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

- Highs return to the 60s early next week

FORECAST UPDATE

Issued at 958 AM EST Fri Nov 6 2026

Drizzle/mist has been reported across portions of the area this morning, mainly near and south of I-70. The drizzle should gradually shift south as weak forcing moves south. Updated the forecast to include drizzle as needed this morning. Lake enhanced showers may still get into the far north and northeast area, so kept the low PoPs there.

Sky cover will be a bit more complicated with drier air clearing the skies from the north in the far northwest forecast area. This trend should continue for a while in the far west, but additional clouds are trying to move south from Lake Michigan. Some cumulus may also pop where skies clear initially with colder air moving in aloft.

For now though, will still allow skies to become partly cloudy west into early afternoon with drier air eventually winning out. Some breaks in the clouds may appear elsewhere as well, but clouds from the lake will still move south, potentially creating a variable cloudiness environment.

Lowered hourly temperatures this morning based on current trends but left highs alone for now given uncertainties in sky cover.

DISCUSSION (Today through Thursday)

Issued at 258 AM EST Fri Nov 6 2026

Today through tonight...

Latest surface and satellite observations depict extensive clouds across the region as a system moves through region. An associated cold front currently centered near northern portions of central Indiana is quickly pushing southward. Low-level convergence along the boundary has promoted scattered light showers. Patchy drizzle has also been reported at times ahead of the cold front. Look for scattered light showers or drizzle to remain possible through about daybreak drier air begins to filter in.

At least partial clearing is expected during the day due to cold air advection behind the front. However, mostly cloudy skies should persist for much of the day aided by lake enhanced low-level moisture. Isolated lake enhanced showers or patchy drizzle cannot be ruled out either, mainly across far northern counties. Limited diurnal heating from mostly cloudy skies on top of continued cold air advection will keep highs in the low-mid 50s. Clearing skies late in the day into the evening along with winds becoming light overnight supports efficient radiational cooling. Look for lows to drop into the upper 20s to mid 30s tonight.

Saturday through the middle of next week...

Quiet weather conditions are expected this weekend 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 through the region during this period. Gulf moisture remaining cutoff will keep these fronts moisture starved though allowing for dry conditions to persist.

Look for highs to remain in the low to mid 50s Saturday before return flow helps temperatures moderate into early next week. Highs on Sunday will generally range from the upper 50s to low 60s with widespread highs in the 60s to start the work week. A cold front moving through midweek should cool highs back down into the 50s by Thursday. Widespread lows in the upper 20s to low 30s are expected Saturday night into Sunday.

AVIATION (12Z TAF Issuance)

Issued at 646 AM EST Fri Nov 6 2026

Impacts:

- MVFR ceilings expected to improve to VFR late this morning into the afternoon, brief IFR vis/ceiling possible at KBMG through 13Z.

Discussion:

A cold front is now pushing southward through southern portions of central Indiana. Widespread MVFR ceilings are ongoing with brief IFR ceilings at BMG as the cold front is currently moving through. Look for these ceilings to improve to VFR late this morning and into the afternoon with drier air filtering in.

Drizzle will be possible over the next few hours mainly near BMG. A stray light shower cannot be ruled out either at IND today. Confidence is far too low for a TAF inclusion. Look for winds to remain out of 320-360 degrees during the period with sustained speeds of 07-12 kt today. Sporadic gusts between 15-19 kt appear possible at times. Winds then become light this evening into tonight.
