Temperatures will hold nearly steady overnight as warmer air starts moving in from the south. A warm front will arrive as a few showers Sunday morning. You will also notice more clouds on Sunday as well.
Temperatures climb easily on the south wind Sunday. Highs should reach the 50 degree mark. It will also be a breezy day with winds starting from the South in the morning and shifting to the Southwest by the afternoon at 10 to 20 mph.
Now let’s talk about rainfall chances during the day. Any rain showers early Sunday morning will be associated with the lifting warm front. This period of rain will be short-lived and the best chance will be in our western counties from 3 AM to 7 AM. Isolated showers will remain possible through the noon hour but then a better wave of rain will start moving in Sunday afternoon. At this point, it does not look like thunderstorms will accompany the showers. Spotty showers will remain possible through 10 PM and then the rain coverage will start decreasing as cold air arrives to Central Indiana.
The average of 6 weather models places .45″ of rain in Indianapolis for Sunday with the heaviest falling Sunday afternoon.
Colder air will push in on Monday behind the cold front. Temperatures should only reach the low 40s that afternoon with partly cloudy conditions and breezy winds. We’ll see two cool days for Tuesday and Wednesday with near seasonal highs but temperatures will start to climb ahead of our next clipper system. This means highs in the mid 40s on Thursday before sharply colder air arrives for the weekend.
