Storms with strong low-level rotation developed along a warm front during the evening of May 22, 2004.
The low-level thermodynamic environment improved from marginal to favorable south of the front, but remained unfavorable north of the front through-out the event.
Mid-level storm relative flow was weak to marginal for tornadoes throughout the course of the event along and south of the front.
LCL heights were near the top end of the range of values typically associated with significant tornadoes along and south of the front.
At least two of the storms that developed, exhibited low-level rotation often associated with tornadoes in our area.
Accurate, real-time evaluation of the storm environment remains a critical, yet extremely difficult challenge for tornado warning forecasters.
