Rain switches to snow overnight for some in central Indiana
It's been quite a temperature tumble today from the low 70s at midnight to the lower 40s this afternoon - and the coldest is yet to come.
The transition from the summer air to winter-like lows in the 20s tonight will be accompanied by a period of wet snow in central Indiana. Drizzle and rain showers continue into the evening as temperatures continue to fall behind the passage of a cold front around midday.
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 9:00 p.m. and midnight with potential for an axis of moderate to heavy snow to pivot through between midnight and 5:00 am. The ground will be warm enough to melt most snow but some areas may see a minor slushy/grassy accumulation where it snows hard enough to overcome the warm ground.
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 before our next round of rain arrives Friday afternoon and evening.
Have a great day!
