177 FXUS61 KBGM 291754 AFDBGM Area Forecast Discussion National Weather Service Binghamton NY 154 PM EDT Fri Aug 29 2025 .SYNOPSIS... An upper level low will move east of the region bringing an end to the spotty showers tonight. High pressure then builds for the weekend and most of next week. High pressure gives way to a frontal passage by later next week. && .DISCUSSION... A broad upper level low will slowly move east across northern New England as high pressure builds into the region at the surface this weekend. Some slight instability and weak moisture flow off of Lake Ontario keeps the potential of spotty rain showers into the evening hours tonight. Skies should clear out with patchy valley fog possible yet again overnight. Another chilly night with lighter winds and clear skies with lows in the 40`s. Slightly steeper low level lapse rates in the daytime this weekend should fire off some scattered afternoon cumulus clouds. Overall though the weekend is looking mostly sunny with a slow warming trend starting. Surface high pressure currently looks to hang firm till about Wednesday. Once the high shifts north and east of the region A slow warming trend with a bit higher humidity should occur due to southerly flow. Highs by the middle of next week should get close to 80 with lows back up in the 50`s. Actually fairly good ensemble agreement for a frontal boundary to sweep through the region with low pressure forming out ahead of it to warrant the mention of showers Thursday into Friday. This should drop the high temperatures slightly each day as well. && .AVIATION /18Z FRIDAY THROUGH WEDNESDAY/... Most taf sites have now returned to VFR this afternoon, with ITH still showing a bkn MVFR CIG. Even here, based on satellite trends expect improvement to VFR conditions by 20z. VFR conditions are then expected to prevail areawide into this evening with decreasing clouds. Winds will be breezy this afternoon, out of the west-northwest at 8-15 kts with a few gusts close to 20 kts at times. After midnight and into the predawn hours Saturday, there is a good chance for IFR/LIFR fog formation at ELM. High pressure is expected to build in from the west, with winds diminishing and decoupling. Overnight lows will be cold here, well below the crossover temperature and well below local water temperatures in the nearby river. This should facilitate river valley, radiational fog formation. Best chance for the lower VSBYs/CIGs should be between about 08-12z early Saturday morning. The fog should lift and scatter out by 13-1330z. Our remaining taf sites should remain VFR overnight and through Saturday. Winds will become light and variable overnight into Saturday morning, then NW at 8-15 kts on Saturday once again. Outlook... Saturday Afternoon through Wednesday...Mainly VFR with high pressure building in and lake effect winding down. Valley fog possible at or near ELM most mornings. && .BGM WATCHES/WARNINGS/ADVISORIES...
