TODAY A chilly start with areas of frost early, then clouds increase through the day and the breeze picks up by afternoon. Highs reach the upper 50s to near 60, with a southwest wind around 10 to 15 mph and gusts up to 30 mph. Most of the day looks dry in Indianapolis, though an isolated shower cannot be ruled out north of the city late.   TONIGHT Partly cloudy and cold, with lows in the mid 30s and lighter north wind as the night goes on. Frost is likely again by daybreak, and some colder suburbs could briefly touch freezing, so this is another night to protect any sensitive plants.   TOMORROW Bright and cool with sunshine taking over after a frosty start. Highs recover to the upper 50s, and winds stay light enough to make this a much more comfortable day than the chilly start might suggest. It is a solid afternoon for errands, yard work, and anything outdoors.   TOMORROW NIGHT Mostly clear and seasonably chilly, with lows around the lower 40s. Winds stay light early, then begin to turn from the south late at around 5 mph, setting the stage for a much bigger warmup on Tuesday. Quiet weather continues with no travel concerns. TUESDAY This is where the pattern really flips. Mostly sunny skies and a stronger southwest breeze push highs into the mid 70s, with gusts up to 25 mph at times. After the cold start to the week, Tuesday will feel much more like late April again, and it should be one of the better looking afternoons of the stretch.   TUESDAY NIGHT Milder and breezy with increasing clouds, lows near the upper 50s. A few showers or a rumble of thunder may arrive late, but coverage still looks fairly limited for now, so many neighborhoods may stay dry overnight.   WEDNESDAY Warm again with a mix of sunshine and passing clouds, highs in the upper 70s. Any leftover early shower chance fades, and much of the day looks dry with a light west southwest breeze around 10 mph. This keeps the warm stretch going with a very springlike feel.   WEDNESDAY NIGHT Mostly clear to partly cloudy and mild, with lows near 60. Winds stay fairly light, and it is a quiet night overall with no major issues expected.   THURSDAY The warmest day of this week, with mostly sunny skies and highs around the lower 80s. It looks dry through the daytime hours, and the air will feel more like early summer than mid April by afternoon. Great weather for outdoor plans before the next rain chance begins to creep closer beyond sunset.   7 DAY FORECAST After the frosty, cool start Sunday night into Monday morning, temperatures rebound in a hurry, jumping from the upper 50s Monday to the 70s Tuesday and Wednesday, then into the 80s Thursday. A small shower chance shows up late Tuesday into Tuesday night, but the broader signal still favors a mainly dry and warm midweek stretch. The next more meaningful rain chance looks better timed for Friday into Friday night as showers and thunderstorms become more likely ahead of the next front, followed by a cooler step down next weekend. Overall confidence is fairly high in the warming trend, with lower confidence on exactly how much of the late Tuesday shower chance reaches Indianapolis.   ...read more read less
