Another mild day is on tap with a southwest flow ahead of a frontal boundary that slips through this evening with light showers. Note the sharp temperature gradient this evening.…

As mentioned below, bust potential was/ is high with today’s forecast. The further north trends in the NAM and GFS will ultimately trump the normally reliable Canadian and European solutions. As such, slushy snowfall accumulations will be light (1″-2″) for the city, itself, increasing to between 2″-5″ for northern Indianapolis suburbs (Zionsville, Carmel, Westfield, Noblesville, etc.). Double digit totals will fall across the northern third of the state.
For the most part, snowfall accumulations will come from this area of precipitation moving through the region.
Heavy wet snow will likely fall for a period of time, especially from northern portions of Indianapolis and points north late morning into the early afternoon.
Temperatures will then likely creep up a few degrees through the mid afternoon hours before falling this evening. Snow will mix with, or change to, snow across central regions this afternoon with the northward track of the low. Note the stark temperature contrast across the region this evening.
The week will get off to a cold start as highs Monday only top out in the lower 20s. Enjoy your Super Bowl Sunday and keep the reports coming!

The initial surge of moisture has, for the most part, come and gone- dropping one half to one inch of snow for many across central Indiana. Overnight computer model data…

An incredibly difficult and challenging forecast is in store for central Indiana over the course of the next 24-36 hours. I want to get out front with this right from the get go: bust potential is high with this type set-up, as a jog 10-20 miles north or south of the surface low will mean the difference between half a foot of snow and plain cold rain. As it stands now, and after careful consideration of every piece of data available, here’s our updated snowfall map:
I still am not sure any one piece of data is handling the interaction between the arctic high to the north and the developing low to our southwest “perfectly.” As such, additional fine tuning will have to take place tonight. That arctic high is powerful at nearly 1045mb. From a meteorological standpoint, it’ll be a fascinating battle watching the fight play out.
As you can see, we’re going to be looking at a very tight thermal gradient and it, unfortunately, appears to set itself up directly over the I-70 corridor. Precipitation type and amounts are the biggest challenge within the I-70 corridor. Further north, confidence increases rather significantly for a crippling snow storm. For central Indiana, this will be a very wet and heavy snow event before ending as a drier, powdery snow on the back end. As winds increase Sunday afternoon/ evening, the heavy “paste” like snow won’t blow around as easily as it would if it was drier. Further north the snow consistency will be drier and blowing and drifting will be severe (in the 8″-12″+ zone).
In the shorter-term, rain and a wintry mix will arrive into the region as early as early as 6-7 o’clock.
Stay tuned. Another post will hit here late tonight (midnight-ish). In the meantime, we’ll keep our thoughts coming at @indywx through the afternoon.
