Sunday rainfall and major warm up on the way

Spotty showers moved into Central Indiana on Saturday evening as a weak low pressure system slid just south of the state.  Showers and isolated storms will continue overnight and easily into Sunday morning.  But this doesn’t mean it will rain the entire night.  There will be on and off showers with varying intensity.

The chance for scattered showers and isolated storms will continue on Sunday as this system and an upper level wave pass through the state.  Again, this isn’t a guarantee for rainfall but on and off chances during the day.  Temperatures also remain cool on Sunday with highs ranging from 61-63°F.

By the time this system is done, we should see around .5″ of rainfall in the metro.  This rainfall will range from amounts lower than .2″ our northern counties to nearly 1″ in our southern counties.  The higher amounts of rainfall will come in closer to the low pressure track to our south.

Now let’s dive into the work week!  Temperatures will climb quickly for the first half of the week.  Skies will be partly cloudy Monday through Wednesday.  Highs on Monday will reach 70°F and we’ll be up to 80°F by Wednesday.

The problem later this week will be an upper level low developing out to our west.  This type of system typically brings several days of cloudy skies, rainfall and much cooler air.  It pulls much cooler air to the surface and it should cool us back down to 55°F by Friday.
