INDIANAPOLIS, Ind. --Good Saturday evening! Temperatures this morning were in the upper 40s and low 50s. The low in Indy was 53 degrees and just three degrees shy of tying a record. Lows Sunday morning will be near 60 degrees with east winds 3 to 6 mph. Temperatures will only get into the upper 60s Sunday with a cloudy sky and rain.

Periods of heavy rain is forecast with rainfall amounts of 1.5 to 4 inches possible through Monday afternoon. Here is a look at one of the computer models which seems reasonable. Don't focus too much on the exact numbers but know that lesser amounts of rain are forecast for places like Lafayette and Kokomo and the totals will be much less north of those areas too. Models tend to be consistent with bringing the heaviest rain near and south of I-70 through Monday. Expect the potential for flash flooding and flooding.

A warm front will lift north across central Indiana Sunday night into Monday. This, along with other ingredients, will bring a risk of severe weather to parts of southwest Indiana from the hours of about 8 p.m. Sunday into early Monday morning. Storm threats will be damaging winds, hail or a tornado but much of the severe threat depends on the early day rains. Keep this in mind if your travel plans take you that direction for the holiday weekend.

Thunderstorms are also possible across central Indiana early Monday.

The heaviest rainfall will move out Monday morning with scattered showers and t-storms lingering through the afternoon and evening. We've got our fingers crossed that the rain will be cleared by the time the fireworks go at 10 p.m. Monday! It will be warm and humid on Monday with highs in the upper 70s.
