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 Jul 24, 5:53 AM EST, 4 hours 9 minutes earlier.
Area Forecast Discussion National Weather Service Binghamton NY 653 AM EDT Mon Jul 24 2023 .SYNOPSIS... High pressure looks to be dominant over the region must of this week. However, a few weak disturbances look to trigger a few showers and thunderstorms most days. A cold front then looks to move southeast through the area later this week. && .NEAR TERM /THROUGH TUESDAY/... The previously mentioned cluster of showers and thunderstorms has tracked north into the Southern Tier associated with a weak vort maximum. Increased coverage of showers and thunderstorms through mid-morning to account for this. These storms have also been borderline strong with indicators of pea size hail and marginal wind gusts. Previous... Heading toward sunrise, we are tracking a cluster of showers and thunderstorms northwest of State College tracking toward Steuben county and portions of the Twin Tiers. Will indicate a low chance for this activity moving in through the remainder of the overnight. With the initial area of high pressure east of our region warm and moist air will continue to advect in. A weak shortwave across northeastern PA into the Western Catskills along with a lake breeze off of Lake Ontario look to be triggers for some scattered showers and thunderstorms this afternoon and evening. Some instability will be present so it is not out of the question a storm or two could produce a downburst. However, shear still looks very week today preventing any storm organization for a more sustained threat of strong to severe thunderstorms. Also, if some areas get multiple thunderstorms poor drainage flooding would become possible. Temperatures should warm well into the 80's. With the increasing moisture, lows look several degrees warmer tonight in the low to mid 60's. Given light winds, additional patchy fog is possible. Another mid-level shortwave Tuesday looks to track through the Mid-Atlantic to trigger off scattered showers and thunderstorms mainly southeast of our region. Another summer day with highs in the 80's once again. && .SHORT TERM /TUESDAY NIGHT THROUGH THURSDAY/... 300 AM Update... Ridging building in Tuesday night into Wednesday will make it warm and dry. With the jet stream lifting well to the north and low level SW flow, dew points will rise into low to mid 60s by Wednesday afternoon along with temperatures rising to around 90. For Wednesday night, there has been a trend towards a more robust MCS that develops in the Midwest associated with a stronger 500 mb shortwave. While Thursday was looking dry but hot, now with the MCS and associated shortwave, precipitation chances were added as well as cloud cover increased. Highs were lowered a couple degrees from yesterday though dew points were raised as there is stronger southerly flow ahead of the shortwave. With the dew points so high, the apparent temperature in the afternoon will still get into the mid to upper 90s despite more clouds and chance for showers. With the shortwave passing through, shear is trending stronger as the MCS moves in, with almost 40 knots of 0-6 km shear. If the MCS could form into an MCV before getting into our region, then we could be looking at a better chance at some better organized convection overnight Wednesday into Thursday. && .LONG TERM /THURSDAY NIGHT THROUGH SUNDAY/... 300 AM Update... The long term is looking warm and unsettled. Friday is still looking warm but the mean flow is a bit more westerly compared to previous days and with more instability plus less capping, there will likely be more clouds and some showers and thunderstorms. Temperatures were kept similar to yesterday with no further raises to the high temperature. Dew points are still going to be un the upper 60s and low 70s so it will still be easy to get heat indices into the 90s. The jet stream sags back south for the weekend. Given the zonal flow and the jet stream almost overhead, shortwaves rising around the ridge will likely lead to frequent chances of showers and thunderstorms into early next week. Precipitation chances have been kept to chance or lower due to the unknown timing of these shortwaves. && .AVIATION /12Z MONDAY THROUGH FRIDAY/... Mainly VFR throughout the TAF period. Isolated showers and thunderstorms this morning giving way to scattered showers and thunderstorms this afternoon. Coverage and timing uncertainities are still present but did indicate broad TEMPO groups for the highest chances at each TAF site. Another round of patchy valley fog overnight primarily at KELM. Outlook... Tuesday through Wednesday...Isolated thunderstorm cannot be ruled out Tuesday, and predawn valley fog each night at KELM, otherwise VFR. Wednesday night through Friday...Chance of thunderstorms and associated restrictions, especially by Friday as a front moves into the area. && .BGM WATCHES/WARNINGS/ADVISORIES... PA...None. NY...None. && SYNOPSIS...MWG NEAR TERM...MWG SHORT TERM...AJG LONG TERM...AJG AVIATION...MWG
