Rainfall continues south of the metro

Most of us saw a cloudy start to the day with mild temperatures.  Rainfall advanced into the state late this morning and throughout the afternoon hours south of I-70.  This is where our main chance of rain will remain this evening and overnight.  There was a sharp cut off from the rain today.  Locations north and east of Indianapolis remained dry and temperatures were a little bit higher as well.  This was due to lower dew points.  But locations to our south saw a thick deck of clouds all day, scattered showers and slightly cooler temperatures.

 Fox Futurecast has rainfall continuing Sunday morning south of I-70.  As you can see in the picture below, there is a sharp cut off once again for this rain shield.  At this point, the metro will be mainly dry but a few passing, isolated showers cannot be ruled out.  These showers would result in only a few one hundredths of precipitation and they wouldn’t last long.  The majority of the Sunday forecast will be dry from I-70 and to the north.  It’s south of this corridor that scattered showers remain possible again.

Rainfall potential on Sunday morning

The majority of the Sunday forecast here in Indianapolis will be dry with on the isolated chance for a passing shower. Temperatures will also be similar to the Saturday forecast with highs reaching the mid to upper 60s. Normally, temperatures should hit 70°F this time of year, so it’s not a huge departure.

Here’s a look at how much rainfall should accumulate through Monday evening.  As you can see, there is a sharp cut off like discussed above.  But that northern edge could shift a little, so dont’ rule out rain in the metro completely.

Rainfall accumulation through Monday evening

Monday through Wednesday will be dry for the most part with temperatures warming back into the low 70s.  But each of these days will hold an isolated chance for afternoon showers and storms.  There isn’t a guarantee on any one of these days that it will rain, just a 20-30% chance.  Better chances for showers and thunderstorms return Thursday afternoon and continue through Saturday.  This will once again bring back cloud cover and slightly cooler temperatures.
