537 FXUS61 KALY 140804 AFDALY AREA FORECAST DISCUSSION National Weather Service Albany NY 404 AM EDT Sat Jun 14 2025 .SYNOPSIS... With our area on the northern side of a frontal boundary, it will remain cool for today with plenty of clouds and some passing showers, mainly for this morning. A few breaks of sun are expected on Father`s Day, but there still could be a shower around with temperatures on the cooler side. Temperatures are expected to moderate during the upcoming week, with highs back above normal towards the middle of the week, along with the chance for some afternoon showers or thunderstorms. && .NEAR TERM /THROUGH TONIGHT/... As of 403 AM EDT...A stalled out frontal boundary is located south of the region over the mid Atlantic States along with PA/MD border. A weak wave of low pressure has been developing along the front and it will be sliding eastward through the morning hours. Surface high pressure has been located north of the area, and this has been keeping cooler air over the area, with the low level flow out of the north. Meanwhile, the flow aloft is fairly zonal and there is a weak upper level disturbance moving through the flow across the region. The combination of the stalled surface boundary and the weak upper level feature is allowing for a widespread area of rainfall over Pennsylvania, with additional areas of showers over Upstate New York and into western New England. IR saTellite imagery shows fairly cloudy skies over the area and surface observations shows widespread overcast mid level clouds in place. Through the morning hours, periods of on and off showers will spread west to east across the region. Most of this activity will be occurring south of the Adirondacks. With the best moisture off to the south, rainfall rates won`t be anything too excessive. NYS mesonet observations have been showing rainfall rates generally under a tenth of an inch per hour, with MRMS estimating rates up to a quarter of an inch per hour within the brief heavier bursts. With the manageable rainfall rates, no hydro impacts are expected from this rainfall and the bulk of the activity will be through about Noon or so. The highest QPF looks to be across southern areas, although the probability for total rainfall over an inch is under 15% and even 0.50" is under 50% for the entire area. With a stable air mass in place, no thunder is expected and SPC HREF shows any elevated instability looks to remain south of the region, so won`t include mention of this in the forecast at this time. After noon, most of the rainfall will be done, so will trend POPs down from north to south through the late morning hours. Some breaks of sun are possible during the afternoon, especially for northern areas, but most areas will be staying fairly cloudy with the surface front still off to the south. Highs today will generally be in the 60s, although some low 70s are possible in northern valley areas where some sun may occur. For tonight, the frontal boundary will start shifting southward. The high pressure area off to the north and east will continue to keep some cool, drier and stable air in place, so little additional precip is expected overnight. While southern areas will stay fairly cloudy, partly cloudy skies are expected from the Capital Region on northward. Lows look to be in the 50s. && .SHORT TERM /SUNDAY THROUGH MONDAY NIGHT/... Slow moving frontal boundary will continue to shift southward across the mid Atlantic on Sunday, while surface high pressure remains anchored to the northeast of the area. This high pressure area will continue to funnel cooler and more stable air into the area. A broad upper level trough will remain over the area for Sunday (Father`s Day). Although forcing is rather weak, a stray shower or two can`t be ruled out (mainly for western and northern areas), although most places will stay fairly dry. There should still be a fair amount of cloud cover around, although probably more breaks compared to Saturday. Temps will still be on the cooler side, with afternoon temps in the mid 60s to mid 70s. It will stay partly to mostly cloudy and fairly quiet into Sunday night with lows in the 50s. Mainly quiet weather will continue into Monday and Monday night. The low level flow will start to become more southerly as the high pressure area shifts away. Heights and temps aloft will start to rise on Monday. There still could be a brief afternoon shower for western areas, but most spots look to stay dry once again. Temps will be milder compared to the weekend, with afternoon highs reaching the mid to upper 70s in valley areas. Dewpoints still will be similar in the upper 50s for most spots. Overnight lows will generally be in the mid to upper 50s with a partly to mostly cloudy sky. && .LONG TERM /TUESDAY THROUGH FRIDAY/... Unsettled conditions will ensure scattered, garden-variety showers Tuesday and Wednesday with temperatures continuing to trend farther above normal. Isolated to scattered rumbles of thunder also cannot be ruled out Wednesday with guidance showing modest amounts of instability across the region. High temperatures Tuesday will widely reach the 70s with pockets of low 80s in the valleys. Lows Tuesday night will fall only to the upper 50s to low 60s before we warm to the mid 70s to mid 80s Wednesday. Wednesday night`s lows will be even more mild than Tuesday night with values widely in the 60s. Thursday will be the day to monitor closely over the coming days as it holds the better chances for potentially stronger thunderstorms. Throughout the day Wednesday, a deepening shortwave trough and associated surface low will eject north and eastward from the Plains, helping to lift a once stationary boundary northward through the region as a warm front. By Wednesday night, the axis of the shortwave becomes situated across the Great Lakes and Ohio Valley with the surface low moving out ahead of it into the northeastern Great Lakes. As a result, we will fall into the warm sector of the surface cyclone Thursday with the attendant warm front displaced to our north and the trailing cold front still well upstream. NBM probabilities for at least 1000 J/kg of SBCAPE range from 60-90% given the regionwide, extensive heat (highs in the mid/upper 70s to low 80s and possible pockets near 90) and high humidity (dewpoints in the mid 60s to mid 70s) with probabilities for at least 1500 J/kg around 30-60%. While forecast soundings this far in advance need to be taken with a grain of salt, there are indications of steep low- level lapse rates, some inverted V profiles, rapid storm motion, and moderate DCAPE that are, at this time, yielding the potential for strong wind gusts resulting from any developing thunderstorms. Now, all that said, there remain some uncertainties in the timing and track of the aforementioned system. These components of the forecast will greatly impact the resulting extent or lack of convection. We will continue to monitor trends closely moving forward. Friday also remains a bit uncertain at this time given the timing discrepancies in the depiction of Thursday`s system. However, maintained scattered chance to chance PoPs to account for the slower timing of the system which would keep showers around in the wake of the primary front and ahead of the secondary cold front on the back side of the system. Lows Thursday night will be similar to those of Tuesday night. Highs Friday will be in the upper 60s to low 80s with lows cooling to the 50s and low 60s Friday night. && .AVIATION /08Z SATURDAY THROUGH WEDNESDAY/... Through 06z Sunday...VFR conditions currently prevail across all terminals as batches of showers and a small area of continuous rain (near KPOU) move in across the region. Forecast soundings showing an increased amount of low-level dry air has led to the more optimistic TAF forecast for the 06z period than previous issuances. Confidence has increased all the more in this element of the forecast as some showers have passed through terminal boundaries within the last couple hours and no observations have indicated precipitation reaching the ground. Therefore, though scattered showers will continue to increase in coverage through this morning, TEMPO and prevailing groups containing rain were delayed a bit to provide some time for the column to saturate. Still, forecast soundings indicate ceiling heights primarily remaining within VFR thresholds with brief reductions to MVFR heights at various times later this morning and this afternoon. The exception to this looks to be KGFL where a lack of low-level saturation should prevent conditions from escaping VFR thresholds. Rain and showers will conclude later on this morning for most, but lingering light, continuous rain should continue into the early afternoon at KPOU. Winds throughout the period will be light and variable with sustained speeds remaining under 10 kt. Outlook... Sunday Night: Low Operational Impact. Slight Chance of SHRA.
