The episode as NWS PBZ wrote it up.
A very moist airmass and a nearly stationary front resulted in rounds of thunderstorms that produced flash flooding on June 6th. This included reports of flooding in Noble county, Ohio.
The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Pittsburgh, PA wrote its last area forecast discussion before the first event at Jun 6, 9:46 AM EST, 3 hours 8 minutes earlier.
Area Forecast Discussion National Weather Service Pittsburgh PA 1046 AM EDT Fri Jun 6 2025 .SYNOPSIS... A stationary front will remain across the region today and tonight, and will provide the focus for periodic showers and thunderstorms. Some storms could be severe and could contain locally heavy rain this afternoon and evening. The front will drift south Saturday, with shower and storm chances diminishing. Unsettled weather is then expected Sunday through Tuesday with a series of crossing disturbances. && .NEAR TERM /UNTIL 6 PM THIS EVENING/... KEY MESSAGES: - Additional rounds of showers and thunderstorms today - Marginal Risk for severe storms this afternoon - Locally heavy rainfall possible --------------------------------------------------------------- Updated to refresh near-term grids based on radar/ob trends. Subtle shortwave/vort max was responsible for morning thunderstorms that produced locally heavy rainfall in portions of eastern Ohio and southwest PA. Morning sounding measured 1.68 inch precipitable water values, which is near the climatologic maximum for early June, highlighting the ongoing heavy rainfall threat. The marginal (level 1 out of 5) risk for damaging wind gusts remains. Downdraft CAPE will be less favorable today, but a bit deep-layer shear will be present, which will allow for storm organization and some isolated damaging gusts. Previous discussion... A stationary front was analyzed across northern Ohio into NW PA. This front will remain quasi stationary today with the flow aloft parallel to the front. Individual vort maxes embedded in the westerly flow aloft will provide additional ascent for showers and thunderstorms today. One shortwave is expected to cross the area this morning, bringing an increase in showers and a few storms. These showers and isolated thunderstorms have recently developed across Ohio as this wave approaches. A surface wave is expected to develop along the front this afternoon, as it tracks across the Upper Ohio Valley region. This should bring another increase in showers and thunderstorms. Building diurnal instability is progged through the day, with mean MU CAPE values ranging from 1000-1500 j/kg. An increase in the mid and upper level flow should result in more shear than yesterday, with 0-6km values from 30-40kt. This could result in a few organized storms across the region, with a damaging wind potential. The Storm Prediction Center has included most of the area in a Marginal Risk, or level 1 out of 5, for severe storms this afternoon and early evening. PWATS remain elevated at around 1.5 inches. Locally heavy rainfall is possible, though storm motion should be faster than today. Still, if any area receives multiple storms, localized flash flooding will be possible. Will include this potential in the Hazardous Weather Outlook and add a mention of locally heavy rain to the forecast grids. The threat appears to be too localized for a flash flood watch at this time. && .SHORT TERM /6 PM THIS EVENING THROUGH SUNDAY NIGHT/... KEY MESSAGES: - Marginal Risk for severe storms early this evening - Locally heavy rainfall possible especially this evening - Decreased rain chances Saturday - Increasing showers/storms Sunday ---------------------------------------------------------------- The surface wave will continue to track east along the front early this evening. Showers and thunderstorms will continue, along with a marginal potential for damaging wind gusts and locally heavy rain. MU CAPE quickly diminishes this evening after the passage of the surface wave. Expect the severe weather potential to end early this evening with the loss of surface based instability, though elevated instability could still support a few storms overnight. Another crossing shortwave trough is progged for a Friday night passage, with showers and a few thunderstorms continuing. The resulting WNW flow behind this trough should help to push the front south of the region on Saturday. Expect an overall decrease in POPS from N-S, with most areas from PIT northward staying dry. Areas to the south will still be in closer proximity to the front, with shower and isolated thunderstorm chances continuing. Saturday evening should be dry with the front to our south. Another shortwave trough is expected to advance out of the Midwest Saturday night, along with a developing surface low. The trough will cross th Upper Ohio Valley region on Sunday, as the surface low tracks across the Great Lakes, pulling the front back north as a warm front. Increasing shower and thunderstorm chances are expected again during the day with the approach and passage of the shortwave trough and warm front. There is also a potential for severe storms Sunday with increasing shear and instability, though details will be monitored over the next couple of days. The front should lift north of the region Sunday night, as the shortwave trough exits. Expect showers and thunderstorms to taper off Sunday evening, and end overnight. && .LONG TERM /MONDAY THROUGH THURSDAY/... KEY MESSAGES: - Unsettled weather Tuesday - Dry and less humid weather returns Wednesday and Thursday ------------------------------------------------------------------- Model ensembles indicate a deep trough across the Upper Midwest on Monday, advancing eastward through the day. Expect shower and thunderstorm chances to increase again Monday with moisture and ascent overspreading the region in SW flow ahead of the trough. The highest shower and thunderstorm chances are expected on Tuesday, as the trough axis crosses the region. The trough is expected to exit the region on Wednesday, as surface high pressure begins to build in. This should return dry weather to the region Wednesday and Thursday. Temperatures should average near seasonable levels through midweek, before rising 500 mb heights and a building ridge return readings to above average by Thursday. && .AVIATION /15Z FRIDAY THROUGH TUESDAY/... First wave of showers and isolated thunderstorms is crossing the area this morning. Cigs have and will continue to quickly lower into MVFR/IFR except south and east of PIT (MGW/LBE). Showers will become spottier again by midday with gradual cig improvement. Scattered showers and thunderstorms are likely after 18z today as convective temperatures are reached. Covered this threat with PROB30s given scattered nature of potential thunderstorms. Lingering showers/storms will diminish near 00z as cigs lower into IFR areawide. Restrictions will overnight continue through much of Saturday morning. Outlook... Widespread MVFR/IFR ceiling restrictions are expected into Saturday as a series of shortwaves brings continued shower and thunderstorm chances. These are likely to lift Saturday afternoon with brief drying. Crossing low pressure will renew restriction potential with rain on Sunday, with additional waves of rain expected Monday into Tuesday. && .PBZ WATCHES/WARNINGS/ADVISORIES... PA...None. OH...None.
