Bursts of moderate snow are possible as the front passes between 7 and 10 p.m., snow will taper off late tonight. Locally snowfall of .5” to 1.5” is possible.  A winter weather advisory has been issued for northern Indiana for snow and blowing snow.

ARCTIC FRONT ARRIVES TONIGHT

What a cold wave we have coming!  The low early Wednesday morning dipped to a frigid -2° in the city, coldest in 2 weeks but several stronger pushes of cold are on the way.  The next arctic front in the series passes the city tonight, between 7 and 9 p.m.  Winds shifting to the northwest will signal the change and through the night temperature will be in free-fall.  Winds will strengthen and gust over 25 miles per hour through much of the day on Thursday and those stronger winds combined with temperatures that dip again below zero will send the wind chill to -15° to -30° by Thursday morning.  There isn’t much of a recovery by Thursday afternoon with temperatures holding at 0 to 5 above.

A wind chill advisory has been issued and in effect from 1 a.m. Thursday morning through the Friday morning commute.  Dangerous wind chill of -15° to -30° are possible Thursday, with a wind decrease not expected until mid-Friday morning.

COLD WAVE UNDERWAY – COLDEST AIR STILL COMING

The frigid pattern locks in to end the month to start February.  With 62 percent of the days this winter below normal – the next two weeks will remain well below normal.  The coldest air is still coming with potentially cold air to equal the frigid temperatures from early in the month.  A 16-day breakout of temperature averages from normal highs could be as cold as 25 to 30 degrees below normal!  Several more nights of subzero temperatures are coming.  By early Tuesday morning next week the low could dip to -14° in the city.
