Heat and Damaging Winds in Connecticut, June 11 to 12, 2026

Area Forecast Discussion
National Weather Service Albany NY
655 AM EDT Thu Jun 11 2026

.WHAT HAS CHANGED...
Updated to add equivalent Slight Risk (level 2 of 5) for severe
thunderstorms Sunday for areas south and west of Albany.

Added Climate section for daily high temperature records today
and Friday. Heat Advisory for today expanded to include
southern Saratoga county, eastern Windham county in SE VT and
southern Berkshire county in SW MA. Heat Advisory for Friday
expanded to include Bennington county in SW VT. Lowered PoPs
this afternoon/evening to mainly scattered coverage of
showers/T-storms.

&&

.KEY MESSAGES...
1) Above normal temperatures and high humidity levels will
continue through Friday. Heat index values will be high enough
to allow for an increased risk in heat related illnesses in
valley areas today and much of the region on Friday.

2) There is a chance for thunderstorms today through Friday,
mainly in the afternoon and evening hours. Some storms could be
severe with damaging winds and hail. Storms may be capable of
producing heavy downpours as well.

3) Additional showers and thunderstorms are possible on Sunday
associated with another cold front. Some storms could be strong
to severe, especially south and west of Albany.

.DISCUSSION...
KEY MESSAGE 1...

First day of oppressive heat begins today, with a Heat Advisory
in effect for most valley locations from the Capital District
south and SE VT from 12-8 PM. Mostly sunny skies and westerly
flow will result in highs in the upper 80s/lower 90s. Combined
with dewpoints in the upper 60s to lower 70s, heat indices
should reach the 95-100F range in the advisory area.

The anomalously warm air mass (850 mb temperature anomalies of
+1 to +3 STDEV from NAEFS) will persist through Fri. Heat
Advisory is in effect for much of the region except for some
higher elevation areas. Highs expected to reach the lower 90s in
most valley locations, with dewpoints in the lower 70s. This
will result in fairly widespread oppressive heat indices in the
upper 90s to lower 100s in the advisory area. Slightly cooler,
but much less humid conditions will move in Fri night into Sat
behind a cold front.

KEY MESSAGE 2...

One short wave has moved east well east of the area into New
England, while another disturbance approaching from the lower
Great Lakes will result in chances for showers/T-storms. Timing
in latest guidance/CAMs looks more delayed and scattered in
coverage, occurring mainly during the evening hours. Area of
greatest instability and forcing continues to focus well south
of Albany where a Slight Risk (level 2 of 5) of severe storms
remains in effect, with a Marginal Risk (level 1 of 5) up to the
I-90 corridor. HREF showing SBCAPE of 1500-2000 J/kg in the
increasingly warm/moist air mass, although 0-6 km shear looks to
be fairly weak ~20 kt. Still, with moderate instability and
high PWATs, wet microbursts will be possible mainly in the
Slight Risk area. Locally heavy downpours will also occur with
any storms. Fortunately, guidance indicating the remnant EML
that will be over our region this morning will shift well east
out of the area by late in the day.

After a break in the convection Fri morning, there will be
renewed chances for showers/T-storm during the afternoon to
evening hours ahead of a cold front approaching from the west.
The upper trough lags a bit behind the front, so deep layer
shear only looks to increase to around 25 kt late in the day.
However, with the very warm and humid air mass still in place,
SBCAPE values could reach the 2000-3000 J/Kg range which is
quite high for our region. With forcing from the cold front,
multicell clusters/lines could produce wet microbursts. Coverage
looks greater than Thursday, with timing mostly late afternoon
to early evening based on the latest guidance. 700-500 mb lapse
rates forecast to steepen to 6.5-7.0 degC/km, so some of the
taller updrafts could produce some hail. Damaging wind gusts
will likely be the main threat though. There continues to be a
Slight Risk (level 2 of 5) for severe storms across the entire
area from the Storm Prediction Center(SPC).

KEY MESSAGE 3...

Another cold front and short wave aloft are expected to move
across the area in the Sunday afternoon to evening, although
there is low confidence in exact timing. If the front approaches
during the diurnally favored afternoon to early evening hours,
there could be some strong to severe T-storms that develop.
Strong zonal westerly flow aloft looks to result in deep layer
wind shear of potentially 40-50+ kt. Should sufficient
instability develop as the cold front approaches with
temperatures expected to be well into the 80s, storm
organization would occur. SPC has issued an equivalent Slight
Risk (level 2 of 5) for severe thunderstorms Sunday for areas
south and west of Albany.

.AVIATION /12Z THURSDAY THROUGH MONDAY/...
Through 12z Friday...VFR conditions prevail across all terminals
this morning with the exception of KPSF where MVFR visibility is
currently being reported due to light mist. This is expected to
burn off within the next hour or less, so did not include this
in the TAFs at this time.

VFR conditions are generally expected at ALB and GFL throughout
the 12z TAF cycle, as the probability of showers and
thunderstorms is lower there than at POU and PSF. Still, PROB30s
were included between 23-03z and 02-05z respectfully for the
potential for a light shower or two. At POU and PSF, showers and
thunderstorms may be more common, though confidence is still
rather low given the latest guidance. Still, PROB30 groups were
added for thunderstorms between 23-03z and 00-04z respectively.
Within any thunderstorms that form at these sites, IFR
conditions will be likely. But, once convection has concluded,
VFR conditions will gradually return late tonight.

Winds throughout the 12z cycle will prevail out of the
southwest to northwest at sustained speeds around 5-10 kt. ALB
and PSF could also see some gusts up to 20kt this afternoon.
Within any thunderstorms that develop at POU and PSF, gusts up
to 30 kt will be possible.

Outlook...

Friday Night: Moderate Operational Impact. Chance of SHRA...TSRA.
Saturday: Low Operational Impact. Breezy. NO SIG WX.
Saturday Night: No Operational Impact. NO SIG WX.
Sunday: Moderate Operational Impact. Breezy. Chance of SHRA...TSRA.
Sunday Night: High Operational Impact. Definite SHRA...TSRA.
Monday: No Operational Impact. NO SIG WX.
Monday Night: No Operational Impact. NO SIG WX.
Tuesday: Low Operational Impact. Slight Chance of SHRA.
