A weak disturbance moved through Northeastern Pennsylvania during the afternoon. The environment was unstable enough to support some severe thunderstorms that produced damaging wind gusts and large hail.

NWS Binghamton, NY wrote its last area forecast discussion before the first event at Jul 22, 1:15 PM EST, 31 minutes earlier.
Area Forecast Discussion National Weather Service Binghamton NY 215 PM EDT Fri Jul 22 2022 .SYNOPSIS... Isolated to scattered thunderstorms are developing this afternoon mainly in south central NY and northeast PA. A couple of the stronger storms could contain small hail and isolated damaging wind gusts. Saturday into Sunday, the heat returns with highs in the upper 80s to low 90s and heat index values approaching the mid to upper 90s. && .NEAR TERM /THROUGH SATURDAY NIGHT/... 1230 pm update... The radar is back. The better moisture with the dying showers earlier has now moved into the eastern counties. This has helped showers, some with heavy rain, to form. The cap is gone everywhere. Limiting factors will be mid level lapse rates, wind shear for now, and lack of deep moisture. Minor changes. 820 am update... Added chance pops for Steuben county this morning as a dying cluster of showers slowly moves east. Otherwise minor changes. Showers and thunderstorms are still expected to form starting midday. 615 AM Update... Small changes to the temperatures as valleys radiated out to a few degrees lower than the forecast lows. PoPs have not been adjusted yet but watching a persistent cluster of showers and thunderstorms moving through NW PA. If this can hold together then NEPA may get some mid to late morning rain and the clouds could limit heating and instability limiting our thunderstorm potential this afternoon. 320 AM Update... Clear skies this evening has allowed for lows to fall to about 10 degrees colder than where they were yesterday at this time. Temperatures rise back into the upper 80s to low 90s this afternoon. Todays temperatures were bumped up a couple of degrees due to the dry soils and it is looking like lower dew points will mix down once again this afternoon. The lower dew points keeps heat indexes below heat advisory criteria but urban areas could get close. A weak 500 mb shortwave moves through this afternoon and with around 1000 to 1500 J/kg of surface based cape and around 30 knots of bulk shear. The 0-1 and 0-3 km shear is below 15 knots so most of the shear is elevated. Low level lapse rates are going to be steep with the dry soils and deep mixing this afternoon. A couple of storms could develop elevated cores if they get tall enough with damaging wind gust possible as the cores descend so a marginal risk has been issued by SPC for most of our CWA. Given that the shortwave is passing through in the afternoon and not as much dry air aloft relative to yesterday there is a little higher confidence that there will be at least a couple of stronger storms in the Twin Tiers region this afternoon into the early evening. Tonight will be another clear night with good radiational cooling. Fog is likely wherever it rains. Valley fog will still have a good chance of developing in the typical valley spots in the upper Susquehanna river basin with the higher boundary layer moisture tomorrow afternoon and evening. Saturday is shaping up to be another hot day. Dew points will likely be a few degrees higher than today and high temperatures also a degree or two higher. Heat indexes will likely stay below advisory criteria once again. A few pockets of slight chance of thunderstorms were added to the grids in higher elevations of Steuben county into the Finger Lakes region since there will be some weakly capped instability and a terrain induced thunderstorm would be possible in the late afternoon. && .SHORT TERM /SUNDAY THROUGH MONDAY/... 215 PM update... Main concerns in the short term are focused on the hot and humid conditions expected Sunday...and the showers and thunderstorms expected to push through the region late Sunday and into Monday with slightly cooler temperatures. A surface low will be lifting to the east/northeast from the central Great Lakes into Quebec on Sunday with a trailing cold front sweeping eastward into the Northeast and northern Mid Atlantic region. Ahead of this cold front a very warm and humid air mass is expected to develop and produce temperatures into the 90s for much of central NY and ne PA. The warmest air will be felt throughout the valleys and across the lake plain of the northern Finger Lakes where mid to upper 90s are possible. Surface dew points are expected to rise into the mid to upper 60s in the morning hours, and then as the boundary layer deepens through the afternoon, mix out into the lower to mid 60s during the peak heating of the day. Corresponding heat index values will top out in the mid 90s to around 100. Heat Advisories will likely be needed on Sunday. The environment will be quite unstable by the afternoon with ML CAPE values 1000-2000 J/kg and steep low level lapse rates. Deep layer shear will be on the rise through the day as the upper trough and surface cold front approach from the west. There is a marginal threat for severe thunderstorms on Sunday given the unstable air mass, deep shear, broad large scale lift, and sufficient moisture all overlapping over the eastern Great Lakes. The timing of the front/upper trough and the amount of inhibition from morning clouds, along with relatively shallow mid level lapse rates may hinder the potential for deep convection leading to severe storms. There is expected to be a swath of rain with this incoming cold front late Sunday into Monday. Some areas could see a decent amount of rain. The initial push of rain may come as more scattered convection, but the second round of showers and embedded weak storms late Sunday into Monday may arrive in the form of more stratiform/steady rain. A corridor of deep moisture will phase with an axis of warm air advection and isentropic lift that should induce a more steady widespread rainfall. Amounts will range from from a half to 1.25 inches. A few isolated locations could see 1.5 to 2 inches by sunset Monday. Most areas are running 1-3 inches below normal for the past 30 days, so hopefully this rain will provide some needed relief. The presence of clouds and rain on Monday will keep temperatures in the upper 70s to mid 80s. && .LONG TERM /MONDAY NIGHT THROUGH THURSDAY/... 215 PM update A few lingering showers and weak storms may be hanging around parts of the Poconos and southern Catskills Monday night, but by late Tuesday morning most of the region will be clear of precipitation. Dry air will start to advect in from the west on Tuesday which will act to scatter out most of the clouds. A flat ridge pattern takes shape and continues into early Wednesday with quiet weather expected and temperatures gradually warming back into the mid to upper 80s on Wednesday after seeing some upper 70s and lower 80s on Tuesday. A weakly amplified upper short wave will approach from the west late Wednesday and Thursday, and act to trigger the next round of showers and storms. && .AVIATION /18Z FRIDAY THROUGH WEDNESDAY/... 130 pm Update... Mostly VFR through 18z Saturday. Showers and thunderstorms have formed but the coverage will be isolated. Have a tempo for showers at AVP 21 to 24z. Sites in south central NY will probably have one or two showers but restrictions not expected. Late tonight valley fog will form. ELM could have restrictions between 08 to 12z, especially if it rains towards sunset. Saturday isolated showers possible again after 17z. Southwest to west winds at 5 to 10 kts into the evening. Tonight winds light and variable to calm. Saturday southwest winds will be 5 to 10 kts again. Outlook... Saturday afternoon through Sunday morning...Mainly VFR; slight chance for showers and thunderstorms for NY terminals starting Saturday afternoon. Sunday afternoon through Monday...Possible restrictions in showers and thunderstorms. Most likely time Sunday afternoon and evening. Monday night through Wednesday...mainly VFR. Possible valley fog at ELM. && .BGM WATCHES/WARNINGS/ADVISORIES... PA...None. NY...None. && SYNOPSIS...AJG/TAC NEAR TERM...AJG/TAC SHORT TERM...BJT LONG TERM...BJT AVIATION...TAC
