DISCUSSION (This evening through Friday)

Issued at 215 PM EDT Fri Oct 2 2026

Rest of This Afternoon through Saturday...

Forcing continues to shift south this afternoon, keeping the bulk of the rain south of central Indiana. There could be some sprinkles/light drizzle in the south as some light returns have been seen on radar. Will keep some low PoPs south, diminishing from the north as the afternoon progresses.

Clouds will take longer to diminish though. Lower clouds will diminish first, then mid and high clouds will eventually exit as well. Skies likely won't be mostly clear all areas until during the overnight.

High pressure will rule Saturday into Saturday night, providing quiet conditions. Some high clouds will move in from the south later Saturday into Saturday evening. Otherwise, skies will be mostly clear.

Lows tonight and Saturday night will be in the 40s to around 50. Highs Saturday will be in the mid 60s to lower 70s.

Sunday onward...

Northwest flow aloft will continue across central Indiana next week. At the surface, high pressure will be in control for most of the period.

A cold front will move through on Sunday, but the front won't have any moisture to work with as the Gulf is cut off. Another cold front will move in around Thursday night, but it too will have limited or no moisture to work with. Thus, will go with a dry forecast throughout the week.

Temperatures will rebound to above normal on Sunday ahead of the front, then return to below normal for Monday and Tuesday. Low temperatures may fall into the upper 30s across the northeastern forecast area Monday night. With light winds and mostly clear skies, will have to watch for the potential for patchy frost in favored cold areas.

As high pressure moves east of the area mid-week, southerly winds will bring back temperatures to above normal. There is some uncertainty on how much cooler air will be behind the late week cold front. Present indications that not much cooler air will move in before upper heights rise again and bring in warmer air beyond the 7 day period.

AVIATION (18Z TAF Issuance)

Issued at 100 PM EDT Fri Oct 2 2026

Discussion:

Showers look to remain south of the TAF sites. MVFR ceilings will gradually rise and break up from north to south through 00Z as drier air filters in. Some mid and high clouds will initially remain, but these will gradually diminish this evening.

A few gusts in the 15 to 20kt range are possible this afternoon.
