KEY MESSAGES

- Showers through midday with widespread low clouds beginning to clear late

- Dry and much cooler weather expected over the weekend into next week; potential for first lows to drop into the 30s across portions of central Indiana Tuesday morning

DISCUSSION (Today through Thursday)

Issued at 301 AM EDT Fri Oct 2 2026

Showers will pass through the area this morning as a cold front drops through the region, though disjointed and weakening upper level forcing has led to lighter amounts than previously expected.

Precip will gradually come to an end from northwest to southeast during the day today, though trapped moisture below a low level inversion will keep the area cloudy much of the day. This along with the low level cold advection behind the boundary will keep temperatures from rising more than a few degrees today at most. Skies will clear out tonight, allowing lows to drop into the 40s across the majority of the area.

The remainder of the forecast period will be dominated by two areas of surface high pressure, keeping temperatures near to below normal much of the weekend into early next week, and possibly providing an opportunity for the first patchy frost of the season next Monday night, particularly if winds can go light to calm and allow lows to drop even further than the current upper 30s across the northeastern portion of the area.

Some recovery of temps mid to late week is expected with modestly rising heights aloft and southwesterly low level flow reestablishing itself on the backside of the second surface high, and temperatures may creep back slightly above normal late week into next weekend for a very pleasant stretch.

A slow moving frontal boundary continues to push through the area, with showers along and behind it, as well as widespread restricted conditions, primarily ceilings.
