Snow showers expected overnight

Weather report from Mark McLean, weatherman for 13WHAM, The Batavian's news partner:

Ultimate Doppler HD shows that the intense lake snow band from Lake Erie is weakening and drifting to the north shore of the lake. This is away from the areas that got buried yesterday. Also note on the wider view that another storm system is headed our way now. This storm will deliver a general light snow in WNY late this afternoon and this evening.

Check out the snow accumulation on the futurecast. Snow amounts will be generally light with this afternoon’s storm system. A coating-2” will be possible by late evening in WNY. Much heavier snow will develop overnight southwest of Rochester once more as lake snow from Lake Erie cranks up again. Several feet of snow will be possible in sustained lake snow areas in Genesee and Wyoming counties tonight and Thursday with a solid 3-6” possible in northern Livingston County as well.

Currently it’s frigid in WNY. Many areas have temperatures in the upper teens or low 20s with single digit wind chills and that noticeable wind out of the south. Local spotters show temperatures in the low 20s at this point. The neighborhood forecast shows the light snow moving in late this afternoon, but the temperature won’t fall. We’ll see the readings stay in the mid-20s throughout the night. On the wider view, the futurecast finally shows this intense lake snow band breaking up early Friday morning southwest of Rochester. Closer to Rochester some lake snow from Lake Ontario will be possible Friday, but this snow will be much less intense than the snow observed in Buffalo yesterday.

The forecast for today shows increasing clouds at 3 p.m. with a temperature near 24 in Rochester. By 7 tonight we expect some snow showers. The temperature will be in the mid-20s. At 10pm the general light snow will taper, most areas will see a coating -2” of snow. Tonight’s low will be in the mid-20s with snow showers and flurries near Rochester. Areas south of the Thruway may find up to 12” of snow by sunrise, especially in Genesee and Wyoming counties.

The 7-day forecast does show some slow improvement by the weekend. Any lake effect snow Friday will taper heading into Saturday. Friday’s high will be near 30 with Saturday’s high near 40. A few rain showers will move in for Sunday and Monday, but the temperature will be dramatically warmer. Sunday’s high will be near 50 with Monday reaching 57. All signs point to another substantially colder air mass moving in for mid-late of next week.
