.PREV DISCUSSION... /ISSUED 1130 AM CDT Sun Mar 20 2022/
...Southern Florida...
A cold front will continue to settle southward across the region
through afternoon and evening. Although upper heights will rise and
convergence will tend to weaken the remainder of the day, a
residually moist low-level air mass, ample insolation/heating, and
weak boundary-layer inhibition should allow for isolated
thunderstorm development during the mid/late afternoon hours,
initially near the I-75 general vicinity (and south). A couple of
multicellular clusters may evolve in the presence of 20-30 kt
effective shear. Locally strong wind gusts and small to marginally
severe hail appear to be the most likely hazards, before convection
weakens after sunset over the Upper Keys/Florida Straits.
