Unstable conditions supported scattered showers and thunderstorms. A stronger storm passed through southern Broome County in Central New York and knocked down a tree onto a roadway just south of Binghamton. Small hail was also reported with storms this day.
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 Binghamton, NY wrote its last area forecast discussion before the first event at Aug 5, 1:38 PM EST, 3 hours 18 minutes earlier.
Area Forecast Discussion National Weather Service Binghamton NY 238 PM EDT Fri Aug 5 2022 .SYNOPSIS... Unsettled, very warm summer weather pattern will persist across the region through the weekend and early next week. There will be chances for showers and thunderstorms each day, especially in the afternoon and evening hours. Some storms may produce locally heavy rainfall. Temperatures will be well above average over the weekend and on Monday along with high humidity. && .NEAR TERM /THROUGH SATURDAY/... Thunderstorms have started to fire across the western Finger Lakes and Lackawanna county in NEPA, where clear skies have been present for the past few hours. Storms are expected to continue to fire across CNY as clouds dissipate and surface temperatures rise. These are slow moving, pulse type storms that are small but numerous cells are developing. The lack of a steering flow is causing a lot of back building and divergent motions as these storms reach full strength and dissipate. Flash Flooding will be possible across areas that receive heavy rain, backbuilding storms, and were impacted by heavy rains from yesterdays storms. Antecedent conditions have been dry across the region so the soils and rivers can handle heavy downpours. Widespread flash flooding is not expected, but localized flooding across areas that are prone to flooding or have backbuilding storms will be possible. Storm development is expected to be diurnal and dissipate by the evening. Overnight, light winds, moist soils and high pressure over the area will allow for valley fog to form. SW flow aloft continues through the overnight hours, keeping conditions warm and humid. Muggy lows in the mid to upper 60s are expected. Saturday will be hot as SW flow and high pressure overhead bring temperatures into the mid 80s to low 90s. With afternoon dewpoints in the upper 60s to low 70s, heat index values will approach 95, especially in the valleys. Another round of scattered afternoon thunderstorms is expected. Steering flow will again be light so storms will be slow moving with the chance to produce heavy downpours. && .SHORT TERM /SATURDAY NIGHT THROUGH SUNDAY NIGHT/... 140 PM Update... Minimal changes made to the Sunday Forecast. Heat, humidity and afternoon thunderstorms still expected. Ingredients for heavy rainfall rates will continue with PWATs staying above near or above 1.75", short Corfidi Vectors and overall weak flow that will be parallel to stationary front draped over the region. All these ingredients bring potential for localized flash flooding, especially in flashy/poor drainage areas. 330 AM Update... High pressure remains in control Saturday night and Sunday with weak warm air advection providing the forcing for scattered showers and thunderstorms. I dont anticipate a washout but we have a medium chance (40%) of afternoon thunderstorms on Sunday. With the warm air advection in place and little in the way of regime change anticipate temperatures to be on the warmer side. Ensemble guidance is tightly packed in the low to mid 90s for ELM/BGM/AVP. There about a 10% chance of temps reaching the upper 90s Sunday, however I think as soon as temps get into the upper 80s to low 90s we'll see convection quickly developing and rain showers will minimize how hot the region could actually warm to. Notably the EC EFI is keying on abnormally warm temperatures both day and night through the weekend and into Monday which adds confidence in the forecast of temperatures well above our climo normals of the low 80s for early August. The combination of those high temperatures and a moist airmass leads to a forecast of heat index values in the range of the mid to upper 90s. Given the lack of upper level forcing, shear will remain weak throughout the period. This will allow for the showers that develop to be slow moving with a chance for back building. Current PWATs look marginal and are between 1.5 to 1.75 standardized anomalies above normal based on the NAEFS, lending to periods of heavy rainfall. && .LONG TERM /MONDAY THROUGH THURSDAY/... 140 PM Update... Potential for heat/humidity and thunderstorms will continue through the first half of the work week. Made very little changes to the overall forecast. Models are advertising a pattern change by the middle to end of next week, as a cold front pushes through and dry/cool Canadian High Pressure replaces the tropical-like airmass in-place. 330 AM Update... A cold front associated with an upper level trough looks to eventually finally swing through the region early in the work week. High pressure will generally start to retreat and the front will pass through leading to more organized convective activity. The question will be how soon does it make it into the region. Warm air advection will be pumping into the region with high temps running into the low to mid 90s again Monday. Ensemble spread is higher on Monday however the means are still right in the same range as Sunday. At this point we've continued the upward trend in forecast temps and this will once again push the region into heat advisory criteria with much of the valleys seeing heat index values in the upper 90s. Folks who are sensitive to heat should be making plans for this weekend to seek relief from the heat and staying hydrated. In addition to the heat, flash flooding may possible for this event, given the elevated PWATs ahead of the front and rain that is expected to fall this weekend, priming the soil for a better chance of flooding if heavy rains occur. Ensemble guidance is showing the various potential speeds of the frontal system with a large amount of spread in temperature guidance. The spread between the coldest member and warmest member is on the order of 20 degrees for max temps on Tuesday. So I've opted to stick with the mean of upper 70s to low 80s until the timing of the front moves into better agreement. Behind the front, high pressure will build into the area, bringing NW flow and cool, dry Canadian air to the region through the end of the week. Highs Wednesday and Thursday will be in the mid 70s to low 80s with lows getting into the 50s. && .AVIATION /18Z FRIDAY THROUGH WEDNESDAY/... Thunderstorms have started to fire across the area. ELM and AVP are the closest terminals to the areas with the best chance for storms this afternoon. Because of the slow, heavy rain nature of these storms, tempo IFR visibility was brought into the TAFs for these terminals as storms currently near these sites have produced IFR conditions. BGM and ITH should start to see storms move into the area over the next couple hours, but because these are random, pulse type storms, confidence was not high enough to drop conditions here to IFR. MVFR ceilings and visibility were introduced into the TAFs for this afternoon, but IFR conditions could occur if a storm develops over the terminal. SYR and RME should also see storms this afternoon, but confidence is low on timing of these storms. The greater development is south of the Mohawk Valley, but isolated storms could roll through early this afternoon or develop later this afternoon along outflow boundaries from other storms. Because current ceilings have been near MVFR early this afternoon, I was confident enough to include MVFR conditions in the TAFs if storms form. Overnight, fog is expected to form again in the valleys as high pressure is overhead, winds will be light and the ground very wet from the last 2 days of rain. Highest confidence for for is at ELM, with LIFR visibilities expected again overnight. Guidance is showing hints of fog and restrictions reaching BGM/ITH/RME but confidence is too low to include it in this TAF set. Outlook... Saturday afternoon through Monday Morning...VFR much of the time yet with isolated to scattered showers and thunderstorms, and associated brief restrictions, especially afternoons. Restrictive valley fog also possible early each morning at KELM. Monday afternoon through Tuesday...Passing frontal system may bring a more organized likelihood of showers and thunderstorms with restrictions, eventually involving most or all terminals. && .BGM WATCHES/WARNINGS/ADVISORIES...
