SOUTH CAROLINA WEATHER AND CLIMATE

June 21 - 27, 2004


WEATHER SUMMARY

The first official day of Summer 2004 began with stormy weather conditions. An unstable air mass on Monday contributed to cloud heights rising beyond 60,000 feet and flooding rains over the midlands. Unofficial rainfall amounts exceeding six inches fell in Lexington County. Severe storms and associated high winds on Wednesday caused power outages over eastern counties. Heavy thunderstorms on Friday night resulted in more flash flooding upstate and at least one confirmed tornado in Anderson County. A frontal boundary positioned itself from west to east through central South Carolina Saturday and became the focus for repeated multi-cell storm development during the late afternoon hours Sunday. One inch hail, damaging winds and widespread flooding were observed. Intense cloud to ground lightning was blamed on several structure fires. The increased coverage of the daily rains helped reduce topsoil stress caused by the months of dry weather. For the period, the state average temperature was near normal.

The highest official temperature reported was 95 degrees at Darlington on June 23. The lowest official temperature reported was 61 degrees at Caesars Head on the morning of June 21. The heaviest 24 hour rainfall reported was 3.70" at Salem ending at 7:00 a.m. on June 23. The average statewide rainfall for the period was 1.2.
