Tonight: Our threat for severe weather has winded down with a few lingering showers north of highway 20. For everyone else, it should be a pleasant evening with partly cloudy skies. Through tonight, our skies will become mostly clear to partly cloudy. Some fog may develop, especially north. Lows will be in the mid to upper 50s and near 60 south. Winds will be light and variable.
Sunday: The entire day hinges upon a possible line of storms developing in northwest Iowa early in the morning. This will barrel toward eastern Iowa through the morning but the question is will it roll through in the north or further south? This will bring a chance for severe weather with damaging wind gusts as the main threat. Some hail and heavy rain is possible. The best chance for severe weather will be west.
That should clear by the late morning or early afternoon with a period of partly cloudy skies to follow. Meanwhile, a south wind will transport warmth and moisture with highs in the mid to upper 80s (if we can get enough sunshine) and pretty humid air. This will allow for more storms to develop later in the evening, some of which could be strong to severe with large hail and damaging winds. Scattered showers and storms will continue Sunday night with lows in the low and mid 60s.
Memorial Day: We should stay warm for Memorial Day with a south wind but I think we will see partly sunny to mostly cloudy skies with a likely chance for rain and storms. Highs will be in the low to mid 80s with continued humidity.
Next Week: A stationary boundary will bring rain chances almost everyday, dwindling as we make our way to Thursday. We will see more clouds than sun up until Thursday when skies will turn partly cloudy for the rest of the week and weekend. Highs will stay above average in the upper 70s and low 80s.
