Mild and showery midweek for FLX

A stalled out boundary will keep occasional light rain showers around the Finger Lakes Tuesday and Wednesday before the front moves through as a cold front on Thursday.
A stalled out boundary will keep occasional light rain showers around the Finger Lakes Tuesday and Wednesday before the front moves through as a cold front on Thursday.

The middle of the week is looking a bit showery, but mild, across the Finger Lakes.

Southwest winds from the Ohio Valley are converging with west winds over southern Canada and northern New York to fuel a boundary that is acting like a stalled out front. While the air south of this boundary is mild, the air just to the north isn’t exactly chilly, either. The true cold air is locked further north over Canada.

This boundary will sit in this general location, draped from west to east across Lake Ontario, throughout Tuesday and Wednesday. It will likely wobble north and south a bit, sometimes pulling the showers out of the Finger Lakes, while pushing the main band into the area at other times. Generally speaking though, the northern Finger Lakes will see more shower activity than the southern Finger Lakes.

Outside of the band of showers, some sun may come out, helping to boost temperatures even higher across the Southern Tier. Some of those areas could see the mid or even upper 60s over the next couple of days. Further north, highs should be mostly in the low 60s.

The on and off showers will continue into Wednesday evening. On Thursday, a storm system moving across Canada will pick up this boundary and force it through the Finger Lakes as a cold front. Showers will become more widespread for a time, but should depart by the late afternoon or evening hours.

Cooler air will work in, with lows dropping back towards the upper 30s and low 40s Friday morning. Despite some sun on Friday, highs will only reach the mid to upper 40s. Some 50s will return for the weekend, along with some more showers Saturday night and/or Sunday.
