Widespread life-threatening flash and urban flooding will continue to pose a significant threat to life and property in south-central Texas. Catastrophic fiver flooding, with rapid rises on small streams, arroyos, and typically dry washes, is expected.

Overview
|
A surface low tracking northeast across southern Wisconsin brought widespread wintry precipitation to central and southern Wisconsin on February 22nd, 2023. Across central Wisconsin, precipitation remained primarily all snow during much of the event, while southern parts of Wisconsin saw accumulating sleet and freezing rain. Freezing rain resulted in icing reports from 0.10'' near Dodgeville, Wisconsin to 0.75'' near Burlington and Franksville, where Ice Storm Warnings were in effect. Racine, Kenosha, and Walworth counites were hit particularly hard. The combination of 0.50 to 0.75'' of ice accumulating on trees and powerlines, and strong winds throughout the duration of the event led to numerous power outages. Some of these power outages lasted for 1 to 2 days.
