Low pressure riding up along a frontal boundary just to our south and east will provide us with some flurries and light snow showers across the region through the overnight. The overall storm track looks to be far enough south and east that we will just be on the back side of this system, so in terms of accumulation, a coating for most around the Rochester area, but further south a few inches are likely. Especially south of Routes 5 & 20, 1-3" will be a good bet with a few localized higher amounts.
The snow will taper off from west east late tonight with lows dipping back into the mid and upper 20s.
Into Saturday, not looking at much more than some lake flurries around initially, otherwise clouds part for some sunny breaks from time to time. Remaining chilly with highs in the low 30s and then falling late.
High pressure will move into the area Sunday, but look for increasing clouds ahead of our next system. Sunday night a warm front draws closer to the area. It appears that we will find some snow overspreading the area but we will have to watch for the potential of a wintry mix late Sunday night into early Monday as the warmer air lifts up across the colder surface temperatures. The good news is that we should quickly climb back into the 40s on Monday, so any mixed precipitation will change over to just rain. As a cold front spreads eastward, expect the mercury to drop back into the 30s late in the day.
Following this brief warm up, it appears that we will quickly transition back into mid-winter conditions by the middle of next week with bitter cold air moving into the Great Lakes along with areas of lake snow showers. Temperatures will be below normal with highs only in the mid-20s.
