Overview
|
During the afternoon and evening hours of September 21st, a few rounds of strong to severe thunderstorms developed. The first round of storms developed north of a warm front with a weak upper level disturbance as warmer air and moisture returned to the region. Storms in the Eau Claire area pushed out an outflow boundary that traveled southward across much of the forecast area and provided an additional focus for storms. Meanwhile, by mid afternoon, a warm front was lifting north toward Rochester and Prairie Du Chien with temperatures warming to around 90, while the outflow boundary limited the high at La Crosse to 80 degrees. A few of the storms along and north of the outflow boundary produced 1 to 2" hail and damaging winds. Heavy rainfall also occurred. Storms that developed along the outflow produced some 1.0" to 3.0" rainfall amounts. Additional rainfall fell overnight and into the morning of the 22nd across Clayton and Grant Counties as the upper level trough pushed through, upping their rain totals in a band from the southwest to northeast. |
