- Warming trend begins today and above normal temperatures will continue into next week.

DISCUSSION (Today through Tuesday)

Issued at 314 AM EDT Wed Apr 8 2026

The cold temperatures this morning will quickly turn to above normal temperatures the remainder of the forecast period. There will also be a few chances for rain and thunderstorms, first comes the end of the week then additional chances arrive next week.

At the surface, a large high pressure system is continuing to push eastward while a cold front approaches from the NNW. This will shift winds over central Indiana to out of the south by later today and WAA will take over, leading to highs in the mid 60s to near 70 today despite the cold start. Dry weather is expected today with minRH values near 30% likely this afternoon which will lead to slightly elevated fire conditions.

A LLJ will also be near the approaching cold front, and mixing later today will likely bring wind gusts near 25 mph from this afternoon on, mainly in our NW. Models are showing that the front, which is extending off of a low tracking north of the Great Lakes, will stall just to our NW by tonight and remain there through at least tomorrow night. This will keep the area under plenty of WAA as well as moisture advection allowing temps to get solidly into the 70s on Thursday with dew points increasing into the low 50s. During this time some rain will be possible in the far NW, but chances won't increase across the area until the front finally pushes SE through the day Friday. At this time rain amounts look to stay below half an inch but can't rule out higher amounts in localized areas. Until the front finally passes, wind gusts will continue to be a concern across central Indiana, with gusts up to 30 mph possible Thursday and up to 25 mph Friday.

Behind the front, another surface high will bring dry weather for the weekend as well as a quick drop in temps through Saturday but still near to above normal for this time of year.

Models show an active pattern possible for next week with SW flow setting up over the area. Temps will probably be a good bit above normal with highs in the 70s to near 80 in the forecast. While timing and details are unclear at this time, the next round of rain and thunderstorms is progged for at least the first half of next week.
