Scattered showers will spread across central Indiana at times through the day. Most of this rain will be light in nature through the afternoon hours, but a couple of moderate showers are also possible.
A surface low will track east across the lower Ohio Valley tonight and this will result in more concentrated heavy rain falling across the southern portion of the state this evening into early Monday morning. This is a bit further south than model guidance suggested yesterday. Additionally, a couple of strong thunderstorms are also possible tonight across far southern Indiana.
It wouldn’t surprise us to see the Storm Prediction Center (SPC) include portions of southern Indiana in a ‘Marginal’ or ‘Slight’ risk of severe weather tonight with future updates.
With the more southern track now expected from this storm system, the corridor of .50″ to 1″ rainfall totals will settle across the southern portions of Indiana, with 0.10″ to 0.25″ expected for central Indiana on average.
Rain will come to an end for all of the state by mid to late morning Monday with dry conditions returning Monday evening into the middle of the week, thanks to high pressure.
Dry and pleasant conditions will remain in place through the daytime hours Thursday before a storm system approaches Thursday night into Friday. The gusty southwesterly air flow in advance of this storm will help pull warmer conditions northeast into the Ohio Valley. Highs between 65-70 are on tap by Thursday afternoon. Unsettled weather is anticipated to remain through next weekend along with progressively colder conditions.
