Area Forecast Discussion National Weather Service Binghamton NY 1259 PM EDT Sun May 22 2022 .SYNOPSIS... A cold front moving through this afternoon bringing a round of showers and thunderstorms. Dry and cooler weather returns for the beginning of the work week ahead of of rain chances midweek. && .NEAR TERM /THROUGH MONDAY/... Made only minor changes with the mid morning and noontime updates, mainly to note the debris clouds slowing down destabilzation. Destabilization has been slow to occur as a result cloud cover ahead of the front. CAPE is currently under 500 J/KG. However low level lapse rates are getting steeper to help offset that. A narrow window of sufficient shear is still present to organize thunderstorms into line segments or clusters. CAPE should increase to around 500-1000j/kg across most of the area, especially east of I-81, and bulk shear will be up to 30 to 40kts. Thus, the ingredients are there for more organized severe storms. For its part, simulated reflectivity is favoring somewhat more discrete or multicellular storm mode west of I-81, then storms organize into a broken line as the front enters the more unstable environment to the east during the late afternoon. LCLs are fairly high, with a nice inverted-v shape to model soundings, so gusty winds would be the main threat. Amid such an unstable environment, hail is also possible. SPC has a Slight risk across most of the area apart from the Finger Lakes, given that the front may already be through there by peak heating. Forecast highs are somewhat tricky. As timing of the frontal passage has been slowed ever so slightly compared to previous forecasts, most of the area should be able to peak in the 80s. However, the Finger Lakes may struggle to make it out of the upper 70s as the front should be moving through by the early afternoon. Highs there will occur fairly early in the day, then temperatures rapidly fall back the rest of the afternoon behind the front. Expect otherwise breezy conditions, with winds gusting up to 15 to 20mph. Any showers and storms quickly wrap up into Sunday evening, then high pressure building in will ensure dry weather through Monday. Skies will be cloudy overnight, but with a drier airmass into Monday, more breaks of sunshine are expected during the daytime. Otherwise, temperatures will run much cooler, starting off in the 40s and peaking generally in the 60s. && .SHORT TERM /MONDAY NIGHT THROUGH WEDNESDAY NIGHT/... 1230 PM Update... A ridge of high pressure will result in mostly dry conditions across the region for this period. Temperatures start to trend warmer Tuesday, climbing into the upper 60s and low 70s. Partly sunny skies are also expected. Overnight lows will fall into the upper 40s to low 50s. More widespread 70s are likely on Wednesday, though some higher elevations may fall just shy of 70. A stacked low will move across the upper Mississippi River Valley and into the Great Lakes region during the day, bringing increasing sky cover. Models are starting to trend drier with the ridge still in place on Wednesday. Though there will be a low chance for showers across CNY as a weak shortwave could kick off some isolated showers ahead of this system. A warm front will lift north Wednesday night, possibly triggering some additional showers. With some model guidance trending drier, NBM PoPs were reduced slightly. Overall, PoPs with this update are quite a bit lower than the previous forecast. Temperatures overnight are expected to be in the 50s. && .LONG TERM /THURSDAY THROUGH SATURDAY/... 1230 PM Update... This low pressure system will continue to move northward Thursday as an upper level trough approaches the region. As the low lifts northward, it will push a cold front eastward. Some scattered showers and storms may be possible ahead of the front during the day on Thursday. The best chances for showers and storms will be late Thursday and during the overnight hours as the front passes through. The front moves out of the region Friday morning and dry air pushes into the region, bringing dry conditions to portions of the region. Though, there is still a chance for lingering showers Friday and Friday night, mainly north of the Twin Tiers, from wrap around moisture as this system moves further north and east. Winds will also be gusty both Thursday and Friday with a tighter pressure gradient present near the surface. High pressure will build into the region Saturday, bringing dry conditions and pushing out any lingering showers that may remain. The is some uncertainty for the second half of the weekend due to timing differences with the next system. For now, precipitation chances were capped at slight chance considering this is next system is a week out. Temperatures will be around average for this period, trending slightly cooler into the weekend. Temperatures rebound in the second half of the weekend and will be a bit warmer than average as 80s will be possible. && .AVIATION /18Z SUNDAY THROUGH FRIDAY/... VFR till the arrival of potential showers and thunderstorms in the 18-22Z range. Coverage will not be uniform across our area and some TAF sites may miss out completely. With that mind, continued with TEMPO groups to give a best two hour window for the highest chance of a thunderstorm. Southwest winds will become more westerly and even northwesterly tonight with the passage of a cold front. A couple wind gusts around 20 knots can not be ruled out either. Indications are present for a stratus deck of 1,500-2,500 feet to build into all TAF sites this evening. Some uncertainty is present on how fast this deck moves in and the timing of the ceiling breaking up Monday morning. VFR expected after 13Z Monday though with continued northwesterly winds around 10 knots. Outlook... Monday afternoon through Friday...Mainly VFR, but possible restrictions with stratus decks advancing northwestward through at least KAVP Tuesday and Wednesday nights. Possible showers later Wednesday through Friday too. && .BGM WATCHES/WARNINGS/ADVISORIES... PA...None. NY...None. && SYNOPSIS...HLC NEAR TERM...HLC/MWG SHORT TERM...BTL LONG TERM...BTL AVIATION...MWG
