Areas affected...Portions of central and northern Minnesota
Concerning...Severe potential...Watch possible=20
Valid 162039Z - 162315Z
Probability of Watch Issuance...60 percent
SUMMARY...Scattered strong to severe thunderstorms are expected this
evening.
DISCUSSION...Thunderstorms are expected to develop along or perhaps
slightly behind a cold front across northern Minnesota late this
afternoon or early this evening. This region continues to
destabilize with MLCAPE around 750 to 1000 J/kg MLCAPE and it is
expected to increase to as high as 1500 J/kg later this evening.
Currently the airmass remains capped, but additional surface heating
and cooling temperatures aloft should mostly eliminate inhibition by
around 22 UTC. Once storms form, strong mid-level flow at least
partially normal to the front should support a broken line of
supercells. Instability will start to wane quickly after sunset and
a drier airmass is present across Wisconsin. Therefore, storms may
persist for a few hours after dark but are expected to weaken by
late evening. Large hail and damaging wind gusts will be the primary
threat from this activity.
