Concerning...Severe potential...Watch unlikely Valid 301847Z - 302015Z Probability of Watch Issuance...5 percent SUMMARY...A few strong to isolated severe storms are possible this afternoon and evening. DISCUSSION...Very strong instability (3000-3500 J/kg MLCAPE per SPC mesoanalysis) has developed across Alabama and Georgia where dewpoints are in the mid 70s with temperatures in the low to mid 90s. Lapse rates are quite weak, but with minimal inhibition and very strong instability, robust updrafts are anticipated. Deep-layer shear is quite weak which will limit storm organization somewhat. However, there is a stronger belt of flow (25-30 knots) sampled by the MXX VWP between 4 and 6 km. This may assist in some storm organization in an otherwise unfavorable deep-layer shear environment. This combination of instability and some mid-level flow may result in a few multicell storms capable of damaging wind gusts. However, a more organized severe weather threat is not anticipated and therefore, no watch is expected. ..Bentley/Guyer.. 06/30/2026 ...Please see www.spc.noaa.gov for graphic product...
