A storm system moving into the Great Lakes will produce windy conditions and a little precipitation for the Finger Lakes.
High pressure over southern New England will help lock some dry air in place over the Finger Lakes. Even as moisture from the storm system moves east, this dry air will help counteract the influx of moisture. The result will be spotty precipitation at most for Wednesday, and only a modest increase in the chances for rain Wednesday night.
The best chance for showers will be early Thursday morning. Heavier rain will develop during the day on Thursday, but mostly over eastern New York and into New England as a new low pressure center forms. For the most part, the Finger Lakes will miss out on substantial precipitation from this system.
Temperatures, however, will improve a little bit thanks to this system. High temperatures should rise to around 40 degrees on Wednesday, with little drop overnight. Thursday will be almost normal, with highs near or just above 50 degrees. The normal high for this time of the year is in the low to mid 50s.
This system will also bring some gusty winds, especially later Wednesday into Wednesday night. Some places could gust to 40 mph.
The low that develops on Thursday will stall out on Friday. Cold air and moisture will wrap around the back side of this system and into the Finger Lakes. Temperatures will only be in the mid and upper 30s with widespread rain and snow showers.
These should clear out in time for the weekend, though a few flurries from another system on Saturday and from lake effect Saturday night will be possible. Temperatures will remain cold through the weekend before returning to the 40s with some rain early next week.
