A low pressure system with a warm front pushed through Central New York, providing support for isolated storms. While instability was limited, there was enough to support one lone severe storm that knocked down a few trees in Steuben County.

NWS Binghamton, NY wrote its last area forecast discussion before the first event at Jul 17, 6:43 PM EST, 26 minutes earlier.
Area Forecast Discussion National Weather Service Binghamton NY 743 PM EDT Sun Jul 17 2022 .SYNOPSIS... A developing warm front will lift north through the area tonight, bringing periods of showers and thunderstorms to the region, especially over the Finger Lakes. Some breaks of sun are expected to develop Monday, setting the stage for additional rounds of showers and thunderstorms Monday afternoon, as a cold front sweeps through the area. Some storms may be severe, especially east of I-81. Another cold front looks to pass through the area Thursday, bringing another chance for needed rainfall. && .NEAR TERM /THROUGH MONDAY/... 318 PM Update... A fairly strong upper level trough over the Midwest, with several embedded shortwave troughs, will move into the lower Great Lakes through Monday. An attendant surface low is slowly developing over NW Indiana, and it will deepen as it moves ENE towards Buffalo by Monday afternoon. Ahead of the low, a warm front is taking shape to our south, and will lift north towards the Mohawk Valley by midday Monday, while a cold front moves into western PA, eventually sweeping across the region Monday afternoon and evening. A line of convective showers and a few thunderstorms is already trying to take shape roughly along the warm front, arcing across far SW NY into central PA. This is likely being aided by a lead shortwave trough and a favorable jet position. Expect this band of showers and thunderstorms to slowly move northeast towards the Finger Lakes region and Bradford County PA later this afternoon and into the evening hours, though it is expected to diminish in intensity as it moves further to the northeast. Additional bands of precip, with some embedded thunder, will redevelop to our SW and spread northeast later tonight, especially after midnight as a low level jet gets cranking over western PA and NY. The heaviest rainfall totals through morning looks to be most focused on the areas west of I-81, though perhaps not as far west as the 12Z NAM suggests. The NAM is a little too fast in deepening the surface low and results in a a more backed LLJ orientation that's a little too far to the west. So while western areas are likely to see the best QPF through the morning hours, with lesser amounts in the Catskills and Poconos, don't expect the contrast to be quite so sharp as the NAM indicates. Steadier precip will drift north of the area Monday morning, with some breaks in the cloud cover expected to develop in the warm sector, especially near and east of I-81. Just how much clearing occurs will be critical in determining the amount of instability that can build up ahead of the cold front. Should the NAM's stronger surface low scenario pan out, greater instability and stronger low level shear would be realized, enhancing the threat of severe thunderstorms during the afternoon. However, even with the NAM, mid-level lapse rates are not terribly steep, which is a limiting factor that likely precluded an upgrade to the SPC Day 2 outlook. The best chance for severe thunderstorms is likely to be in a more narrow corridor east of I-81 tomorrow, but this will need to be closely watched, especially considering the rather mundane weather of late. Localized heavy rainfall will also be possible with the afternoon round of thunderstorms, but this will mainly be focused over the areas that receive the lesser precip amounts tonight (Cats/Pocos). Coupled with the dry antecedent conditions, the risk of flooding is low outside a few highly localized "unlucky" areas where training cells can develop. && .SHORT TERM /MONDAY NIGHT THROUGH WEDNESDAY/... 235 PM Update... The upper level feature trailing behind Monday's low pressure system will be just about east of the region by daybreak Tuesday. There are very low chance PoPs for lingering showers across the Western Mohawk Valley area before 8 AM...and then we have dropped everything back to a mainly dry rest of the morning. Some diurnal instability regenerating during the afternoon may get tapped by the lake breeze or terrain for a chance of thunderstorms and have maintained isolated PoPs across the north. The remainder of our area seems to have a bit stronger of a cap being closer to a ridge of high pressure. Wednesday looks to be in between systems with a broad ridge across the Northeast and a modest mid-Summer low cutting through the Upper Lakes. Much of the day is likely to be dry and warm with perhaps the first hints of showers and thunderstorms developing over the Finger Lakes during the late afternoon as upper heights fall and instability peaks. Lake boundaries possibly come into play as a surface focus from Syracuse westward. Quite warm each of these days with highs at, or above normal from the mid-upper 80s and low 90s. && .LONG TERM /WEDNESDAY NIGHT THROUGH SUNDAY/... 235 PM Update... Ensemble guidance suggests slightly anomalous warmth for this period, but not seeing any classic heat waves on the horizon... so temperatures are looking to be at or a little above normal from the mid 80s to around 90 in the usual hotter spots during most of this period. Thursday looks to be reasonably active with a pre-frontal trof over the region in the morning, followed by a cold frontal passage during the afternoon. Instability parameters seem to only rebound for our eastern and southeastern zones from midday into the afternoon where we would have to focus our attention most for severe weather or heavy rain potential. Friday and Friday night we look to be between systems with weak high pressure keeping much of the time rain free. On Saturday, there appears to be no significant triggering mechanism, but there is a chance for weak upper waves passing through which introduces low chance PoPs again as we will be just south of a stationary front with increasing instability parameters. Sunday is highly uncertain with diverging models. All the globals do suggest stronger height falls ahead of a sharper 500 mb wave dropping through the Upper Lakes and there are varying amounts of QPF being kicked out by the guidance during the afternoon. Surface fronts aren't really in the picture being to our north and west, but I think it's safe to include another round of PoPs out ahead of this approaching upper level feature. && .AVIATION /00Z MONDAY THROUGH FRIDAY/... VFR continues for most terminals through the remainder of the evening, though a batch of slowly moving showers and storms may bring some restrictions into ELM within the next hour. This initial batch may also impact AVP and ITH before 06Z, then more widespread showers start to move in to all terminals. Ceilings area-wide lower as this next round of rain moves in, then MVFR restrictions finally settle in between 08-12Z for all TAF sites except for KRME and KSYR which would have later timing. Steadier, heavier rain into the pre- dawn hours and increasing moist, low level flow will allow ceilings to drop further after 09Z. Ceilings approach IFR towards dawn across the Southern Tier of NY and perhaps even at AVP as winds shift more to the south and southwest. After the batch of morning rain, most of the area should see a brief dry period while ceilings lift slightly, then another batch of showers and thunderstorms is expected for the afternoon and evening. Strong storms with gusty winds are possible, with MVFR/fuel alternate restrictions expected. Outlook... Monday Night...Showers and thunderstorms with associated restrictions linger the first half of the night, then gradual improvement as storms move out. Tuesday through Thursday...Mainly VFR; low chance for showers and thunderstorms and associated restrictions for NY terminals. Friday...Mainly VFR. && .BGM WATCHES/WARNINGS/ADVISORIES... PA...None.
