After a beautiful day Saturday, we'll see sunshine, heat and more humidity Sunday afternoon. Temperatures will be approximately 6° to 8° warmer than Saturday - highs will top out in the upper 80°s.
A warm front will pass through central Indiana during the early afternoon. Once the front passes, humidity will increase - from the southwest - and take heat indices in to the lower 90°s.
THUNDERSTORMS ARRIVE SUNDAY NIGHT
Computer models continue to advertise a cluster of thunderstorms moving south/southeast out of northern Illinois Sunday night. There is still some question as to when the line of storms will arrive in central Indiana.
The above high-resolution computer model brings thunderstorms in to the northern portion of the CBS4 viewing area starting around 10pm. The line will move south through the area reaching Indianapolis between midnight and 2am. Rain should exit the viewing area by 5am Monday.
I am not expecting widespread severe weather, however there could be an isolated severe thunderstorm. The main threat from thunderstorms will be gusty, damaging winds. There could also be small hail along the line.
KEEPING EYES ON POTENTIAL HEAT WAVE
Long range computer models continue to advertise the potential for a heat wave developing in the Midwest late this week and through the weekend. This could bring the season's warmest air to date. Stay tuned!
