Two Weekend Snow Events…The morning is off to a sunny, frosty, and frigid start with middle teens for many central Indiana communities.  Mid and high level cloudiness will stream into the region through the afternoon before lowering and thickening towards evening.  An area of light snow will then overspread central Indiana towards 6-7 o’clock.  This won’t be a huge snow event, but a dusting to less than 1″ will fall, especially along and north of the I-70 corridor.  This will be just enough to make for slick travel in places as you head out to church Sunday morning.

The second snow maker will be the more significant one.  Upper level energy will dive south out of the Plains states tonight and help ignite surface low pressure over the lower Mississippi River Valley Sunday morning.  This area of low pressure will then lift northeast and track up along the western slope of the Appalachians into Monday morning.  This will spread accumulating snows northeast into our region as early as Sunday evening, continuing overnight into the wee morning hours Monday.  Our initial snowfall forecast (posted below) places most of central Indiana in a 2-4″ swath of snow from this event, but we caution this still isn’t etched in stone.

Fresh arctic air will pour into the Mid West and Ohio Valley region Monday evening into Tuesday…  That Tuesday morning expected low isn’t a typo, BTW :-).

Bitter Feel And Periods Of Snow Showers…Waves of upper level energy will dive southeast and serve to provide two things: reinforce the cold/ arctic air and provide periods of snow showers.  Gusty northwest winds will also accompany the waves of cold air.  All-in-all, plan on a wintry week ahead!

Questions Concerning Late Next Week…Forecast models are struggling on the details, but we still think a storm system will deliver the chance of snow or a wintry mix of rain and snow late next week.  Details to come in the days ahead.

50/50 Split On Sunday Night Snow…

Quick-hitting Bullet Points:

  • Light snow Saturday night
  • Still questions around Sunday night snow potential
  • Even colder air invades early next week
  • Fun and games continue in the longer range

The afternoon model suite is in in it’s entirety and it leaves us with about as many questions as answers :-)…

Four of our more trusted short-term forecast models are split 50/50 on the outcome Sunday night.  In the snowy camp you have the NAM and European.  In the drier camp you have the GFS and GEM.  Past experience with this type event says the European and NAM solutions may have the better handle and we think the drier modeling will shift a touch northwest with time over the upcoming 24 hours.  The difference between camps would be a nice 2-3″ type snowfall for the Monday morning commute across central Indiana versus nothing more than a few flurries.  More as the details become clearer…

We still forecast light snow to overspread central Indiana Saturday evening and night.  While this won’t be a big deal, a dusting to 1″ of snow is a good bet across most of central Indiana, especially from the I-70 corridor and points north.  Roads may be slick in spots on your way to church Sunday morning.

One thing that’s a certainty is that another blast of arctic air will invade along with scattered snow showers early next week.  This push of bitter air will be even colder than this weeks.

In the longer term, plenty of wintry “fun and games” remain.  In fact, today’s 12z European has the look set to offer more meteorological headaches come late next week.  Ah, the season is only beginning… 🙂

Mid November Or Mid January?!

Snow showers continue to track down the I-65 corridor this evening. Don’t be surprised of a quick dusting of snow for portions of Boone County over the next hour. Short…
