1214 PM CDT Wed Jul 22 2026

Areas affected...A large portion of Maine

Concerning...Severe potential...Watch possible

Valid 221714Z - 221845Z

Probability of Watch Issuance...40 percent

SUMMARY...A gradual increase in storm coverage and intensity is
expected through the afternoon. A watch may be needed.

DISCUSSION...Storms have started to develop across western Maine
where temperatures are in the mid 70s with dewpoints in the mid 60s
F. Continued heating ahead of this activity will result in greater destabilization this afternoon and additional storm coverage. 35 to
40 knots of shear is in place (per SPC mesoanalysis and regional
VWPs) which will aid in storm organization including some supercell
structures. The relatively weak instability casts some doubt on the
total coverage of severe storms, but if several severe storms can
develop, a severe thunderstorm watch may need to be issued.
