Forecast Update

Issued at 909 PM EDT Wed Oct 21 2026

Surface analysis late this evening shows strong high pressure stretching from the eastern Great Lakes across Indiana and Illinois to MO and Arkansas. GOES19 shows mostly clear skies across the state and winds were light to calm with dew points mainly in the 40s.

Aloft, strong ridging was in place across the Plains, extending north into Canada. This was providing NW flow aloft over Indiana and water vapor shows subsidence across the region.

Overall, another quiet and cool night will be in store as good radiational cooling conditions exist. Look for the clear skies to continue as lows fall into the 40s. HRRR fails to suggest much in the way of fog development. This still cannot be ruled out however due to expected low dew point depressions and calm winds. Ongoing forecast remains in good shape.
