Indianapolis will see a brief warm-up early this week before a more unsettled pattern returns, according to National Weather Service meteorologist Aaron Updike. After a chilly start to the week, temperatures will rebound quickly by Tuesday, followed by increasing chances for showers and thunderstorms. Today will remain cool and breezy across central Indiana, with highs in the upper 50s to near 60°F and a mix of clouds and sun. However, a stray afternoon shower is possible, but conditions should remain dry and pleasant. By Wednesday and Thursday, cloud cover will increase and the chance for showers returns as a frontal boundary moves into the region. The main concern late week will likely be rainfall totals rather than severe weather.
