Yorkers, you're not crazy to rescue your flip-flops from their dust-gathering post in the back of a dark closet.

But it's definitely too early to pull out those summer shoes to replace your snow boots.

Brace yourself.

Temperatures reached nearly 70 degrees in York County on Tuesday — not quite enough to break a 1986 record of 74 degrees, according to AccuWeather meteorologist Carl Erickson.

Before winter reminds us that it's not quite over, York County will enjoy another day of 60-degree temperatures Wednesday, said Tony Mach, a meteorological technician with the National Weather Service in State College.

Rain and thunderstorms are also possible Wednesday, he said.

But then, AccuWeather and the National Weather Service are predicting the temperature will plummet to around 15 degrees overnight between Wednesday and Thursday.

A cold front is behind the wild temperature swing, Mach said.

As Wednesday turns into Thursday, the precipitation could turn to snow. But forecasters are expecting "little to no snow accumulation," Mach said.

Thursday will be sunny but windy, with temperatures in the mid-20s, Mach said.

Gusts could be as strong as 40 mph, Erickson said.

Thursday's low temperatures could freeze any wetness left on the roads, possibly causing some treacherous travel conditions, Erickson said.

Friday's high temperature will be in the upper 40s, with an overnight low in the mid-30s.

Saturday — the day of York's St. Patrick's Day Parade — will be warmer, with a high temperature in the mid-50s, Mach said.

Then, winter will rear its ugly head once again.

Snow is possible Sunday night and Monday, Mach said.
