3 p.m. update A freeze watch has also been issued for Thursday morning, from midnight to 8 a.m.
10 a.m. update: Up to an inch of rain could fall in the York County area today.
And the National Weather Service is warning that the rain could come in the form of thunderstorms accompanied by 40 to 50 mph winds.
A cold front is also moving into the area, prompting a freeze warning to replace the freeze watch the weather service put into effect Monday afternoon.
The warning runs from 2 a.m. to 8 a.m. Wednesday, with temperatures expected to dip into the mid-20s.
The weather service still says there's a chance of snow tonight, but no accumulation is expected.
The NWS is also warning that areas of frost are possible Wednesday and Thursday evenings.
Update: Cold, stubborn winter just won't let York County escape its grasp.
There's a 50 percent chance the area will experience snow late Tuesday, according to Tony Mach, a meteorological technician with the National Weather Service in State College.
But, Mach said, "There won't be any accumulation."
York County can expect a high temperature around 60 degrees Tuesday.
Then, a cold front will move into the area, bringing rain with it, Mach said.
In the evening, that rain could turn into snow, he said.
Overnight Tuesday, temperatures will plummet to the mid 20s, Mach said.
The weather service issued a freeze watch for York County from 2 a.m. through 8 a.m. Wednesday.
Temperatures will begin to creep back up Wednesday and Thursday, but patchy frost is possible both nights.
There's a chance of rain Friday night and Saturday, Mach said.
But, there's no reason to expect that rain will freeze to snow, he said.
