South Carolina Ground-level Ozone Forecast Discussion

Forecast Issued: 3:05PM EDT WED 3-APR-2012

A surface low pressure system is developing over the northwestern Gulf of Mexico, while a cool and initially dry ridge of high pressure is slipping southward east of the Appalachians on this Wednesday afternoon. Mostly cloudy skies and cool NE winds ahead of this system have kept ground level ozone concentrations within the GREEN category statewide. Low pressure over the northern Gulf of Mexico will slip E'wd towards the Carolina coast on Thursday. This feature should inject enough moisture into the state to make for a cloudy and rather showery day. Expect quite raw weather conditions for April standards as a wedge remains over the Carolina Piedmont and rain moves in as the disturbance slides over the cool dome at the surface. Under such cool and moist conditions, ozone levels will remain rather low within the GREEN category on Thursday.
