Hail in Cherokee County, Texas

Quarter size hail reported near the Cherokee County Airport.

Robust thunderstorm development began late in the evening on March 14th through the morning hours on March 15th along a dryline from the Hot Springs region southward toward Texarkana and into parts of East Texas. Upper air analysis suggested that low to mid-level winds were not quite as strong as compared to areas farther to the north. However, a strengthening low-level jet sampled by KSHV supported 0-1 km storm relative helicity (SRH) on the order of 200-300 m2/s2. Increasing low-level surface moisture and mixed layer CAPE were supportive of a more volatile environment downstream of the developing convection. Discrete to semi-discrete supercells migrated into this air mass with several reports of large hail across East Texas through the early morning hours on March 15th.
