Mesoscale Discussion 2114
NWS Storm Prediction Center Norman OK
1252 PM CDT Mon Aug 24 2026

Areas affected...northern Maine

Concerning...Severe potential...Watch unlikely 

Valid 241752Z - 242015Z

Probability of Watch Issuance...20 percent

SUMMARY...Isolated severe storms capable of damaging wind gusts and
marginally severe hail appear possible this afternoon into evening.
A watch is currently not expected.

DISCUSSION...Ahead of a vigorous vorticity maximum centered over the
Champlain Valley, visible satellite imagery indicates deepening
cumulus across the discussion area amidst a warming and
destabilizing air mass with around 500 J/kg of MLCAPE. Eventual
thunderstorm development is expected later this afternoon as height
falls/cooling aloft overspread the warming boundary layer,
contributing to further air mass destabilization. The kinematic
environment features strong mid/upper-level winds, resulting in
long, straight hodographs supportive of splitting supercells with an
associated hail risk. Isolated damaging wind gusts also appear
possible owing to the steepening low-level lapse rates across the
region, which will enhance evaporative cooling in the sub-cloud
layer.
