A weak 500mb wave and 850mb WAA and fgen will slide east and southeast over the region this afternoon into tonight. While thunder isn't expected, rain will occur over the area, with accumulation between a tenth to a quarter of an inch into tomorrow morning.

LONG TERM
Issued 317 PM CDT Tue Oct 14 2025
Thursday through Tuesday:
WAA related rain is expected to lift northeast of the area during the day on Thursday. Temperatures will rise for Friday, with highs in the upper 70s and breezy south winds. A cold front is then expected to move in Friday into Saturday, with varying solutions across the global models regarding timing. Euro and Canadian solutions favor a slower frontal progression that would have showers and thunderstorms lingering through Saturday afternoon, while the GFS pushes the front through quickly by Saturday morning, leading to a relatively dry Saturday. Given model discrepancies, it is a bit too early to definitively answer whether or not Saturday will be dry. Trends will be monitored heading toward the weekend.
