KEY MESSAGES

- Dry and quiet weather continues through this weekend

FORECAST UPDATE

Issued at 1001 PM EDT Mon Oct 19 2026

Quiet weather will continue across central Indiana overnight with high pressure remaining in control. Some high clouds will move across at times, making skies partly cloudy for some of the time overnight.

For now with the clear skies and light winds, temperatures have dropped very quickly once again. Have lowered hourly forecasts to match the trends in observations. Have also nudged down low temperatures, mainly in areas that have cooled down the most. Wouldn't rule out some isolated frost, but coverage is not expected to be enough for any advisory.

DISCUSSION (This evening through Monday)

Issued at 317 PM EDT Mon Oct 19 2026

Pleasant, sunny fall weather will persist throughout the forecast period as upper level ridging and broad surface high pressure dominates the weather pattern.

Each day through at least the work week will largely be the same with mostly clear skies, light variable winds, and pretty consistent temperatures. Highs will range from the upper 60s to low 70s while overnight lows will be in the low to mid 40s. By the weekend, overnight lows could warm ever so slightly, into the upper 40s, as southern flow strengthens due to ridging to the west becoming more amplified. Going into the weekend will likely also see a slight increase in dew points as well as upper level moisture which could produce scattered clouds.

Given the dry weather, there is some fire weather concern through the next week. Winds will luckily stay low and RH values are expected to stay above critical threshold, but do take precautions with open fire.

Looking into the long range, the next shot of precipitation does not look possible until next week with the chance of a frontal system moving through.

AVIATION (06Z TAF Issuance)

Issued at 128 AM EDT Tue Oct 20 2026

Impacts: None expected

Discussion:

VFR conditions will continue through Tuesday evening near central Indiana terminals under axis of broad and amplified ridge of autumnal high pressure drifting slowly east over Indiana. A couple small H500 weaknesses embedded in overlying zonal ridge will provide FEW/SCT cirrus, especially near KHUF/KLAF, and mainly before 18Z.

Brief MVFR visibility is possible in patchy fog outside of KIND, yet confidence too low to include in any TAF. Winds will be often light and variable...with headings 040-090 degrees favored after 14Z, amid flow mainly 5KT or less.

IND WATCHES/WARNINGS/ADVISORIES

None.
