The transition back to snow is underway from west to east across Central Indiana… with a quick burst expected to drop a few inches around the Indy metro before this system departs. Road conditions will continue to go downhill from here, with numerous reports of slide-offs along and north of I-70.
With temperatures steadily dropping into the mid-20s, any untreated road or sidewalk will become a skating rink.
This precipitation is convective in nature, meaning rumbles of thunder are possible and heavy snow rates (1″ per hour) are still in play. Bottom-line expect slow to dangerous driving conditions the later we work into the evening.
Adding insult to injury will be areas of fog developing that will reduce visibility. Stay safe and more updates to come
At 2:30pm all precipitation types are falling across Central Indiana, with sleet and freezing rain the flavor of choice in the Indianapolis metro area. So ice accumulations of a .10″ to .20″ becomes the concern for the I-70 corridor and snow amounts appear to be less than an inch by 8pm.
With some places not climbing to the freezing mark this afternoon, untreated roads will likely get icy… especially north of Indianapolis where there is a higher chance of staying sub-freezing.
Farther north, and especially northwest, moderate/heavy snow and sleet continue to fall over Lafayette and Kokomo…and thunder remains a possibility in this dynamic atmosphere. Areas of mostly snow will see 3″+, while cities like Bloomington, Columbus, Seymour and Bedford deal with a cold rain and temperatures elevating into the mid-30s.
11:21am radar update: convective snow/sleet heading into western Indiana with numerous reports of thundersnow in the Champaign/Urbana area. Heavy snow/sleet will accumulate quickly in Covington, Newport and eventually Lafayette.
This is an area where 3″ to 5″ accumulation are most likely this afternoon and where road conditions deteriorate quickly between now and 2pm. We’ve made adjustments to our snow/ice zone map, but still believe a quick accumulation of snow/sleet is possible in the Indy metro before a transition to freezing rain occurs.
Remember a few degrees can change conditions dramatically over any given area, and the precipitation will occur in a narrow window between now and 7pm. Nicole Misencik will have a live update at noon.
Buckle up for another wild winter ride in Central Indiana. A tricky forecast looms for Monday and poses a completely different set of challenges compared to what happened last Friday in Indianapolis. That miss was due to a northerly displacement of the expected heavy snow band…but with one precipitation type. All precipitation types are on the table tomorrow, the biggest question is where does the “mixing bowl” set up.
A Winter Weather Advisory goes into effect at noon Monday and lasts until 7pm. Areas of all snow will see 3″+ and the current thinking right now is for that to be Lafayette to Kokmo to Muncie. The Indianapolis metro is in our 2″-4″ zone, with a high degree uncertainty regarding how much sleet or freezing rain will occur. No mixing would lead to high side of snowall amounts, with lower snowfall if sleet and freezing rain become dominant precipitation type. Regardless of amounts, the intensity of precipitation and timing will make the afternoon and evening commute very slow. Plan on extra time getting home from school and work tomorrow.
There should be no issues getting to work in the morning with a quiet, but cold commute expected.
We’re anticipating a quick, heavy burst of snow to arrive in the city between noon and 2pm, setting the backdrop for messy roads into the afternoon.
Snow should depart from west to east by 8-9pm and our latest winter weather maker will be long gone by Tuesday morning.
We’re eyeing Thursday for strong storm potential as temperatures surge into the 50s. With or without strong storms, melting snow and locally heavy rain increases the threat for flooding. This taste of spring will be short in nature, and snow potential returns next weekend. Check back for updates
How about some snow to go with those roses? A quick-moving, but potent upper level disturbance has its sights set on the Ohio Valley tomorrow… with southern Indiana firmly in the crosshairs of a 3″ to 4″ snow swath.
Areas south of I-70 go under a Winter Weather Advisory beginning at 7am Friday and until 7pm tomorrow. Cities like Terre Haute, Bloomington, Columbus, Seymour, and Bedford can expect up to 4″ during that time. Travel will become a challenge by early afternoon and will require some extra time in the Advisory area.
There will be a sharp cutoff to snow amounts along and north of I-70…and it’s conceivable Indy gets less than 1″ if the system tracks farther south. So bust potential is in play for downtown. We expect very little accumulation from Lafayette to Kokomo and Muncie.
Snow arrives after 7am and ramps up by midday, with tough sledding in heavier snow pockets for the afternoon commute. Spread the word please. Another lighter snow is possible Saturday, but likely produces an inch or less. We’re still on target for a relatively impressive warm up the later half of next week. 50s look likely Thursday and perhaps even warmer next weekend, with the threat for strong storms between February 21st and the 23rd. Stay tuned.
A clearing sky, fresh snow and a wind below 15mph sets the stage for a bitter stretch the next 48 hours.
Areas in northern Indiana that remain clear longer drop well below zero tonight. But the I-70 corridor will be plenty cold Monday morning and wind chills will near 10 to 15 below around the Indy metro area. Wind chills in the northern viewing area may approach advisory criteria…regardless the cold requires your utmost attention.
Despite a good dose of sunshine, temperatures will be very slow to warm and many places struggle to climb into the double-digits.
This marks a bitter stretch that gets even colder Tuesday morning, with area wide lows of 5 to 10 below zero. Central Indiana will likely remain well below the average “low” for this time of year until Wednesday afternoon.
Temperatures modify later in the week, but chances of snow increase heading into Friday. Accumulation is possible Friday and Saturday, but much too early for anymore specifics. Long-range indicators suggest much warmer conditions next week… but the verdict is out on how long this may last. Stay tune for a potential pattern change heading into the second half of February.
If you need to shovel out your car or clear sidewalks, we’re recommending sooner than later. Temperatures drop into the low teens by midnight and at or below for many along and north of the I-70 corridor Thursday morning.
Current thinking is for only partial clearing tonight, but if a more prolonged period of a cloud-free conditions develops lows could be much colder due to the fresh snow pack. Either way bus stop conditions for kids will be less than ideal with sub-zero wind chills. Limited sun, deep/fresh snow and Arctic air keep Thursday highs a good 25 to 30 degrees below normal.
Clouds clear by Friday morning and set the stage for a low temperatures well below zero. Much of Friday is bright before our next snow-maker arrives this weekend. Current modeling indicates this will be a relatively light system, with a few inches of snow possible.
We’re monitoring the middle of next closely, as a stalled front (exactly where to be determined) and waves of energy may produce a prolonged period of snow in the Ohio or Tennessee Valleys. There is significant model divergence at this time, so confidence is low on days 6 and 7 in the forecast.
Have a great evening and thanks for reading the blog – Sean Ash
Snow rates over Central Indiana will increase quickly this evening, with one to two inches per hour expected between 5pm and 3am tonight. Road conditions will deteriorate rapidly and accumulations up to 10 inches or more are possible over a large portion of the viewing area.
The high side of the forecast seems likely given latest radar analysis, snow reports, and building atmospheric lift. Don’t be surprised if you hear thunder this evening in heavier snow bands. Even if you don’t see 10 inches of snow…the snow you do see occurs over a short period of time. Many roads will become impassable this evening, and will be flat-out dangerous.
It’s feast or famine for cities like Seymour, Bedford, North Vernon. ”If” you don’t see any mixing of sleet or freezing rain, then you’re staring down the higher snow totals. At this point it’s too tough to call. But there should be a heavy snow burst of 3-6″ this evening before any mixing occurs. We’re still not ruling out significant icing for these areas either.
