Rain Saturday
A weak, disorganized storm system will impact the Finger Lakes this weekend with rain and possibly some thunder before ending as snow on Sunday.
Temperatures ahead of this system have risen into the 40s and low 50s Saturday morning.
Precipitation will overspread the area from west to east during the second half of the morning and persist through the early afternoon.
As this happens, colder air will seep in from the west, with temperatures returning to the 40s for the western Finger Lakes this afternoon. Areas further east will remain in the 50s into the late afternoon.
The area of rain that moves through will be widespread with some gaps between individual showers. Therefore, between about 11am-4pm, it will be raining most of, but not all of the time.
For areas from Cayuga Lake and east, a couple of thunderstorm cells could develop within the area of rain. These thunderstorms would be limited to some heavier rain, a couple of occasional lightning strikes, and perhaps a little pea-sized hail. Most areas will not see any of this, though.
Precipitation will become more scattered after 4 pm and should begin to mix with and change to snow around midnight.
Snowy Sunday
Moisture wrapping around the backside of this system will result in widespread precipitation moving back into the Finger Lakes by Sunday morning.
Much of Sunday will have precipitation as the system only slowly drifts away.
Some of this precipitation will be rain or a rain/snow mix, but it appears that snow may end up being the primary precipitation type on Sunday.
Higher elevations could even see some of this snow stick, especially in the morning and late in the day. A couple of inches on grassy surfaces is not out of the question for these areas. Roadways should remain just wet, though.
Temperatures will be in the 30s most of the day, but some late warming will work into the western Finger Lakes with temperatures in the 40s.
Rapid Turn Around
Some showers or flurries may linger over Central New York early Monday before sunshine and south winds take over.
A large high pressure system will build into the Southeast, placing the Finger Lakes and most of the eastern United States in a strong warming pattern.
Temperatures Monday could start to approach 60 degrees, especially over western areas that see more sun.
Tuesday will soar into the mid 70s while Wednesday, a mere three days after our Sunday snow, could approach 80 degrees.
Temperatures will remain above normal into the end of the week as a storm system approaches, bringing the chances for an increase in humidity resulting in showers and thunderstorms.
