The radar
The Albany radar (KENX), 82 km from the middle of the area, began a volume at 00:36 UTC, the scan nearest the moment this went out.

The archived warnings, watches and discussions in force at that minute are drawn over the scan, this one among them.
Did it verify
Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this flash flood warning while it was in force. That is not proof nothing happened: reports are thin where few people live.
Cow counts a report within 15 km of the polygon while the warning was in force: a tornado for a tornado warning; hail of 1 inch or more, a gust of 58 mph or more or wind damage for a severe thunderstorm warning; a flash flood report for a flash flood warning.
The nearest sounding before it
Albany, NY (KALY), launched 00:00Z, 0.6 hours before the alert went out and 97 km from the middle of its area. This is the routine balloon launch nearest before it, the air the forecaster had in hand, not a measurement taken for the alert.

07What forecasters said that day
The local office's own words before this flash flood warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Albany, NY wrote its last area forecast discussion before this flash flood warning went out at Jul 1, 7:28 PM EDT, 1 hour 7 minutes earlier. Its key messages:
- 1) The combination of hot temperatures and high humidity will lead to an increased risk for heat-related illnesses today through Saturday, when HeatRisk impacts will likely reach the Major to locally Extreme Categories. 2) Thunderstorms are possible each of the next several days, with the greatest coverage expected today and Saturday. Some storms may be strong to severe today with damaging winds and hail up to 1 inch.

Area Forecast Discussion
National Weather Service Albany NY
728 PM EDT Wed Jul 1 2026
.WHAT HAS CHANGED...
Quick update to expand the severe thunderstorm watch #432 to
include Albany, Montgomery, Schenectady and Rensselaer counties.
A cluster of strong to severe storms have developed in the
Capital Region just south of the initial watch. These storms
have potential to produce damaging winds gusts and isolated
large hail. The watch is in effect until 11 pm.
07
Minor adjustment to probability of precipitation for this
afternoon into tonight as showers and thunderstorms continue to
develop this afternoon and this evening. Otherwise, no changes
made to the current forecast.

.KEY MESSAGES...
1) The combination of hot temperatures and high humidity will lead
to an increased risk for heat-related illnesses today through
Saturday, when HeatRisk impacts will likely reach the Major to
locally Extreme Categories.
2) Thunderstorms are possible each of the next several days, with
the greatest coverage expected today and Saturday. Some storms may
be strong to severe today with damaging winds and hail up to 1
inch.
&&
.DISCUSSION...
KEY MESSAGE 1...
As of 2:30 PM...Dangerous heat continues through Friday across
eastern New York and western New England. Heat headlines
continue for all of eastern New York and western New England.
Surface observations continue to show widespread heat index
(feels-like temperatures) values ranging between 95 and 115
degrees across eastern New York and western New England. Actual
air temperatures range in the low to upper 90s in eastern New
York and western New England valley locations. Thursday is still
on track to be the hottest day this week with highs in the low
to upper 90s. Poughkeepsie area has the greatest risk of
reaching over 100 degrees tomorrow afternoon if plenty of
morning and afternoon sunshine occurs. Continue to have multiple
ways of staying cool and staying hydrated.
Previous Discussion...Friday and Saturday, the ridge begins to
weaken. Both days will remain quite hot, with highs Friday again
well into the 90s for most valley areas. A very weak cold
frontal boundary will track across the region Friday, which
could result in a few more clouds and some isolated convection.
With temps and dew points a couple degrees lower than the
previous days, some areas in the extreme heat warning may be
able to be downgraded to advisories for Friday. Saturday,
temperatures will be more in the low to mid 90s with more
convection around, but additional heat advisories will likely be
needed. A stronger cold front tracks through the region
Saturday night into Sunday as the ridge aloft continues to break
down. Temperatures Sunday into the first half of next week
likely remain above normal with mid and upper 80s (low 90s
possible Sunday in the Mid Hudson Valley), but heat indices
should remain below advisory criteria Sunday onwards.
KEY MESSAGE 2...
As of 2:30 PM...Based on latest analysis of the 18z ALY
sounding, the current environment is favorable for thunderstorms
to develop into this evening. A few storms could become severe
through 8 PM tonight, with primary concerns being 60+ mph winds
and hail up to 1 inch. Where storms develops continues to be the
low confidence portion of the equation today, as they could be
isolated and highly localized if storms get enough energy.
Confidence continues to increase for the severe threat to end by
8 PM, but between 8 PM and midnight there could be additional
showers and thunderstorms as conditions are favorable for
lingering storms. Nevertheless, have multiple ways to receive
warnings and be prepared to head indoors when thunder roars.
Previous Discussion...Forcing is less evident compared to
yesterday, but guidance does show a couple ripples moving
overtop the upper ridge. While the cap will be stronger than
yesterday, it does not look quite as strong as some previous
guidance was suggesting it might be. With numerous OFBs leftover
from the overnight convection, this should provide enough
forcing for isolated to scattered thunderstorms to develop this
afternoon. Shear will be less impressive than yesterday and
hodographs are shorter, so will likely see some loosely
organized clusters as opposed to more coherent line segments
like yesterday. That said, CAPE values >3000J/kg and DCAPE >1000
J/kg will lead to a damaging wind threat with any stronger
storms. Despite high freezing levels, impressive cape through
the HGZ and steep lapse rates could allow for some large hail as
well.
Convective threat looks lower Thursday, with more capping, the
ridge axis a little closer, and the better upper forcing
displaced north of the region. SPC has a marginal risk for
portions of the southern ADKs, likely due to high to extreme
CAPE again and slightly more shear, but the threat is very
conditional upon some sort of trigger mechanism being able to
break the CAP.
Additional convection is possible each day Friday through
Sunday, with the best coverage Saturday ahead of an approaching
cold front. Each day will still feature plenty of instability,
with strengthening mid and upper westerly flow as the ridge
breaks down, so some stronger storms may be possible, although
details remain fuzzy this far out in time.
&&
.AVIATION /00Z THURSDAY THROUGH MONDAY/...
Through 00z Friday...VFR conditions in place early this evening,
however there are scattered TSRA in the area, with the best
chances of the storms moving across KALB between 00z-02z so a
TEMPO is mentioned there. Lower probs at KGFL/KPSF where TSRA
may occur through around 03z-04z. Any TSRA could produce brief
MVFR/IFR vsby. Once the storms end, it will be a warm and humid
night, with possible fog and IFR conditions developing
especially at KGFL/KPSF, where TEMPOs are mentioned. Lower
confidence in fog at KALB, so will mention MVFR vsby for now.
Any fog should dissipate by 11z, with VFR conditions returning.
Isolated TSRA possible Thursday afternoon, but are expected to
be too sparse to include in TAFs at this time. Winds will be
light and variable tonight outside TSRA. Winds will become
westerly and increase to 9-13 kt with gusts to around 20 kt
Thursday afternoon.
Outlook...
Thursday Night: No Operational Impact. NO SIG WX.
Friday: Low Operational Impact. Breezy. NO SIG WX.
Friday Night: No Operational Impact. NO SIG WX.
Independence Day: Moderate Operational Impact. Chance of SHRA...TSRA.
Saturday Night: Low Operational Impact. Slight Chance of SHRA.
Sunday: Moderate Operational Impact. Chance of SHRA...TSRA.
Sunday Night: Moderate Operational Impact. Chance of SHRA...TSRA.
Monday: Moderate Operational Impact. Likely SHRA...TSRA.
