Short Term
Issued at 214 AM CDT Sat Oct 24 2026
Scattered clouds cover the area early this morning with light wind from the south-southeast. A surface low sits across North Dakota and Manitoba with trailing trough axis across the plains and attached to the developing southern stream cutoff low. As northern and southern streams separate today the approaching cold front stalls out. This keeps Iowa dry and warm today with precipitation across South Dakota and Nebraska. Winds may occasionally gust near 20 mph, but will be lighter than what occurred on Friday. By later this evening the surface boundary begins to sag into northern Iowa with spotty light showers possible. These continue off and on Sunday as the cloud front stalls out across northern Iowa. This will result in a rather notable temperature gradient across the area with far northern Iowa in the mid 50s while most of the state reaches the 70s.
Long Term
Issued at 238 PM CDT Fri Oct 23 2026
On Monday the southern stream closed low will transition into a negatively tilted more open wave and slip north into the midwest. Some CAPE is tucked right in the triple point, but the speed of the system keeps the warm sector out of the state until the overnight hours. CAPE will build on the warm sector of the front as it stalls across the middle of the state. Much of next week will have split weather between the north and southern half. The northern half will have more seasonal temperatures in the low 60s whereas 70 degree highs will be common across the south. Rain and some thunderstorms will remain in the picture. This pattern will remain until the east CONUS ridge is broken down by a stronger system from the west.
Aviation
Issued at 1029 PM CDT Fri Oct 23 2026
VFR conditions are expected to prevail through the TAF period. Main impact through the overnight will be LLWS particularly at KFOD/KMCW. Though surface winds near 10 knots will be present, latest analysis is showing 35-40 knot winds at 2kft with ~30 degrees of veering. The LLWS is expected to mix out shortly after sunrise. There is a low (~20%) chance of showers at KFOD/KMCW between 00-06z, and will need to be monitored for PROB30/TEMPO inclusion in future issuances.
