We had an early morning wake up call with thunderstorms this morning, then it was off to the races with temperatures for the rest of today. Our high temperature of 83 degrees today ties for the warmest high temperature so far for 2019 and it looks like it may be all down hill in the temperature department for Friday and beyond! Along with cooler temperatures, we’ll also contend with several rounds of showers and thunderstorms from tonight and lasting through this weekend.
The focus for thunderstorms for tonight will be across central and perhaps northern Iowa where a cold front is expected to stall out. Showers and thunderstorms are expected to develop first across central Iowa this evening before slowly building north towards northern Iowa after midnight and perhaps across southern Minnesota near daybreak Friday. The good news is that the threat for severe weather may remain just to our south, but we will need to watch out for the threat for heavy rainfall and perhaps some hail across northern Iowa for tonight.
The chance for showers and thunderstorms sticks around into Friday and while I don’t think it will be a washout of a day, it will be cloudy and cool. A more organized line of thunderstorms is expected to swing across southeast Minnesota and northern Iowa sometime late Friday afternoon and into the evening hours. I can’t rule out the threat for hail and damaging winds from this round of storms, but we will need to keep an eye out for heavy rainfall. High temperatures on Friday only top the upper 50s to lower 60s along with blustery, east winds.
The threat for rain and thunderstorms continues into this weekend as temperatures remains well below average for this time of the year. We may manage a dry start to Saturday with an increasing threat for rain and thunderstorms for Saturday afternoon and evening. Once again, the threat for severe weather may remain just to our south across central Iowa for Saturday, but we will need to watch out for hail with some of the stronger storms. High temperatures on Saturday may have a wide range across the area thanks to a warm front trying to move north with highs ranging from the 60s across southeast Minnesota to the 70s across northern Iowa.
Rain stick around across the region for Sunday with perhaps a better shot for rain throughout the daylight hours as high temperatures on Sunday only top the 50s. We finally catch a break from the rain on Monday as a ridge of high pressure moves across the Upper Midwest with high temperatures around 60 degrees.
