Storm system set to bring rain Thursday and mixed precipitation Friday

An area of low pressure over the Midwest will drop into the southern Great Lakes tonight, where it will start to interact with a stalled out frontal boundary that extends from Texas to New England.

Currently, the low is rather weak and has very little shower activity with it. However, the front will supply more moisture and energy to this system and rain will likely break out across the Finger Lakes by Thursday morning.

The low will likely travel a path just south of the Finger Lakes as it begins to dissipate and transfer its energy to a new system along the coast. As it does so, the Finger Lakes looks to be in a prime spot for some steady moderate rain Thursday afternoon.

The steady rain will taper to showers as the coastal low takes over. Winds will turn northerly and cold air will flood into the region. The atmosphere will still be rich with moisture and the north winds will pick up additional moisture from the Great Lakes. As a result, Friday is looking rather stormy as well, even if the precipitation is a bit more showery in nature.

I say precipitation and not rain because temperatures will be falling through the 30s on Friday. Rain will gradually mix with or turn over to snow, depending on elevation. Rain and snow showers will gradually taper off Friday night, but not before some higher elevations could see a slushy inch or so of wet snow.

As I stated in last night’s post, we had better get used to colder weather. Everything still looks on track for a prolonged period of below normal temperatures starting towards the middle of next week.
