FIRST SIGNIFICANT SNOW FALLING

The first area-wide snowfall is underway in central Indiana Monday afternoon and evening. As temperatures continue to fall, the light rain turned to snow in Indianapolis just before 2 pm. By 4 p.m., a half inch of snow was reported at the airport, marking the first measured snow since March 30.

UPDATE (8 p.m.): Indianapolis has set a record snowfall for the date of 2.3". The previous record for November 11 was 1.2", set in 1995 and 1932.

A Winter Weather Advisory is in effect overnight and snow ends and bitter cold takes hold.

Some lake effect snow bands will likely extend into northeast central Indiana through sunrise, producing some slick spots well after sunrise.

SNOW IS A LITTLE EARLY

Is this snow early? On average, the first measurable snow in Indianapolis will fall around the 22nd of November, so yes, it is a little early. The earliest measured snow is October 18. Last year, our first measured snow came November 14.

ARCTIC BLAST

A full blown cross polar jet stream is delivering a bitter early-season blast of arctic air. As first forecasted over a week ago, the second surge of arctic air will be more bitter and threaten many cold record temperatures early in the week.

The temperatures have dropped sharply after 60-degrees on Sunday. By 5 p.m., temperatures had fallen well below freezing, nearly 30-degrees colder. Add a north wind at 15 mph and gusting, it feels like it is in the teens.

This is a formidable early-season arctic blast delivering low temperatures into the middle teens early Tuesday morning and challenging a record that has stood for 108 years. The record low of 14-degrees was set in 1911.

The cold will back off but not until another potential record low early Wednesday morning, with many locations dipping into the single digits by sunrise. The current forecast of 9-degrees will break the record 10-degrees, set in 1986.
