Clear skies tonight will allow temperatures to drop into the mid 30s in most locations. At the very least, we expect to see patchy frost, mainly in the valleys and other typical cold spots. A hard freeze is not expected, but some of the coldest areas could briefly drop to 32 degrees. We will also have another chance for frost on Thursday morning, so if you have sensitive outdoor plants, you'll want to keep an eye on the forecast for the next few days.
Remember that some of our colder protected valleys may see widespread frost. Even with air temperatures at eye level as warm as 36 degrees, the ground can still be cold enough for frost to form.
