Another Late Week Storm…

Relatively quiet weather will be with us through the 1st half of the work week and this will allow us to focus on what’s coming down the road. A complex system will begin to impact central Indiana Thursday night or Friday morning and continue through the day Saturday.

What initially began to tip us off to this potential had to do with the positive (upper ridge) over Hudson Bay. That’s still the case this morning, but now modeling is better able to see the associate storm threat “underneath.”

The question now has to do with how organized this feature is. Should it get it’s act together, this is the type pattern that an associated storm should be able to spread heavy, wet snow from the central Plains, Ohio Valley, and into the Mid-Atlantic and Northeast (even with marginally cold air available).

There’s also the possibility the system doesn’t organize until it reaches the Mid-Atlantic region. If that’s the case, we’re only looking at mixed rain and snow showers in the Friday-Saturday time period (light rainfall amounts and little, if any, snow accumulation).

It’s a complex pattern that will require close attention over the next few days. Stay tuned. A more in-depth video update will arrive this evening.

Client Brief: Wintry Mix Arrives This Evening; Slick Travel Expected Across A Portion Of The Region…

Type: Impactful Wintry Weather

A burst of snow will move into central Indiana between 5p and 7p.

What: Coating of snow and light glaze of ice

When: This evening into tonight

Temperatures: Upper 20s to around 30° before rising into the upper 30s after sunrise

Wind: Southeast tonight 20-30 MPH, shifting to the south Saturday morning and gusting to 40 MPH before shifting to the west behind the cold front Saturday evening.

Blowing/ Drifting: Non-existent

Pavement Impacts: Salting will be required today.

An area of low pressure will track across the central Plains today into the lower Great Lakes and into New England Saturday into Sunday. An associated cold front will sweep through the region Saturday PM resulting in a return of very cold air Saturday night into early next week.

The majority of the day will remain precipitation-free across the state with a lowering and thickening cloud deck by afternoon. As our attention shifts to late afternoon and evening, an initial burst of snow will make it’s way into west-central Indiana (around Terre Haute) before arriving into the city, itself, towards 6p to 7p. For a good chunk of central Indiana, this snow will transition rather quickly to a mix of sleet and freezing rain as evening gives way to nighttime. In and around Indianapolis and northern suburbs, expect a snow/ sleet accumulation of up to 1″ followed by a light glaze of ice. Further north, snow will hang on longer as the predominant precipitation type, resulting in accumulations of 2″ to 4″. If traveling this evening into tonight, icy roads are likely across central Indiana. Temperatures will warm above freezing prior to sunrise Saturday with significant improvement expected on area roadways. This will help precipitation transition to a cold rain Saturday morning before a cold front whips across the state and sends temperatures into a nose dive Saturday evening. Gusty winds will accompany this frontal passage (40 MPH gusts) and any leftover moisture will refreeze Saturday evening resulting in patchy black ice issues on untreated surfaces.
