285 FXUS61 KBUF 050712 AFDBUF Area Forecast Discussion National Weather Service Buffalo NY 312 AM EDT Sat Sep 5 2026 .WHAT HAS CHANGED... Minimal changes with this forecast update. && .KEY MESSAGES... 1.) Widely scattered and isolated showers possible Saturday and Sunday, though primarily dry weather will dominate through Labor Day. && .DISCUSSION... KEY MESSAGE 1...Widely scattered and isolated showers possible Saturday and Sunday, though primarily dry weather will dominate through Labor Day. Mid-level trough centered over New England today, will gradually exit east into the north Atlantic through the holiday weekend, placing the eastern Great Lakes beneath northwest flow. While the trough exits east a few disturbances will dive southeast across the region. Meanwhile, at the surface, high pressure over the upper Great Lakes this morning will slide southeast across the eastern Great Lakes towards the mid-Atlantic by Monday. Overall, mainly dry weather will prevail throughout this holiday weekend, however with each shortwave disturbance passage a few widely scattered and isolated showers will be possible. Otherwise, expect near-average to slightly below average temperatures through the weekend. Lingering moisture, cool temperatures, and calm winds will yield patchy river valley fog across the Finger Lakes, east of Lake Ontario and across the western Southern Tier every night. && .AVIATION /07Z SATURDAY THROUGH WEDNESDAY/... Mainly dry weather and VFR conditions prevail this morning, however clearing skies and calm winds will support patchy fog to develop early this morning, especially for areas in valley locations. Within fog and low stratus, MVFR to IFR conditions are likely. Surface high pressure across the upper Great Lakes this morning will gradually slide southeast through the weekend. While this will lead to mostly dry weather today, increasing moisture ahead of a shortwave trough disturbance will support periods of MVFR ceilings for areas east of Lake Ontario, impacting KART. Additionally, a few showers will be possible across the North Country late this morning and through this afternoon. Otherwise, further west expect dry weather and VFR conditions to prevail. Outlook... Saturday night through Tuesday...Mainly VFR. River valley fog with local IFR each late night and early morning across the Southern Tier. Wednesday...MVFR/VFR with showers likely and a chance of thunderstorms. && .MARINE... A surface ridge will gradually build southeast across the eastern Great Lakes and towards the mid-Atlantic through the holiday weekend. Overall light winds of 5 to 15 knots and waves of 3 feet or less through the holiday weekend. As the ridge exits midweek, a warm front will pass across eastern Lake Erie and Lake Ontario, causing winds and waves to freshen where Small Craft Advisory criteria will likely be met. && .BUF WATCHES/WARNINGS/ADVISORIES... NY...None. MARINE...None. && $$ DISCUSSION...EAL AVIATION...EAL MARINE...EAL

Mountain & avalanche safety

Know before you go
Check today's avalanche bulletin from the regional avalanche center before any off-piste / side-country / backcountry travel. Conditions can shift dramatically between morning and afternoon on storm days.
Carry the gear, know how to use it
Beacon, shovel, probe. Practice companion rescue on a calm day, not during a real burial.
Mind the weather window
Heavy snow + wind builds wind slabs at ridgelines. The day after a storm is often the riskiest in the backcountry, even if the resort itself is open.
Respect closed terrain
Ropes are there for a reason. Even in-bounds, ducking a closure can trigger a slide that catches you and others below.

FAQ

About Mount St. Louis Moonstone

Where does the snow data for Mount St. Louis Moonstone come from?

Snowpack, SWE, 24-hour snowfall, and air temperature come from the nearest USDA NRCS SNOTEL station. Forecast comes from the National Weather Service / yr.no feed that Snoflo's iOS app uses.

How often is the snow report updated?

Snowpack and SNOTEL data are updated continuously by NRCS (typically hourly). The 15-day weather forecast is refreshed throughout the day. Snoflo caches and renders the most recent observation -- look for the "as of" timestamp on the snowpack hero.

What's the elevation at Mount St. Louis Moonstone?

See the Resort Metrics panel above for base / summit / vertical drop. The summit elevation drives snowpack accumulation -- higher summits hold snow longer through spring.

How is "% of normal" calculated?

Today's snowpack is compared to the average snowpack on this calendar day across every recorded year at the nearest SNOTEL. 100% means right on average; 130% is a big year; 60% is thin.

What ski resorts are near Mount St. Louis Moonstone?

See the Other Ski Areas pill grid at the bottom of the page for resorts within driving distance. The sister Other Ski Areas card in the Plan-a-longer-trip grid above shows the closest few.

Can I get alerts when fresh snow hits?

Yes -- snow alerts are managed in the Snoflo iOS app. Favorite this resort, set a snowfall threshold (e.g. "alert me when 6+ inches"), and you'll get a push the moment the SNOTEL crosses.
