AREA FORECAST DISCUSSION
National Weather Service Albany NY
129 AM EDT Sun Jun 16 2024

.SYNOPSIS...
Fathers Day will feature partly to mostly sunny skies and
pleasant weather with high pressure in control. Hot and humid
weather arrives Monday and continues through most of the week.

&&

.NEAR TERM /UNTIL 6 AM THIS MORNING/...
A few thin high clouds drifting in from the west but mostly
clear with light to calm winds and good radiational cooling
conditions. Some patchy fog around rivers, swamps and bogs
possible by daybreak.

Lows in the mid 40s to around 50F in the valley areas and upper
30s to mid 40s over the higher terrain. Portions of the
southern Adirondacks and southern Green Mountains may have the
most widespread 30s.

&&

.SHORT TERM /6 AM THIS MORNING THROUGH MONDAY NIGHT/...
Tomorrow...the sfc anticyclone will slowly shift south and east
of New England. Low and mid level heights will rise aloft. Some
cirrus may increase from the south and west late in the
afternoon. The subsidence from the ridge will bring partly to
mostly skies with seasonable temps for Fathers Day. Max temps
will be in the mid to upper 70s in the valleys and mid 60s to
lower 70s over the higher terrain.

A warm front will move through parts of the region Sunday night
with increasing mid and high clouds. A weak short-wave will move
across the top of the mid level ridge. A few light showers or
sprinkles may move across the southern Dacks overnight. Temps
will be milder than the previous night, but still comfortably
cool with 50s to around 60F.

The week will open with sunshine mixed with clouds, as the warm
front move through during the late morning and early pm. The
low-level moisture is limited, as we kept some isolated showers
over the southern Dacks. A few sprinkles can not be ruled out
north and west of the Capital Region. Humidity levels will start
to creep up. We went close to the ECM MOS max temp values with
the low and mid level warm advection coupled with the southerly
flow. Max temps will be in the mid and upper 80s below 1000 ft
in elevation with mid 70s to lower 80s above that height.

Low and mid level heights continue to increase across the
Northeast into southeast Canada setting the stage for a hot
week. The heat will be building in from the south and west. Lows
Mon night will be in the 60s with upper 60s in the Hudson and
Mohawk Valleys.

&&

.LONG TERM /TUESDAY THROUGH SATURDAY/...
The first heat wave of 2024 for eastern NY and western New England
continues to show high probabilities of beginning on Tuesday and
continuing through much of the week with perhaps some relief by next
weekend. Anomalous ridging will build in over the East Coast by
Tuesday with H500 heights +2 to +3 STDEVs above normal based on the
NAEFS.  H850 temps rise to +18C to +20C based on the GFS/ECMWF.  Max
temps were accepted close to the NBM but slightly closer to the ECM
mean/op run with max temps in the mid and spotty upper 90s in the
valleys and mid 80s to lower 90s over the higher terrain. Heat
headlines will likely be needed with dewpoint temps in the 60s to
lower 70s. Apparent temps in the 90s to lower 100s will be possible.
Most of the coverage below 1000 ft will be in the mid 90s to lower
100s. Not much relief is expected Tue night with lows in the 60s to
around 70F with mainly clear skies and light to calm winds.

Wednesday-Thursday...the sensible weather pattern does not change
much with anomalous heights aloft combined with H850 temps around
20C. West winds may increase slightly adding some slightly higher
temps in the valley areas due to downsloping.  The combination of
the heat and humidity will likely yield heat advisories for the much
of the area with potentially spotty Excessive Heat Warnings.  Max
temps in the mid and upper 90s (near record values) will be possible
below 1000 ft in elevation with upper 80s to lower 90s over the
higher terrain. Isolated to scattered showers and thunderstorms may
pop-up if we can break any capping due to terrain differential
heating. Lows will be balmy in mid 60s to lower 70s.

Friday into the weekend...Dangerous heat and humidity likely
continues on Friday with additional heat headlines possible.  A
short-wave and a cold front may produce more scattered showers and
thunderstorms late Fri into Friday night.  The mid level flow
becomes zonal aloft over southeast Canada and the Northeast.  The
boundary will be near the region to open the weekend with some
additional chances of showers and thunderstorms possible. Temps will
continue to run above normal with 90s possible in the Hudson River
Valley into the weekend.

The heat and humidity next week will continue to be highlighted in
the Hazardous Weather Outlook text and graphical products.

.AVIATION /06Z SUNDAY THROUGH THURSDAY/...
Through 06Z Monday...VFR conditions expected to prevail through the
period at all terminals. Beneath largely clear skies overnight, some
patchy fog/mist is possible at GFL near sunrise, around 09-11Z Sun.
Otherwise, high clouds at 20-25 kft will steadily increase in
coverage as a weak disturbance passes to the north, with cigs at 15-
20 kft developing at ALB/GFL by 00Z Mon.

Calm to light and variable winds will persist through tonight, with
south to southwest winds of 4-8 kt expected to develop at all
terminals after 15-18Z Sun through the remainder of the period.

Sunday Night to Wed night: No Operational Impact. NO SIG WX.
Thursday: Low Operational Impact. Slight Chance of SHRA...TSRA.
