Cold Only Gets Colder…

Highlights:

  • Light snow chances
  • Frigid times
  • Bitter close to 2017

Heavy Winter Gear Required…First and foremost, we want to wish each and every one of you a very Merry Christmas and a continued blessed and safe holiday season.

The upcoming forecast period will be dominated by bitterly cold conditions.  At times, jabs of dangerous cold will penetrate into the Ohio Valley.  With arctic high pressure attempting to dominate the pattern, it’ll “out muscle” the potential of any sort of major widespread winter storm threats.  With that said, it won’t eliminate snow chances altogether and we must remain on our toes for the chances of a more impactful event over the weekend.

Beforehand, light scattered snow showers are possible late tonight into Tuesday morning as arctic reinforcements blow into town.  Two additional opportunities for snow will present themselves Thursday night into Friday morning, and, as mentioned above, just before the New Year.

Keep the heavy winter gear handy through the forecast period as Old Man Winter make his presence felt.

Upcoming 7-Day Precipitation Forecast:

  • Snowfall: 1″ to 3″
  • Rainfall: 0.00″

An “Appetizer” To Christmas Eve’s “Main Course…”

In general, northern ‘burbs picked up between 1″ to 3″ of wet snow earlier this morning before drier conditions arrived for the afternoon hours.  A couple of reports include Whitestown with 1.6″, Carmel with 2″, and Lebanon with 2.5″.  A sharp cut-off with slushy coatings to less than 1″ made it as far south as the city, itself.  Today’s event will be viewed as the “appetizer” to Christmas Eve’s “main course.”

Vigorous upper level energy will track through the Ohio Valley Christmas Eve afternoon into the evening, itself.

Snow will begin to overspread the state, especially north of the I-70 corridor during the mid-to-late morning hours and we expect a steady snow to fall across the northern half of the state throughout the majority of the day.  A period of moderate to heavy snow should develop during the mid-to-late afternoon, continuing into the evening hours across central Indiana.  Road conditions will begin to really deteriorate during this time frame as surface temperatures fall into the 20s.

Eventually, snow will end from west (around 8p) to east (around midnight) tomorrow night, but not before depositing a widespread swath of 3″-5″ for areas generally north of I-70.  For the city, itself, we think 2″ to 3″ is a good call, with generally an inch, or less across far southern portions of the state.

Don’t be surprised if enough Christmas “magic” results in localized heavier totals with potential banding that develops tomorrow afternoon into the evening hours.  All in all, this will be a classic, picturesque snow event for Christmas Eve.  Hoosiers will wake up Christmas morning with a fresh blanket of white.

We have additional wintry fun and games to track later next week!

“It’s Beginning To Look A Lot Like Christmas…”

Highlights:

  • Wet snow today
  • New snow maker for Christmas Eve
  • Turning bitterly cold

Festive Forecast…Rain changed to wet snow for northwestern ‘burbs between 4a-5a and the transition from wet to white will continue to progress southeast through the morning.  A period of heavy, wet snow will fall through mid and late morning before precipitation begins to taper off.  Our going snowfall forecast from yesterday continues to work with this event (for most it’s a slushy coating to 1″ in and around Indianapolis, increasing to a couple inches north).  We experienced our high temperature for the day shortly after midnight.

Attention will then quickly shift to a new snow maker arriving Christmas Eve.  The day will start dry, but snow will quickly develop as we progress into the afternoon.  At times, snow will come down at a moderate clip and provide a classic setting for your festivities tomorrow evening.  (We’ll have a fresh discussion posted later this afternoon for this event).  Travel safely and leave extra time to reach your destination, as snow will accumulate on roadways.  Additionally, we’ll add wind into the mix tomorrow night into Christmas Day with fresh cold air advection.

Speaking of Christmas, if you’re anticipating Santa to deliver outdoor gifts, you’ll want to plan to bundle up as you head out to enjoy the new toys.  It’ll be a dry, but very cold Christmas.

Cold will remain the weather word to sum up next week and we’ll target the end of next week for the potential next winter event.  It’s a busy, fun pattern if you like winter!

Upcoming 7-Day Precipitation Forecast:

  • Snowfall: 3″ – 5″
  • Rainfall: 0.00″

Dreaming Of A White Christmas?

A busy winter pattern is on our doorsteps and the first of a series of accumulating snow events arrives Saturday morning for central Indiana.  A cold front will settle south across the state this evening, allowing colder air to filter in.  Meanwhile, a wave of low pressure will track northeast from the TN Valley into the lower OH Valley.  This will result in more widespread moisture moving into the region overnight into Saturday morning.  On the northern periphery of this precipitation, a changeover to wet snow is anticipated.  A window of opportunity is present for a narrow, but heavy wet snow band to “thump” for a couple hours and potentially may make roads slick due to the intensity of snow within this narrow zone.  Given the setup and dynamics in play, this type of event has bust potential written all over it, but this is our best idea for a first call.

A more widespread, “uniform” (easier to forecast, as well :-)) snow event will arrive Christmas Eve.  Upper level energy will cross the Ohio Valley and combine with arctic air in place to maximize moisture production.  We expect an expanding area of snow to encompass most of the state Christmas Eve, likely becoming most widespread Christmas Eve afternoon.  With cold air in place, roads will likely get slick in spots so plan accordingly with your travels.

The hits keep coming as we progress into next week.  An additional accumulating snow event may arrive Christmas night into Tuesday, followed by a more widespread and potentially major event late next week…

More later!
