Areas affected...Portions of southwest/south-central ND and
northwest/north-central SD
Concerning...Severe potential...Watch unlikely
Valid 072316Z - 080045Z
Probability of Watch Issuance...5 percent
SUMMARY...A localized strong to severe storm capable of marginally
severe hail and locally strong/damaging winds is possible during the
next couple hours.
DISCUSSION...Isolated thunderstorm development is underway over
southwest ND into northwest SD -- generally focused along a weak
east/west-oriented stationary boundary. This activity is developing
along the northern edge of a plume of weak surface-based
instability, and this weak instability is the main mitigating factor
for a more robust severe-storm risk. However, proximity forecast
soundings indicate strong deep-layer shear (around 60 kt of
effective shear) -- characterized by a long/straight hodograph. This
wind profile may support brief updraft organization (with transient
midlevel rotation) -- capable of producing marginally severe hail
(up to 1 inch) and locally strong/damaging winds (45-60 mph) for the
next couple hours. Overall, the weak instability should limit the
severe threat.
