The episode as NWS BGM wrote it up.
A weak area of low pressure moved into Northeastern Pennsylvania during the afternoon which provided a focus for heavy rain-producing thunderstorms. Several storms moved through the Wilkes-Barre and Scranton metro areas during the afternoon causing significant urban flash flooding of poor drainage and storm drain systems. Many roads were flooded in the area with several reports of stranded vehicles in the area.

NWS Binghamton, NY wrote its last area forecast discussion before the first event at Aug 13, 12:51 PM EST, 13 minutes earlier.
Area Forecast Discussion National Weather Service Binghamton NY 151 PM EDT Wed Aug 13 2025 .SYNOPSIS... Isolated showers and thunderstorms will be possible tonight and tomorrow. Quieter conditions and warmer temperatures return at the end of the week and into the start of the weekend. A frontal system will move through on Sunday with rain and cooler temperatures. && .DISCUSSION... Key Messages: - Front pushes through this afternoon with showers and storms continuing through Thursday - Trending warmer through the first half of the weekend, next frontal system moves through on Sunday -Becoming fall-like next week with low chances for showers, especially Tuesday Discussion: A slow moving cold front will continue to push through this afternoon and evening. The band of showers from this morning has now transitioned to scattered thunderstorms. The environment is rich with moisture as PWATs ware 1.8 and higher. With these storms, one concern will be heavy rain, though with how dry it has been, any localized hydro issues would likely be limited to the urban areas. Strong storms are not expected today even though models were showing CAPE values as high as 2000 J/kg this afternoon. Shear is lacking though, as are the mid-level lapse rates which has been a common theme for the late summer convective systems. Lightning network observations have shown that these storms are producing a fair amount of lightning, so that will be another concern especially for those with any outdoor plans. Models try to kick off some more showers late today though forcing does not look to be too great. For PoPs, a blend of the NBM, HREF, and Conshort was used. Behind this front, temperatures have fallen over CNY but are beginning to recover as skies are becoming partly cloudy. Some lingering showers will be possible tonight. With the added moisture and light winds, patchy to areas of fog is expected. The one uncertainty is cloud cover as skies will be slow to clear out. Despite this, the best chances for fog will be where it rains or has rained today. Temperatures will be mild, only falling into the upper 50s and 60s. A weak shortwave will move through tomorrow and may kick off a few showers and thunderstorms. Instability and shear will be weak, so any thunderstorms that can develop will be sub-severe. Otherwise, high pressure will begin to build in and lead to quieter conditions through at least the first half of the weekend. Temperatures will also begin to trend warmer through Saturday with the potential return of 90s in urban and valley locations. Conditions may become slightly humid with dewpoints in the 60s but those would be low enough to keep heat index values below advisory criteria. Another frontal system will move through on Sunday and bring the next chance for more widespread showers and thunderstorms. Long range guidance show some instability but weak shear once again, though it is too early to determine if stronger storms will be possible. This front will help bring temperatures back down into the 70s and 80s with fall-like conditions by midweek. Some showers will be possible on Monday but chances look better on Tuesday as the next system moves into the region. If model guidance stays consistent with the timing of this system, this should keep what is currently Tropical Storm Erin over the Atlantic. && .AVIATION /18Z WEDNESDAY THROUGH MONDAY/... Showers and storms currently off to our west will move into the area in the next couple of hours. SYR and RME look to have the best chance for morning rain, but restrictions are not expected. Scattered thunderstorms should develop this afternoon, with ELM/ITH/BGM/AVP having the best chance to see storms from around 17z-23z. TEMPO MVFR visby will be possible this afternoon at these terminals. IFR visby cannot be ruled out as some of these storms could produce heavy downpours, but confidence in the location and timing of the storms is too low to include IFR in the TAFs. SYR and RME could have a few storms this afternoon, but most of the activity is currently progged to be south of the terminals. Fog may develop tonight, especially at terminals where rain fell during the day. ELM has the best chance for seeing IFR conditions due to fog and this was included in the TAF. Guidance is showing signals for IFR restrictions due to fog at all of our terminals, but confidence is not high enough at this time to include it in the other TAFs as it will depend on on whether or not a good dose of rain fell during the day. Outlook... Thursday through Saturday...Mainly VFR. Sunday...VFR/MVFR with a chance of showers/t-storms along another frontal passage. && .BGM WATCHES/WARNINGS/ADVISORIES... PA...None.
