Type: Flooding and Severe Weather; North-Central IN Wet Snow

What: Heavy rain and severe weather; north-central Indiana heavy wet snow

When: Friday, 3/3/23

Wind: Variable 20-30 MPH with gusts to 50 MPH

Summary: A deepening area of low pressure will track into the central Ohio Valley as we close the work week. This will lead to an expanding area of heavy precipitation through the overnight and into Friday morning. Precipitation will fall in the form of heavy rain across central portions of the region, including the Indianapolis area, along with a flood threat. Further north, heavy wet snow will develop across northern IN, into the greater CHI area and into central MI. Note: Early 00z guidance is shifting this area of low pressure further southeast which puts more of north-central parts of the state in play for wet snow accumulation Friday afternoon. We’ll continue to monitor overnight trends but the possibility is there that the rain-snow line will have to shift south compared to what most of the data has been showing the past couple of days. Widespread rainfall amounts of 2”+ can be expected into central IN along with non-thunderstorm gusts of 50+ MPH.

We bracket the 1p to 4p window for the threat of severe storms. This risk lies from Indianapolis proper and points south. We anticipate a line of storms to “bow” out, leading to an elevated damaging wind threat across southern IN during this time period but we also note the potential of a couple of quick spin-up tornadoes within this line of storms, as well. It’ll be important to have a means of getting any and all warnings Friday. Keep tuned to local media or have a way to receive the latest National Weather Service updates. All of the “action,” including the heavy rain threat is expected to wind down Friday evening, including much calmer and quieter conditions returning Friday night.

We’ll be back with a fresh video discussion no later than 7:30a Friday.
