Much of Central Alabama In A Marginal Risk For Severe Storms On Saturday
The Storm Prediction Center has nearly all of Central Alabama south of a line from Reform to Birmingham to Wedowee in a Marginal Risk for severe storms on its day one outlook (6 AM Sat. – 6 AM Sun.). All modes of severe weather will be possible in the risk area… isolated damaging wind gusts up to 60 MPH, marginally severe hail, and a few isolated tornadoes.
With Central Alabama being in a very moist and warm airmass, the atmosphere will be marginally supportive of supercells with a low-end threat for damaging winds and an isolated tornado or two. Marginally severe hail is possible but will be limited by modest mid-level lapse rates.
Convective development will be likely during the late morning through the mid-afternoon hours as surface-based instability values will be in the 500-750 J/kg range, and shear values will be high enough to support rotating updrafts. Dewpoints will be reaching the lower to mid-60s by the mid-afternoon hours as well.
