Nice disco from BUF...
Off Lake Erie... Band of moderate to heavy snow with snowfall rates of 2+" per hour along with some thunder continues to lift northward, focusing along the Lake Erie shoreline of Chautauqua county to just south of the Buffalo Airport to near Batavia. Approach of low level trough backing winds enough to lift the band northward a bit more than mesoscale models suggested, but with the passage of the trough the band should refocus south of the Buffalo metro area for a time overnight. However, this should be brief as nearly all mesoscale guidance drifts the band northward toward morning, reaching its northern-most point late in the morning to early afternoon Saturday into the city of Buffalo and even the nearby northern suburbs before starting to drift back south across the southtowns late in the afternoon. Lowering inversion heights, decreasing moisture, and increasing shear will allow the band to weaken Saturday afternoon. Total accumulations of 15-20 inches are still likely where the band persists the longest from western Chautauqua County, the northwest corner of Cattaraugus County, into southern and central Erie County including South Buffalo and the densely populated nearby southtowns. 6-12 inches are possible from downtown to the airport and the nearby northtowns if the band makes it that far north Saturday, with a very sharp drop off in accumulations heading northward through the northtowns.
