- Next chance for widespread rain will be late Saturday into Sunday

FORECAST UPDATE

Issued at 908 PM EDT Wed Jun 3 2026

Beautiful weather continues this evening as the region resides under high pressure. 01Z temperatures were in the 70s with light winds.

The forecast is in excellent shape for the overnight as conditions remain tranquil. Cirrus drifting across the area currently will diminish over the next few hours leaving another night with clear skies. Temperatures will fall into the mid and upper 50s by daybreak.

Zone and grid updates out.

DISCUSSION (This evening through Wednesday)

Issued at 250 PM EDT Wed Jun 3 2026

Surface high pressure over the Midwest is expected to persist through Friday. As such, mainly clear and dry weather is expected to round out the week. The surface high begins to slide eastward on Thursday, however, allowing winds to become southwesterly. Wind direction has been predominately out of the northeast over the past few days. This change of wind direction will allow for a warming trend with highs climbing into the mid 80s both Thursday and Friday.

As the high reaches the Mid-Atlantic coast, troughing over the Great Plains will edge eastward into the Midwest. A low passing to our north will drag a cold front southward through Indiana on Saturday. This front, combined with gradual moisture advection northward, will set the stage for scattered showers and thunderstorms both Saturday and Sunday.

Severe weather is not anticipated at this time. Overall, upper-level flow looks to be weak and sufficient shear for storm-scale organization is not likely to materialize. Isolated downbursts can not be ruled out, however, as is usually the case with single-cell / pulse convection. Flooding may be a possibility if the cold front slows in its progression southward. Slow-moving storms and or repeated storms over a few days may allow for this possibility.

Ensemble guidance hints at the cold front lifting back northward as a warm front early next week. This may keep showers and storms in the area Monday through Wednesday. Additionally, the warming trend resumes with high temps slowly climbing into the mid/upper 80s next week. Low-level moisture looks to increase as well next week, with dew points into the 60s becoming a common occurrence. As such, the probability of heat indices near or over 90 degrees is increasing.

AVIATION (06Z TAF Issuance)

Impacts:

- None

Discussion:

VFR conditions will continue through the forecast period.

Surface high pressure over the eastern part of the country will keep winds light and variable overnight. As surface high pressure slides further eastward today...winds will veer to south then southwest at 10 to 15kts into the afternoon before backing to light southerly this evening.

Cirrus overnight will gradually diminish in coverage after daybreak. May see a few diurnal cu sneak into the southern half of central Indiana Thursday afternoon as a subtle increase in low level moisture lifts into the region. Increasing cirrus will overspread the region from the west this evening.

IND WATCHES/WARNINGS/ADVISORIES

None.
