677 FXUS61 KALY 310745 AFDALY AREA FORECAST DISCUSSION National Weather Service Albany NY 345 AM EDT Fri May 31 2024 .SYNOPSIS...
-- Changed Discussion --
Clear skies and light winds will yield seasonably cool temperatures across the region this morning, before moderating through the day. Nearby surface high pressure will see gusty west to northwest winds this afternoon, with otherwise continued fair weather into the weekend. Temperatures will trend above normal into early next week.

&& .NEAR TERM /THROUGH TONIGHT/... Upper ridging and surface high pressure approaching from the west will bring continued fair weather through tonight. With light winds beneath clearing skies, much of the region is in for a cool morning, with areas above 1500 ft elevation starting the day in the upper 30s, while lower elevation locales begin in the low to mid 40s. Steep low-level lapse rates up to 800-850 hPa developing by this afternoon will allow for some stronger west to northwest winds to mix down to the surface, potentially gusting as high as 20-25 mph along the Mohawk Valley, across the Capital District, and in the higher terrain of the eastern Catskills and Berkshires. Some higher clouds may pass over the region through the afternoon, with otherwise mostly sunny skies and temperatures moderating to near normal values, reaching afternoon highs in the 60s in higher terrain and low to mid 70s at lower elevations. Another night of largely clear skies and light winds will again see efficient radiative cooling, resulting in overnight lows in the 40s for most of the region. && .SHORT TERM /SATURDAY THROUGH SUNDAY NIGHT/...
-- Changed Discussion --
Pleasant weather continued into the weekend as upper ridging approaches from the west on Saturday and passes overhead on Saturday night. Temperatures reach a few degrees above normal beneath mostly sunny skies through the afternoon, reaching highs in the upper 60s to mid 70s in high terrain and upper 70s to mid 80s at lower elevations. Mid to high clouds begun to increase from the west into Saturday evening and night, as temperatures fall to overnight lows in the upper 40s to mid 50s. On Sunday, the upper ridge will begin to stretch out as it becomes squeezed between upper troughing over Hudson Bay to the west and a deep upper low off the Canadian Maritimes to the east. An upper shortwave riding up the western flank of the ridge will weaken somewhat and begin to slow as it approaches, with scattered rain showers ahead of a surface frontal boundary reaching into the region Sunday afternoon and evening. Enhanced cloud cover and spotty showers may knock a few degrees off of temperatures compared to Saturday, with afternoon highs in the mid 60s to upper 70s expected. Higher surface dewpoints additionally limit overnight cooling, with lows Sunday night in the 50s across the region.

&& .LONG TERM /MONDAY THROUGH THURSDAY/...
-- Changed Discussion --
An upper level shortwave looks to depart the region to the east on Monday as upper-level ridging attempts to return into midweek. High pressure will dive southward from Canada and set up along or just off the New England coast. This high should provide enough subsidence for mainly dry weather, but some pop up showers and thunderstorms cannot be ruled out either day, but looks more on the isolated side. NBM PoPs continue to look a bit too aggressive for Tuesday and Wednesday, especially compared to the latest deterministic models which show a drier trend, so trimmed them back slightly, but maintained some slight chance to low chance for now. The better, more widespread, rain chances look to be toward the end of the week as an upper-level trough/low tracks eastward from the central CONUS, sending a cold front toward our area. Overall forecaster confidence on the long term period remains low to moderate as run-to-run model consistency during this period remains poor. Highs will be mainly in the 70s/80s each day with lows in the 50s to lower 60s.
