OMAHA, Neb. (WOWT) - A Severe Thunderstorm Watch is in effect for southeastern Nebraska until Midnight. This watch does not include the metro area at this time. A cold front pushing into the area is expected to cause strong to severe storms to develop south of I-80 this evening. A few of those storms could produce damaging hail. However coverage of severe storms is not expected to be widespread, so not everyone will see severe weather. The strong to severe storms will push to the southeast of the area after 10pm, with the severe threat tapering off by Midnight. However, additional rounds of showers and general thunderstorms are expected to move in late in the overnight, lasting into Sunday morning. This will maintain a heavy rain threat across southeast Nebraska and southwest Iowa where a Flash Flood Watch is in effect through Sunday morning. 1 to 3 inches of rainfall may lead to localized flooding across this area.
Rainfall Sunday morning should taper off by midday, with partly to mostly cloudy skies remaining through the afternoon. Temperatures will be much cooler than the past few days, with highs only in the lower 70s. A few areas may only see highs in the upper 60s! Skies should clear out Sunday night allowing temperatures to fall into the mid to low 50s by Monday morning.
The first day of Fall will feature plenty of sunshine and pleasant conditions, though temperatures will still be above normal with highs near 80. We warm a bit more on Tuesday with highs in the lower 80s. Another push of slightly cooler air should arrive for Wednesday and Thursday with highs in the mid 70s. Despite the cool down, those temperatures are also above normal for this time of year! More storm chances enter the forecast by Thursday night, lasting through at least Saturday morning.
