I can remember we used to have them years ago. And it seemed to occur during around the last week of July, not the first week of September. Also I remember September 2011 Labor day evening had heavy drenching Thunderstorms that dumped over 2 in. Of rain in a very short time on the drought stricken area. My creek came up 3 feet from that thunderstorm. Then a few days later Lee showed up...the rest is history.

256 FXUS61 KCTP 031135 AFDCTP Area Forecast Discussion National Weather Service State College PA 735 AM EDT Thu Sep 3 2026 .WHAT HAS CHANGED... * Issued a Flash Flood Watch for all of our CWA through Midnight this Thursday night. && .KEY MESSAGES... 1) Late summer surge of heat and humidity continues with a severe thunderstorm and excessive rainfall threat through this Thursday evening && .DISCUSSION... KEY MESSAGE 1: Late summer surge of heat and humidity continues with a severe thunderstorm and excessive rainfall threat through this Thursday evening Main change this forecast cycle was to issue a Flash Flood Watch for the entire CWA based on the current wide distribution of moderate to heavy rain and embedded/training TSRA along with a HREF/NAM/MRMS blend of short range model guidance and remote sensing. A seemingly endless train of mid/upper level impulses riding ESE along the southern edge of a persistent jet and within a region of broad upper level diffluence and anomalously high PWATs of nearly 2 inches will continue to interact with numerous, converging convective outflow boundaries to produce several more bouts of heavy showers/TSRA today through at least early tonight. Basin "Average" rainfall across the CWA will likely range between 0.75 to 1.25 inches but as we saw Wed/Wednesday night, training/and back-building TSRA could easily dump over 3 inches of rain in just an hour and lead to significant flash flooding. The target areas for the heaviest rainfall today and this evening should be the Southwest half of the CWA as a well- defined outflow boundary has pushed into southern PA early today. We do expect the airmass to recover quickly late this morning/early this afternoon as this first MCS moves SE. However, a glance just to the left shows another developing MCS close on its heels over West-Central Lake Erie. This feature is progged by high res near term model guidance to track SE twd the laurel and diminish by 14-15Z. By 19-20Z today, more TSRA fire across Northern PA and a second larger area follows for this evening over a similar part of the state that experience the heavy rain over the past 24 hours. Additionally, increased southwest to westerly flow today will continue to pump in the late summer heat and very high dewpoints. A heat advisory remains in effect from 11a-8p Thursday across a portion of south central PA where max heat index values are projected to reach/exceed 100F. As mentioned above, SPC`s severe risk are will encompass primarily the SW half of the state where ML CAPE will be the highest, but the MRGL risk area will cover practically the entire rest of Eastern PA. An upper level trough passage favors one final round of showers and storms on Friday, but fortunately the Labor Day weekend is trending dry. The upper ridge is forecast to retrograde by the end of the week which allows for a return to more seasonal temperatures and lower humidity this weekend into early next week. &&

Strong to severe thunderstorms with damaging winds and heavy rainfall are expected once again today through early tonight.

US National Weather Service State College PA As the overnight's storms push to the southeast, another round is beginning to move in from the northwest. The environment doesn't look very supportive, so this is anticipated to weaken as it pushes southeast. All hazards threat for activity later in the afternoon/evening

Who could sleep through what I experienced during the night? Continuous lightning for hours, thunder and heavy rain at times. Almost 2" fell since 11:45pm.

Good lightning show to my north.

Let's see if it come to fruition.

Wow 3 days in a row of possible severe weather.

With that last sentence, you'll definitely awaken the great Blizz. It's way to early to awaken him. You'll need to start the fall thread in a few days.

Theres still some heat and humidity to be had before we close the book on summer. Fall is getting close, and for some of us...it's too close.
