1059 AM CDT Fri Jul 01 2022
Areas affected...Western/northern MD...Eastern WV...Southern
PA...Northern VA...Northern DE...DC
Concerning...Severe potential...Watch unlikely
Valid 011559Z - 011830Z
Probability of Watch Issuance...20 percent
SUMMARY...Thunderstorms are expected to increase in coverage and
intensity this afternoon, with a threat of isolated damaging wind
gusts and possibly some hail.
DISCUSSION...c*nvection has gradually been increasing late this
morning across southern PA into eastern WV, within a zone of richer
moisture in the 925-850 mb layer depicted in the 12Z PIT sounding
and recent objective mesoanalyses. Diurnal heating and continued
low-level moisture transport will support an increase in
thunderstorm coverage and intensity this afternoon, as convection
gradually spreads eastward toward the I-95 corridor. MLCAPE
increasing above 2000 J/kg will support vigorous updrafts, though
marginal effective shear (generally in the 20-30 kt range) will
limit storm organization to some extent. Steepening low-level lapse
rates will support a threat of locally damaging wind gusts this
afternoon, and isolated hail will also be possible with the
strongest cells. With storm organization expected to remain rather
limited, watch issuance is considered unlikely at this time.
