The episode as NWS CTP wrote it up.
A couple of rounds of severe weather affected central Pennsylvania on June 5, 2016. The first was a line of convection that pushed across the Lower Susquehanna Valley during the late afternoon hours, producing sporadic wind damage across Adams, York and Lancaster counties. The second round developed along a lake-enhanced outflow boundary and affected northwestern Pennsylvania during the early evening hours, producing wind damage across Warren, McKean and Elk counties and generating an EF-1 tornado in Warren County.
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 State College, PA wrote its last area forecast discussion before the first event at Jun 5, 2:18 PM EST, 16 minutes earlier.
Area Forecast Discussion National Weather Service State College PA 318 PM EDT SUN JUN 5 2016 .SYNOPSIS... A cold front moving east through the Ohio Valley will push a plume of deep moisture northward into into the state today as a warm front also lifts north across the region. Numerous showers and thunderstorms...some severe...will move across the state during the reminder of the afternoon and early evening hours. Warm...mainly dry...and much less humid air will move in for Monday. Another cold front will move southeast from the Great Lakes on Tuesday bringing another round of unsettled conditions for Tuesday into early Wednesday. Cooler and mainly dry weather will follow for later in the week. && .NEAR TERM /UNTIL 6 PM THIS EVENING/... *Scattered to numerous severe thunderstorms remain possible over the eastern 1/2 of Pennsylvania today. *Will need to watch Nwrn PA for psbls severe storms later this aftn and early evening as secondary line develops Severe Thundestorm Watch #236 now in effect for Lower Susq River Valley until 10 PM EDT. A shortwave trough moving up the Ohio River Valley this morning will assume a negative tilt as it moves northeastward across the Mid Atlantic region this afternoon/early evening. At the surface, low pressure will deepen to below 1000mb lifting northward across the lower Great Lakes into southern Ontario. A SW-NE plume of deep tropical moisture with PWATS of 1.5-2 inches will reside across much of the forecast area through today...as one or more mid-upper level jetlets cross the state. Enhanced upper level divergence in the favorable L.E. and R.E. regions of the jet maxes after 15z will team up with peak heating and instability...along with a A wind shift line/surface trough (that will extend southward from the low and move across central PA during the afternoon and evening hours today)...helping to focus one or more bkn lines of strong to severe tsra. The clouds/precipitation early today still could be a limiting factor for severe wx. Assuming this does not occur and boundary layer destabilization can be realized, rapidly strengthening vertical wind shear profiles and increasing speed shear aloft are favorable for organized severe storm clusters including a few supercells. The main emphasis is that scattered to numerous severe thunderstorms are possible across portions of central and southeast PA Sunday afternoon and evening with hail, damaging winds and a few tornadoes possible. && .SHORT TERM /6 PM THIS EVENING THROUGH 6 PM MONDAY/... latest radar imagery shows narrow line of intense rainfall stretched ne to sw acros central pa along leading edge of area of moderate to heavy rain...preceding approaching cold front/upper trof. visible satellite imagery and sfc obs continue to show sig cloud cover in warm sector ahead of ongoing pcpn. clouds are limiting sfc warming which in turn is likely prevnting further intensification of current cells and formation of new convection within the warm sector. spc has recently issued swomcd for sern pa and swd into nova...but yet to be seen if severe convection will be able to pop. The primary llj...larger scale forcing and the sfc trough pushes quickly east of the susq valley by dusk...leaving just isolated showers and some clearing across the CWA. A trailing and weakening cold front will push across western and central PA during the evening hours...then through the Susq Valley later tonight...bringing the chc for a few more showers within an axis of still moderately high pwats of 1.25 to 1.5 inches. Well after midnight...expect partial clearing and showers should greatly decrease in coverage with cooler and drier air advecting into the commonwealth and PWATS decreasing by approx 0.50 of an inch. Low temps at sunrise Monday should be in the mid 50s to mid 60s (or about 8 deg lower than those early Sunday). Weak surface ridging across the region monday will provide some morning sunshine with sw flow at the surface and aloft. cooling mid and upper levels in the afternoon and the approach of a weak cfront will spark some scattered showers and even a few isolated low-topped tsra across the wrn mtns. Locations SE of the allegheny front should see at most a few isolated showers after 18z monday. high temps Monday will be near to slightly above normal...but with much more comfortable dewpoints in the 50s. && .LONG TERM /MONDAY NIGHT THROUGH SUNDAY/... *Cooler and unsettled pattern for tuesday and Wednesday June 7-8th *Improving conditions with gradual warming trend likely by next weekend By early in the upcoming week, broad cyclonic flow beneath an anomalous eastern U.S. trough will keep an unsettled pattern in place into the middle of next week. Multiple pieces of energy embedded within the mean trough aloft may generate one or more periods of showers and possible afternoon thunderstorms - given strong diurnal component and relatively cool air aloft. High pressure builds into the area during the second half of next week likely bringing improving conditions. Additional pieces of energy aloft may bring more chances of showers late in the week. Near- to- below normal temperatures during the first half of next should gradually trend warmer by next weekend. && .AVIATION /19Z SUNDAY THROUGH FRIDAY/... latest radar imagery shows narrow line of intense rainfall stretched ne to sw across central pa along leading edge of area of moderate to heavy rain...preceding approaching cold front/upper trof. visible satellite imagery and sfc obs continue to show sig cloud cover in warm sector ahead of ongoing pcpn. clouds are limiting sfc warming which in turn is likely prevnting further intensification of current cells and formation of new convection within the warm sector. widespread mvfr with embedded ifr accompany the line of rain. elsewhere vfr conds are expected. By 00Z Mon most of the storms will be off to the east of the terminals. Expect another round of IFR cigs and vsbys at all terminals overnight into Monday morning, especially in areas that received precipitation. OUTLOOK...
