KEY MESSAGES

- Low impact forecast through the week with gradual warming ushering in mid 50 daytime high temperatures by late week. Low precipitation chances until Friday night/Saturday.

DISCUSSION

Issued at 1226 AM CST Sun Nov 15 2026

Gradually Warming Through Start of the Week:

Unification of an amplified, weakening area of anticyclonic flow and heights with the parent flow over the central CONUS through the rest of the weekend causes a split in moisture and mid level forcing, limiting local precipitation chances to north and south of the forecast area. Applicable local weather impacts will be persistent temperatures below freezing tonight before a gradual warm up ramps up through the start of the week. High temperatures today are forecast to be in the upper 40s to lower 50s with most areas reaching the upper 50s by Wednesday.

Precipitation Chances Increase Late week:

Long term global ensembles suggest return flow and accompanying moisture eventually advecting into the Upper Mississippi River Valley through midweek with 100% probabilities for 0.5" PWATs. Accompanying long term member sounding profiles struggle to suggest overall saturation, potentially resulting in only increasing cloud cover Wednesday night into Thursday. Subsequent precipitation chances progress from west to east Friday night through Saturday associated with an accompanying cold frontal boundary. Temperatures return back down to the 40s late next weekend as a result.

Before the cool down this upcoming weekend, the warmest temperatures are expected mid to late week with high temperatures in the mid 50s to even potentially to low 60s.
