Sleet and hail are hitting cities around the metro area this morning.
Small hail and graupel started falling in Golden, Arvada, Broomfield, Thornton, Boulder and Louisville at about 8 a.m.
Viewers in Frederick and Greeley reported seeing hail, sleet, rain and thunder.
Denver Airport officials reported rain and lightning moving into the area at 8:30 a.m. Officials recommended travelers check their flight status with their airline.
"There is a strong line from I-25 and Hampden, down through Greenwood Village, toward Parker," 7NEWS Weather Anchor Dayle Cedars said at 8:40 a.m.
Most of the heavy rain and hail had pushed east of the metro area by 9:15 a.m., Cedars reported. A line of storm cells was moving along 470 up toward Bennett.
"This is moving pretty quick, so it will drop and then push out," Cedars said. "But more will follow."
A new storm will drift into the region Thursday night and Friday with more mountain snow and a small chance for rain and snow for the Denver area.
