Area Forecast Discussion National Weather Service Binghamton NY 233 PM EDT Sat Apr 15 2023 .SYNOPSIS... A weak upper level low pressure system will move across northeast Pennsylvania this afternoon and evening, producing scattered showers and a few thunderstorms into tonight. A strong cold front will push through Sunday night and Monday with another round of showers. A brief cool down is then expected Tuesday and Wednesday before warming up again near the end of the week. && .NEAR TERM /THROUGH SUNDAY NIGHT/... 230 PM Update... Slow moving thunderstorms, generated from an upper level low that will track over NE PA afternoon and evening, will bring a threat for thunderstorms, torrential downpours and localized flash flooding. Even with very dry antecedent conditions, short corfidi vectors and very weak flow aloft indicate potential for slow moving back building cells this afternoon into this evening. Rainfall rates in storms may reach as high 2" per hour and flash flooding will be possible if storms persist over any one location for more than an hour. Also, with freezing levels are only around 8K feet and with MU CAPE values of 1000 - 1300 J/kg, small to borderline severe hail will be a threat for this afternoon and into this evening. The upper level low will move east of the region tonight and showers/thunderstorms will come to an end. Tomorrow is now looking mostly dry, as upper low should be far enough to our east to prevent further shower activity. However, a strong cold front will push into western NY late Sunday night into Monday morning. This front will bring the potential for showers and embedded thunderstorms during the early morning hours on Monday, but all CAMs currently have an area of convection weakening as it heads eastward across our region. This front will bring a big weather change to the region, as temperatures will for the the start of next week looking to be some 30 to 40 degrees cooler than this past week. More on that below. && .SHORT TERM /MONDAY THROUGH TUESDAY NIGHT/... 2 PM Update A much more unsettled and cooler weather pattern expected for this period. A frontal boundary will push through Central NY and Northeast PA with a band of slow moving rain showers Monday morning. By midday or afternoon there looks to be a narrow dry slot over much of the area, with diminishing chances for showers, and perhaps a few breaks in the clouds. Then, the upper level low presses in from the west, with moisture again increasing by late afternoon and early evening, with additional showers popping up. QPF amounts are forecast to range from around 0.10 to 0.50 inches on Monday, with the higher end amounts east, across the Catskills and Mohawk Valley regions. Temperatures aloft start to fall reaching around 0C late in the day, then -5C overnight at 850mb. Occasional showers continue Monday night under the influence of the mid and upper level low, along with some possible lake enhancement in a west-southwest flow regime. High temperatures on Monday reach the mid-50s to lower 60s, then falling into the 30s or around 40 for low Monday night. On Tuesday, the mid and upper level low will be directly over, or just north of our area. 850mb temperatures remain cold, between -5 to -8C over the region. Showers are likely in the cold, moist and unstable cyclonic flow, especially over Central NY, fading to slight chance and chance PoPs over NE PA. As temperatures drop into the low to mid-30s Monday night and Tuesday morning, some wet snow showers could also mix in with the rain, especially for higher elevations of CNY and the northern tier of PA...little to no accumulation expected. Tuesday night, the upper level low/trough moves off to the east of our area, but we remain on the cold northwest flow behind it..with 850mb temps still around -7C for the first half of the overnight period. There will be a chance for lingering rain and snow showers over CNY, gradually shifting north and east through the night. Expect chilly overnight lows in the upper 20s to mid-30s. && .LONG TERM /WEDNESDAY THROUGH SATURDAY/... 2 PM Update Heights begin to rise on Wednesday, as a warm frontal boundary develops over the region. A weak surface high pressure will also be in place by afternoon. This should keep our weather dry on Wednesday, with morning clouds giving way to increasing sunshine by afternoon. Seasonable or slightly below average with highs in the upper 40s to mid-50s over CNY, and 50s to lower 60s in NE PA. Operational 12z GFS seems too fast developing precipitation along the warm front Wednesday evening and Wednesday night; therefore stuck with the NBM/Ensemble based PoPs for this timeframe...keeping it dry. Cool Wednesday night, but with some clouds around...which should keep temperatures mainly in the 30s for overnight low, except upper 20s for northern Oneida county. By Thursday, the warm front looks to be bisecting the area, perhaps near the I-90 corridor in CNY. Guidance is still pointing to partly sunny conditions for most of the area, but a slight chance for an afternoon shower was introduced into the forecast. Otherwise, it will be warming up with highs 65-75 across the region. The warm front lifts north slightly Thursday night, with mild temperatures in the 40s to lower 50s forecast, and just a slight chance for a showers. By Friday, our area looks to be in the warm sector out ahead of an approaching cold front and low pressure system over the central Great lakes. Southerly winds will allow temperatures to surge up into the upper 60s and 70s areawide. There will be a chance for showers later in the day, along or out ahead of the aforementioned cold front. There will be some modest instability, so a thunderstorm is also possible. Unsettled weather is expected heading into next weekend, as the upper level trough slides east into our area. The southwest flow brings good moisture transport out ahead of it, with chance PoPs to low end likely PoPs in the forecast next Saturday; cooling down some but still, near to slightly above average temperatures. && .AVIATION /19Z SATURDAY THROUGH THURSDAY/... Upper level low expected to move east/ne across NE PA today. This system will produce scattered showers and a few isolated thunderstorms in NE PA and the Southern Tier of NY in the afternoon. There may be some brief MVFR to IFR restrictions in the heavier showers but not confident enough to put IFR restrictions from showers and storms in the forecast at this time and any storms will have to be handled by amendments. After the showers and storms, the areas that see rain will become favorable for IFR fog and some low clouds after 06Z. Could be IFR to fuel alternate required restrictions from ITH south to AVP. RME and SYR should have lower chances of morning fog/clouds tomorrow given the lower chances for rain today. Outlook... Sunday...Mostly VFR, low chance for showers and associated restrictions in the afternoon. Sunday night through Tuesday...restrictions are possible with rain showers. Wednesday through Thursday...Generally VFR conditions expected. && .BGM WATCHES/WARNINGS/ADVISORIES... PA...None.
