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 11 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.
The nearest sounding before it
Washington/Dulle, VA (KIAD), launched 12:00Z, 10.3 hours before the alert went out and 129 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.

BanghoffWhat 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 Jun 17, 3:24 PM EDT, 2 hours 55 minutes earlier.
Area forecast discussion, Jun 17, 3:24 PM EDT, 2 hours 55 minutes before
Area Forecast Discussion National Weather Service State College PA 324 PM EDT Tue Jun 17 2025 .SYNOPSIS... * Scattered to numerous instances of flash flooding possible this afternoon into early tonight across southwestern and south central PA * Strong to potentially severe thunderstorms possible Thursday afternoon * First significant heat wave to the season expected Sunday into early week with Major Heat Risk forecast (level 3 of 4) && .NEAR TERM /UNTIL 6 AM WEDNESDAY MORNING/... Convective activity has begun to overspread southwest PA with some clearing noted on the latest satellite imagery. Sufficient, but not significant, low-level shear could support a brief tornado across south central PA. Any spin ups would be short- lived. The far more notable concern today is the potential for numerous flash floods with significant events possible. An extremely moist near- record PW environment for mid June will support a moderate risk excessive rainfall outlook (level 3 out of 4 ERO) which [since 2009] has only occurred 5-6 days a year or less than 2% of days annually. Very moist southwesterly return flow from the Gulf - pinched between Bermuda-type ridge off the southeast coast and digging trough tracking east from the mid Mississippi Valley - will interact with multiple mid level shortwave impulses and a wavering sfc front to produce enhanced isentropic ascent supportive of heavy convective rainfall this afternoon into early tonight. The high-res CAMs and Warn on Forecast System output are in good agreement in targeting parts of southwest/southcentral PA with increasing coverage of heavy t-storm downpours during peak afternoon/evening heating. The heaviest rainfall corridor is expected to be south of I-80, west of US-15, and north of I-76. Although storm motions are expected to be somewhat progressive to the northeast based on 20-30kt mean wind, the magnitude of deep layer moisture available to tap will be close to/if not at record levels for mid June with PWs approaching 2 inches. The near-record PW and deep warm cloud depths of 13000-14000 ft will support hourly rainfall that has a chance (20-40%) of exceeding 2"/hr, with sub-hourly rain rates of 3-4"/hr possible. Despite a lack of organization, repeating rounds of thunderstorms with these intense rain rates could produce stripes of rainfall exceeding 3" (50-60%) and locally 5" (20-30%) with the greatest potential for the higher accumulations suggested by both HREF and REFS guidance occurring over CPA. With FFG extremely compromised and reduced to 0.75" or less/1hr in some areas, WPC has upgraded to a MDT risk for excessive rainfall. Given the strong +RA signal and background antecedent conditions, a flood watch was an easy decision to highlight and message what could be a potential higher-end flooding day in CPA. A majority of the rainfall is progged to fall within the Juniata River basin. River flooding is possible in that area overnight into Wednesday morning with a quick, several-foot rise in river levels as rain moves through. After somewhat of a lull in rain coverage/intensity after 03Z or 11pm, high-res ensemble guidance favors an uptick on shower activity through early Wednesday morning across the western Alleghenies which appears tied to a trailing shortwave impulse. && .SHORT TERM /6 AM WEDNESDAY MORNING THROUGH FRIDAY NIGHT/... Another midlevel shortwave trough is fcst to move through the central Appalachians by 00Z Thu along the northwest periphery of the upper level ridge off the Carolina coast. Rather strong heating of a moist environment will result in moderate to strong buoyancy Wednesday afternoon particularly across southeast PA. Scattered diurnal storm development will be possible with guidance generally depicting a belt of 35-45 kt midlevel flow across the region. This modest flow enhancement could result in some storm organization, with large PW and steepened low-level lapse rates resulting in a threat for at least isolated damaging wind. The D2 MRGL risk SWO clips the eastern portion of the lower Susquehanna Valley. By Thursday, a seasonably deep 500mb trough will move across the Great Lakes into the Northeast CONUS. With rich moisture already in place, it won't take much heating to drive thunderstorm development Thursday afternoon ahead of and along an approaching cold front. Timing of the cold front still varies somewhat which adds an element of uncertainty to the severe storm potential. That being said, SPC transitioned the D4 15% severe prob to a D3 SLGT risk SWO which essentially covers the southeastern 1/2 of CWA. Higher confidence outcome is the front clears the area Thursday night which will bring drier/less humid conditions to close out the week an officially kick of astronomical summer (see climate section). && .LONG TERM /SATURDAY THROUGH TUESDAY/... As upper ridging builds in, a capping inversion will limit any shower/thunderstorm chances to sub 20 pct for Sat-Mon. By Sunday, highs in the low to mid 90s are becoming more likely as a very strong ridge of high pressure with 500mb heights approaching 600dm builds overhead. NAEFS guidance depicts a ~72 hour period of anomalous 500mb heights, 700mb temperatures, and 850/925mb specific humidity values (>99th percentile for this time of year). If such a forecast materializes, we could be looking at a several day stretch of extreme heat and humidity across the region. Monday looks to be the hottest day of the stretch, with highs currently forecast in the 90s for most of the area. Dewpoints in the mid 70s would push heat index values over 100F for most locations east of I-99 and south of I-80, with values approaching 105+ in the Lower Susquehanna Valley. Although this forecast is still several days out and uncertainty remains, the fact that we have been in a stretch of relatively cool conditions means the quick switch into significant heat and humidity could exacerbate the risk for heat-related impacts. In addition to warm afternoon temperatures and heat index values, overnight lows will provide little to no relief from the heat. With the expected stretch of hot and humid conditions, those with heightened susceptibility to heat, such as young children, older adults, people with chronic medical conditions, and pregnant women, should prepare to limit time outdoors, wear light clothing, and drink plenty of water later this weekend and early next week. && .AVIATION /19Z TUESDAY THROUGH SUNDAY/... As of 19z, MVFR to IFR cigs blanketed central PA, with satellite imagery showing any improvement confined to Somerset County. Showers and thunderstorms will become more numerous, with the heaviest activity in the afternoon hours expected around JST. The heaviest rain is expected prior to 02z Wed. Later tonight, cigs are expected to lower across much of the area, with IFR to LIFR conds expected for most airfields. The highest chance for LIFR cigs (30-40 pct) will be across the southeast (MDT, LNS). Conditions will generally improve into Wed afternoon, with most sites improving to MVFR. Showers and thunderstorms are expected again Wed afternoon. Outlook... Thu...Predominantly VFR, although strong PM t-storms are possible with a cold frontal passage. Fri...Predominantly VFR, with a slight chance of a rain shower north. Sat-Sun...Mainly VFR. Hot. && .CLIMATE...
