It was another dreary day with temperatures will below normal with light rain/drizzle. Light rain/drizzle will mix and/or chance to a few snow showers tonight as temperatures drop to near 30 degrees. The roads that are wet as temperatures drop below freezing could be a bit slick late tonight.
The 500 mb low (see map below) will be tracking east over Iowa tonight and Friday. It will cool the atmosphere down below freezing for a chance of a few snow showers tonight and Friday morning.
Yesterday I mentioned we might have some minor snow accumulation (1” or less). It doesn’t look like any accumulation will happen. The ground is warm and any snow that does fall probably won’t fall fast enough to accumulate. The best chances of getting 1”+ of snow will be north of Iowa (see map below).
Saturday will be a little warmer with a few rays of sunshine, but more clouds are expected than sun. Sunday will be warmer and windy as we track the next area of low pressure. It is forecast to track from Wyoming Saturday evening through the Midwest Sunday and bring us a good chance of showers and storms. Here is the forecast position of the low Saturday evening.
At this point the Storm Prediction Center does not have any risk for severe storms for eastern Iowa Sunday.
Once that storm moves east the weather will remain dreary. Monday and Tuesday will be mostly cloudy with a few light rain showers. Another low pressure system is forecast to bring rain to the area Wednesday and Thursday. On computer model show a possibility of colder air Thursday and maybe some snow chances Thursday night. I am going to just put rain in the forecast at this point because it is going to be hard to get snow to accumulate as we get towards the end of April. The storm does have a lot of wind with it. We will continue to track it and have more information as it gets closer in time.
