After one storm leaves, it’s now time to look ahead to the next one. Our next system will start to move in early tomorrow morning and will exit by Saturday morning. The difference with this storm system is it will impact southern Iowa. So the folks in southwestern Iowa, you finally have a shot at getting some snow! The greatest snowfall totals will occur south of intestate 80, but snow will fall as far north as highway 30.
Friday morning, snow will begin to fall across southern Iowa. This band of snow will stay mainly south of interstate 80. The timing of this snow will be after 4am tomorrow morning across southwest Iowa and will begin to fall in south central Iowa after 7am. Snow will have issues reaching northern Iowa tomorrow morning due to the surface high remaining in place across the north. This is why we will see a very sharp gradient between accumulating snowfall and little to no snowfall.
The second round, which has more moisture will then move through Friday night into the morning hours on Saturday. This is when we will see the best shot of light snow reaching highway 30. After the snow pushes out by late Saturday morning, totals across southern Iowa will range from 2” to 5”, with a range of 1″ to 3″ from highway 30 to interstate 80. There is a slight potential that from highway 20 to highway 30, you could see a trace to as much as an inch, but this will be difficult to determine an accurate amount due to that surface high causing a sharp total gradient. Now if the surface high moves out of the area, or we see a more northward track of the storm system, then totals will need to be adjusted. The good thing with this system is winds will be light, ranging from 5mph to 10mph, so this will help not cause additional travel headaches.
We will continue to watch this system very closely and will bring you the very latest updates on our Facebook page and right here at Iowachase.com.
