FRIDAY - Showers during the morning. Another powerful front will plunge temperatures Tuesday and bring a better chance for rain. We will also be a little cooler Friday with an afternoon high of 60, only 2 degrees higher than the morning low.
A cold front moving through the area Thursday evening will trigger a broken line of showers and isolated thunderstorms. Dry time works in through the morning and into a good portion of the afternoon. High near 58. Northwest wind 6 to 14 miles per hour.
Overnight the temperatures will continue to drop. Most of the rain should move out through Saturday night.
Saturday: Colder with sunshine, then late day clouds.
As mentioned, the front may produce a few showers, especially during the late afternoon into the early evening with rain chances near 20% increasing briefly to 40% early Friday evening. High temperatures will be in the lower 60s.
Sunday night, the next storm system approaches the area, and will bring a chance for rain to eastern Iowa after midnight.
It will be partly sunny and in the upper-30s on Sunday.
Harsh winds will back off tonight; remaining southerly, but down to 5-10 miles per hour.
Sunday: Partly cloudy. Windy. Winds: SW 15-25 miles per hour. To express the low-uncertainty of the timing of this cold front, I'm giving a chance of scattered showers for Wednesday as of now. By the afternoon we will be looking at cloudy skies and breezy winds from the north, pulling the cooler air into the region.
Lows will be in the middle 50s Monday night. Skies will be mostly sunny, with highs around 40 degrees.
