Mesoscale Precipitation Discussion 0886
NWS Weather Prediction Center College Park MD
543 AM EDT Wed Jul 29 2026

Areas affected...Long Island, far northern NJ into eastern NY and
southern New England

Concerning...Heavy rainfall...Flash flooding likely

Valid 290942Z - 291515Z

Summary...Slow moving showers and thunderstorms will continue to
produce areas of flash flooding across eastern NY into southern
New England and Long Island this morning. Slow moving areas of
heavy rain are expected to produce an additional 3 to 5 inches of
rain in some locations through 15Z (11 AM EDT).

Discussion...Area radar imagery at 0915Z showed a slow moving
corridor of heavy rain impacting the Hudson Valley containing
observed hourly rainfall of 1-2 inches (locally higher). Farther
south, another axis of heavy rain was slowly pivoting east across
central Suffolk County into western CT. Despite weak instability
of about 500 J/kg or less, the region remained in a favorable
environment for heavy rain, positioned just ahead of a slow moving
low aloft with numerous mid-level vortices helping to focus
locally higher rainfall rates over inland locations. A surface/850
mb low has become rather well defined about 25 miles south of
Farmingdale, with 25-35 kt of southerly to south-southeasterly
925-850 mb flow transporting PWs of 1.7 to 2.0 inches across Long
Island into southwestern CT and eastern NY. Similarly oriented low
level and deeper layer steering flow has promoted training and
repeating rounds of heavy rain beneath diffluent and divergent
flow just east of the upper low over northeastern PA.

Short term forecasts from the RAP show the 850 mb low slowly
tracking north over the next 6 hours with the low level moisture
transport axis to its east pivoting eastward across Long Island
into southern New England. By 15Z, the low should be over
southwestern CT with low level southeasterly to easterly winds
across southern New England converging into a deformation zone
along the eastern NY border with CT/MA. It is here that the
highest additional rainfall totals may occur with slow moving
hourly rainfall values of 1 to 2+ inches over multiple hours.
While a single location may not see 1 to 2+ in/hr rainfall
continuously, the eastern NY into southwestern New England region
will be in a favorable location for periodic occurrences of higher
rainfall intensities. Terrain influences may factor into flash
flood severity. Given locally heavy rain across eastern NY into
portions of New England over the past 24-28 hours, flash flooding
could be locally significant this morning. Areas of flash flooding
will continue to be likely this morning with likely disruptions to
the morning commute and across locations of sensitive terrain.

Area Forecast Discussion
National Weather Service Cleveland OH
236 PM EDT Tue Jul 28 2026

.WHAT HAS CHANGED...
No major changes to the ongoing forecast.

&&

.KEY MESSAGES...
1) Cooler and less humid the rest of the week with occasional widely 
scattered showers in far NE Ohio and NW PA through tonight.

2) Turning warmer and more humid this weekend into the start of next 
week with scattered showers and thunderstorms, but confidence in 
coverage is low.

&&

.DISCUSSION...
KEY MESSAGE 1...
Afternoon satellite and water vapor loops show the 
mid/upper trough deepening and becoming negatively tilted across the 
Great Lakes and Northeast CONUS. Current RAP analysis places the 
surface low over western New York, with the trailing cold front 
approaching the U.S. 30 corridor. A band of scattered showers along 
and ahead of the front driven by weak instability and low-level 
convergence is exiting a Mahoning to Knox County line. Expect most 
of the showers to be done by the time the front exits late this 
afternoon, but lingered some slight chance POPS through late 
afternoon due to diurnal heating and progressively cooler air aloft 
that could trigger an isolated shower or two. Dew points remain 
elevated this afternoon, but a secondary surface trough currently 
crossing the lake will start to bring in the true airmass change 
this evening.

For tonight, most areas will stay dry as the drier airmass continues 
to advect in, but the surface low will become vertically stacked 
beneath the closing off mid-level low over upstate New York. This 
will lead to a deepening cyclonic flow cold air advection pattern 
which should produce scattered lake enhanced rain showers in far NE 
Ohio and NW PA. Wraparound moisture supports the idea of some 
showers, but RAP forecast soundings show lake to 850 mb Delta T's 
only averaging about 10 C along with shallow moisture profiles 
confined below 800 mb. An inversion will also be present around 800 
mb, so this shallow moisture and low inversion environment will keep 
the rain showers light and disorganized. With this all being said, 
limited POPS to slight chance in far NE Ohio and NW PA tonight. 

By Wednesday, the drier air should win out and allow any lake 
showers to end as the closed low gradually drifts farther east and 
Canadian high pressure builds in from the Upper Midwest. This high 
will settle over the Lower Great Lakes and Ohio Valley Thursday into 
Friday allowing the pleasant temperatures and low humidity to 
continue through the end of the week. Lows in the mid 50s away from 
the lake both Thursday and Friday mornings will give the air 
conditioners a nice break. 

 
KEY MESSAGE 2...
The Canadian high will shift into the Mid Atlantic 
region this weekend allowing return southerly flow to develop as the 
old closed low over the NE U.S weakens and lifts out. At the same 
time, another northern stream mid/upper shortwave trough will drop 
out of the Upper Midwest Saturday and evolve into a closed low over 
the Ohio and Tennessee Valleys by Sunday. Deterministic and 
ensemble guidance is struggling with the exact evolution and 
ultimate track of this closed low and how long it will linger, 
which is common in these set ups. Confidence is highest in a 
return to warmer and more humid conditions given the enhanced 
warm air advection between the high to the east and closed low 
diving to the west, but coverage of convection in this airmass 
is much lower confidence. Kept NBM chance POPS Saturday through 
Tuesday at this time, with the greatest coverage during daytime 
heating. Some areas that have missed out on rain the past couple
of weeks may see some with the scattered convection between 
this weekend and early next week as we turn the calendar to 
August.

&&

.AVIATION /18Z Tuesday THROUGH Sunday/...
SCT/BKN cumulus field remains in place this afternoon with
ceilings generally in the 2,500-5,000 ft range. Skies should
tend to become FEW/SCT through this evening, especially west of
I-77. Some lake effect/enhanced clouds will redevelop this 
evening into tonight following the passage of a secondary cold 
front, with additional MVFR clouds expected for parts of 
Northeast Ohio and Northwest Pennsylvania late tonight. MVFR 
clouds should mostly clear up by daybreak with VFR conditions 
expected with FEW/SCT cumulus clouds during the day Wednesday.

Northerly winds around 10-13 knots with gusts to 20 knots
expected this afternoon and again tomorrow, with light winds of
around 5 knots overnight.

Outlook...Non-VFR possible in scattered showers and 
thunderstorms Saturday afternoon through Sunday.

&&

.MARINE...
Scattered thunderstorms will push southeast across Lake Erie
through early this morning with locally higher winds and waves 
possible. Otherwise, elevated southwesterly to westerly winds 
15-20 knots will become northerly at 15-25 knots by daybreak as
a cold front sinks south across the lake. Onshore flow will 
allow for wave heights in the central and eastern basins to 
build to 4-7 feet. Highest winds and waves will be in the 
central basin. Small Craft Advisories and Beach Hazards 
Statements remain in effect to highlight the timeframe of 
highest risk to small craft and beach goers through Wednesday 
evening. 

Northwest winds decrease to 10-15 knots Thursday as high 
pressure approaches from the west. Light and variable flow 
returns Friday with largely offshore light winds anticipated 
into the weekend.
