Client Brief: Another Round Of Accumulating Snow On Deck; Blowing & Drifting Also To Be Dealt With…

Updated 02.09.21 @ 7:15p

Type: Impactful Wintry Weather

What: Accumulating snow

When: Late Wednesday morning through Thursday afternoon

Temperatures: 18° to 24°

Wind: NE 10 – 20 MPH and gusty

Blowing/ Drifting: Considerable  

Pavement Impacts: Plowing and salting will be required

Summary: Wednesday will dawn with quiet conditions in place but snow will arrive into central Indiana by late morning. Initially, we’re only talking about light snow into the afternoon and evening. Snow will become more widespread and heavier throughout the “heart” of central IN during the overnight hours and Thursday morning before eventually giving way to lighter snow Thursday afternoon, eventually ending from west to east. Downstate, a mix of freezing rain, sleet, and brief snow is expected, including icy travel. Once again, this will be an efficient snow producer. Instead of snow ratios of 10:1 we expect closer to 15 to 20:1 ratios (similar to that of what southern parts of the state experienced Monday). The dry, powdery nature of the snow will combine with gusty northeast winds to create blowing and drifting issues by Wednesday evening through Thursday, especially in the open country. Gusty winds will persist Thursday night even as the snow comes to an end, extending the blowing and drifting concerns.

Confidence: High

Next Update: Wednesday morning (video)

02.09.21 Weather Bulletin: “Active” Would Be An Understatement…

Updated 02.09.21 @ 8a

Keep That Head On A Swivel…Before we talk about what’s ahead, it was a snowy night across south-central Indiana. Many of the reports coming in from down that way indicate our 3″ to 5″ forecast played out quite nicely, including most common snowfall totals between 4″ and 5″ (with a few isolated heavier amounts). Thank you for those ground truth reports, friends! I know we’ve said it before, but they are more valuable than you know!

Now to look ahead. Storm systems will come flying through fast and furious over the upcoming 7-days. Scattered lingering snow showers and flurries today will give way to a steadier snow as we move into Wednesday. Meanwhile, an icy mixture of sleet and freezing rain is expected across far southern Indiana. After the 12z model suite is complete this afternoon, we’ll be back with a fresh look on expected snowfall amounts later this evening.

Friday appears to offer up a much needed one day breather from wintry systems with cold, dry conditions expected. Then our attention will shift to the weekend and threat of potentially a more significant winter storm. Guidance is trying to sort out which feature has the best chance of phasing into a more potent storm system. The GFS likes the lead wave this weekend while the European holds things off until early next week. Please stay tuned.
