[html]MD 1682 CONCERNING SEVERE POTENTIAL...WATCH UNLIKELY FOR NORTH-CENTRAL AND EASTERN AL
Mesoscale Discussion 1682
NWS Storm Prediction Center Norman OK
0350 PM CDT Mon Aug 15 2022
Areas affected...north-central and eastern AL
Concerning...Severe potential...Watch unlikely
Valid 152050Z - 152245Z
Probability of Watch Issuance...20 percent
SUMMARY...Strong to locally severe gusts (45-60 mph) capable of
pockets of wind damage are possible through the early evening. The
limited coverage of damaging gusts will likely preclude the need for
a small severe thunderstorm watch.
DISCUSSION...Visible-satellite and radar imagery shows a developing
cluster of intensifying thunderstorms straddling I-65 in
north-central AL as of 345pm CDT. The Birmingham 88D VAD shows
westerly low-level flow veering to northerly and increasing into the
25-30 kt range in the 4-6 km layer. The mean wind will favor
southeast storm motions with this activity moving into the
Birmingham and Anniston areas over the next 1-2 hours. The airmass
has beco*e moderately unstable with lower 90s temperatures and
dewpoints near 70 deg F. With 0-3 km lapse rates in excess of 8 deg
C/km, water loading will be the primary mechanism for isolated wet
microbursts.
