RENSSELAER, NY – A cool, faint sunrise greeted the Hudson Valley on Saturday, with breath-halo air and a hint of sparkle on rooftops west of the river. The calm spell of fall weather will hold through Monday, but overnight chills are expected to bring the season’s first spotty frost to rural valleys east of Albany.
Forecasters at the National Weather Service in Albany say a strong area of high pressure will keep skies mostly sunny with daytime temperatures in the low to mid-50s. With clear skies and light winds tonight, temperatures will tumble quickly into the 30s, setting up a brisk start to Sunday. While Sunday afternoon remains mild and bright, colder air slipping south out of the Adirondacks by early Monday will support another frosty morning—particularly in Hudson River lowlands and across Rensselaer and Columbia Counties.
Early commuters using I‑87 and I‑90 on Monday should stay alert for patches of fog in low-lying spots where frost formed overnight. Gardeners should protect cold-sensitive plants and move tender potted herbs indoors through midweek.
The quiet pattern persists into Tuesday: dry air, gentle breezes, and comfortable sunshine—perfect for leaf raking, fall cleanup, or getting a head start on Halloween decor before showers arrive later in the week. By Wednesday, clouds will increase and slightly milder temperatures will hint at a turn toward wetter weather heading into Halloween on Friday.
November is likely to lean chilly, and this serene stretch may be one of the last before winter begins to edge in.
Five-day outlook for Rensselaer, NY:
– Saturday: 54/37 — Mostly sunny; light breeze and a cool evening.
