AREA FORECAST DISCUSSION National Weather Service Albany NY 646 AM EDT Tue Apr 30 2024 .SYNOPSIS... An upper level disturbance and weak cold front will allow for showers and scattered thunderstorms, mainly this afternoon and evening. Drier weather will return for Wednesday with seasonable temperatures. && .NEAR TERM /UNTIL 6 PM THIS EVENING/... Scattered showers and isolated thunderstorms into the western Mohawk Valley and southern Adirondacks, extending into central NY. This area of scattered showers and isolated storms will track through areas along and north of I-90 this morning. Mostly cloudy sky much of the day with some breaks in the clouds in the eastern Catskills, Schoharie valley and western Mohawk Valley. Upper energy and a weak cold front will support development of showers and thunderstorms in western and central NY midday and early afternoon. The leading edge of low level cold advection, boundary layer wind shift and instability will support a line or band of showers and thunderstorms with small hail, gusty winds and locally heavy rain. An elevated mixed layer is expected over our region this afternoon, especially from the eastern Catskills through mid Hudson Valley, NW CT and southern Berkshires, which again, suggests some hail, gusty winds and locally heavy rain. Extensive clouds will limit warming today, with highs mainly in the 60s, with around 70 to lower 70s potentially in parts of the Schoharie Valley and western Mohawk Valley. && .SHORT TERM /6 PM THIS EVENING THROUGH THURSDAY NIGHT/... Showers and thunderstorms linger through tonight with decreasing coverage through the night. There could be just some isolated showers early Wednesday morning, but the weak cold advection, becoming neutral to weak warm advection by Wednesday evening, and lingering upper energy and moisture will result in a very slow break up of the clouds through the day Wednesday. Highs Wednesday in the 60s to near 70. Leading edge of warm advection and then passage of another weak cold front may support an isolated shower in northern areas to southern VT Wednesday night into Thursday morning. Front exits Thursday morning with breezy northwest winds by afternoon and better clearing for at least some sunshine. Highs Thursday in the mid 60s to lower 70s. Remaining dry Thursday night with lows by early Friday morning in the upper 40s to lower 50s. && .LONG TERM /FRIDAY THROUGH MONDAY/... Long term period begins at 12z Friday with an upper ridge axis over western NY. On the downstream side of the ridge, high pressure will be located to our northeast. Subsidence from these features will keep us dry Friday. Highs will be in the 60s and 70s from the Hudson Valley westward, but in western New England low-level east/southeast flow around the surface high will help to keep temperatures slightly cooler with highs in the 50s (terrain) to 60s (lower elevations). Friday night remains dry with lows mainly in the 40s. For the weekend, An surface low becomes vertically stacked in south- central Canada, and its occluded front slowly tracks towards our region. There is some uncertainty regarding the timing of the front, but with the front running into the upper ridge and the best upper forcing well west of our region, will continue to lean towards a slower solution. If the slower solution does indeed verify, much of the day Saturday may be dry, especially east of the Hudson Valley. Chances for showers and possibly a rumble of thunder should increase Saturday night and Sunday. Temperatures will be cooler over the weekend, with highs mainly in the 50s and 60s during the day and overnight lows in the 40s. For the beginning of next week, things look to dry out Monday as a ridge of high pressure builds in from the west. With more sun, temperatures will be warmer, possibly climbing into the 70s again for our valley areas. Another warm front may approach our region from the southwest Tuesday, which could bring some additional shower chances. FOr day 8-14, the CPC is expecting near to slightly above normal temperatures and above normal precip. && .AVIATION /12Z TUESDAY THROUGH SATURDAY/... Through 12z Wednesday...Mainly MVFR conditions this morning, with PSF seeing IFR cigs. GFL is currently VFR, but expecting a trend downwards to MVFR cigs by the start of the 12z TAF period. Showers and thunderstorms currently west of the TAF sites should impact GFL and possibly ALB through the first couple hours of the TAF period. Have included tempo groups and will note that IFR vsbys possible if any heavier showers/storms move over one of the terminals. Showers and storms should end no later than 15z. Once the showers end, mainly dry conditions and VFR vsbys expected through late this afternoon. Cigs remain MVFR and likely fuel-alternate this morning, but trend upwards this afternoon with some VFR especially at ALB/GFL. However, late this afternoon and evening, another round of showers and thunderstorms is expected. Have continued use of prob30 groups to highlight this and have added mention of TSRA to POU and PSF based on latest guidance. Will likely see cigs and vsbys lower to MVFR with the showers, and IFR vsbys are possible with any thunderstorms. Showers end by 3-4z tonight. Expecting borderline MVFR/IFR cigs and vsbys tonight, especially for areas where the ground remains wet overnight from the afternoon rainfall. Winds will increase to 5-10 kt with from the southeast by mid- morning, continuing through the afternoon. Some gusts of 15-20 kt are expected this afternoon, especially at ALB PSF. Behind the line of showers and storms this evening, winds generally remain at 5 kt or less through the rest of the night. Outlook... Wednesday Night: No Operational Impact. NO SIG WX. Thursday: Low Operational Impact. Breezy. NO SIG WX. Thursday Night: Low Operational Impact. NO SIG WX. Friday: No Operational Impact. NO SIG WX. Friday Night: Low Operational Impact. NO SIG WX. Saturday: Low Operational Impact. Slight Chance of SHRA. Saturday Night: Moderate Operational Impact. Chance of SHRA. Sunday: Moderate Operational Impact. Chance of SHRA. && .HYDROLOGY... Showers and thunderstorms north of I-90 overnight have produced a half inch to inch of rain with very localized amounts up to 2 inches. More showers and thunderstorms are expected by later in the day over the entire area as a frontal boundary approaches from the west. The low level flow out of the south will bring in plenty of moisture into the region ahead of the boundary, although dewpoints and PWATs will not be overly excessive for this time of year. Still, the frontal boundary should be strong enough to allow for a fairly widespread areas of showers and thunderstorms. Some of these showers and thunderstorms may contain heavy downpours, which could lead to ponding of water in urban or low lying areas. WPC has placed much of the region within a Marginal Risk for Excessive Rainfall during this period. Overall, rainfall amounts will generally be under an inch and no flooding of main stem rivers is expected. && .ALY WATCHES/WARNINGS/ADVISORIES... CT...None. NY...None. MA...None.
