Area Forecast Discussion National Weather Service Northern Indiana 600 PM EDT Mon Apr 20 2026
KEY MESSAGES
- A return to well above normal temperatures starts Tuesday.
- There is a 30% to 40% chance of showers, and perhaps a thunderstorms, Tuesday night. Better chances (70-90%) of showers and storms Friday.
DISCUSSION
Issued at 104 PM EDT Mon Apr 20 2026
After a cold start to the day, temps have rebounded somewhat into the 40s and eventually some 50s as the CAA wanes and shifts east. A rapid return of warmer air commences tonight and through the remainder of the week with the only hiccup being a weak disturbance and associated sfc cold front that pushes through Tuesday night with scattered showers (isolated storm?) as steeping lapse rates and a bit of an EML settle in with some upper level support. No severe weather is expected and overall rain amounts should not be significant.
Wednesday into most of Thursday night will feature dry and much warmer conditions as a closed low moves along the International border towards the area. A few showers or storms could arrive late Thursday night in the west, but better chances look to occur on Friday with likely to cat pops warranted ahead of this feature.
PWATs over 1" may signal some locally heavy rain concerns, but the system appears to be rather progressive so hopefully this doesn't become an issue.
Temperatures will then drop back to more seasonable levels for this weekend.
AVIATION /00Z TAFS THROUGH 00Z WEDNESDAY/
Issued at 600 PM EDT Mon Apr 20 2026

Winds will remain light tonight and then pick up out of the southwest in advance of a cold front during the day on Tuesday with gusts to near 25 knots at times. This cold front then arrives just beyond this period (Tuesday night) with chances for showers/storms and flight restrictions.
