What forecasters said that day

The local office's own words before this severe thunderstorm warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Buffalo, NY wrote its last area forecast discussion before this severe thunderstorm warning went out at Aug 2, 2:33 AM EDT, 9 hours 59 minutes earlier. Its key messages:

  • 1) Multiple rounds of showers and thunderstorms are expected through tonight, with scattered instances of flash flooding possible. 2) Unsettled weather moves back into the region Wednesday through the end of the week.
Area forecast discussion, Aug 2, 2:33 AM EDT, 9 hours 59 minutes before
Area Forecast Discussion
National Weather Service Buffalo NY
233 AM EDT Sun Aug 2 2026

.WHAT HAS CHANGED...
Flood Watch issued for all of western and north central New York
from 10 AM today to 2 AM Monday.

&&

.KEY MESSAGES...
1) Multiple rounds of showers and thunderstorms are expected through
tonight, with scattered instances of flash flooding possible.

2) Unsettled weather moves back into the region Wednesday through
the end of the week.

&&

.DISCUSSION...
Key Message 1...Multiple rounds of showers and thunderstorms are
expected through tonight, with scattered instances of flash flooding
possible.

A deep southerly flow with a plume of Gulf moisture will arrive
across the forecast area today. A wavy cold front will settle
across far western New York to the Saint Lawrence River through
this afternoon and will be the focus for heavy showers and
thunderstorms through this evening. Large scale ascent will aid
diurnally driven convection within a corridor of high moisture
content and deep (>11kft) warm cloud depths. Southerly winds
will be parallel to the front and result in the potential for
backbuilding/training as well as repeated rounds of storms.

A low pressure wave is expected to move along the frontal boundary
across the forecast area tonight, while remaining ahead of the
mid level trough axis. The core of the highest PWATS will shift
east tonight. Heavy showers and thunderstorms are expected
across the region with localized areas of heavy rainfall from
the Genesee Valley to the eastern Lake Ontario region.

Latest guidance continues to suggest the axis of heaviest rain is
across far western New York to the Saint Lawrence River. Basin
average rainfall amounts will range from 1-2" near this axis to 0.5-
1" farther east. Localized higher amounts of 3+ inches are possible.
Efficient rainfall rates and repeated rounds of showers/storms
from the slow moving system could result in localized flash
flooding through tonight, especially for urban areas and poor
drainage areas. A Flood Watch is in effect from 10 AM today
through 2 AM Monday.

Conditions will improve from west to east on Monday. The surface low
is expected to deepen as a shortwave trough drops south from Canada
Monday. Showers and thunderstorms with heavy rain are possible
across the eastern Lake Ontario region through Monday afternoon.
High pressure builds across the region Monday night through Tuesday
night resulting in dry weather.

Key Message 2...Unsettled weather moves back into the region
Wednesday through the end of the week.

The chance for showers and thunderstorms return to the region
Wednesday through Friday. An upper level trough will move into the
Great Lakes region and a return flow will bring moisture northward.
The synoptic pattern suggests deep southwesterly flow will persist
during this time. While confidence is low regarding timing and
intensity of showers and thunderstorms, chances are higher in the
afternoon to evening.

&&

.AVIATION /06Z SUNDAY THROUGH THURSDAY/...
VFR flight conditions to start the TAF cycle, but a storm system to
our south will further increase moisture to the TAF region, which
will bring a widespread MVFR to low end VFR flight conditions along
with periods of rain showers and perhaps a thunderstorm. Activity is
expected to be heaviest near KIAG/KBUF in vicinity of the stalling
frontal boundary today, with this activity persisting through the
remainder of the TAF cycle. An additional wave of heavier rain
across the Southern Tier and Genesee Valley this afternoon and
evening hours may impact KJHW and KROC. Downburst of rain will
likely bring IFR visibilities.

Outlook...

Monday through Thursday...Mainly VFR, however afternoon and evening
scattered showers and thunderstorms will pose a risk for MVFR
conditions at times.

&&

.MARINE...
A wavy cold front will slowly ease its way east from the central
Great Lakes and across Lakes Erie and Ontario through Monday. A
generally light to modest south to southeasterly flow out ahead
of the front will give way to a northerly/northeasterly flow of
similar strength following its passage.

Of more concern to marine interests will be the showers and
thunderstorms today and tonight that are expected to accompany the
approach and passage of the front, some of which could contain
locally heavy downpours/greatly reduced visibility and locally
higher winds and waves.
