While the rain may have subsided for now, flooding remains a significant concern for much of the viewing area tonight. The last of the rainfall exited the region just after dawn, but many roads remain covered by water, making travel for some rural communities difficult or even dangerous.
While Benton County was under a Travel Warning earlier today, they since have been downgraded to a Travel Watch, the same White County. During a Travel Watch only essential travel, such as to and from work and emergency situations, is recommended.
On top of that, many rivers and creeks continue to rise at this hour; in fact, the Wabash River in Lafayette won’t crest until early Thursday afternoon. Currently sitting at 21.9’, when it does crest, it will have reached 23.5’; that’s just two feet below major flood stage.
In addition to water-covered roadways, another dose of rainfall and possibly wintry precipitation is expected to arrive overnight; as a result, the National Weather Service has issued a Winter Weather Advisory for the southern half of the viewing area between 11:00 P.M. ET and 10:00 A.M. ET Thursday. Freezing rainfall could make for a slick Thursday morning commute is some areas.
Following tomorrow morning’s scattered rainfall and wintry weather, the afternoon and evening appear as though they will remain primarily dry. That begins to change however, after midnight Friday morning. A weak low passing to our north will generate scattered rain showers through Friday morning.
Unfortunately, the rain doesn’t stop there; the first hints of our next round of potentially significant rainfall will reach our westernmost counties after 10:00 P.M. ET Friday. A core of low pressure swing northeastward from the Great Plains across the Great Lakes will supply the region with sustained rainfall through at least 8:00 A.M. ET Sunday.
Current projections indicate that Greater Lafayette may receive anywhere between 0.30” of rainfall across our northwestern counties to as much as 3” of precipitation throughout our southernmost portions of the viewing area! As of right now, Lafayette stands to receive around 2” of additional rain between Thursday and Sunday.
