After a nice tranquil, milder Thursday, the weather will become a little unsettled later tonight into Friday with the first of many waves of low pressure due to move through tonight through the weekend. Initially, the precipitation later tonight will begin as a little snow/mix, but will changeover to a few rain showers & drizzle late tonight. Little, if any, accumulation is expected.
Friday will feature some off & on rain showers & drizzle & areas of fog. Highs will range from 40 to 45.
Rain showers will taper to drizzle & maybe a little freezing drizzle &/or flurries late Friday night/early Saturday as the air turns a little colder behind a cold front that should sneak through Friday evening.
A large Arctic high across Southern Canada & the Northern Plains will extend itself into Southeastern Canada & the Northeast to kick off the weekend Saturday. This will likely set the stage for some icing on Saturday & possibly Saturday night. The big question is WHEN will the icy mix changeover to rain? At this point it looks like it will happen Saturday night, but the longer it takes for this change to occur the icier everything will get, especially the untreated surfaces including power outages. Precipitation will likely become heavy Saturday night before tapering Sunday. On Sunday we feel quite confident we will just be dealing with some rain showers tapering to a few showers during the late morning & afternoon. Highs will go from the 30s Saturday to the 40s Sunday, as the main storm moves across the area. No matter what happens this weekend, it will turn much colder early to mid next week with a little lake snow possible later Monday through the start of Tuesday, which will hopefully at least ensure us of a somewhat white Christmas anyways. Stay tuned for updates here on the blog, News 8 & our website rochesterhomepage.net This is a very tricky forecast & one that needs to be monitored very closely, as the ultimate track of the storm will dictate what type & the amount of precipitation we see this weekend...
