Flooding Threat Continues in Portions of Texas; Poor Air Quality in the Great Lakes through the Mid-Atlantic

Widespread life-threatening flash and urban flooding continues in south-central Texas, with considerable flooding impacts possible across central Texas. Wildfire smoke is impacting air quality across much of the Great Lakes region into southern New England and the Mid-Atlantic. Monsoonal thunderstorms may produce isolated to scattered flash flooding across the Southwest into the Great Basin. Read More >

The Air Quality Advisory remains in effect until 6 PM CDT this evening generally along and east of a Fond du Lac to Janesville line, for Unhealthy Air Quality levels due to wildfire smoke. Southwest winds will push the lingering smoke out of the area this evening and overnight. However, more smoke is expected to return to southern Wisconsin Saturday afternoon. Higher concentrations of smoke are expected Saturday evening and may linger into Sunday. The Wisconsin DNR is forecasting at least levels that are considered Unhealthy For Sensitive Groups for southern Wisconsin Saturday evening. Those in sensitive groups, such as people with lung and heart disease, take more breaks and make outdoor activities shorter and less intense. Healthy people should consider limiting their time outdoors.
Warm and humid conditions will linger into Saturday, until a weak cold front moves southeast through the area. Heat index values in the 90s to around 100 degrees are forecast in far southern Wisconsin Saturday. Widely scattered showers and storms may occur into early this evening. There are chances for showers and storms with the weak front Saturday morning along and south of I-94. Cooler and less humid conditions move in behind the front later Saturday afternoon into Sunday. However, smoke is also expected to move back into the area during this period.
