Good morning! There have been some adjustments to today’s forecast, with the wintry mix that was anticipated in southern Indiana now looking to track farther north into the state as we go through this afternoon and evening. Chances arrive in Indy after 3pm, coming in just in time for the evening commute. Temperatures will hover just above freezing for most of this, falling near to slightly below freezing as it moves out by mid-evening. Roads will be wet to slushy in spots, with isolated slick spots possible tonight. The ground may whiten with a dusting to a localized near 1″ of snow especially along I-70 and south. Light flurries even make it as far north as Kokomo and Fort Wayne. There could be some patchy freezing drizzle lingering south through just after midnight, but do anticipate conditions to dry out overnight, with the risk of residual moisture refreezing. Wind will not be very strong to help dry pavement fast, so that will be a concern.
Given the temperatures, model output is likely overdone with snowfall totals vs. reality, but I think across central and south-central Indiana scattered coatings to localized 1″ on grassy/elevated objects.
Friday through Saturday, the overall forecast remains risk free, with the chance of a spotty flurry/sprinkle Friday night.
The main focus is on Sunday. Right now snows look to arrive just before sunrise Sunday, then moving out late Sunday evening. The peak of the event occurs during the day Sunday. Heaviest over the southern half of the area, lighter snows north.
Thinking the heaviest snow risks (3-5″+) in the purple shaded area across the southern half of Indiana. Snow is looking rather likely even across northern Indiana, but snows will be lighter. I do think within the purple area there can be a band of 5″+ setting up.
As you can see on the map below, there are still some differences regarding the track of this storm. Overall, the risks to this forecast is for more of a southerly tick given the strong arctic high coming down. While a tick north is still possible, that seems less likely given the extent of arctic high pressure coming down. Any north shift will have a limit.
