After a chilly start today, we'll see a warm-up commence over the next few days with temperatures peaking well into the 70s to around 80 degrees on Saturday. Periodic shower chances will also accompany the warm-up. Sunday's weather is shaping up to be pretty decent for Mother's Day with dry and breezy conditions, and seasonably cooler highs in the 60s.
A passing disturbance will bring a chance of showers (20-40%) today through early this evening, mainly for parts of E Iowa and NW Illinois. Isolated lightning is possible. Strong wind gusts to 50 mph are also possible in and near any showers. These winds could lead to brief periods of low visibility in blowing dust from any recently tilled fields.
