Client Brief: Heavy, Wet Snow Arrives Saturday Evening…

Updated: 01.29.21 @ 7:38a

Type: Impactful wintry weather

What: Accumulating snow

When: 4p Saturday – 4a Sunday

Temperatures: 29° to 32°

Wind: SE 10 – 20 MPH and gusty

Blowing/ Drifting: Considerable

Pavement Impacts: Plowing and salting will be required

Summary: Saturday will likely start off with early morning sunshine before a lowering and thickening cloud canopy rolls in through late morning. By early afternoon, the sky across most of central IN will have that classic look of a snowstorm brewing, and rightfully so. The initial band of snow will arrive mid to late afternoon (we bracket 4p to 5p into Indianapolis, itself) and will hit like a wall. The combination of evaporative cooling, strong lift, and embedded banding features will likely result in S+ (heavy snow) throughout the evening hours across central Indiana. This will be a wet, heavy snow. Most of central Indiana should remain snow throughout the night, the exception being areas on the south side of the city (line from Greencastle to Greenwood to Greensburg) and points south where temperatures may creep just above 32° and result in a brief mix before transitioning over to rain. Drizzle or mixed rain and snow showers Sunday will transition back to snow showers throughout the afternoon, but the majority of accumulating snow across our region will fall in that 12 hour period from 4p to 4a Sunday.

Confidence: High

Next Update: This afternoon (video)

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 should overspread northern Indiana Thursday evening- most likely between 8p and 10p.

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.
