Much of Indiana has a slight risk of severe storms between 9 a.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 (SPC) issued at 8:36 a.m. EDT.

In Indiana, the greatest threat is damaging severe thunderstorm winds of 58 mph or greater, but meteorologists cannot rule out a tornado, especially in extreme southwestern Indiana.

Heavy rain is also possible throughout the state, as well as in Ohio and Michigan counties served by the northern Indiana NWS office.

As you can see on the map above, the slight risk area includes central, west-central, south-central and southwestern Indiana, including Lafayette, Indianapolis, Bloomington, Terre Haute and Evansville. As for the 37 counties served by the northern Indiana NWS office, the slight risk area includes only a small part of Cass County and most of White County.

Areas just outside the slight risk area, including Fort Wayne and the rest of IMO SKYWARN quadrant two, could still have strong storms with heavy rain and gusty winds that fall just short of severe criteria.

The risk of severe thunderstorms is much higher just to the south of Indiana, along the Mississippi River. That area, which includes Evansville, Ind., Paducah, Ken., Jonesboro and Pine Bluff, Ark., Memphis, Tenn., Tupelo and Jackson, Miss., and Monroe La. , have an enhanced risk of what the NWS calls “significant” damaging thunderstorms winds. The NWS defines “significant” in this case as gusts of 65 knots (75 mph) or greater.  If you have friends or relatives in that area, be sure to advise them to stay tuned to a reliable weather source throughout the day.

Out next look at today’s severe weather outlook comes when the SPC issues and updated “Day 1 Convective Outlook.” It’s due by 12:30 p.m. EDT.

A smaller but still significant portion of Indiana continues to have a slight risk of severe weather between 8 a.m. tomorrow (Mon., Oct. 13) and 8 a.m. Tuesday, according to the “Day 2 Convective Outlook” that the National Weather Service (NWS) Storm Prediction Center (SPC) issued at 1:59 a.m. EDT. As compared to yesterday’s “Day 3 Convective Outlook,” the slight risk area now includes less of northern and eastern Indiana.

The newly-drawn slight risk area (see map above) includes only four of the southwestern-most counties of the northern Indiana NWS office’s 37-county warning area; Miami, Cass, Pulaski and White.

Strong thunderstorms are possible elsewhere in Indiana, Ohio and Michigan, but those storms are not expected to be severe.

Within the slight risk area, widespread, straight-line damaging wind and a few tornadoes are the greatest threats. Any severe weather that forms in Indiana is most likely Monday night.

Our next look at the severe weather risk for tomorrow comes with an updated “Day 2 Convective Outlook” that the SPC plans to issue by 1:30 p.m. EDT today.

Most of Indiana has a slight risk of severe weather between 8 a.m. EDT Monday, Oct. 13 and 8 a.m. Tuesday, according to the “Day 3 Convective Outlook” that the National Weather Service Storm Prediction Center (SPC) issued today.

SPC meteorologists expect the main treats to be damaging straight-line thunderstorm winds of 58 mph or greater and a few tornadoes.

The greatest threat will be in the southern portions of the slight risk area (see map above), however, even if Indiana receives no severe weather, meteorologists indicate that heavy rain could pose a flooding risk.

If you think tornadoes are unlikely this time of year, remember what happened in Van Wert, Ohio in November of 2002.

Our next look at the severe weather outlook for Monday comes at around 2 a.m. EDT Sunday, when the SPC issues a “Day 2 Convective Outlook.”

A team from the National Weather Service surveyed today damage in Huntington from yesterday afternoon’s severe thunderstorm. The team found sporadic, straight-line wind damage along a three-mile path from roughly 1.5 miles northwest of Huntington to approximately 1.5 miles southeast of Huntington. Most of the damage was tree damage or structure damage caused by fallen trees. The survey team estimated the maximum winds to be 65 mph. Read their full report.

The northern Indiana NWS office has issued a preliminary report that summarizes hail and damage reports it received during this afternoon’s storms. You can find the report here.

Some marginally severe thunderstorms are popping up in north-central and northeastern Indiana this afternoon. The storms have dropped hail measuring up to .75 inches in diameter. The threat is too isolated and marginal to justify a severe thunderstorm watch, according to a mesoscale discussion from the National Weather Service (NWS) Storm Prediction Center. But the northern Indiana NWS office has issued some severe thunderstorm warnings and more are possible.
