Areas affected...Northern Lower MI

Concerning...Severe potential...Watch possible=20

Valid 020538Z - 020745Z

Probability of Watch Issuance...40 percent

SUMMARY...Strong to locally severe storms remain possible overnight.

DISCUSSION...Strong storms over northern Lake Michigan are moving
into northwest Lower MI as of 0535 UTC. This portion of Lower MI is
generally north of remnant outflow, with temperatures in the upper
60s to around 70 F (compared to around 80 F south of the boundary).
However, relatively rich low-level moisture is helping to maintain
MUCAPE of near/above 2000 J/kg early this morning, with moderate
deep-layer flow/shear (observed on the KAPX VWP) supporting some organized-storm potential.=20

The small storm cluster approaching northwest Lower MI may persist
into at least north-central Lower MI overnight. Damaging-wind
potential will accompany this cluster, though near-surface stability
may mitigate this threat to some extent. Other discrete convection
developing in advance of this cluster could pose a threat of
localized wind damage and isolated hail, if these storms are able to
mature.=20

Given the somewhat elevated nature of ongoing convection, the
magnitude of the wind threat is uncertain, but trends will be
monitored for increasing wind-damage potential and possible watch
issuance.
