Mid-Spring Frost/Freeze???

An impressive mass of cold air will spill into the region and camp out for a couple of days. Although temperatures are forecast to bottom out in the low 30's for several locations, the NWS office in Louisville in conjunction with neighboring offices have decided to withhold any official advisories, watches, and warnings for the time being.

While tonight's readings will be cold enough to support frost, winds should keep the atmosphere mixed, not allowing frost development.

However, in sheltered areas, winds may decouple just enough for the formation of patchy frost.

Tomorrow night, winds should relax enough for more widespread frost, especially across the bluegrass, along the Cumberland River, and the usual cold spots in Breckinridge and Meade counties just southwest of Louisville.

Although the NWS Louisville is not putting out any official products other than a HWO or SPS, I think frost/freeze products will go up for areas, primarily south and east of Louisville for Friday morning.

Hang in there you green thumb enthusiasts. Your garden-planting days are coming. My ground is still way too wet to till anyway.
