It was a cold start this morning with some readings in the single digits. The map below shows the morning low temperatures.
Tonight will not be as cold with lows expected to be in the upper teens.
There are some high thin clouds across Iowa this afternoon (see map below). Those clouds will move east this evening leaving behind a mostly clear sky.
Wednesday and Thursday will be a warm each day with plenty of sunshine. Mid 40s are possible on Thursday. Friday is a little tricky at this point. It will all depend on the exact position the forecast is across the area. Right now there are some indications the front will be south of Iowa. Here is the HPC forecast position of the front Friday morning.
If it is, we will have a day with lots of clouds and highs in the upper 30s and maybe some drizzle. If the front is north of Iowa, we will have sunshine and highs in the mid-upper 40s. At this point, I am leaning toward the clouds and cooler temperatures. I have not put drizzle in the forecast but I do want to mention it in the discussion. Also if we do have drizzle we have to watch when it happens in relation to the temperatures. Again, the details are yet to be known at this point.
Saturday and Sunday will be warmer with highs in the low 50s. There is a slight chance of an afternoon shower on Saturday. The weekend looks nice if you like warmer weather during this time of year.
We are tracking a cold front that is forecast to track across the state on Monday. Ahead of the cold front and south of the warm front, the wind will be strong pushing highs into the upper 50s. The cold front might bring a few showers during the afternoon/evening as it crosses eastern Iowa. Here is the forecast postion of the cold front west of Iowa Monday morning.
The cold front will be east of Iowa Tuesday with high temperatures a little cooler. The wind will still be gusty but this time from the west.
