Wintry Forecast; New “Plowable” Snow Event Arrives Monday…

Highlights:

  • Sleet changes to snow
  • New snow and wind maker Monday
  • Bitter air returns

Double Shot Of Impactful Winter Weather…A mixture of sleet and freezing rain will begin to transition to snow from west to east as we progress through the late morning into the early afternoon.  We don’t have any significant changes to our snowfall forecast (remember this doesn’t include the freezing rain and sleet accumulations that have led to travel issues this morning already).  Embedded snow bands will likely result in enhanced snowfall rates into the early afternoon across central Indiana.

Precipitation will end for all except southeastern portions of the state by mid-to-late afternoon and then we’re left with the “clean up” from round one.  Saturday and most of Sunday will feature dry and very cold conditions.

Our attention this weekend will then shift to a potent clipper system that has eyes on central Indiana late Sunday night into Monday.  Snow will overspread the region during this timeframe and given the nature of this event, heavier, more intense snow bursts are also expected to accompany the fresh arctic air that will drill in here Monday evening.  This will be an impactful event not only from the new falling snow, but from problems that wind and drifting will bring, along with a new batch of sub-zero temperatures.  Our snowfall forecast Monday hasn’t changed since yesterday, including widespread additional amounts of 2″ to 4″.

Dry, but bitterly cold conditions return for the mid and late week stretch.

Upcoming 7-Day Precipitation Forecast:

  • Snowfall: 3″ to 6″
  • Rainfall: 0.00″

*Please note the 7-day precipitation forecast outlined above is for Indianapolis proper.

Growing Concern For Significant Ice Event…

Just wanted to touch base on some of the latest data this evening and concern is growing around an extended period of freezing rain and sleet that will develop within a few hours, continuing through the morning rush for the majority of central Indiana.  Some of our high resolution data is suggesting significant amounts of freezing rain overnight- in some cases more than one quarter inch across southwestern and central portions of the state.  This is enough to create concern for the potential of downed tree limbs and power lines in spots.

Forecast radar (time stamp at 4a below) shows widespread freezing rain developing during the overnight, including the greater Indianapolis area.

The model finally suggests that freezing rain will begin to transition to sleet around the morning rush hour.

An icy mixture of sleet and freezing rain is expected to transition to snow late morning into the early afternoon hours across the region.

We suggest ensuring you charge your electronic devices and cell phones tonight in the event you lose power overnight or Friday morning.  We’ll hope for a faster transition to sleet and snow than data currently suggests, but the concern is certainly present this evening for an impactful ice storm for portions of southwestern and central Indiana.

The morning commute Friday will be heavily impacted and if you don’t have to travel we recommend remaining indoors.

Ice Transitions To A Double Shot Of Snow; Frigid Times Return…

Highlights:

  • Bye-bye thaw
  • Ice to snow Friday
  • Second snow maker Sunday night

Active Forecast Period…A breezy southerly flow will dominate our weather today ahead of an approaching cold front.  Showers and unseasonably mild conditions can be expected today.  (Despite the snow lover in me, I will admit that it’s been mighty nice being able to jog outside without worrying about slipping on ice or snow the past couple days).

Things begin to change in rather dramatic fashion tonight as the cold front presses through the state and allows much colder air to “ooze” back into central Indiana.  At the same time, a wave of energy will track northeast along the cold front and help spread more widespread moisture into the colder air at the surface.  We expect rain to begin mixing with and changing to an icy mixture of sleet and freezing rain after midnight across western and central portions of the state, and closer to 5a-6a across eastern Indiana.  Eventually, as the entire column of air cools, icy precipitation will transition to snow.  If the sleet to snow transition occurs faster, snowfall totals will be at the higher end of the first call numbers outlined below.  Should sleet hold on for a longer period of time, snowfall amounts will be on the lower end of forecast totals.  We think snow will end around noon west of the city, but steady snow will hang on much longer across eastern sections of the viewing area- well into the evening hours.

Here’s our first call snowfall forecast for Friday.  While this doesn’t include freezing rain amounts, we think a glaze up to 0.10″ is a good bet – especially on elevated and exposed surfaces.

Dry conditions will return Saturday along with a much colder feel.  Quiet times won’t last long as another snow system will quickly begin to impact the state Sunday evening into Monday.  Widespread steady snow is expected to develop and will actually be a more uniform, bigger, event for most of the viewing area.  We’ll add in wind and arctic air which will lead to blowing and drifting issues as the day progresses Monday into Tuesday.  Here’s our first call for additional snow amounts Sunday evening-Monday.

The forecast period will wrap up dry and bitterly cold.  With a fresh snowpack down, it’s safe to say we’ll add at least another night to the sub-zero “club!”

Stay tuned, friends!

Upcoming 7-Day Precipitation Forecast:

  • Snowfall: 3″ to 6″
  • Rainfall: 0.25″ to 0.75″
