Cold Sunday…Fresh off celebrating our snowiest winter on record (surpassed last night at IND at 51.6″ and the Record Event Report can be found here), we’ll enjoy a dry day, but blowing and drifting snow will remain an issue in the open country. A few breaks in the cloud cover can be expected this afternoon on what will otherwise be a rather cloudy day.  Highs will only climb into the lower to middle 20s (well below the average high of 40 and closer to the normal low of 24).  Yes, our cold, snowy winter just keeps on keepin’ on!

Snow And Ice Issues Monday…A storm system will move through the region Monday and deliver a mixture of precipitation types across central Indiana.  The way we see things unfolding as of this forecast update brings a wintry mix of sleet and snow into the city around noon with periods of moderate to even heavy wintry precipitation falling into the mid to late afternoon hours before we begin to see the shield of moisture push northeast.  This will be a “thump and go” type event.

As for precipitation type, this remains a challenge and will require much fine tuning later tonight and through the day tomorrow (another now cast scenario).  We’re thinking mostly snow is the dominant form of precipitation from the northern suburbs of Indianapolis and points north.  Here, 2-3″ of wet snow is possible, polished off with a light glaze of a freezing rain/sleet mixture before precipitation ends.  For the city, itself, we think around 1-2″ of snow is possible with a glaze of freezing rain of around a tenth of an inch. Farther south, to include the southern Indianapolis suburbs, an icy mixture of sleet and freezing rain will be the concern with glaze potential approaching one quarter inch.  Again, we caution this is our best idea at this point and we’ll post some fresh thoughts later this evening.

Needless to say, tomorrow stands to include treacherous driving conditions in and around central Indiana and the National Weather Service will likely issue Winter Weather/ Freezing Rain Advisories later this afternoon to account for the wintry conditions anticipated tomorrow afternoon.

Flooding Concerns On The Rise…With such a deep snowpack across central Indiana, combined with a frozen ground, flooding concerns will be on the rise as early as the middle to latter part of the week.  We think dry and chilly (albeit milder) conditions will be with us Tuesday, but low clouds, fog, and drizzle likely develop by Wednesday as milder air streams north over the snowpack locked in across the region.

By Thursday, our attention turns to the potential of heavy rain and a couple of thunderstorms as a cold front blows through the region.  Early ideas of Thursday rainfall numbers would suggest anywhere from .50-1″ of rain is laid down and when combined with the heavy snow pack and milder air, flooding concerns will certainly be present.  Needless to say, if you live in a flood prone area, please monitor the situation closely later this week.

Winter Blows Back In…As promised, the briefly milder shot of air would be just that- brief.  We continue to monitor data that suggests a colder, more wintry, pattern blows right back into the region to wrap up February.

Accumulating Valentine’s Day Snow…The Canadian led the charge and other modeling has followed suit.  The region will deal with accumulating snow Valentines Day as low pressure moves southeast out of Missouri into the Tennessee Valley.  We think snow will fall at a good clip, periodically heavy, and begin around mid morning around the city.  In fact, a strip of 2-5″ of snow is likely to be laid down between Indianapolis and Louisville later today.  Latest radar trends from upstream and banding features suggest snowfall amounts may reach 6″ along the I-70 corridor. Needless to say, if you have travel plans this afternoon plan for snow covered roads and slick travel.

A fresh shot of arctic air will drill south into the region tonight and result in Saturday “wake up” temperatures in the single digits with a biting northwest wind.

Another Fast Moving Clipper…After a mostly dry Saturday, we forecast light snow to build back into the region Saturday night into early Sunday.  This will only be a light snow event and most amounts will be in the dusting to 1″ category.  The sun should quickly return Sunday afternoon, though it’ll remain colder than normal.

Foggy Start To The Week…As a southerly air flow transports milder air north and over the snow pack across central Indiana fog will develop.  It’s possible some freezing drizzle is dealt with Monday morning before temperatures rise above freezing.  Prepare for a downright gloomy start to the work week.  A cold front will push through the region Monday evening and lead to a period of showers, potentially transitioning to light snow or a light wintry mix Monday night as cold air sweeps back in.

A Spring Tease…A spring tease will have many Hoosiers wanting to break out the shorts by the mid week period.  In fact, highs will zoom into the 60s Thursday, courtesy of a strong and gusty southwest breeze.  The downside?  A line of showers and gusty thunderstorms later in the day.  While we still have a week to monitor this situation, the possibility is there for a few storms to reach severe levels across the Ohio Valley region.  Stay tuned as we monitor this developing weather situation.

Looking longer term, we anticipate the briefly milder spring “tease” to be just that.  Signals are increasingly favorable for a prolonged period of cold, wintry conditions building back into the region as we put a wrap on February and head into March.

Initial Snowfall Ideas; No Let Up In Sight With This Pattern…

As we approach the time for many Super Bowl parties to kick off, we wanted to go ahead and post some initial snowfall numbers for our upcoming winter storm Tuesday afternoon into Wednesday.  It’s important to note that model data will be able to fully sample the storm later tonight so we’ll fine tune things Monday morning, but here’s our early idea…

We think snow (wintry mix across south-central Indiana) moves in as early as Tuesday afternoon, with the period of heaviest precipitation falling Tuesday night into the wee morning hours Wednesday.  This will be a quick moving storm and, as such, will impact precipitation totals from reaching even higher amounts.  Additionally, we’re also noting the chance central and southern Indiana gets into the dry slot late Tuesday night into Wednesday morning.  As of right now, our forecast snowfall totals are based on 1. a relatively fast moving storm system and 2. the current likelihood of being dry-slotted across portions of central Indiana.  It will be important to note where the all-too-popular (for snow lovers) deformation zone sets up shop as heavier snow totals, in excess of half a foot, will likely fall within this band.  Additionally, an icy mixture of sleet and freezing rain may fall across south-central Indiana (current thinking places this icy mix south of I-70) and this could lead to tree limb and power line damage in spots.  Stay tuned…

Here’s what area radars may look like Tuesday night into Wednesday morning.  This data is courtesy of the fine folks over at Weatherbell Analytics.

Our thinking hasn’t changed on the overall track of the low (track map originally posted here Saturday night).

Quick Bullet Point Thoughts:

  • Snow will overspread central Indiana Tuesday afternoon
  • Heaviest snow will fall Tuesday night- where it remains all snow 4-6″ is our initial call
  • An icy mix of sleet and freezing rain could lead to significant ice accumulations down state (greater than 0.25″ ice accumulation)
  • Closely monitoring the forward motion of the storm and potential dry slot working into the region late Tuesday night-Wednesday morning

By the way, we’re tracking another winter storm for the upcoming weekend and we’ll discuss this in more detail in the days to come… Enjoy the game!
