TONIGHT

Tonight will remain calm and seasonably chilly as high pressure slowly shifts eastward, allowing southerly flow to develop across central Indiana. Expect partly cloudy skies and lows dipping to the upper 20s. Winds from the south southeast at 5 to 10 mph will help maintain the steady warmth overnight.
