Rochester, N.Y. — Winds have weakened, placing us back to Green on the Threat Tracker. Only a few passing lake-effect showers appeared this morning, but the rain chances will fade by afternoon, giving way to partly to mostly sunny skies and highs in the mid-40s.
Today’s winds remain calm, with gusts around 20 mph. Conditions will change tomorrow as a new front moves in, bringing gusts near 30 mph and rain in the afternoon and evening.
Saturday will stay cool and cloudy with lighter winds. By Sunday, a low-pressure system passes the region, delivering rain locally while communities across the lake may see the season’s first snow.
"Cold air will wrap around the system Sunday night, giving us our first chance for snow. The higher elevations have the best chance to see flakes."
On Monday, colder air from Canada moves south, boosting lake-effect snow chances as northerly winds strengthen. Temperatures will remain below freezing, with both Monday and Tuesday staying in the 30s.
By Tuesday, winds shift northwest, increasing the likelihood of lake-effect snow off Lake Ontario. While significant accumulation isn’t expected yet, more precise forecasts will come in the next few days.
