Clouds will continue to increase this afternoon and this should keep temperatures steady for several hours. At 4 PM, temperatures remained below the 80 degree across our viewing area and this should remain the case as the day wears on. Here were the highs so far as of 4 PM (the actual temperature in Indianapolis at 4 PM had fallen back down to 76°F for Indianapolis).
Skies remain partly cloudy overnight and lows fall to the upper 50s. Much of Monday will be partly cloudy with a few more clouds building later in the afternoon and evening hours, especially north of I-70. Rainfall chances don’t look as promising now for Monday as the approaching system won’t be far enough to the east to influence us yet. Regardless, it’s not like the rain chance was even that great to begin with for Monday. What I’m seeing now is a 10% chance.
Isolated showers will be possible Tuesday afternoon as the warm front lifts through the state. This same front will also bring back high humidity levels and more oppressive feeling conditions. The refreshing air of Sunday and Monday will definitely depart. Better chances of rain start to develop Tuesday night and especially throughout Wednesday. This will be the start of a good soaking rain for the state. From what I’m seeing this afternoon, .70 to 1.01” of rain is the range for Tuesday-Friday with locally higher amounts possible. The new Canadian is still the outlier at 2”. As always, it needs to be watched and adjusted. But regarding the best chance of rain, that is definitely Wednesday with overcast skies and likely showers. The chance of rain continues on Thursday but it won’t be as widespread or soaking. Same goes from Friday as well.
Cool and drier air will finally arrive behind this system for the coming weekend and temperatures should easily be below normal August levels in the low 80s.
