Rain changes to period of slushy snow for some tonight

Here comes the cold. The transition from summer-ish 70s this past weekend and while you were sleeping, to winter-like lows in the 20s tonight will be accompanied by a period of wet snow in central Indiana.

Periods of gusty rain showers continue into the afternoon as temperatures slide into the lower/middle 40s by 5pm behind the passage of a cold front at midday today.

Colder air aloft catches up with residual moisture behind the front, and we're expecting a transition from rain to wet snow "between" the hours of 9pm and 12am… with potential for an axis of moderate/heavy snow to pivot through central Indiana between 12am and 5am.

The ground will likely be warm enough to melt most snow, however some areas may see a minor slushy/grassy accumulation where it snows hard enough to overcome that warm layer. Latest modeling suggests the eastern half of the state has the best "potential" for this slushy accumulation. Snow in April is not totally unusual with Indianapolis averaging .20″ for the month. But the last "measurable" April snow in the city was 2001… and that streak may end tonight. The jolting shot of cold air may become the bigger story.

Though not record-breaking , lows tonight and Wednesday morning will be in the 20s with a widespread frost/hard freeze Wednesday morning. The record low "maximum" is 40 degrees Tuesday and will be rivaled in many areas.

This will be a 36 hour window of chilly air before sun and warmer temps return after Wednesday morning. Thursday is our "pick of the week" with sunshine and mid-60s… and this precedes our next round of rain that arrives Friday afternoon and evening. Have a great day!
