A fast moving system will clip the Finger Lakes with some snow on Friday.
WHAT
A clipper system will dive southeast across the region during the day Friday. The center of low pressure should work directly overhead, which means the heaviest snow will stay north and some milder afternoon temperatures will move in.
ALERTS ACTIVE
No alerts are in effect or are expected for this system.
WHEN
Snow will enter the region from northwest to southeast in the hours just before and just after sunrise. Areas such as Rochester and Canandaigua should see snow before the sun is up, while areas like Ithaca and Cortland will probably not see flakes fly until after the sun comes up.
The snow will continue through the morning before becoming less widespread during the afternoon. Areas along and south of roughly Route 20 (Canandaigua-Geneva-Auburn-Skaneateles-Lafayette) may see some rain mix in, or precipitation come to an end all together.
After sunset Friday, a couple brief, isolated squalls may develop southeast of Lake Ontario across Wayne, Cayuga, Onondaga and perhaps northern Cortland counties.
HOW MUCH
The greatest potential for two inches or more of accumulation will be near the Lake Ontario shore. Most of the Finger Lakes will see a coating to an inch, with little to no accumulation in the Southern Tier.
Lake effect squalls Friday night could bring another inch locally in the areas described above.
TEMPERATURES
Temperatures will be on the rise early Friday, nosing into the low 30s as the snow starts. By the afternoon, temperatures will range from 35-40 degrees with the warmest temperatures coinciding with the T-1” range on the snow map.
TRAVEL IMPACTS
During the morning , rural and secondary roads may become snow covered and slick. Main roads should generally remain wet, but if left untreated and lightly traveled, could have a few slick spots.
By the afternoon, roads will be generally wet as temperatures climb above freezing. A few rural roads north of I-90 may remain slushy.
Evening travel will have minor impacts in the lake effect belts, but the rest of the region should have no impacts.
OTHER IMPACTS
Winds Friday afternoon could gust over 30 mph as they shift from the south to the west following the passage of the low pressure center.
FORECAST CONFIDENCE
HIGH- The weather should unfold generally as explained above. Localized variations in snow amounts are inevitable, but should not be far from the forecast range.
FUTURE SNOW OUTLOOK
A few lake effect snow showers may linger into early Saturday morning, but should quickly move north and dissipate.
Rain Monday and early Tuesday may end as some snow later Tuesday with lake effect possible Wednesday next week.
