This is a partial listing of significant convective events that occurred across some part of the FWD CWA during 2005. These are all of the events listed that have AWIPS archived data available. The listing for each event includes the archived data that is available for each case. The list will be updated as the convective season progresses. Email the SOO if you would like more information.

March 21, 2005

Isolated severe thunderstorms occurred along and ahead of a dryline. Marginal instability limited the overall intensity and coverage of convection. However, two F0 tornadoes occurred around 00Z on 22 March 2005 in the environment characterized by intense low and mid level shear. One tornado was photographed by a storm chaser in Lamar County near and south of Paris; another was photographed by a spotter in Falls County.  Convective towers developed along the dryline during the late afternoon, possibly where HCRs intersected the convergence boundary.  Radar appearance of both tornadic storms were unimpressive with low (<50 dBz) and elongated reflectivities; spotter reports suggested storms had identifiable supercell characteristics.

Several hail reports during the Z day of Saturday, 3/26/05. Several clusters of elevated convection developed early in the morning and developed into an MCS and continued moving across the CWA during the day. Times of reported hail range from 0912Z to 1400Z. Largest hail reported was 1.00 inch. Steep mid level lapse rates contributed to the intensity of the convection; the stationary front was in south TX with a deep shortwave trough over New Mexico.

Several severe storms developed along and ahead of dryline. Deep layer (0-6km) shear vector was nearly parallel to dryline, with 500 mb low moving across OK.  A left-moving supercell produced baseball size hail in Hamilton County at 0120Zon 4/11/05.  No TOR warnings were issued; the strongest rotation during the evening occurred with a supercell in Denton County. An 85 mph wind gust was reported with the Denton County storm. Significant training of storms resulted in locally heavy rains and a Flash Flood warning to the north of the metroplex.

Several supercell  storms developed along and ahead of a front and dryline. Deep layer (0-6km) shear was strong (around 50 kts) and the shear vector was nearly perpendicular to dryline. The most significant supercells developed in Tarrant and Johnson Counties and moved east southeast. The Tarrant County storm may have produced brief TOR touchdowns near or just west of Mansfield and near Cedar Hill. The Tarrant supercell storm eventually weakened as it moved across  extreme southern Dallas County. The Johnson County supercell eventually produced a brief TOR near Maypearl in Ellis County. Other severe storms affected parts of Grayson, Fannin, Hunt, Delta, and Hopkins Counties through the evening. No injuries or reports of significant structural damage were received.
