After a fairly quiet close to the work week, a vigorous upper low will track east out of OK, across northern AR, and northeast into the Ohio Valley. In response, a surface low will develop across the MS Valley Friday night, moving northeast into OH by Saturday night. The end result will be close to a (24) hr period of steady rain, at times heavy, across all of central Indiana. Additionally, we anticipate a period of gusty easterly winds Saturday morning into the afternoon hours. Widespread 1″ to 1.5″ rainfall can be expected with locally heavier amounts across central Indiana. Meanwhile, southern and southeastern Indiana can expect rainfall totals of 2″ to 3″ with locally heavier amounts. Rainfall coverage and intensity will diminish from southwest to northeast Saturday night.
