What was reported inside it

TimeReportWhereRemark
Jul 5, 7:07 PM EDTFLASH FLOOD2 Ene Port Royal, PAWater flowing across a stretch of old Route 22 in Walker Township.

Local storm reports filed while the alert was in force, from inside its polygon or its counties.

Did it verify

Verified. The Iowa Environmental Mesonet's Cow matched one storm report to this flash flood warning; the first came 45 minutes after it went out.

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.

BULLETIN - EAS ACTIVATION REQUESTED
Flash Flood Warning
National Weather Service State College PA
622 PM EDT Sun Jul 5 2026

The National Weather Service in State College has issued a

* Flash Flood Warning for...
  Central Juniata County in central Pennsylvania...
  Central Perry County in south central Pennsylvania...

* Until 930 PM EDT.

* At 622 PM EDT, Doppler radar indicated thunderstorms producing 
  heavy rain across the warned area. Between 1 and 3 inches of rain 
  have fallen. Additional rainfall amounts of 1 to 2 inches are 
  possible in the warned area. Flash flooding is ongoing or expected 
  to begin shortly.

  HAZARD...Flash flooding caused by thunderstorms.

  SOURCE...Radar.

  IMPACT...Flash flooding of small creeks and streams, urban
           areas, highways, streets and underpasses as well as
           other poor drainage and low-lying areas.

* Some locations that will experience flash flooding include...
  Newport, New Bloomfield, Mcalisterville, Spruce Hill, Mexico, 
  Ickesburg, Loysville, Walnut, Mifflintown, Port Royal, 
  Thompsontown, Mifflin, Blain, Landisburg and East Salem.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

Turn around, don't drown when encountering flooded roads. Most flood 
deaths occur in vehicles.

Be aware of your surroundings and do not drive on flooded roads.

In hilly terrain there are hundreds of low water crossings which are 
potentially dangerous in heavy rain. Do not attempt to cross flooded 
roads. Find an alternate route.

What 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 State College, PA wrote its last area forecast discussion before this flash flood warning went out at Jul 5, 3:04 PM EDT, 3 hours 18 minutes earlier. Its key messages:

  • 1) Breakdown of heat wave pattern gives rise to severe storms and torrential downpours today and tonight; flood risk lingering in the east on Monday.

.WHAT HAS CHANGED...
* Targeted Moderate Risk Excessive Rainfall Outlook (level 3/4)
  for east-central Pennsylvania through tonight
* Flood Watch issued this afternoon through Monday for east-
  central Pennsylvania

&&

.KEY MESSAGES...
1) Breakdown of heat wave pattern gives rise to
severe storms and torrential downpours today and tonight; flood
risk lingering in the east on Monday.

&&

.DISCUSSION...
KEY MESSAGE 1: Breakdown of heat wave pattern gives rise to
severe storms and torrential downpours today and tonight; flood
risk lingering in the east on Monday.

40 severe thunderstorm warnings issued in the past 2 days. The
days following a transition from an extreme heat pattern are
often marked by severe/active weather, and that trend continues
through at least Monday. As the heat dome shifts to the west and
troughing develops over the Great Lakes/Ohio Valley/Northeast, the
upcoming week will feature relatively cooler (more seasonal)
temperatures with a bullish signal for almost daily rain chances
particularly early and late in the week.

Another active wx day ahead with dual severe T-storm and flash
flood risks. We anticipate another diurnal uptick in convective
development within a very warm, moist and increasingly unstable
environment indicative of steep low-mid level lapse rates.
Pockets of stronger deep layer shear 30+ kt may exist in the
upper OH Valley and eastern PA, but the general expectation is
for pulse to multicell storms to once again merge/form into line
segments with some cold pool organization to promote damaging
wind potential from mid afternoon into the evening. Terrain
boundaries will also play an important role in initiating/organizing
convection given lack of other strong forcing. SPC placed the
highest damaging wind probs near/southeast of I81/78 where max
temps should reach 90F.

Focus will evolve from severe to flash flood/hydro ops by later
this evening and continue into Monday as a robust +RA signal
continues to manifest over east-central PA. Atmos conditions
will be quite favorable for heavy rainfall and flash flooding
potential with 2+ inch pwats correlating to intense rain rates
>2 in/hr. Still some question on degree of repeating/back-
building storms along q-stnry/wavy frontal zone. Latest
HREF/REFS mean QPF guidance is signaling 1-3" in the 24hr period
ending 00Z Tue with PMM/LPMM max values exceeding 5 inches. WPC
coordinated a targeted and relatively small moderate excessive
rainfall outlook (level 3/4) within a broader level 2/4 or SLGT
risk area. We issued a relatively large/broad flood watch along
with WFO PHI as there remains some spatial uncertainty to
exactly where the greatest rainfall will occur. The setup
(multiple rounds of slow moving/torrential downpours) favors
locally significant flash flooding particularly in terrain areas
and highly urbanized corridors. One limiting factor is
obviously the drought conditions and corresponding elevated FFG
values that may offset the overall risk to some extent.

&&

.AVIATION /18Z SUNDAY THROUGH FRIDAY/...
Showers and thunderstorms will develop during the afternoon and
are once again likely to impact all TAF sites through the
evening. PROB30s have been included to highlight this potential,
though the timing will need to be adjusted as confidence
increases. Storms will be capable of producing strong wind
gusts, intense rainfall rates, and frequent lightning. Any
storms that move directly over an airfield will likely lead to
brief periods of IFR conditions.

Much of the heavier showers and thunderstorms come to an end
from west to east between 00z and 06 Mon, though lighter showers
may linger past 06Z. Fog and low clouds appear likely behind
these showers and widespread IFR conditions will be likely into
Monday morning as easterly upslope flow provides ample
moisture.

Outlook...

Mon-Tue...Restrictions possible in A.M. fog and P.M. T-storms.
Wed-Fri...Restrictions possible in showers/storms, most
widespread on Friday.

&&

.CLIMATE...
Rare Heat at Harrisburg: 3 consecutive days with maxT >= 100F
from July 2-4, 2026. The last time this streak occurred was
July 1999 (2x) and is only the 6th time on record going back to
1888.
