All-Access Client Brief: Stripe Of Accumulating Snow Streaks Across Central IN…

Brief: Accumulating Snow

What: Accumulating snow

When: Thursday afternoon into Friday morning

Temperatures: Upper 20s to near 30

Wind: E 5-10 MPH

Blowing/ Drifting: Non-existent to minimal

Snow will develop to our northwest tomorrow night into Thursday morning before streaking southeast across central Indiana Thursday afternoon into Friday morning. The heaviest snowfall is expected to occur Thursday afternoon into the evening hours with lighter snow falling Thursday night into Friday morning. Despite what should be moderate intensity at times, the higher March sun angle should help with accumulation on area roadways (still expecting slick and slushy travel at times during periods of heavier intensity) and the idea here is that a general 1″ to 3″ swath of snow falls in a northwest to southeast orientation during the period. Temperatures should remain fairly steady or slowly fall into the upper 20s and winds are expected to be light.

Confidence: Medium-high

Next Update: 7a Wednesday

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

All-Access Client Brief: Plowable Snow Moves In Overnight…

Brief: Heavy Snow & Sleet

Forecaster: McMillan

What: Heavy Snow & Sleet

When: 12a to 8a Wednesday

Temperatures: Upper 20s to lower 30s

Wind: E 15-25 MPH

Blowing/ Drifting: Moderate before mixing with sleet

The setup remains the same as a warm front lifts north during the overnight. Copious amounts of moisture will arrive into central Indiana and with cold air in place, a period of moderate to heavy snow will develop. Timing into the city, itself, should come around, or just before, midnight. While the snow will be of the heavy, wet variety, gusty easterly winds will result in blowing and drifting snow (especially on north-south roadways) before precipitation transitions to sleet. We’ve “beefed” our accumulation forecast up to include a 3″ to 5″ band across east-central Indiana, including Indianapolis, as short-term guidance is indicating a period of significant “forcing” (or lift in the atmosphere) that will lead to heavy snowfall rates before the transition to sleet. A couple of hours with snowfall rates in excess of 1″ per hour will likely be observed in that 1a to 3a window. Precipitation will transition to sleet and a period of freezing rain between 3a and 5a from south to north, before turning to all rain in the city before sunrise. Further north, a transition to rain won’t be noticed until after 8a, but the majority of precipitation will likely be over with by that point (just lingering drizzle and fog).

Confidence: High

Burst Of Snow Transitions To Sleet & Freezing Rain Before Ending…

A burst of snow will move across central Indiana during the predawn hours (a few hours earlier than guidance suggested). Precipitation will become more widespread late morning into the early afternoon hours and as milder air aloft arrives on the scene, light snow will transition to sleet and freezing rain before ending. Further north (Kokomo to Ft. Wayne), precipitation is expected to remain all snow where 1”-3” will fall today before ending. Highs will top out around the freezing mark later this afternoon before falling into the middle 20s tonight. A few slick spots may develop on area roadways.

Much more later this morning on the week ahead and what looms further down the road as we wrap up the month.
