GREENSBORO, N.C. -- A very slow moving cold front will bring widespread rain and thunderstorms to the Triad through the day on Thursday and last into Friday morning.
Rain showers will begin to move into the Foothills first around daybreak and then move east through the morning. The coverage and intensity of the rain will increase Thursday afternoon as the approaching cold front moves closer.
An area of low pressure will develop along the advancing cold front Thursday afternoon causing the storms to build in strength. In an already moisture rich environment heavy rain will become the primary concern through Thursday afternoon and evening, producing a threat for flash flooding across the Piedmont and Foothills. 1-2" of rain will be likely with more than 3" of rain possible in some locations. As a result a Flash Flood Watch has been issued for the western Piedmont, Foothills and Mountain communities. This Flash Flood Watch will remain in effect until Friday morning.
In addition to heavy rain and flash flooding, damaging winds up to 60 mph could be possible within some of the strong storms Thursday and Thursday night. These damaging winds could cause trees and limbs to fall causing localized power outages. The chance of tornadoes will remain relatively small, but even a rogue isolated tornado cannot be ruled out.
The cold front will move east of the Triad Friday morning and give way to clearing conditions Friday afternoon. Once the cold front moves east it will usher in cooler air that will hang around through the weekend. High temperatures Friday, Saturday and Sunday will be in the low-middle 70s.
