TOLEDO, Ohio -
Across most of Northwest Ohio, you won't be seeing additional Frost Advisories or Freeze Warnings this fall. The National Weather Service only issues these alerts during the growing season. The growing season ends when temperatures fall several degrees below freezing for the first time each fall. Typically, an overnight low of around 28° will produce a "hard freeze", serving to end the growing season.
Earlier this week, Toledo chilled down to 29°. A couple of the National Weather Service offices that cover the Ohio part of the 13abc viewing area have said that for most of the counties in our area, the growing season has now ended, so you won't see these alerts issued again until the coldest mornings of the spring.
One exception to this is for the counties immediately south of Lake Erie. Places like Port Clinton, the Marblehead Peninsula and Sandusky have been protected by the 54°-58° waters of Lake Erie, so they have yet to see their first hard freeze. There, the growing season will continue, but not for long. Additionally, the NWS in Detroit, Michigan will continue to issue warnings for a short time. Freeze Warnings are in effect across southeastern Michigan.
