Dusting to a possible inch on Friday with heavier amounts missing from central Indiana west, south and east.
The latest data from the Live Doppler Weather Center 13 continues to point to more “harmful” snow Friday through Friday night in central Indiana. Which means for many areas accumulations will be less than an inch (with the exception of the northwest and south-southeast) but sufficient at times to create slippery roads…especially Friday night after the temperatures have dropped.
Winter weather advisories and/or a winter storm watch are in place all around central Indiana…indicating where more impactful travel conditions are emerging with this system.
At this time the air remains relatively dry and we expect this to “eat away” some of our potential snowfall over the next 24 hours. That said, a narrow patch of snow is expected to develop north-northwest of Indianapolis later tonight through Friday morning. This will be the first of two snow/precipitation spells in the viewing area…and will provide most of the forecast snowfall for the 1″-3″ zone in north-northwest Indiana .
Light snow/flurries will be possible around Indy Friday morning, but at this time we don’t expect major travel issues for the metro area on Friday.
The second wave of precipitation (snow/rain combination perhaps) develops late morning through early afternoon and will be most concentrated along/south of I-70. But it will fall on surface temperatures in the low/mid 30s, which should keep roads wet only where it happens. Temperatures drop below freezing near sunset Friday and there could be heavier snowfall rates developing over southeast Indiana as the storm system begins to strengthen.
The location of this potential strip will be critical as it would have a higher chance of producing 1-3 inch roads and slippery roads. After reviewing the latest data, we keep this area southeast of Indy with a wide dusting area at locally 1″ over the central part of the state.
It is conceivable that the two bits of morning and late afternoon/evening energy can mostly bypass the central parts of the state…producing only a dusting or less.
Either way, we don’t expect any major problems, but you’ll definitely want to check the conditions before heading out on Friday evening, as untreated surfaces will become slippery where it’s snowing as bitter air blows in. state… setting the stage for -5 to 5 wind chills on Saturday morning.
A biting north-northwesterly wind is also bringing lake effect snow showers/bands to the central/eastern part of the state.
The warmer southwesterly wind on Sunday provides a quick climb with highs in the 50s to end the weekend. Check back for updates.
