Residents of Indianapolis should prepare for a mixed bag of weather conditions this week, according to the National Weather Service. A calm and sunny day with a high near 53 degrees is on tap for today, but changes are set to roll in by tonight. The NWS advises showers, primarily coming after midnight, with the temperature dropping to a low around 40. The accompanying east southeast wind, expected to pick up to around 6 mph after midnight, may not seem much, but it's certainly going to make sure to fully usher in the colder, wet conditions.

Heading into Tuesday, the forecast takes a turn with rain and the possibility of thunderstorms after 4 pm. The chance of precipitation is high, sitting at 80%, with new rainfall amounts ranging from a tenth to a quarter of an inch – though thunderstorms could drive those figures higher. "New precipitation amounts between a tenth and quarter of an inch possible" is the expected measure, but as any local knows, weather can easily defy expectations.

For those looking for a break in the rainfall, Tuesday night might offer some reprieve with the chance of rain and thunderstorms decreasing before 7 pm. Cloudiness will persist, and temperatures will hover around 41 degrees, with a northeast wind around 6 mph. The NWS puts the odds of precipitation at 30%, a notable decrease from earlier in the day. An overcast Wednesday with a high near 53 follows, featuring an east northeast wind moving at a leisurely 3 to 5 mph.

The latter half of the week doesn't look much drier. "Rain likely, mainly after 1pm," reads the forecast for Thursday, with an estimated 70% chance of precipitation. It's a similar story for Thursday night into Friday—rain and potential thunderstorms are on the schedule, continuing the week's trend. By Friday night, there's still a 50 percent chance of rain in an otherwise mostly cloudy sky, with a low around 45 degrees. For the full rundown of this week's weather, including a more optimistic Saturday forecast with only a 20 percent chance of rain and partly sunny skies, visit the National Weather Service website for updates and details.
