Day 1 Convective Outlook

...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF MN
AND THE EASTERN DAKOTAS...

...SUMMARY...
Isolated severe thunderstorms will remain possible from northern
Minnesota to northeast South Dakota through this evening. Large hail
and damaging winds should be the primary hazards.

...20Z Update...
Have adjusted the Marginal and Slight Risk areas across eastern ND
based on the current position of a cold front and isolated to
scattered storms that are occurring along it. Additional robust
storm development will be possible later this afternoon as continued
diurnal heating occurs along/ahead of the front. The potential for
isolated large hail and damaging wind gusts should persist into
parts of northern and west-central MN through this evening.

Across southeast FL, the Marginal Risk has been confined to where
numerous storms are ongoing along/near the immediate coast.

.PREV DISCUSSION... /ISSUED 1108 AM CDT Thu Jul 25 2019/

...Dakotas/MN...
A progressive upper low is moving eastward across Saskatchewan, with
its associated surface cold front extending from northeast ND into
central SD.  Relatively strong heating is occurring ahead of the
front, where surface dewpoints are generally in the mid-upper 60s.
This will likely result in at least a narrow corridor of afternoon
MLCAPE values exceeding 2500 J/kg.  A few intense cells are likely
to develop along the front by late afternoon over northwest MN, with
some potential for development farther south along the front into
southeast ND/northeast SD.  Vertical shear is sufficient for
organized multicell or perhaps supercell structures capable of hail
and gusty/damaging winds.  Isolated storms should persist much of
the evening across the SLGT risk area.

...South FL...
Strong heating and very moist/unstable conditions are present across
south FL today with SBCAPE values over 3000 J/kg.  Observed and
forecast soundings show 15-25 kt westerly flow in the 1-4 km layer,
which may be sufficient to enhance outflow wind potential in the
strongest cells later today.
