Cold tonight leads to frost advisory, freeze warning

Overnight temperatures will fall through the 40s as clouds clear out and the breeze diminishes, StormCenter 7 Meteorologsit Rich Wirdzek said.

These variables will allow for even colder air, with low temps near freezing.

Key weather points:

  • Freeze possible, scattered frost likely
  • More frost Thursday night
  • Showers by the weekend

Temperatures in low lying spots and areas far north and west of Dayton will drop into the upper 20s, a long enough time below freezing to constitute the threat of a freeze. Elsewhere, it will be cold enough for frost.

Thursday: The call for frost-producing cold prompted the National Weather Service to issue a freeze warning or frost advisory, from 4 to 8 a.m. for the following counties: Auglaize, Champaign, Darke, Logan, Mercer, Miami, Shelby and Preble in Ohio, along with Wayne and Randolph in Indiana.

The advisory is for Butler, Clark, Clinton, Greene, Montgomery and Warren counties.

We’ll have clear skies again Thursday night and little to no breeze. It won’t be cold enough for a freeze, but frost is again a possibility in many spots. Lows in the mid 30s.

Friday: Mostly sunny skies with more clouds arriving late in the day. Highs in the mid- to upper 50s.

Saturday: Increasing clouds with some showers. Highs in the low 50s.

Sunday: Clouds give way to sun. It will be a bit milder. Highs near 60.

Monday: Partly cloudy with highs in the low 60s.
