Clouds will gradually be clearing out into Saturday morning, with a decent amount of sunshine by tomorrow afternoon. Even still, a much colder air mass in place will mean temperatures should stay in the 20's throughout Saturday. This high will be directly overhead Saturday night with mostly clear skies, so lows will fall quickly into the lower teens and potentially upper single digits for a fairly cold night. This all changes quickly Sunday as southerly winds kick in and temperatures jump to the middle and upper 30's and clouds increase once again.
This next storm system will extend a boundary from the Great Lakes all the way to the Southeast, setting up a direct funnel of warm air into the Twin Tiers. With some colder temperatures at the surface at first, some mixed precipitation could be seen Monday morning, but after that we'll see all rain. This could be heavy at times east of I-81 into the afternoon, before a steady light rain takes over all the way through Tuesday. Recent data has shown that with snow melt and overall rainfall, some minor flood issues along small streams and creeks is looking possible early next week. These should be manageable however, and will be a point to monitor going forward.
Much colder and drier air arrives for late next week, though stiff northwest winds will again kick up lake effect snow showers next Wednesday before partly cloudy skies next Thursday and Friday. Highs will generally be in the 20's with lows down into the teens.
