Major winter storm potential Sunday

Central Indiana is less than 48 hours away from a potentially crippling winter storm.  Though much discussion centers around snowfall amounts, we're urging viewers and readers to respect the extreme dangers of the Arctic cold that arrives Sunday night.


Computer model guidance for days now have placed Central Indiana in a favorable region for heavy snow.  That is something hasn't changed much in the latest runs today.  So at this point there is high confidence that most in the viewing area will see 8″ and at the very least medium confidence of 10″+.  Remember that storm track can change between now and then, and adjustments to totals and placement may be needed by the time the first flakes fly Saturday night.


This storm will not impact Colts fans tailgating or going home.  If you're staying downtown for the Pacers-Pelicans game, you can expect some flurries and/or light snow possibly before midnight.

However it appears the heaviest accumulation of snow will occur between the hours of 7am Sunday and 7pm Sunday… when snowfall rates my near 1″ per hour.


A strong Arctic front slams into the state by midnight Monday… dropping temps well below zero and wind chills to dangerous levels of -30 to -40+!


This air mass will have destructive potential due to the length of time spent below zero, which looks like nearly 48 hours.  This is a rare feat for Indianapolis, with only 16 days on record since 1871 with "highs" below zero.  The last time this occurred was January of 1994.

There will be little wind chill relief until Wednesday afternoon, but that's when we're staring down our next snow system.  Buckle up for a truly wild winter ride in the days to come – Sean Ash
