MISSISSIPPI RIVER STAGE AT DUBUQUE: 17.3-FEET & FALLING
After a couple of days of dry weather, a series of weather systems will come back across the Midwest. These will each bring rounds of rain and thunderstorms to Iowa. Thunderstorms later on Friday, mainly after about 5 p.m., could be strong to severe. It appears the main severe weather risks will be from hail and strong wind. There is also a low tornado risk, although that will be in a fairly narrow place close to wherever the warm front ends up - that will be something we follow. Heavy rain will be possible from any of the periods of storms coming up. Adding up all the rain from Thursday night through Tuesday, widespread totals of one to three inches look likely. Higher amounts will happen where storms move over repeatedly. Rises on creeks and streams, and eventually some rivers, can be expected. The area most at risk of issues from rain will be generally south of Highway 30, where the heaviest rain has fallen recently and the ground is most waterlogged.

Isolated thunderstorms may clip southeastern Iowa Wednesday night and could be strong to severe. Nearly all of Iowa, however, will be storm-free from that system. Rain and thunderstorms will be more widespread Thursday night into Friday, followed by additional rounds of showers and thunderstorms Saturday through Tuesday. Heavy rain will be possible from any of these. Adding up all the rain through Tuesday, one to three inches will be very possible with locally higher amounts. Typically, an inch of rain over the course of a few days in May would be no problem, but the ground is saturated and so runoff will happen with just about any rain. Rises on creeks and streams, and eventually some rivers, can be expected. Where the heaviest rain falls will determine where the flooding potential is highest, and those details are uncertain at this time. You can follow the latest river levels at this page.
We’re getting a welcome break from rain, although it’s going to be short-lived. While much of the state has been wetter than average so far this month, some places are running a little behind. The rounds of rain coming up mainly Friday through Tuesday may put a dent in those deficits, and for the wetter places, it’ll just keep padding the statistics. Through May 21, Cedar Rapids has had 4.35 inches of rain. That’s 1.58 inches above normal. Iowa City has gotten 5.09 inches, which is 2.15 inches above normal. Waterloo is up to 4.05 inches, 1.04 inches above normal. On the flip side, Dubuque is one of the places that’s been a little behind on rain. 2.19 inches has fallen there, which is 0.62 inch below normal through May 21. In the map above, areas of green show where rainfall has been above normal. Yellow spots are where rainfall has been up to an inch below normal.
When the wind blows from the east, temperatures are rarely warm. That’s been true so far this month! 14 of 21 May days have featured wind with either an east or north component. Only one of those days made it to 70! The rest of them have struggled. Generally, the stronger the wind is blowing, the warmer (or cooler) you may be depending on which direction it’s coming from. Cedar Rapids’ average temperature for the month so far is around five degrees below normal, with rainfall that’ll likely surpass the normal as well. Cool and wet conditions tend to go hand in hand.
May is two-thirds over, and we haven’t had very many mild days to show for it. So far this month, only four days have had a high temperature of 70 or warmer in Cedar Rapids. That’s the lowest total through this point of the month since 1996! On average, a full half of our days would be at least 70 degrees. In addition, the average temperature of just under 54 degrees makes this the 10th-coolest May through today’s date. The weather pattern we’ve been in has also been a wet one (which doesn’t help out the temperatures). So far this month, Cedar Rapids has gotten 3.77 inches of rain. That’s the 16th-wettest May-to-date on record.
