A Flash Flood Watch remains in place for a good chunk of the Quad Cities, especially along and south of I80, through Sunday morning.
A Severe Thunderstorm WATCH also remains in effect until midnight Sunday morning for the Quad Cities.
Our afternoon has been quiet so far with areas of sunshine and a few clouds. The humidity continues to remain quite high, too, making it feel a bit uncomfortable. As instability continues to build and a leftover front remains in the area, scattered showers and thunderstorms are likely to blossom into the evening hours. The best concentration of these will initially be south of the Quad Cities, closer to Mt. Pleasant and Burlington. Through the late evening and overnight the storm threat will head further north.
While initially, a few isolated stronger storms with hail and wind will be possible, I think the bigger threat will continue to be heavy rainfall. Some localized two-inch amounts certainly look likely by Sunday morning.
We’ll see a bit of a break in the storm activity for Sunday afternoon with more storms returning by the late evening and overnight hours. Another warm and humid afternoon is likely with highs around 80.
Memorial Day still holds a good chance at seeing some strong to severe storm activity, especially in the afternoon and evening. A round of storms will likely be ongoing in the morning followed by a break for the late morning and early afternoon. A warm front will be nearby again driving the chance for severe weather by the afternoon and evening. Highs will return to around 80 degrees. The driest hours will be during the early afternoon.
Chances for showers and storms remain until Thursday when we see a temporary break from the activity. This pattern may return by the following weekend with additional chances for heavy rain and severe storms.
