01.27.21 Weather Bulletin: Snow Builds In This Afternoon For The Southern Half Of The State; Keeping Close Eyes On The Weekend…
Updated 01.27.21 @ 7:51a
No Rest For The Weary…A fast moving area of low pressure will scoot east this afternoon and evening. This will spread a swath of light to moderate snow across the southern half of the state in the 1p (west) to midnight (exiting southeastern portions of the state) window. While still primarily a light event, models have “beefed up” snow amounts ever so slightly with this system over the past 24 hours. Our snowfall forecast for system #1 can be found below.
Colder air will pour in for all during the overnight and should be just enough to kick up some lake-generated scattered snow shower activity into Thursday morning.
Weak high pressure will then build in and supply a sunny close to the work week. You enjoy the sun and briefly quieter weather and let us worry about the weekend!
Speaking of the weekend, this is the period that continues to look increasingly likely to produce the most impactful winter storm of the season for our immediate area. We forecast early sun to quickly give way to a lowering and thickening cloud canopy Saturday (the sky will have the looks of a snow storm brewing by lunch for most). Precipitation will then overspread the region from southwest to northeast as we progress through the afternoon. The potential is there for a heavy wet snow thump Saturday PM before precipitation transitions to a wintry mix as low pressure scoot by just to our south. Before that transition, “several” inches of wet snow is looking increasingly likely. As colder air wraps back around into the region, wrap-around moisture will fall as light snow and snow showers into early next week.

Heavy, Wet Thumping Ahead For Northern Indiana: Updated Snowfall Forecast…
This unseasonably cold pattern was bound to produce a couple of additional wintry challenges (at the very least) before all was said and done, and this week isn’t disappointing. Guidance today has continued to trend snowier for northern parts of the state, and we fully expect periods of heavy, wet snow to begin falling across the northern 1/3 of Indiana tomorrow evening, continuing into Friday morning before eventually ending during the afternoon.
Snow will likely reach peak intensity around sunrise Friday morning, including 1″ to 2″ per hour snowfall rates. With the unseasonably cold air in place, we expect road crews to have to activate the plows as the snowfall intensity, combined with time of day will make a mess of area roadways across northern Indiana.
The snow will begin to diminish from west to east during the late morning and into the early afternoon Friday, but not before dumping several inches on the region. Our updated snowfall forecast is below. We’ll be back early in the morning with a fresh video update. Have a relaxing evening!

Reviewing Saturday’s Snow And Looking Ahead To Another Busy Week…
Snow moved in during the predawn hours Saturday across north-central Indiana before encompassing more of central Indiana as the morning progressed. By mid-late morning, an incredibly intense band (2″+/ hour snowfall rates) set-up shop just north of Indianapolis. This was a byproduct of strong frontogenesis and dynamic cooling. Speaking of frontogenesis, if interested, here’s a fantastic article that can explain things further.
The end result was an “overachieving” wet snow event across north-central Indiana, including as far south as the northern Indianapolis ‘burbs. Sleet made it as far south as Greenwood before precipitation ended Saturday evening.
While the placement of our accumulating snow zone was a good one, amounts of 4″ to 5″ were reported throughout the southern half of this 1″ to 2″ forecast zone. This morning’s snowfall analysis shows the narrow, but moderate stripe of wet snow through the state:
As the sun rises and clouds begin to depart, that snowpack is showing up on this morning’s visible satellite image.
Officially, Indianapolis recorded 1.2″ Saturday, but as noted above, areas just north received as much as 4″ to 5″. With that increasing March sunshine today, snow will be all but a distant memory by later this afternoon. The average high for March 15th is in the lower 50s. Most will be 5° to 7° colder than that today with mid 40s for most.
As we turn the page and look ahead to what the remainder of the week will provide, a weak cold front will sweep through the Ohio Valley Monday night and Tuesday. This will be a moisture-starved frontal passage with only scattered, light showers anticipated tomorrow evening/ early Tuesday.
Things then turn much more unsettled as we head into the second half of the week. An initial wave of moisture will result in a period of moderate to heavy rain Wednesday. This will be followed up with a round of thunderstorms Thursday PM into early Friday morning. Some of these storms may reach strong to severe levels and will require us to continue to closely monitor things throughout the week.
Widespread 2″ to 2.5″+ rainfall amounts can be expected by the time everything winds down Friday afternoon. Most of that will fall Wednesday and Thursday night/ Friday morning.
We’ll dry out next weekend, but shift to a much colder time of things (lows in the 20s and highs in the 40s). This will come as a rather rude shock after highs Thursday flirt with the 65° to 70° mark.

Client Brief: Threat Of Impactful Wintry Event Increasing As Southeast Shift Continues…
Type: Impactful Wintry Weather
What: Accumulating snow and wind
When: Wednesday into Thursday morning
Temperatures: Middle 30s falling into the middle 20s by Wednesday night
Wind: North 15-25 MPH, increasing to 25-40 MPH Wednesday night and gusty
Blowing/ Drifting: Moderate to significant by Wednesday evening, continuing into Thursday morning
Pavement Impacts: Salting and plowing likely will be required
There has been a significant shift in the majority of model data today regarding the track of our midweek storm system. This has to do with a variety of elements, but most notably, the fact that the upper level energy at one time thought to come together to result in one primary storm during the first half of the work week, now looks to come in two parts: Monday into Tuesday, followed by a separate storm Wednesday into Thursday (this was what at one time was illustrated by the models a week+ ago). The debate now will continue for the next 24 hours around the deepening Storm #2 goes through, and this will have significant impacts on what central Indiana experiences in the Wednesday through Thursday time period. We think an initial wave of low pressure will organize along and just south of the Ohio River Tuesday night before tracking northeast and strengthening along the way into the eastern Great Lakes by Wednesday night. Should this, indeed, be the case, moisture would become widespread (after a relative “lull” Tuesday evening) across central Indiana Wednesday morning. With cold air funneling into the area by this time, the predominant precipitation type would fall as snow across central Indiana, including Indianapolis. Initially, this would be a wet type of snow before transitioning to a more powdery nature Wednesday evening.
As the storm begins to deepen to our northeast, blowing and drifting snow would become a concern on west-east roadways Wednesday evening into Wednesday night as the pressure gradient increases. By this time frame, north and eventually northwest winds would gust over 30 MPH with temperatures falling through the 20s. “System” snow would come to an end Thursday morning, but lake effect will continue across the traditional primary Snowbelt of northern Indiana (please note the amounts above do not account for the additional lake effect snow that would fall for Laporte, St. Joseph, and Elkhart counties). Additional lighter snow is a good bet for all as we close the work week out Friday, courtesy of upper level energy diving southeast across the state.
One additional note: We’ve been receiving a lot of questions around whether or not the southeast shift will continue with the model updates tonight. While some slight additional southeast movement in the axis of heaviest snow is still possible, there will be a limit due to the interaction between the deepening surface wave and area of high pressure. We will continue to keep a close eye on the data overnight and update things accordingly if needed early tomorrow morning.
Confidence: Medium
Next Update: Tuesday morning
