970 FXUS63 KLOT 200654 AFDLOT Area Forecast Discussion National Weather Service Chicago/Romeoville, IL 154 AM CDT Tue Oct 20 2026 .KEY MESSAGES... - Some ground fog may develop within 10-15 miles of Lake Michigan during early morning hours the next few days. Any fog would then quickly dissipate after sunrise. - An extended period of dry and above to much above average temperatures is expected through the upcoming weekend. && .DISCUSSION... Issued at 154 AM CDT Tue Oct 20 2026 No significant weather is expected through the upcoming weekend with above to much above average temperatures each day. Generally light winds should allow weak lake breezes to form each of the next several afternoons, but only result in slightly cooler conditions right near the lake. A modest increase in moisture in the wake of the afternoon lake breezes could allow for some ground fog to form during the early morning hours the next few days. Otherwise, look for mostly sunny conditions for the remainder of the work week. - Borchardt/Izzi && .AVIATION /06Z TAFS THROUGH 12Z WEDNESDAY/... Issued at 1230 AM CDT Tue Oct 20 2026 Key Aviation Messages for the current TAF period: - Patchy fog possible around sunrise. Winds are expected to be light and variable, if not outright calm through the overnight. There is a chance for patchy fog toward daybreak for Chicago terminals, with better chances closer to the lake. There is still uncertainty with how low visibilities will go, but will be monitored through the night. But the expectation is that any fog that does form should dissipate after sunrise for a return to VFR. Light winds will prevail through the day, mostly out of the east. There is another chance for patchy fog tomorrow morning. Given there is little change to the overall weather pattern tomorrow, would like to see how this morning plays out first before adding fog to the TAFs for Wednesday morning.

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 The Mountain Top At Grand Geneva Resort

Where does the snow data for The Mountain Top At Grand Geneva Resort 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 The Mountain Top At Grand Geneva Resort?

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 The Mountain Top At Grand Geneva Resort?

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.
