Poor Air Quality in Eastern WI

Weekend Outlook

A new Air Quality Advisory is in effect from Noon to 11 PM today, this time for southeast and east-central Wisconsin. Air quality is expected to reach the "Unhealthy for Sensitive Groups" (orange) level. Some areas along the immediate shoreline could possibly reach the "Unhealthy" (red) level behind the lake breeze.

A wave of shower and thunderstorm activity is expected to build into the region late tonight (after midnight) and continue into Friday morning. Storms should become more isolated into Friday afternoon, possibly rebuilding to scattered coverage Friday night before drying out into Saturday. Only 25-30% chances for a few showers or storms to redevelop Saturday or Sunday, mainly in far southern and southwestern WI. Inland high temperatures should be in the 80s each day, with lake breeze circulations providing some relief from the heat to the immediate shoreline of Lake Michigan. For Sunday, the synoptic wind field will turn east and cool off much of eastern WI. Progressively warmer and more humid conditions are expected through next week.
