  • Another round of April showers are expected in Northeast Missouri on Tuesday. And while rain amounts are not expected to rival those seen in the area last week, it will impact the Mississippi River’s rate of retreat, according to Thomas Spriggs, a senior meteorologist with the National Weather Service (NWS).
    “The latest data we have looks like it’s not really going to give you another crest, but what it will do is slow down your rate of receding,” he said.
    As of Monday afternoon, the river in Hannibal stood at 26.5 feet, which was down over 1 foot from the crest of 27.63 feet reached on Sunday.
    Showers were expected to move into the Hannibal area overnight Monday. The NWS’ forecast calls for 100 percent chance of showers Tuesday and a 50 percent chance of rain Tuesday night.
    “The axis (of precipitation) will be from West-Central Missouri and through Central Illinois, which is going to cross right through the Hannibal area. It looks like right now the heaviest rainfall amounts are going to be near your area. We’re looking at an inch or so,” said Spriggs.
    Communities south of Hannibal, which have been battling the river since last week, should not see another surge as a result of the latest round of rain.
    “They’re starting to crest right now,” said Spriggs of Louisiana and Clarksville. “This is going to keep them at their crest height for a little bit longer.”
    After the rain-producing system pushes east, the sky will clear for at least a couple of days.
    “Wednesday and Thursday are looking to be dry, thankfully,” said Spriggs.
    Rain returns to Hannibal’s forecast on Friday.
    “The best chances right now still look to be Friday night, but it could start as soon as daytime Friday and continue into the daytime Saturday. There’s some timing differences between the various models we’re looking at, but at least one thing they do have in common is they do seem to think the best chance will be Friday night for some additional rainfall,” he said. “But it looks like you guys (in Hannibal) are going to be right on the northern edge of the better rainfall, so it looks like it will be down river from you on this one.”
