Many places across the eastern half of the state ended up with snowfall accumulations anywhere from a half an inch to as much as 3 inches across the northeast corner of the state. This system intensified as it moved into Wisconsin and produced snowfall totals up near 7″ of snow. Luckily we missed out on the majority of the snow, and now Tuesday we will be between this system and our next one, which will be moving out of Canada.
First of all it is to note, that some light snow may still be possible across the northeast corner of the state this evening. This will quickly clear out of the state by early Tuesday morning. Snowfall accumulations with this will be very light. No more than a half an inch will be possible.
On Tuesday, we will get a break in the weather before a clipper system moves out of Canada and dives right into Iowa Tuesday night. Highs on Tuesday will range from the 20’s across northeast Iowa, to near 40° across southwest Iowa. This clipper system will bring another chance of minor to moderate snowfall accumulations, mainly to the northwest and central portions of the state.
Snow will begin to enter northwest/western Iowa after 6pm Tuesday evening and will clear out of the western portions of the state by mid morning Wednesday. It will then enter into central Iowa after midnight, and will then exit the central portion of the state by early afternoon Wednesday. Eastern and southeast Iowa will see the snow start to fly around sunrise Wednesday morning and will have the snow around for much of the day Wednesday. After all said and done, the greatest accumulations will be across central and northwest Iowa. This is where 2″ to 3″ of accumulation will be with isolated higher amount possible.
Taking a closer look off of the 18z WRF run, it is also showing these similar snowfall totals that the 18z NAM run was showing in the graphic above. It is trying to show some isolated 5″ amounts near the Iowa/Minnesota boarder, however, I do not think we will see totals that high as this clipper system will be fast moving.
If you are traveling on Wednesday, you may run into some travel issues, however, you can always check 511ia.org for all of the very latest road conditions. The good news with this system is the winds will not be an issue, so reduced visibilities and blowing snow will not add to the travel nightmare. Thursday the weather will be great, with highs in the 20’s and decreasing cloud cover throughout the day.
