I think I've seen a month's worth of rain the past few days.

It's crazy how much variance there is in these storms though. I only got about .75 in yesterday and didn't get anything the previous days. Today it have rained about .1 in here.

Mesoscale Discussion 1131
   NWS Storm Prediction Center Norman OK
   1215 PM CDT Fri Jun 23 2017

   Areas affected...Northern KY...Southern/eastern OH...Western
   WV...Western PA

   Concerning...Severe potential...Watch possible 

   Valid 231715Z - 231915Z

   Probability of Watch Issuance...40 percent

   SUMMARY...A gradual increase in the threat for damaging wind gusts
   and perhaps a tornado or two is expected this afternoon. Watch
   issuance is possible.

   DISCUSSION...A gradual increase in the intensity and coverage of
   convection has been noted across portions of southern OH, in advance
   of a large precipitation shield (with embedded convection) further
   to the northwest. While midlevel lapse rates are poor, given the
   influence of the decaying tropical system to the southwest, modest
   heating within a very moist environment has resulted in moderate
   destabilization, with SBCAPE rising into the 1000-1500 J/kg range
   where temperatures have warmed into the low 80s F. Further
   intensification is possible, both with the more discrete activity
   across southern OH and northern KY, and within the larger convective
   plume across central/northern OH as that moves eastward. 

   With strong deep-layer southwesterly flow over the region, effective
   shear has increased into the 40-50 kt range, which is more than
   sufficient for some organized storm structures. With unidirectional
   wind profiles in place, damaging wind gusts are expected to the
   primary threat, though low-level shear is sufficient for a tornado
   or two with any semi-discrete supercells that can evolve. Watch
   issuance is possible later this afternoon to cover this threat.

Looks like there might be a weak area of rotation just to my south.  No warning from PBZ, though.  But they are the experts.

Just missed tornado here-there was one spotted by trained spotter about 7 miles northwest....didn't even really get windy

We got zero wind here.  I followed the tornado warning in Greene County for a little, but it lost much of its organization through the latter half of the county.  Evidently a funnel was spotted at one point in Pine Creek, but I never saw a funnel myself.  Pretty loose rotation, if any.

Yea there wasn't any damage reported that I saw-just a small funnel cloud reported....kind of uneventful to be honest-not even windy really just heavy heavy rain

A trained spotter claimed there was a rope tornado on the ground south of Uniontown.  I still haven't come across any videos/pictures.  

EF1 tornado was confirmed in Washington County.

Nights like tonight make me think our local nws office is just flat out lazy. Up until about an hour ago my point in click in the north hills gave a 20% chance of rain. I had been checking the radar, and since 8 or 9 it was blatantly obvious these storms were going to push at the very least into the northern half of the county. 

 

Now, when it starts to rain, they upped my POPS to 100%. Thanks guys, I couldn't see the lightning or hear the downpour outside!

It seriously was like they didn't want to update the forecast.

 Mesoscale Discussion 1276
   NWS Storm Prediction Center Norman OK
   0208 PM CDT Mon Jul 10 2017

   Areas affected...Southeast OH...Southwest PA...and Northern WV

   Concerning...Severe potential...Watch possible 

   Valid 101908Z - 102115Z

   Probability of Watch Issuance...40 percent

   SUMMARY...Scattered strong and occasionally severe storms will
   affect parts of southeast OH, southwest PA, and northern WV this
   afternoon.  This area will be monitored for a possible watch if
   trends warrant.

   DISCUSSION...A long-lived MCV (remnant from overnight convection) is
   moving eastward across western OH.  The air mass ahead of this
   feature is only slowly destabilizing due to extensive cloud cover
   and scattered precipitation.  However, partly cloudy skies in the
   southeast flank of the MCV over southeast OH are helping
   temperatures to warm through the 70s with near 70F dewpoints.  While
   low-level lapse rates are somewhat limited today, low-level wind
   fields are relatively strong as depicted by ILN VWP data.  Continued
   heating will likely lead to scattered thunderstorm development, with
   sufficient vertical shear for a few organized/bowing convective
   segments.  Sufficient CAPE may also promote a risk of hail in the
   strongest cells.  Convective trends will be monitored in this region
   for the possibility of a watch if bowing structures becomes
   evident/more likely.

Mesoscale Discussion 1364
   NWS Storm Prediction Center Norman OK
   0250 PM CDT Thu Jul 20 2017

   Areas affected...Eastern/southern OH...western/central PA...northern
   WV

   Concerning...Severe potential...Watch unlikely 

   Valid 201950Z - 202215Z

   Probability of Watch Issuance...20 percent

   SUMMARY...Isolated damaging-wind potential could accompany
   thunderstorms moving across portions of the middle and upper Ohio
   Valley region to the central Appalachians and vicinity into the
   early evening hours. Watch issuance is presently unlikely.

   DISCUSSION...Thunderstorm development continues along a diffuse cold
   front from northwest PA through north-central OH. Additional storm
   development may also focus along the northern and eastern periphery
   of a residual MCV presently moving across southwest OH. MCV-related
   ascent is being augmented by differential-heating-induced baroclinic
   circulations along fringes of multi-layered cloud decks surrounding
   the MCV. The air mass south of the front and ahead of the MCV has
   become moderately unstable, owing to surface temperatures having
   warmed through the 80s amid dewpoints in the upper 60s to around
   70F. The most intense storms may produce locally damaging wind 
   gusts -- aided by slightly enhanced deep shear (around 20-40 kt of
   effective shear). 

   However, stronger deep shear resides north of this region, which
   should limit overall convective organization. Moreover, poor
   mid-level lapse rates, veered low-level flow ahead of the front
   limiting frontal convergence, and modest background low-level flow
   strength should prevent a more substantial severe risk from
   occurring.
