 60s late in
the day. The latest nam GFS can ggem ECMWF are converging with
the strongest synoptic forcing due to the isentropic lift warm
advection will be north of the mohawk river valley capital
region during the day. The locations with the most persistent
showers and a slight chc of thunderstorms would be the southern
adirondacks lake george region southern vt. Further south only a
slight to low chc of showers was kept in the capital
region berkshires northern catskills and the mohawk valley. It
may stay dry the better part of the day further south. Several
disturbances will be moving along the warm front with the most
pronounced sfc wave moving east of georgian bay 00z fri.

The better chance of showers and thunderstorms with some
elevated instability and a W SW low-level jet of 35-40 kts will
be Thu night in the warm sector. The model guidance varies with
the potential placement of showers thunderstorms, but a short-
wave and a sfc trough in the flat mid-level flow may kick off a
few rounds of showers and thunderstorms. The showalter
stability indices lower to 0 to -3c with mucapes of 200-800
j kg on the nam. The higher values are north and west of the
capital region. Pwats surge back to 1.25-1.75" in the sticky air
mass. Some locally heavy rainfall is possible Thu night
especially from the mohawk valley north and east. SPC continues
a marginal risk for a small portion of the forecast area
including the mohawk valley, southern adirondacks and the lake
george corridor. This may be due to the potential clusters of
convection or an MCS late Thu into Thu night, if they
materialize.

Highs will be in the upper 60s to mid 70s from the mohawk
valley north and east, with upper 70s to lower and even a few
mid 80s from the capital region south and east. Lows Thu night
will be in the 60s.

Fri-fri night... The forecast area gets into a much more humid
and unstable air mass to close the week. H850 temps rise to the
+16c to almost +18c range on the gfs. Pwats from the latest gefs
increase to 1 to 2 standard deviations above normal. In the
zonal flow aloft a sfc trough or diffuse boundary may focus some
afternoon strong thunderstorms, as sbcapes increase to
1000-2000 j kg. The 0-6 km bulk or deep layer shear is only
25-30 kts, so some multi-cells or multi-cell lines may form.

Chance and likely pops were placed in the grids for Fri with
this potential boundary focusing convection. The showers and
thunderstorms will persist into the night time period. Highs
will be in the mid 70s to lower 80s over the mountains. Mid and
upper 80s will be common across many of the lower elevations and
hill towns. Warm and muggy lows are expected Friday night with
widespread 60s.

Long term Saturday through Tuesday
The period starts out on Saturday with a very warm and humid air
mass entrenched across our region. A surface cyclone is forecast to
track eastward through eastern ontario, with gfs ECMWF both
indicating a noticeably slower trend compared to yesterday's model
runs. Plenty of moisture will be in place, with GEFS continuing to
forecast anomalously high pwats of +1 to +2 stdev. Still expecting a
pre-frontal trough to trigger convection as early as late morning or
early afternoon, especially from the capital district westward.

Sbcape could reach 1500-2500 j kg, especially given sufficient
heating during the early part of the day. Deep layer shear looks to
be relatively weak, so will have to watch for pulse storms with
potential wet downbursts. Also locally heavy rainfall will be likely
with thunderstorms given the abundant deep moisture that will be in
place. Temperatures may reach the mid to upper 80s in valleys, which
combined with dewpoints near 70 will result in heat indices in the
lower to mid 90s.

The likelihood for showers and thunderstorms will continue into
Saturday night, as the surface cyclone moves into NW quebec, while
the system's cold front approaches from central ny. Thunderstorms
could linger through the evening, before instability starts to wane.

There will be continued chances for showers and thunderstorms on
Sunday, as the aforementioned cold front pushes eastward across the
region. Most of the activity should be during the morning afternoon
hours, as guidance indicating the front will be east of the area by
evening. Humidity levels will start to lower behind the cold front,
with temperatures remaining slightly above normal.

Monday looks to feature mostly dry conditions, although an isolated
shower or thunderstorm cannot be ruled out, as a potential weak
short wave trough moves across the area in the weakly cyclonic flow
regime. High pressure then is expected to build in next Monday night
into the 4th of july with seasonable temperatures and comfortable
humidity levels. A frontal boundary may start to creep towards the
region towards the evening on the 4th of july, so will mention
slight chance pops at this time.

Aviation 14z Wednesday through Sunday
Vfr conditions expected today with just few-sct cumulus and
high level cirrus clouds around today. An isolated shower will
be possible near kgfl, but chances too remote to include in the
taf at this time. Mid level clouds will increase late tonight
ahead of a warm front approaching from the great lakes region.

Winds today will be westerly increasing to around 8-12 kt by
late this morning. Some gusts near 20 kt will occur at
kalb kpsf, especially this afternoon.

Outlook...

Thursday night: high operational impact. Likely shra... Tsra.

Friday: high operational impact. Likely shra... Tsra.

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

Saturday: high operational impact. Definite shra... Tsra.

Saturday night: high operational impact. Likely shra... Tsra.

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

Sunday night: no operational impact. No sig wx.

Monday: low operational impact. Slight chance of shra.

Fire weather
An upper level disturbance will bring an isolated shower or
thunderstorm mainly north of the capital region today, as high
pressure will be ridging in from the mid atlantic region with mainly
fair and dry weather. A warm front will approach from the ohio
valley and great lakes region tonight. The warm front will
bring showers and a chance of thunderstorm back in the region
Thursday into Thursday night. A humid and unsettled air mass
will keep the threat of showers and thunderstorms going Friday
into weekend.

The rh values will lower to 30 to 50 percent this afternoon, and
then recover to 75 to 100 percent tonight. The rh values will
lower to 35 to 60 percent Thursday afternoon.

The winds will increase from the west to northwest at 10 to 15
mph with some gusts to 20-25 mph today. The winds will be come
light to calm tonight, and then increase from the south to
southeast at 5 to 15 mph on Thursday.

Hydrology
No widespread hydrological problems are anticipated over the
next several days on the main stem rivers.

A brief period of mainly dry weather is expected today into
tonight with ridging briefly building in from the south.

Isolated showers or thunderstorms may produce a tenth of an inch
of rain or so over the southern adirondacks, lake george
region, and southern vermont today.

An active weather pattern sets up Thursday into the weekend
with showers and thunderstorms possible with increasing humidity
levels each day. Rainfall amounts will vary based on where any
convection occurs. The most widespread potential rainfall is
expected Thursday and Saturday. Rainfall amounts Thursday into
Thursday night may range from a quarter of an inch to an inch
with some locally higher amounts in thunderstorms. The higher
totals right now may be across the northern basins of the hsa.

Numerous showers and scattered thunderstorms are possible on
Friday with basin average rainfall of a quarter of an inch to a
half an inch with locally higher amounts. A more widespread
rainfall in terms of shower and thunderstorm coverage is
expected on Saturday. The heavy rainfall may cause some poor
drainage flooding and ponding of water in low lying areas
heading into the weekend.

and forecast river stages and lake elevations, please visit the
