Issued at 1231 AM CDT Thu Sep 18 2025

Low confidence TAF due to persistent scattered shower/storm
potential through the 18.06Z period. Radar imagery at 18.06Z TAF
issuance shows an arc of showers quickly progressing north
through southeast Minnesota and western Wisconsin into west-
central Wisconsin. KLSE ASOS registered a Trace with these
passing showers from 0515-0540Z.

The persistent weather pattern causes transient IFR visibility
potential from scattered storms primarily during the daytime
hours today. Higher, widespread storm chances progress east
across the forecast area tonight, as early as the 18-24 forecast
hour. Initial local higher storm chances primarily affect
smaller airports in southeast Minnesota (KAUM, KTOB) and
northeast Iowa (KCCY). Initial timing and eastern extent limits
overall confidence, below mentionable for KRST TAF, and will
need to be further investigated in coming TAFs (12-18hour
forecast).

FRIDAY THROUGH MONDAY.. Widespread, high storm chances Friday
and Friday night (60-80%). Low to moderate storm chances
(20-50%) Saturday through Monday.
