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!
