Snow And Freezing Rain For The 2nd Half Of The Weekend…
Brief: Accumulating snow and freezing rain
Forecaster: McMillan
What: Accumulating snow and freezing rain
When: Late Sunday morning into Sunday evening
Temperatures: Lower 20s rising to near freezing by Sunday night
Wind: SE to S 5-15 MPH
Blowing/ drifting: Minimal to non-existent
After a cold and quiet open to the weekend, a disturbance will overspread moisture over the top of a modifying (still cold enough for trouble) air mass as we close the weekend. Snow will likely reach Indianapolis and surrounding communities late morning Sunday, continuing into the afternoon hours. Snowfall intensity will be light with occasional moderate bursts. As relatively milder air aloft gets pulled north, precipitation will end as light freezing rain Sunday evening. While we don’t anticipate heavy accretion, a light glaze will likely be noted on top of the freshly fallen snow Sunday evening.
Confidence: Medium to high
Next Update: 5p

Pre Super Bowl Rambles: Stormy Pattern Shifts To A Return Of Significant Cold?
In the short-term, there’s no getting around the very active pattern in place. As we’ve been discussing, we’ll find ourselves “smack dab” in the middle of a battle ground between a stubborn southeast ridge and building cold to our northwest. The fight in between will yield well above normal precipitation over the next couple of weeks.
Over the upcoming (10) days, expect a roller coaster ride in the temperature department as the battle takes place. While the most anomalous warmth is taking place now (IND is on pace to set a new record high temperature before the end of the day), relative warmth will continue to dominate into midweek before colder air presses and wins out.
After Monday’s light rain, we’re targeting (3) opportunities for significant precipitation across the region:
I. Tuesday night-Wednesday (still may include a risk of freezing rain across north-central communities).
II. Wednesday night-Thursday morning
III. Thursday night-Friday morning (ending as light snow)
When all is said and done, model data is in agreement on significant rainfall totals across central Indiana (2″ to 3″ amounts will be common by Friday).
Thereafter, confidence is high on colder air returning as we close the week and head into next weekend.
Guidance suggests that we still need to remain abreast of the potential of a more widespread wintry event late next weekend and this is something we’ll continue to keep close tabs on as we progress through the upcoming week. As of now, this doesn’t appear to be a major event, but stay tuned.
As we look ahead, we’ll have to continue keeping a close eye on the MJO. Today’s update shows the majority of data swinging things into Phase 8 by mid to late month. Should that come to fruition, prospects of another significant cold spell loom large…
Fun times ahead- no matter how you look at it! 🙂
Enjoy the game!

Winter Storm Update: Significant Impacts Still Expected Later Today…
While the “1st half” of the storm certainly has been a challenge, we still anticipate a high impact situation to develop this afternoon into tonight across the region.
Our updated snowfall forecast:

Late Friday Night Update…
A significant winter storm is on our doorstep and will begin to impact all of the region in the coming hours. Low pressure will continue to deepen as it moves northeast out of Oklahoma, Arkansas, and into Kentucky. As this takes place, copious amounts of moisture will lift north into central Indiana. We think precipitation reaches Indianapolis, itself, during the overnight (likely between 3a and 4a).
The bulk of the northern half of the state is still expected to receive predominantly snow with this storm. However, things get much more tricky along the I-70 corridor (10 to 20 miles either side) as temperatures will be “marginal” early on in the event (aloft and at the surface) and will lead to quite the headache for the first several hours of this storm. Even as of this update, confidence is low on precipitation type for the I-70 corridor, itself. A difference of half a degree (F) can mean a world of difference with precipitation type (snow, freezing rain, sleet, or rain). Admittedly, concern is growing for the potential of icing in this area before the deeper cold air can arrive and switch things over to snow. On the other hand, should precipitation rates be heavy enough, it’s certainly possible these heavier rates will cool the entire column of air quicker than high resolution modeling currently suggests and a quicker transition to snow would result. “Boom or bust” potential is higher than normal along the immediate I-70 corridor.
Given the above, and the potential of a “deformation band” of snow to develop during the 2nd half of the storm, our forecast snowfall totals remain unchanged.
Stay tuned and please know we’ll have another update posted Saturday morning.
The other big concern here is the fact that east-northeast winds will turn increasingly strong and gusty as the day gives way to afternoon and evening. Winds may gust as high as 40 to 50 MPH at times during this time period as the storm heads off to the northeast. Even if you accumulate an inch of snow, expect blowing and drifting issues to result. Combine that with rapidly falling temperatures Saturday evening and the stage will be set for slick and hazardous travel throughout the region.
Much more in a few hours around this storm and additional “fun and games” that await next week… (Please send coffee ;-)).
