Greensboro, NC -- After an unseasonably cold day on Wednesday conditions are primed for frost and near freezing temperatures in the Triad by Thursday morning.
Canadian high pressure has slowly pushed south over the last couple of days to bring some of the coldest air to the Triad since early March. Temperatures Wednesday afternoon peaked nearly 15 degrees below normal with highs in the middle 50s.
The chilly northeasterly flow will continue to pump the abnormally cool air into the Triad overnight Wednesday into Thursday morning. Under a clear sky and calming winds, by Thursday morning temperatures are expected to drop to near freezing in many locations across the Triad.
As a result a Freeze Warning has been issued for the entire area from 4am-9am Thursday. During this period temperatures will be near 32 degrees and vegetation could suffer damage if not protected or brought indoors.
Areas of frost will likely develop during the time slightly before and immediately after sunrise, but will then quickly melt as the sun rises higher in the sky.
Temperatures will continue to warm through the day on Thursday and reach into the low-middle 60s for afternoon highs.
From Minnesota to Alabama to right here in North Carolina, a total of 18 states had Freeze Warnings in effect going into Wednesday Night. The average last spring freeze in the Triad is April 11th. In 2011 the last spring freeze was on April 6th.
