The time frame for possible storm activity is from Wednesday afternoon, June 14 until late Wednesday evening.
"Potential hazards would be strong to damaging winds and hail in association with any stronger storms," the National Weather Service said in a Hazardous Weather Statement issued Wednesday morning.
Up to a half-inch to three-quarters of an inch of rainfall is expected from the system.
The system is expected to push east-northeastward starting around midday Wednesday with the passage of the frontal system.
After it pushes through by late Wednesday evening, Thursday, June 15 will be the pick of the week, with mostly sunny skies and a high temperature in the upper 70s.
But it won't last long with more unsettled weather expected on Friday, June 16, and Saturday, June 17.
