Snow Update And Looking Ahead Towards Mid-March…

Snow will overspread central Indiana through the late morning hours into the afternoon.

While the overall idea where the accumulating snow would fall was a good one from early week, our initial expected amounts won’t come to fruition. The reason? The storm system is much weaker and faster moving than originally modeled.

Accordingly, this is a 1″ to 2″ type event for most of the area. The majority of the snow will fall from noon to 5p.

A period of snow will scoot across central Indiana from late morning into the early evening hours.

This same storm system will be responsible for a severe weather outbreak, including the possibility of a couple of strong tornadoes, across the Deep South this afternoon.

Back here on the home front, MUCH colder air will pour into the region this evening, remaining in place into the new work week. Back-to-back nights with lows in the upper 0s to lower 10s can be expected across central Indiana Monday and Tuesday mornings.

This is all part of the overall colder than normal first half of March, powered by the SOI crash (several week ago), deeply negative EPO, and MJO rumbling through the cold phases.

Additional storm dates to keep note off include Thursday night into Friday (more of a wintry threat with the 3/7-3/8 system) and Saturday into Sunday (potential strong thunderstorms with the system on 3/9-3/10).

Looking ahead, it still appears the mid-March warm-up is on track as the EPO flips to positive.

With that warm-up will also come a return of heavier precipitation events and a continued overall active storm track across the region. Precipitation looks to run above average for the mid-month stretch.

We’ll dig deeper early week on what lies ahead as we close the month of March and look ahead towards April…

All-Access Client Brief: Morning Thoughts After Looking Over The Latest Data For Sunday…

Brief: Accumulating snow

Forecaster: McMillan

What: Accumulating snow

When: 6a to 6p Sunday

Temperatures: Upper 20s to near 30

Wind: North 10-20 MPH

Blowing/ Drifting: Minimal to moderate

Right off the bat, there’s no need to make any changes to our ongoing snowfall forecast. Snow will arrive into south-central Indiana before sunrise Sunday before expanding northeast through the morning hours, including Indianapolis by mid-to-late Sunday morning. Greatest potential of embedded heavier banding continues to look like it’ll lie across south-central parts of the state (thus the continuation of a 3″ to 5″ swath of snow). North winds will turn gusty Sunday evening and a bit of blowing/ drifting is possible on east-west roadways Sunday night as the late season arctic air arrives in earnest.

All-Access Client Brief: Latest Thoughts Around This Weekend’s Snow…

Brief: Accumulating snow

Forecaster: McMillan

What: Accumulating snow

When: Late Saturday night into Sunday

Temperatures: Upper 20s to lower 30s

Wind: North 5-15 MPH

Blowing/ Drifting: Minimal

Overnight model trends are in overall better agreement, but still present notable differences- not only with the track, but overall strength and forward motion with the system. Saturday will be dry before clouds increase, lower, and thicken Saturday evening with snow overspreading the southern half of the state overnight. Mainly light to occasionally moderate snow (downstate) can be expected into the daytime on Sunday. The overall quick movement of this storm system will ultimately be a limiting factor in accumulation totals. Behind the system, much colder air will pour into the area Sunday night and Monday (single digit low and highs in the upper 10s to lower 20s).

Confidence: Low-medium

Next Update: This evening in video format
