We’ve Seen This Before…
Updated 02.20.21 @ 8:29a
Before we dive into the challenges late next week, the potential is still very much alive and kicking for a period of slick conditions to develop Sunday evening/ night. While we’ll likely be in the middle 30s during the majority of the time this light precipitation is falling, the concern remains, given the duration and magnitude of the cold air (ground is now reported frozen “8 to 12”), that any liquid precipitation that falls will freeze on untreated area roadways and sidewalks. If you have travel plans Sunday night, plan to give yourself plenty of extra time.
Light rain should arrive between 8p and 10p (west to east across the state) Sunday before ending as a bit of light snow (little to no accumulation expected as of now). Total precipitation should be 0.20″ or less for most with this event.
As we look ahead, the next item of possible trouble awaits for mid and late week. A cold front will push south of the area Wednesday night into Thursday morning. While this may generate a brief period of light rain transitioning to light snow, it’s what follows that’s of more interest.
Operational guidance (both the European and GFS) suggest this late week system will present a winter storm for our friends in the TN Valley, but we advise to tread with caution for now.
The reason? A strongly negative PNA.
You know the drill by now. This should lead to a more stubborn southeastern ridge and subsequent further north storm track.
Over time, I’d suspect we’ll see just that- the models trending further north with this particular storm system.
As it is, ensemble guidance is already significantly further north than their respective operational counterparts. At the very least, another interesting case study is in front of us…
Stay tuned!

02.18.21 Weather Bulletin: Another Snowy Day…
Updated 02.18.21 @ 8:38a
More Shoveling Ahead…Widespread snow continues to blanket central Indiana and this will remain the case through early afternoon. Throughout immediate central Indiana, reports indicate we’ve already seen 2″ to 3″ for most and we’ll likely tack on an additional 1″ to 2″ before the steady snow exits early afternoon. (Please keep those reports coming by sending to us via Twitter @indywx or email bill@indywx.com. As always, your ground-truth reports are invaluable- and greatly appreciated)!
“System” snow will diminish from southwest to northeast this evening and arctic reinforcements arrive on the scene tonight and Friday. Additional snow flurries and scattered snow showers are a good bet Friday, but with minimal additional accumulation.
As high pressure builds overhead Friday night and Saturday morning, we’ll likely “go low” on the thermometer and rival numbers seen around these parts Wednesday morning. Sunshine and just enough return flow around that area of high pressure will go a long way to helping us out Saturday afternoon though as we forecast a “balmy” 30° ;-).
Our next storm system will blow through here Sunday into Sunday night. You know our concern. Despite forecast model data trying to warm things up, I’m afraid data still isn’t understanding the situation at hand, especially given the prolonged nature and magnitude of the cold. We’ll continue to keep a close eye on things, but as it sits now, I’m still very much concerned we’re looking at more of a wintry mix/ icing type event Sunday PM as opposed to a cold rain the majority of data currently shows.
Next week will open on the milder side of things, but we’re already eyeing the next possible round of wintry “mischief” late next week…
More on all of this, including a longer range update later this evening in our video discussion.
