Isolated strong or even damaging wind gusts are possible in north-central and northeastern Indiana and southwestern Lower Michigan  overnight, according to a mesoscale discussion that the National Weather Service Storm Prediction Center (SPC) issued at 8:26 p.m. EDT. The SPC does not expect to issue a watch, however, because the overall threat is too low.

The loss of daytime heating has resulted in insufficient atmospheric instability to support widespread severe thunderstorms.

Meanwhile, a tornado watch remains in effect for parts of central, southern and extreme northwestern Indiana.

A larger part of Indiana has a slight risk of severe thunderstorms, according to an updated “Day 1 Convective Outlook” that the National Weather Service (NWS) Storm Prediction Center (SPC) issued at 3:45 p.m. EDT.

As compared to the SPC’s midday update, the latest outlook extends a slight risk area to include north-central and northwestern Indiana and part of northeastern Indiana. The outlook covers the period from 4 p.m. EDT today to 8 a.m. EDT tomorrow.

The slight risk area now includes all of IMO SKYWARN quadrant three and Huntington County of quadrant two.

The greatest threat is damaging straight-line thunderstorm winds of 58 mph or greater, but meteorologists cannot rule out a tornado.

People in the slight risk area should keep a reliable source of weather warnings accessible through the night and SKYWARN storm spotters should prepare for possible activation.

The SPC will next update its severe weather outlook for today and tonight by 9 p.m. EDT.

Much of western and southern Indiana continue to have a slight risk of severe weather between 12:30 p.m. EDT today and 8 a.m. EDT tomorrow, according to an updated “Day 1 Convective Outlook” that the National Weather Service (NWS) Storm Prediction Center issued at 12:34 p.m. EDT.

The main changes since the previous convective outlook are:

1. Removal of the “significant” damaging wind risk.
2. Expansion of the moderate risk area eastward to cover more of Mississippi and part of Alabama.

In most of the counties served by the northern Indiana NWS office, strong storms remain possible, with a heavy rain threat. But as of the time of this writing, the risk of a severe storm in that area is very small.

The SPC plans to update its convective outlook again by 4 p.m. EDT.
