The vast majority of the Finger Lakes will be quiet today, with a mix of sun and clouds. For a 10-20 mile wide stripe running roughly along Route 38, it might as well be mid-winter all over again.
A narrow, but very impressive band of lake effect is bringing heavy snow, poor visibilities and difficult travel to parts of the eastern Finger Lakes this morning. This band moved into the area from the northeast between 5-6 am and will stay in about this position until the mid to late morning hours.
In the heaviest, consistent parts of the band, a few inches of snow could fall, with upwards of 6″ possible if the band remains in place long enough.
Lake effect can be unpredictable, and computer model guidance is doing a poor job with this event, but it should weaken and move back to the northeast by midday. Areas west of Cayuga lake and south of Route 20 should generally stay dry today.
Temperatures will be mostly in the upper 20s over the eastern Finger Lakes, where clouds and snow will linger. Further west though, temperatures will be a bit warmer, with low 30s.
The threat for at least some flurries will continue east of Cayuga Lake into tonight. Thursday should be dry before the southern parts of the region get clipped by some snow on Friday.
