KEY MESSAGES

- Cooler temperatures are expected through the weekend, with lows around freezing through Sunday night

- Highs return to the 60s early next week, but cooler temperatures will return mid-late next week

- Isolated to scattered showers are possible Wednesday night into Thursday

DISCUSSION (Today through Friday)

Issued at 251 AM EST Sat Nov 7 2026

Today through tonight...

Latest satellite observations depict low clouds have mostly cleared out across central Indiana as northwest flow continues to filter in drier air. Mostly clear skies along with winds becoming light from a weakening pressure gradient has allowed for temperatures to quickly drop well into the 30s already. Expect temperatures to continue cooling with lows in the upper 20s to mid 30s. Patchy fog development also appears increasingly likely in climatologically favored locations as winds have been very light or calm at times. Any fog that develops should quickly mix out after daybreak. Scattered to broken lake enhanced low clouds still remain across far northeastern counties and will likely persist through at least the first half of the day. These clouds may limit diurnal temperature swings to some degree.

Surface high pressure centered near northern Missouri early this morning will shift eastward through the day today promoting quiet weather conditions. Mostly clear skies and light winds tonight may once again support patchy fog development in climatologically favored locations, but winds will increase slightly late overnight leading to some uncertainty. Look for highs in the low to mid 50s today with lows dropping into the upper 20s to low 30s tonight.

Sunday through late next next week...

Quiet weather conditions are expected to continue through the middle of next week as surface high pressure generally remains in control. Ensemble guidance depicts a few subtle systems pushing weak cold fronts into the region, but gulf moisture remaining cutoff will keep these fronts moisture starved, allowing for dry conditions to persist. A cold front will move through on Sunday bringing breezy conditions with southwesterly wind gusts between 20 to 30 mph possible. Winds should then quickly taper off into Sunday night once the pressure gradient relaxes as the cold front departs. Light winds combined with mostly clear skies could support additional fog development Sunday night into Monday morning.

A few shortwaves are expected to move through the region next week after the cold front on Sunday passes. These upper waves will likely push through a few more fronts through the area during the week. The only system that could potentially support precipitation is a shortwave moving in from the northwest late Wednesday into Thursday. Weak to modest forcing and very limited moisture return supports a low (20-30%) chance for rain.

Return flow will warm highs into the 60s early next week. Strong cold air advection associated with deep troughing and a cold front is then likely going to cool temperatures significantly mid-late next week. Highs are only expected to reach the low to mid 50s by Thursday and highs will struggle to get out of the 40s on Friday.

AVIATION (12Z TAF Issuance)

Issued at 633 AM EST Sat Nov 7 2026

Impacts:

- Patchy fog at LAF diminishing by 13Z today, additional patchy fog possible late tonight into Sunday morning at LAF

Discussion:

Predominately VFR conditions are expected through the period. Patchy fog is ongoing at LAF and is expected to mix out by 13Z. Additional patchy fog may develop late tonight into Sunday morning, mainly near LAF.

Look for NW winds during much of the day. Winds will back to more westerly and then southwesterly this evening into tonight as surface high pressure slowly moves east. Winds will pick up some during peak afternoon heating (17-21Z), but should remain at or below 10 kts.

IND WATCHES/WARNINGS/ADVISORIES
