Additional Snow Overnight; Dangerous Cold Grips The Region…

Highlights:

  • Blowing and drifting issues
  • Snow returns late tonight
  • Prolonged stretch of severe cold

Bundle Up; Snow Returns Overnight…Yesterday’s snow event went as planned and many Hoosiers are waking up to several inches of powder this morning.  The winners yesterday stretched from Frankfort to Elwood to Winchester with a 6″ to 7″ band of snow.  All of that fresh snow will be blown and drifted about today with strong and gusty northwest winds.  If your travels take you into the open country, plan on significant blowing and drifting and leave extra time to reach your destination.

Additional upper level energy will scoot across the region late tonight into early Sunday and this will help kick up an area of light snow for central and southern portions of the state as we head into New Year’s Eve.  With the arctic air mass in place, don’t be surprised if we squeeze a quick inch out in spots.

Otherwise, the big story is the prolonged nature of this severe cold.  At times, wind chill values will drop to more than 30° below zero through early week.  Take the frigid conditions seriously.  Reinforcing arctic air will pour in here late next week and lead to scattered snow showers along with a bitter feel after slight midweek “moderation.”

  • Snowfall: 1″ to 3″

Plowable Snow Event Gives Way To Dangerous Cold…

A quick-moving, but efficient clipper system will scoot across the Ohio Valley as we wrap up the work week and head into the weekend.  This will spread a swath of accumulating snow through central and northern IN this afternoon into early Saturday morning.

We forecast snow to start flying for the city, itself, around 1p to 2p.

Snow will then encompass most of the state as we progress into the late afternoon and evening hours.

At times, we expect moderate snow to be falling across central Indiana and this will, unfortunately, make for a messy evening commute.  Plan for snow covered and snow packed roads and slick conditions.  Leave extra time to reach your destination.

While snow showers will continue Saturday morning, most of the accumulating snow will fall before sunrise Saturday and here’s our updated accumulation forecast:

Attention once to Saturday will shift to the problems associated with blowing and drifting snow as winds increase and temperatures tumble.  Strong and gusty northwest winds will continue into early next week and not only will this lead to continued issues with blowing and drifting, but will also drive dangerously cold air into the area.

Here’s a look at our forecast lows over the next few mornings:

  • Saturday morning (12.30.17): 13° (falling through the day)
  • Sunday morning (12.31.17): 4° below zero
  • Monday morning (01.01.18): 6° below zero
  • Tuesday morning (01.02.18): 10° below zero

Not only will we have to deal with an extended stretch of subzero lows, but winds will combine to add further danger to the extreme weather.  Most of central and northern portions of the state will have to deal with 25° to 35° below zero wind chill values Tuesday morning.  Plan and prepare now.

Accumulating Snow Friday; Dangerous Cold Develops Next Week…

Highlights:

  • Accumulating snow on the way
  • Frigid times remain
  • Dangerously cold next week

Snow And Major League Cold On Deck…A weak impulse of energy will track across the region today and will be just enough to ignite a couple of snow showers and scattered flurries.  For most, this won’t be a big deal.  A more impactful opportunity for accumulating snow will arrive Friday as a clipper system moves southeast.  Snow will develop late tonight across the Plains states before expanding in overall coverage and intensity as it pushes southeast into the Ohio Valley Friday.  With such cold air in place, snowfall ratios will be higher than the standard 10:1 and snow will quickly accumulate on roadways, making for slick travel Friday afternoon into the evening.  Here’s our current snowfall forecast for Friday:

Snow showers will taper off Saturday morning and give way to a blustery, bitter day.  Temperatures will fall through the day and wind chill values will turn dangerous Saturday afternoon and evening (10° to 20° below zero).  This arctic intrusion will set us up for a frigid close to 2017 and open to 2018.  In fact, we expect severely cold conditions early next week (double-digit below zero readings, including wind chill values approaching 30° below zero at times).  Plan and prepare now.

Upcoming 7-Day Precipitation Forecast:

  • Snowfall: 2″ to 4″
  • Rainfall:  0.00″

Snow Chances; Cold Only Grows Colder…

Highlights:

  • Frigid times
  • Snow chances return
  • Bitter open to 2018

Serious Cold…Arctic high pressure has settled over the region and combined with our snow cover to produce the coldest morning around these parts in a couple of years.  Some across central Indiana are awaking to double digit below zero readings.  Even the slightest breeze coupled with these bitterly cold readings creates dangerous conditions to spend time outdoors.

Cold is here to stay.  In fact, we’ll only grow more bitter next week.  If we can put snow down between now and then, there’s a good chance we’re not even cold enough early next week with forecast temperatures.  Speaking of snow, we’ll have to keep close tabs on impulses of upper level energy late tonight into Thursday for the potential of overachieving in the snowfall department (similar to what the I-70 corridor experienced Tuesday).  With arctic air in place, it doesn’t take much to get snow going.

We’re still expecting a more widespread snow event over the weekend.  We’re targeting Friday night into Saturday for light snow to overspread the region and this will setup a frigid close to the year and open to 2018.
