Alert Day for heavy rain and potential flooding

OMAHA, Neb. (WOWT) On and off showers and thunderstorms are expected this morning. Heavy rain is possible at times which could lead to localized street flooding as well as some flooding of creeks and streams. A Flood Watch is in effect for the entire area. The heaviest rain is likely between 8am and Noon for the metro area. Rain will arrive slightly later and last a bit longer for areas north of the metro. We will likely see a break in the rainfall for the afternoon, but some scattered showers or even thunderstorms will continue to be possible, though not as widespread.

Wind gusts will ramp up this afternoon and evening, with wind gusts of 30 to 45mph possible, especially south of I-80. Winds may actually drop off a bit late this evening, but will increase again on Thursday as the powerful area of low pressure approach the region. As the low passes by midday Thursday, winds will sharply increase, with gusts of 40 to 60mph possible across the region. Some gusts over 60mph will be possible west of the metro, where a High Wind Watch is in effect.

After seeing a break in the steady rainfall this afternoon, more rain showers are likely overnight into Thursday. Colder air will be pushing in on Thursday, with rain likely changing over to snow. Some snow accumulation is possible west and north of the metro, where winter weather alerts are in effect. When combined with the very strong winds, the snow will likely produce low visibility and difficult travel.

Rainfall amounts around an inch are likely today. Add that to snow melt on going across the region, and that will likely be enough to cause flooding on some area creeks and streams. As all of that water dumps into area rivers, additional flooding is likely, especially along the Platte, Elkhorn, Big Blue, and Missouri river south of Omaha. Flooding on rivers will be delayed from the rainfall, and may not begin until Thursday or Friday for some areas.
