It's official - although you probably could have guessed it anyway.

January-March 2015 ranks as the coldest first three months of the year in history for Lancaster County, according to Millersville University Weather Center data.

So it's only fitting that the last day of March comes with an expected daytime high - 50 - that's 9 degrees below normal.

It's also supposed to rain off and on today, according to Accuweather.com. North of Lancaster County, snow is expected.

Millersville meteorologist Eric Horst on Monday declared this January-March the coldest in the 101 years for which weather records have been kept in Lancaster County.

Combined, those three months averaged 7.1 degrees below the normal temperature here.

Individually, January was 4 degrees below normal, February was 11.3 degrees below normal and March was 6 degrees below normal.

This year's 7.1-degree average below the normal temperature follows last year's 6.9-degree variation below average, which was the third coldest, three-month start to a year on record.

So in two years, Lancaster County saw two of the three coldest first three months of the year of the past century.

In keeping with that theme, Accuweather predicts that when the clouds blow out around midnight tonight, the temperature is really going to drop.

Accuweather is calling for the mercury to hit 28 before sunrise Wednesday, which would be 8 degrees below the normal low for April 1.

Wednesday should be sunny, but it's still going to be cold, with a high of only 49 expected. That's 10 degrees below normal.

Temperatures should dip below freezing during the night yet again, before the warm-up begins Thursday. 

A high of 64 is expected Thursday, under mostly sunny skies, followed by a high of 67 Friday, which should come with some rain.

That warm spell should blow away Saturday, when a high of 48 is expected, followed by a high of 52 on Sunday.
