More information, including our live, interactive radar, is available in our weather section.

The National Weather Service has issued a Flash Flood Watch, in effect through Sunday morning at 6am. For the Effingham area, this will mainly be a rain event, now with 1.5-3 inches of rain possible. The heaviest rain is expected Saturday and Saturday evening, and may include isolated thunderstorms. As the advisory from the National Weather Service below indicates, already wet ground from the fast-melting snow, combined with the heavy rainfall expected will create flooding situations, especially in low-lying and flood-proned areas. Clay county remains under an additional Flood Warning until 12:30pm Saturday afternoon.

North and west of our region will be significantly different. Freezing rain and snow will be common across areas north and west of I-55.

Here's the latest from the National Weather Service in Lincoln:
