Severe Weather: There is a slight risk for severe storms this evening for the southeastern corner of Indiana.  Aside from flooding, the embedded t-storms could produce damaging wind and isolated tornadoes.  The SPC is still discussing whether or not to issue a watch.  Stay tuned.


Rainfall Totals:  As expected the southern half of the state has the highest rainfall totals.  We have tied a daily rainfall record at 1.49″ (old record set in 1918).  The NWS says: 2+ inches of daily rainfall in December in Indy has only occurred 4 times since 1871.  Saturday may be the 5th day.  These pictures below reflect the storm total for rainfall (about 48 hours).

Watch/Warning: Flash Flood warnings have been posted for many counties in southern Indiana through tonight.  A flood warning continues for much of central Indiana until 8pm.  Small streams, rivers and streets with blocked storm drains will flood.  River flood warnings are posted through next week.  Some locations could see major flooding.

Timing Rain to Snow: The heavy rain continues overnight through Sunday daybreak.  The heavy rain tapers off to occasional showers by Sunday afternoon.  Colder air sweeps in later in the day so we could see a rain/snow mix to then flurries and snow showers by Sunday evening.  Flurries stick around through the daybreak commute on Monday.

Temperatures: There is quite the temperatures gradient across the state now.  Lows tonight stay fairly steady compared to what we have now.  Highs on Sunday will peak early in the day.  Temps fall throughout the afternoon and evening until we hit lows in the teens and lower 20s Sunday night.


Extended: Colder temperatures and drier air will take over for the first half of the week.  Christmas Eve and Christmas Day look dry and cold.  Our next chance for snow moves in Thursday.
