Overnight storms to target southern Indiana
Despite a reprieve from the heavy rain, flooding remains a concern for all of central Indiana. There is more heavy rain potential overnight and it's beginning to appear this round "may" have the most impact along and especially south of I-70.
Latest radar analysis (note image time is 7:53pm EDT) shows a linear feature erupting west of St. Louis. Due to heavy rain from earlier today, and significantly cooler air in northern Indiana, this feature will most likely target the "best" atmospheric instability… which currently resides along and south of the Ohio River. While extreme southern Indiana has a higher chance of damaging wind, increasing atmospheric lift overnight (and ample moisture) keeps flooding rain very much in play.
We believe the southern half of Indiana has the highest chance of seeing another 1-2″ of rainfall, including Indianapolis. Locally higher 3″+ totals are a possibility in south central Indiana if the modeled "training" of storms comes to fruition. Please have a way to receive weather warnings, as much of this will take place while most are sleeping.
Friday begins balmy in the 60s as overnight temperatures hold steady. Expect mild conditions to prevail into midday but the passage of a cool front will deliver a different feel Friday afternoon, with temperatures dropping into the 40s. One constant tomorrow will be wind! Gusts may near 45mph and sustained wind will be in the 20-30mph range.
We're still expecting a relatively bright weekend with highs in the lower 50s Saturday and near 60 Sunday… though morning lows will be quite chilly near 30 degrees. The next round of rain arrives Monday and another inch is looking likely area wide.
Long range indicators suggest our first 70-degree day could be on tap next Thursday…just in time for the Indianapolis Indians home opener. Stay weather aware overnight.
