Forecast update

Issued at 952 PM EDT Fri Oct 30 2026

The forecast remains in good shape with only minor adjustments made in the latest update. Latest satellite imagery depicts extensive mid- high clouds pushing into central Indiana from the west as a system over the Plains continues to approach. Residual dry air in the lower levels should mostly limit precipitation chances through the overnight, but a few light showers cannot be completely ruled out across northwestern counties, where there is slightly greater moisture and marginal forcing. Increasing clouds will keep temperatures slightly warmer compared to last night, generally in the upper 40s to mid 50s.

.DISCUSSION (This evening through Friday): Issued at 253 PM EDT Fri Oct 30 2026

This afternoon:

Skies remain mainly clear after last night's cold front with temperatures suppressed by about 10 degrees. Highs so far have been in the low to mid 60s with expected temps near 70 later this afternoon. Overall, winds out of the northeast should keep weak cold air advection in place through the day today. Additionally, dry air advection continues with dew points a few degrees lower than guidance due to efficient boundary layer mixing.

Clouds increase and thicken overnight keeping temperatures warmer than previous nights. Most locations should expect to see lows in the 50s but portions of our northeast may dip into the 40s. A few showers may even creep into our northwestern counties late in the night. Overall, precipitation chances should remain low and amounts light if any.

The culprit is a weak trough ejecting into the Plains this afternoon. This feature is interacting with a tropical moisture plume associated with the remnants of Hurricane Vance. Guidance shows the trough weakening as it lifts northeastward towards Indiana. Trends within guidance have been towards a drier solution over the past few days. Our best chances of rainfall are late Saturday into Sunday with the primary trough axis swinging through.

Monday through Friday:

An active pattern with repeated rounds of precipitation is likely through next week. The upper level trough associated with the expected rainfall this weekend will be exiting the region early Monday morning. A few lingering showers are possible Monday with PWATs around 1.3 inches and dew points in the mid-to-upper 50s across Indiana in the wake of the trough.

At the same time, models suggest a secondary upper level trough will start to evolve over the Great Plains. An associated strong surface low within the broader cyclonic flow regime will advect unseasonably moist air into the region from the Gulf, with PWATs around 1.5 inches and dew points potentially in the lower 60s. Coupled with 50- 55 kt SW flow at 500mb and strong isentropic ascent, sufficient moisture and lift exists for rain and a thunderstorm or two across the region starting on Tuesday and lasting through Wednesday.

However, there is model uncertainty of the evolution of the trough as Thursday approaches. While the GEFS and EPS ensembles show the surface low exiting Indiana into Thursday morning, bringing cooler and drier air behind it, the GFS indicates the potential of a split flow regime may develop. In tangent to the split flow regime, a secondary surface low may form in portions of the mid MS valley bringing another wave of broad cyclonic flow across indiana. The new surface low could bring another wave of unseasonably moist air and more isentropic ascent. If this scenario were to happen, expect additional rainfall and isolated thunderstorms for Thursday. Rainfall totals through Thursday will range from 0.75-1.75 in depending on the evolution and speed of the upper level through.

By Friday, any precipitation will move out of Indiana bringing quiet and calm conditions. Temperatures Friday should remain in the mid to upper 60s.

.AVIATION (06Z TAF Issuance): Issued at 114 AM EDT Sat Oct 31 2026

Impacts:

- None

Discussion:

Widespread mid and high cloud will gradually continue to overspread the area with ceilings slowly dropping to near 8-12KFT through the period as a modest upper level disturbance moves toward the area.

A sprinkle or shower cannot be ruled out at times during the period, but low level dry air is likely to severely limit this potential, with virga the most likely outcome. Any precip would be light and unlikely to cause impacts.

Winds will generally be easterly through the period, between 080-110 degrees, strengthening to 8-10KT during the daytime and dropping to 4-8KT or less overnight.

Watches, warnings and advisories

None.
