Briefings
From the Forecaster
Heavy Rain Potential this Afternoon & Evening
Created by the NWS La Crosse WFO
Additional rounds of moderate to heavy rainfall occur this afternoon into tonight. While widespread heavy rain is expected towards east-central Iowa and far southern Wisconsin, confidence in the extent and impacts of the rain begins to decrease as one travels further north and west. However, there have been some trends in the forecast that would support renewed thunderstorm development as far north as I-90 later this afternoon, which is farther north that earlier forecast. Rainfall amounts with these northern storms could still easily reach 2-3 inches, but these higher rainfall totals will be more scattered in nature. Bottom line, much of the area is saturated and additional rainfall, even a small amount, can lead to renewed flooding concerns. Stay weather aware this afternoon into tonight!
