Category: 7-Day Outlook
Highlights:
- Best weather of the week is today
- Strong to severe storm potential Sunday and Monday
- Widespread heavy rain threat mid week
- Unsettled pattern continues
We’re opening the weekend with dry skies across central IN, along with a very tropical feel. The combination of a nearby weak boundary and the humid air mass will help fuel isolated to widely scattered storms this afternoon. That said, overall coverage of storms will be reduced from what we saw Friday. Most of the day will feature dry conditions.
We’ll begin to increase storm chances as we rumble into the second half of the weekend and on into the new work week. Some of these may be strong to severe Sunday-Monday, including strong damaging winds and large hail.
Attention will then shift to mid week and the potential of an excessive rainfall event. Modeling is leaning towards tracking a tropical disturbance north out of the western GOM (Gulf of Mexico) before shifting northeast around the periphery of a southeastern ridge. Very heavy rainfall would result if this idea pans out. Stay tuned.
Upcoming 7-Day Rainfall Potential: 2″-4″ (locally heavier totals)

Highlights:
- Hot and humid weather
- Better storm chances return Friday PM
- North briefly drier Saturday
- “Rinse and repeat” pattern early to mid next week
Heat and humidity will remain the big weather story Thursday with only an isolated storm chance. Most should stay rain-free Thursday. Better rain and storm chances will rumble into the central IN picture Friday afternoon into the nighttime hours. We think a frontal boundary will slip just far enough south to provide drier times from I-70 and points north Saturday. Live across the southern half of the state? Prepare for more scattered to numerous showers and storms. Everyone will get back in on the periodically stormy times during the second half of the weekend into next week. It’ll be plenty humid as well.
Upcoming 7-Day Rainfall Potential: 1.5″ – 2.0″

Highlights:
- Big time heat and humidity through late week
- Watching storm chances Wednesday night
- Briefly drier air Saturday
- Summer-like pattern continues next week
The big weather story over the second half of the week will be the heat and humidity. Many will reach, or exceed, the 90 degree mark Wednesday and/ or Thursday. We’ll keep a close eye on the northern portions of the state for storms to initialize Wednesday afternoon/ evening. Those at greatest risk for strong to severe storm potential will be from areas along and north of the I-70 corridor Wednesday evening. Damaging winds and hail are of biggest concern.
A cold front will slide into the area Friday and provide better coverage of showers and thunderstorms Friday afternoon and night. Latest model runs then deliver a briefly drier surge of air Saturday and we’ll lean in that direction with our Saturday forecast for now. Don’t get used to the drier air as heat and humidity will be plentiful early next week, along with renewed shower and storm chances.
Upcoming 7-Day Rainfall Potential: 1″ – 1.5″

Highlights:
- Stormy tonight for some
- Heat builds this week
- Better storm chances return for the weekend
A cold front remains off to our northwest as we type this and big storms are firing across northern portions of the state. We’ll keep a close eye on those as they move southeast tonight and begin to pick up more forward momentum in the coming hours. They’ve had a history of producing damaging hail. Remain weather-aware this evening.
Thankfully we’ll begin to inject a drier air mass (briefly) into the region Tuesday. A nice day is coming with lower humidity. Most of the second half of the work week will also remain dry, but as humidity increases we have to mention the threat of an isolated to widely scattered storm. The big story will be the heat as highs push into the 90 degree territory. Prepare to sweat!
Better chances of showers and thunderstorms will push back into the region over the upcoming weekend. We’re not forecast a complete washout either Saturday or Sunday, but with a very humid air mass in place, any shower or storm that develops will have the capability of producing torrential downpours.

Highlights:
- More like summer
- Mostly dry weekend
- Keeping a close eye on Sunday night storm threat
- Unsettled to open the week
The story to wrap up the work week will be one much more typical of early June- warmer days are on deck with increasing humidity. The combination of the increasingly muggy air mass coupled with a weak upper level disturbance, could ignite a shower or storm Friday. Most of the day will be dry, however. The upcoming weekend will feature beautiful weather conditions- dry and warm to hot. We continue to watch a storm complex that could deliver a round of strong to severe cells (damaging straight line winds being the biggest concern) Sunday evening and night. We’ll have to tighten up potential timing as we progress closer to Sunday, but think most of the daytime hours will be dry. Early next week will likely open a bit unsettled.
Upcoming 7-Day Rainfall Potential: 0.50″ – 0.75″
